Review
BACKGROUND
Lower-limb running injuries are common. Running shoes have been proposed as one means of reducing injury risk. However, there is uncertainty as to how effective running shoes are for the prevention of injury. It is also unclear how the effects of different characteristics of running shoes prevent injury.
OBJECTIVES
To assess the effects (benefits and harms) of running shoes for preventing lower-limb running injuries in adult runners.
SEARCH METHODS
We searched the following databases: CENTRAL, MEDLINE, Embase, AMED, CINAHL Plus and SPORTDiscus plus trial registers WHO ICTRP and ClinicalTrials.gov. We also searched additional sources for published and unpublished trials. The date of the search was June 2021.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) and quasi-RCTs involving runners or military personnel in basic training that either compared a) a running shoe with a non-running shoe; b) different types of running shoes (minimalist, neutral/cushioned, motion control, stability, soft midsole, hard midsole); or c) footwear recommended and selected on foot posture versus footwear not recommended and not selected on foot posture for preventing lower-limb running injuries. Our primary outcomes were number of people sustaining a lower-limb running injury and number of lower-limb running injuries. Our secondary outcomes were number of runners who failed to return to running or their previous level of running, runner satisfaction with footwear, adverse events other than musculoskeletal injuries, and number of runners requiring hospital admission or surgery, or both, for musculoskeletal injury or adverse event.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed study eligibility and performed data extraction and risk of bias assessment. The certainty of the included evidence was assessed using GRADE methodology.
MAIN RESULTS
We included 12 trials in the analysis which included a total of 11,240 participants, in trials that lasted from 6 to 26 weeks and were carried out in North America, Europe, Australia and South Africa. Most of the evidence was low or very low certainty as it was not possible to blind runners to their allocated running shoe, there was variation in the definition of an injury and characteristics of footwear, and there were too few studies for most comparisons. We did not find any trials that compared running shoes with non-running shoes. Neutral/cushioned versus minimalist (5 studies, 766 participants) Neutral/cushioned shoes may make little or no difference to the number of runners sustaining a lower-limb running injuries when compared with minimalist shoes (low-certainty evidence) (risk ratio (RR) 0.77, 95% confidence interval (CI) 0.59 to 1.01). One trial reported that 67% and 92% of runners were satisfied with their neutral/cushioned or minimalist running shoes, respectively (RR 0.73, 95% CI 0.47 to 1.12). Another trial reported mean satisfaction scores ranged from 4.0 to 4.3 in the neutral/ cushioned group and 3.6 to 3.9 in the minimalist running shoe group out of a total of 5. Hence neutral/cushioned running shoes may make little or no difference to runner satisfaction with footwear (low-certainty evidence). Motion control versus neutral / cushioned (2 studies, 421 participants) It is uncertain whether or not motion control shoes reduce the number of runners sustaining a lower-limb running injuries when compared with neutral / cushioned shoes because the quality of the evidence has been assessed as very low certainty (RR 0.92, 95% CI 0.30 to 2.81). Soft midsole versus hard midsole (2 studies, 1095 participants) Soft midsole shoes may make little or no difference to the number of runners sustaining a lower-limb running injuries when compared with hard midsole shoes (low-certainty of evidence) (RR 0.82, 95% CI 0.61 to 1.10). Stability versus neutral / cushioned (1 study, 57 participants) It is uncertain whether or not stability shoes reduce the number of runners sustaining a lower-limb running injuries when compared with neutral/cushioned shoes because the quality of the evidence has been assessed as very low certainty (RR 0.49, 95% CI 0.18 to 1.31). Motion control versus stability (1 study, 56 participants) It is uncertain whether or not motion control shoes reduce the number of runners sustaining a lower-limb running injuries when compared with stability shoes because the quality of the evidence has been assessed as very low certainty (RR 3.47, 95% CI 1.43 to 8.40). Running shoes prescribed and selected on foot posture (3 studies, 7203 participants) There was no evidence that running shoes prescribed based on static foot posture reduced the number of injuries compared with those who received a shoe not prescribed based on foot posture in military recruits (Rate Ratio 1.03, 95% CI 0.94 to 1.13). Subgroup analysis confirmed these findings were consistent between males and females. Therefore, prescribing running shoes and selecting on foot posture probably makes little or no difference to lower-limb running injuries (moderate-certainty evidence). Data were not available for all other review outcomes.
AUTHORS' CONCLUSIONS
Most evidence demonstrates no reduction in lower-limb running injuries in adults when comparing different types of running shoes. Overall, the certainty of the evidence determining whether different types of running shoes influence running injury rates was very low to low, and as such we are uncertain as to the true effects of different types of running shoes upon injury rates. There is no evidence that prescribing footwear based on foot type reduces running-related lower-limb injures in adults. The evidence for this comparison was rated as moderate and as such we can have more certainty when interpreting these findings. However, all three trials included in this comparison used military populations and as such the findings may differ in recreational runners. Future researchers should develop a consensus definition of running shoe design to help standardise classification. The definition of a running injury should also be used consistently and confirmed via health practitioners. More researchers should consider a RCT design to increase the evidence in this area. Lastly, future work should look to explore the influence of different types or running shoes upon injury rates in specific subgroups.

Exercise-Based Training Strategies to Reduce the Incidence or Mitigate the Risk Factors of Anterior Cruciate Ligament Injury in Adult Football (Soccer) Players: A Systematic Review.
Anterior cruciate ligament (ACL) is one of the most concerning injuries for football players. The aim of this review is to investigate the effects of exercise-based interventions targeting at reducing ACL injury rate or mitigating risk factors of ACL injury in adult football players. Following PRISMA guidelines, a systematic search was conducted in CINAHL, Cochrane Library, PubMed, Scopus, SPORTDiscus and Web of Science. Studies assessing the effect of exercise-based interventions in ACL injury incidence or modifiable risk factors in adult football players were included. 29 studies evaluating 4502 male and 1589 female players were included (15 RCT, 8 NRCT, 6 single-arm): 14 included warm-up, 7 resistance training, 4 mixed training, 3 balance, 1 core stability and 1 technique modification interventions. 6 out of 29 studies investigated the effect of interventions on ACL injury incidence, while the remaining 23 investigated their effect on risk factors. Only 21% and 13% studies evaluating risk of injury variables reported reliability measures and/or smallest worthwhile change data. Warm-up, core stability, balance and technique modification appear effective and feasible interventions to be included in football teams. However, the use of more ecologically valid tests and individually tailored interventions targeting specific ACL injury mechanisms are required.

The objective of this systematic review was to identify potential risk factors for injury in CrossFit participants. Embase, Medline, Web of Science, Cochrane, CINAHL, Google Scholar, and SportDiscuss databases were all searched up to June 2021. Cohort studies that investigated risk factors for CrossFit injuries requiring medical attention or leading to time loss in sports were included. A best-evidence synthesis was performed combining all the outcomes from prospective cohort studies. From 9,452 publications identified, we included three prospective cohort studies from which two had a low risk of bias and one a high risk of bias. The studies examined 691 participants of whom 172 sustained an injury. There was limited evidence that switching between prescribed and scaled loads during training is associated with increased injury risk and that increased duration of participation is a protective factor for injury. This could mean that novice CrossFit athletes and those increasing their training load should have closer supervision by CrossFit coaches. These risk factors should be considered when developing preventive interventions.

Meta-Analysis
Background Patients with fractures are a common emergency presentation and may be misdiagnosed at radiologic imaging. An increasing number of studies apply artificial intelligence (AI) techniques to fracture detection as an adjunct to clinician diagnosis. Purpose To perform a systematic review and meta-analysis comparing the diagnostic performance in fracture detection between AI and clinicians in peer-reviewed publications and the gray literature (ie, articles published on preprint repositories). Materials and Methods A search of multiple electronic databases between January 2018 and July 2020 (updated June 2021) was performed that included any primary research studies that developed and/or validated AI for the purposes of fracture detection at any imaging modality and excluded studies that evaluated image segmentation algorithms. Meta-analysis with a hierarchical model to calculate pooled sensitivity and specificity was used. Risk of bias was assessed by using a modified Prediction Model Study Risk of Bias Assessment Tool, or PROBAST, checklist. Results Included for analysis were 42 studies, with 115 contingency tables extracted from 32 studies (55 061 images). Thirty-seven studies identified fractures on radiographs and five studies identified fractures on CT images. For internal validation test sets, the pooled sensitivity was 92% (95% CI: 88, 93) for AI and 91% (95% CI: 85, 95) for clinicians, and the pooled specificity was 91% (95% CI: 88, 93) for AI and 92% (95% CI: 89, 92) for clinicians. For external validation test sets, the pooled sensitivity was 91% (95% CI: 84, 95) for AI and 94% (95% CI: 90, 96) for clinicians, and the pooled specificity was 91% (95% CI: 81, 95) for AI and 94% (95% CI: 91, 95) for clinicians. There were no statistically significant differences between clinician and AI performance. There were 22 of 42 (52%) studies that were judged to have high risk of bias. Meta-regression identified multiple sources of heterogeneity in the data, including risk of bias and fracture type. Conclusion Artificial intelligence (AI) and clinicians had comparable reported diagnostic performance in fracture detection, suggesting that AI technology holds promise as a diagnostic adjunct in future clinical practice.

Meta-Analysis
BACKGROUND
This study aims to compare conservative versus surgical management for patients with full-thickness RC tear in terms of clinical and structural outcomes at 1 and 2 years of follow-up.
METHODS
A comprehensive search of CENTRAL, MEDLINE, EMBASE, CINAHL, Google Scholar and reference lists of retrieved articles was performed since the inception of each database until August 2020. According to the Cochrane Handbook for Systematic Reviews of Interventions, two independent authors screened all suitable studies for the inclusion, extracted data and assessed risk of bias. Only randomised controlled trials comparing conservative and surgical management of full-thickness RC tear in adults were included. The primary outcome measure was the effectiveness of each treatment in terms of Constant-Murley score (CMS) and VAS pain score at different time points. The secondary outcome was the integrity of the repaired tendon evaluated on postoperative MRI at different time points. The GRADE guidelines were used to assess the critical appraisal status and quality of evidence.
RESULTS
A total of six articles met the inclusion criteria. The average value of CMS score at 12 months of follow-up was 77.6 ± 14.4 in the surgery group and 72.8 ± 16.5 in the conservative group, without statistically significant differences between the groups. Similar results were demonstrated at 24 months of follow-up. The mean of VAS pain score at 12 months of follow-up was 1.4 ± 1.6 in the surgery group and 2.4 ± 1.9 in the conservative group. Quantitative synthesis showed better results in favour of the surgical group in terms of VAS pain score one year after surgery (- 1.08, 95% CI - 1.58 to - 0.58; P < 0.001).
CONCLUSIONS
At a 2-year follow-up, shoulder function evaluated in terms of CMS was not significantly improved. Further high-quality level-I randomised controlled trials at longer term follow-up are needed to evaluate whether surgical and conservative treatment provide comparable long-term results.

Review
BACKGROUND
Rupture of the anterior cruciate ligament (ACL) is a common injury, mainly affecting young, physically active individuals. The injury is characterised by joint instability, leading to decreased activity, which can lead to poor knee-related quality of life. It is also associated with increased risk of secondary osteoarthritis of the knee. It is unclear whether stabilising the knee surgically via ACL reconstruction produces a better overall outcome than non-surgical (conservative) treatment.
OBJECTIVES
To assess the effects of surgical versus conservative interventions for treating ACL injuries.
SEARCH METHODS
We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (18 January 2016), the Cochrane Central Register of Controlled Trials (2016, Issue 1), MEDLINE (1946 to January Week 1 2016), MEDLINE In-Process & Other Non-Indexed Citations (18 January 2016), EMBASE (1974 to 15 January 2016), trial registers (February 2016) and reference lists.
SELECTION CRITERIA
We included randomised controlled trials that compared the use of surgical and conservative interventions in participants with an ACL rupture. We included any trial that evaluated surgery for ACL reconstruction using any method of reconstruction, type of reconstruction technique, graft fixation or type of graft.
DATA COLLECTION AND ANALYSIS
Three review authors independently screened all titles and abstracts for potentially eligible studies, for which we then obtained full-text reports. Two authors then independently confirmed eligibility, extracted data and assessed the risk of bias using the Cochrane 'Risk of bias' tool. We used the GRADE approach to assess the overall quality of the evidence.
MAIN RESULTS
We identified one study in which 141 young, active adults with acute ACL injury were randomised to either ACL reconstruction followed by structured rehabilitation (results reported for 62 participants) or conservative treatment comprising structured rehabilitation alone (results reported for 59 participants). Built into the study design was a formal option for subsequent (delayed) ACL reconstruction in the conservative treatment group, if the participant requested surgery and met pre-specified criteria.This study was deemed at low risk of selection and reporting biases, at high risk of performance and detection biases because of the lack of blinding and at unclear risk of attrition bias because of an imbalance in the post-randomisation exclusions. According to GRADE methodology, the overall quality of the evidence was low across different outcomes.This study identified no difference in subjective knee score (measured using the average score on four of the five sub-scales of the KOOS score (range from 0 (extreme symptoms) to 100 (no symptoms)) between ACL reconstruction and conservative treatment at two years (difference in KOOS-4 change from baseline scores: MD -0.20, 95% confidence interval (CI) -6.78 to 6.38; N = 121 participants; low-quality evidence), or at five years (difference in KOOS-4 final scores: MD -2.0, 95% CI -8.27 to 4.27; N = 120 participants; low-quality evidence). The total number of participants incurring one or more complications in each group was not reported; serious events reported in the surgery group were predominantly surgery-related, while those in conservative treatment group were predominantly knee instability. There were also incomplete data for total participants with treatment failure, including subsequent surgery. In the surgical group at two years, there was low-quality evidence of far fewer ACL-related treatment failures, when defined as either graft rupture or subsequent ACL reconstruction. This result is dominated by the uptake by 39% (23/59) of the participants in the conservative treatment group of ACL reconstruction for knee instability at two years and by 51% (30/59) of the participants at five years. There was low-quality evidence of little difference between the two groups in participants who had undergone meniscal surgery at anytime up to five years. There was low-quality evidence of no clinically important between-group differences in SF-36 physical component scores at two years. There was low-quality evidence of a higher return to the same or greater level of sport activity at two years in the ACL reconstruction group, but the wide 95% CI also included the potential for a higher return in the conservative treatment group. Based on an illustrative return to sport activities of 382 per 1000 conservatively treated patients, this amounts to an extra 84 returns per 1000 ACL-reconstruction patients (95% CI 84 fewer to 348 more). There was very low-quality evidence of a higher incidence of radiographically-detected osteoarthritis in the surgery group (19/58 (35%) versus 10/55 (18%)).
AUTHORS' CONCLUSIONS
For adults with acute ACL injuries, we found low-quality evidence that there was no difference between surgical management (ACL reconstruction followed by structured rehabilitation) and conservative treatment (structured rehabilitation only) in patient-reported outcomes of knee function at two and five years after injury. However, these findings need to be viewed in the context that many participants with an ACL rupture remained symptomatic following rehabilitation and later opted for ACL reconstruction surgery. Further research, including the two identified ongoing trials, will help to address the limitations in the current evidence, which is from one small trial in a young, active, adult population.

OBJECTIVE
To systematically review and summarise the evidence for the effects of neuromuscular training compared with any other therapy (conventional training/sham) on knee proprioception following anterior cruciate ligament (ACL) injury.
DESIGN
Systematic Review.
DATA SOURCES
PubMed, CINAHL, SPORTDiscus, AMED, Scopus and Physical Education Index were searched from inception to February 2020.
ELIGIBILITY CRITERIA
Randomised controlled trials (RCTs) and controlled clinical trials investigating the effects of neuromuscular training on knee-specific proprioception tests following a unilateral ACL injury were included.
DATA EXTRACTION AND SYNTHESIS
Two reviewers independently screened and extracted data and assessed risk of bias of the eligible studies using the Cochrane risk of bias 2 tool. Overall certainty in evidence was determined using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) tool.
RESULTS
Of 2706 articles retrieved, only 9 RCTs, comprising 327 individuals with an ACL reconstruction (ACLR), met the inclusion criteria. Neuromuscular training interventions varied across studies: whole body vibration therapy, Nintendo-Wii-Fit training, balance training, sport-specific exercises, backward walking, etc. Outcome measures included joint position sense (JPS; n=7), thresholds to detect passive motion (TTDPM; n=3) or quadriceps force control (QFC; n=1). Overall, between-group mean differences indicated inconsistent findings with an increase or decrease of errors associated with JPS by ≤2°, TTDPM by ≤1.5° and QFC by ≤6 Nm in the ACLR knee following neuromuscular training. Owing to serious concerns with three or more GRADE domains (risk of bias, inconsistency, indirectness or imprecision associated with the findings) for each outcome of interest across studies, the certainty of evidence was very low.
CONCLUSIONS
The heterogeneity of interventions, methodological limitations, inconsistency of effects (on JPS/TTDPM/QFC) preclude recommendation of one optimal neuromuscular training intervention for improving proprioception following ACL injury in clinical practice. There is a need for methodologically robust RCTs with homogenous populations with ACL injury (managed conservatively or with reconstruction), novel/well-designed neuromuscular training and valid proprioception assessments, which also seem to be lacking.

Review
BACKGROUND
Recent investigations on the biochemical pathways after a musculoskeletal injury have suggested that vitamin C (ascorbic acid) may be a viable supplement to enhance collagen synthesis and soft tissue healing.
PURPOSE
To (1) summarize vitamin C treatment protocols; (2) report on the efficacy of vitamin C in accelerating healing after bone, tendon, and ligament injuries in vivo and in vitro; and (3) report on the efficacy of vitamin C as an antioxidant protecting against fibrosis and promoting collagen synthesis.
STUDY DESIGN
Systematic review; Level of evidence, 2.
METHODS
A systematic review was performed, with the inclusion criteria of animal and human studies on vitamin C supplementation after a musculoskeletal injury specific to collagen cross-linking, collagen synthesis, and biologic healing of the bone, ligament, and tendon.
RESULTS
The initial search yielded 286 articles. After applying the inclusion and exclusion criteria, 10 articles were included in the final analysis. Of the preclinical studies evaluating fracture healing, 2 studies reported significantly accelerated bone healing in the vitamin C supplementation group compared with control groups. The 2 preclinical studies evaluating tendon healing reported significant increases in type I collagen fibers and scar tissue formation with vitamin C compared with control groups. The 1 preclinical study after anterior cruciate ligament (ACL) reconstruction reported significant short-term (1-6 weeks) improvements in ACL graft incorporation in the vitamin C group compared with control groups; however, there was no long-term (42 weeks) difference. Of the clinical studies evaluating fracture healing, 1 study reported no significant differences in the rate of fracture healing at 50 days or functional outcomes at 1 year. Vitamin C supplementation was shown to decrease oxidative stress parameters by neutralizing reactive oxygen species through redox modulation in animal models. No animal or human studies reported any adverse effects of vitamin C supplementation.
CONCLUSION
Preclinical studies demonstrated that vitamin C has the potential to accelerate bone healing after a fracture, increase type I collagen synthesis, and reduce oxidative stress parameters. No adverse effects were reported with vitamin C supplementation in either animal models or human participants; thus, oral vitamin C appears to be a safe supplement but lacks clinical evidence compared with controls. Because of the limited number of human studies, further clinical investigations are needed before the implementation of vitamin C as a postinjury supplement.

Review
OBJECTIVE
The aim of this study was to systematically review dextrose (d-glucose) prolotherapy efficacy in the treatment of chronic musculoskeletal pain.
DATA SOURCES
Electronic databases PubMed, Healthline, OmniMedicalSearch, Medscape, and EMBASE were searched from 1990 to January 2016.
STUDY SELECTION
Prospectively designed studies that used dextrose as the sole active prolotherapy constituent were selected.
DATA EXTRACTION
Two independent reviewers rated studies for quality of evidence using the Physiotherapy Evidence Database assessment scale for randomized controlled trials (RCTs) and the Downs and Black evaluation tool for non-RCTs, for level of evidence using a modified Sackett scale, and for clinically relevant pain score difference using minimal clinically important change criteria. Study population, methods, and results data were extracted and tabulated.
DATA SYNTHESIS
Fourteen RCTs, 1 case-control study, and 18 case series studies met the inclusion criteria and were evaluated. Pain conditions were clustered into tendinopathies, osteoarthritis (OA), spinal/pelvic, and myofascial pain. The RCTs were high-quality Level 1 evidence (Physiotherapy Evidence Database ≥8) and found dextrose injection superior to controls in Osgood-Schlatter disease, lateral epicondylitis of the elbow, traumatic rotator cuff injury, knee OA, finger OA, and myofascial pain; in biomechanical but not subjective measures in temporal mandibular joint; and comparable in a short-term RCT but superior in a long-term RCT in low back pain. Many observational studies were of high quality and reported consistent positive evidence in multiple studies of tendinopathies, knee OA, sacroiliac pain, and iliac crest pain that received RCT confirmation in separate studies. Eighteen studies combined patient self-rating (subjective) with psychometric, imaging, and/or biomechanical (objective) outcome measurement and found both positive subjective and objective outcomes in 16 studies and positive objective but not subjective outcomes in two studies. All 15 studies solely using subjective or psychometric measures reported positive findings.
CONCLUSION
Use of dextrose prolotherapy is supported for treatment of tendinopathies, knee and finger joint OA, and spinal/pelvic pain due to ligament dysfunction. Efficacy in acute pain, as first-line therapy, and in myofascial pain cannot be determined from the literature.

Review
BACKGROUND
Improving mobility outcomes after hip fracture is key to recovery. Possible strategies include gait training, exercise and muscle stimulation. This is an update of a Cochrane Review last published in 2011.
OBJECTIVES
To evaluate the effects (benefits and harms) of interventions aimed at improving mobility and physical functioning after hip fracture surgery in adults.
SEARCH METHODS
We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, trial registers and reference lists, to March 2021.
SELECTION CRITERIA
All randomised or quasi-randomised trials assessing mobility strategies after hip fracture surgery. Eligible strategies aimed to improve mobility and included care programmes, exercise (gait, balance and functional training, resistance/strength training, endurance, flexibility, three-dimensional (3D) exercise and general physical activity) or muscle stimulation. Intervention was compared with usual care (in-hospital) or with usual care, no intervention, sham exercise or social visit (post-hospital).
DATA COLLECTION AND ANALYSIS
Members of the review author team independently selected trials for inclusion, assessed risk of bias and extracted data. We used standard methodological procedures expected by Cochrane. We used the assessment time point closest to four months for in-hospital studies, and the time point closest to the end of the intervention for post-hospital studies. Critical outcomes were mobility, walking speed, functioning, health-related quality of life, mortality, adverse effects and return to living at pre-fracture residence.
MAIN RESULTS
We included 40 randomised controlled trials (RCTs) with 4059 participants from 17 countries. On average, participants were 80 years old and 80% were women. The median number of study participants was 81 and all trials had unclear or high risk of bias for one or more domains. Most trials excluded people with cognitive impairment (70%), immobility and/or medical conditions affecting mobility (72%). In-hospital setting, mobility strategy versus control Eighteen trials (1433 participants) compared mobility strategies with control (usual care) in hospitals. Overall, such strategies may lead to a moderate, clinically-meaningful increase in mobility (standardised mean difference (SMD) 0.53, 95% confidence interval (CI) 0.10 to 0.96; 7 studies, 507 participants; low-certainty evidence) and a small, clinically meaningful improvement in walking speed (CI crosses zero so does not rule out a lack of effect (SMD 0.16, 95% CI -0.05 to 0.37; 6 studies, 360 participants; moderate-certainty evidence). Mobility strategies may make little or no difference to short-term (risk ratio (RR) 1.06, 95% CI 0.48 to 2.30; 6 studies, 489 participants; low-certainty evidence) or long-term mortality (RR 1.22, 95% CI 0.48 to 3.12; 2 studies, 133 participants; low-certainty evidence), adverse events measured by hospital re-admission (RR 0.70, 95% CI 0.44 to 1.11; 4 studies, 322 participants; low-certainty evidence), or return to pre-fracture residence (RR 1.07, 95% CI 0.73 to 1.56; 2 studies, 240 participants; low-certainty evidence). We are uncertain whether mobility strategies improve functioning or health-related quality of life as the certainty of evidence was very low. Gait, balance and functional training probably causes a moderate improvement in mobility (SMD 0.57, 95% CI 0.07 to 1.06; 6 studies, 463 participants; moderate-certainty evidence). There was little or no difference in effects on mobility for resistance training. No studies of other types of exercise or electrical stimulation reported mobility outcomes. Post-hospital setting, mobility strategy versus control Twenty-two trials (2626 participants) compared mobility strategies with control (usual care, no intervention, sham exercise or social visit) in the post-hospital setting. Mobility strategies lead to a small, clinically meaningful increase in mobility (SMD 0.32, 95% CI 0.11 to 0.54; 7 studies, 761 participants; high-certainty evidence) and a small, clinically meaningful improvement in walking speed compared to control (SMD 0.16, 95% CI 0.04 to 0.29; 14 studies, 1067 participants; high-certainty evidence). Mobility strategies lead to a small, non-clinically meaningful increase in functioning (SMD 0.23, 95% CI 0.10 to 0.36; 9 studies, 936 participants; high-certainty evidence), and probably lead to a slight increase in quality of life that may not be clinically meaningful (SMD 0.14, 95% CI -0.00 to 0.29; 10 studies, 785 participants; moderate-certainty evidence). Mobility strategies probably make little or no difference to short-term mortality (RR 1.01, 95% CI 0.49 to 2.06; 8 studies, 737 participants; moderate-certainty evidence). Mobility strategies may make little or no difference to long-term mortality (RR 0.73, 95% CI 0.39 to 1.37; 4 studies, 588 participants; low-certainty evidence) or adverse events measured by hospital re-admission (95% CI includes a large reduction and large increase, RR 0.86, 95% CI 0.52 to 1.42; 2 studies, 206 participants; low-certainty evidence). Training involving gait, balance and functional exercise leads to a small, clinically meaningful increase in mobility (SMD 0.20, 95% CI 0.05 to 0.36; 5 studies, 621 participants; high-certainty evidence), while training classified as being primarily resistance or strength exercise may lead to a clinically meaningful increase in mobility measured using distance walked in six minutes (mean difference (MD) 55.65, 95% CI 28.58 to 82.72; 3 studies, 198 participants; low-certainty evidence). Training involving multiple intervention components probably leads to a substantial, clinically meaningful increase in mobility (SMD 0.94, 95% CI 0.53 to 1.34; 2 studies, 104 participants; moderate-certainty evidence). We are uncertain of the effect of aerobic training on mobility (very low-certainty evidence). No studies of other types of exercise or electrical stimulation reported mobility outcomes.
AUTHORS' CONCLUSIONS
Interventions targeting improvement in mobility after hip fracture may cause clinically meaningful improvement in mobility and walking speed in hospital and post-hospital settings, compared with conventional care. Interventions that include training of gait, balance and functional tasks are particularly effective. There was little or no between-group difference in the number of adverse events reported. Future trials should include long-term follow-up and economic outcomes, determine the relative impact of different types of exercise and establish effectiveness in emerging economies.
