Meta-Analysis
BACKGROUND
Strength training or aerobic exercise programmes, or both, might optimise muscle and cardiorespiratory function and prevent additional disuse atrophy and deconditioning in people with a muscle disease. This is an update of a review first published in 2004 and last updated in 2013. We undertook an update to incorporate new evidence in this active area of research.
OBJECTIVES
To assess the effects (benefits and harms) of strength training and aerobic exercise training in people with a muscle disease.
SEARCH METHODS
We searched Cochrane Neuromuscular's Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL in November 2018 and clinical trials registries in December 2018.
SELECTION CRITERIA
Randomised controlled trials (RCTs), quasi-RCTs or cross-over RCTs comparing strength or aerobic exercise training, or both lasting at least six weeks, to no training in people with a well-described muscle disease diagnosis.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included 14 trials of aerobic exercise, strength training, or both, with an exercise duration of eight to 52 weeks, which included 428 participants with facioscapulohumeral muscular dystrophy (FSHD), dermatomyositis, polymyositis, mitochondrial myopathy, Duchenne muscular dystrophy (DMD), or myotonic dystrophy. Risk of bias was variable, as blinding of participants was not possible, some trials did not blind outcome assessors, and some did not use an intention-to-treat analysis. Strength training compared to no training (3 trials) For participants with FSHD (35 participants), there was low-certainty evidence of little or no effect on dynamic strength of elbow flexors (MD 1.2 kgF, 95% CI -0.2 to 2.6), on isometric strength of elbow flexors (MD 0.5 kgF, 95% CI -0.7 to 1.8), and ankle dorsiflexors (MD 0.4 kgF, 95% CI -2.4 to 3.2), and on dynamic strength of ankle dorsiflexors (MD -0.4 kgF, 95% CI -2.3 to 1.4). For participants with myotonic dystrophy type 1 (35 participants), there was very low-certainty evidence of a slight improvement in isometric wrist extensor strength (MD 8.0 N, 95% CI 0.7 to 15.3) and of little or no effect on hand grip force (MD 6.0 N, 95% CI -6.7 to 18.7), pinch grip force (MD 1.0 N, 95% CI -3.3 to 5.3) and isometric wrist flexor force (MD 7.0 N, 95% CI -3.4 to 17.4). Aerobic exercise training compared to no training (5 trials) For participants with DMD there was very low-certainty evidence regarding the number of leg revolutions (MD 14.0, 95% CI -89.0 to 117.0; 23 participants) or arm revolutions (MD 34.8, 95% CI -68.2 to 137.8; 23 participants), during an assisted six-minute cycle test, and very low-certainty evidence regarding muscle strength (MD 1.7, 95% CI -1.9 to 5.3; 15 participants). For participants with FSHD, there was low-certainty evidence of improvement in aerobic capacity (MD 1.1 L/min, 95% CI 0.4 to 1.8, 38 participants) and of little or no effect on knee extension strength (MD 0.1 kg, 95% CI -0.7 to 0.9, 52 participants). For participants with dermatomyositis and polymyositis (14 participants), there was very low-certainty evidence regarding aerobic capacity (MD 14.6, 95% CI -1.0 to 30.2). Combined aerobic exercise and strength training compared to no training (6 trials) For participants with juvenile dermatomyositis (26 participants) there was low-certainty evidence of an improvement in knee extensor strength on the right (MD 36.0 N, 95% CI 25.0 to 47.1) and left (MD 17 N 95% CI 0.5 to 33.5), but low-certainty evidence of little or no effect on maximum force of hip flexors on the right (MD -9.0 N, 95% CI -22.4 to 4.4) or left (MD 6.0 N, 95% CI -6.6 to 18.6). This trial also provided low-certainty evidence of a slight decrease of aerobic capacity (MD -1.2 min, 95% CI -1.6 to 0.9). For participants with dermatomyositis and polymyositis (21 participants), we found very low-certainty evidence for slight increases in muscle strength as measured by dynamic strength of knee extensors on the right (MD 2.5 kg, 95% CI 1.8 to 3.3) and on the left (MD 2.7 kg, 95% CI 2.0 to 3.4) and no clear effect in isometric muscle strength of eight different muscles (MD 1.0, 95% CI -1.1 to 3.1). There was very low-certainty evidence that there may be an increase in aerobic capacity, as measured with time to exhaustion in an incremental cycle test (17.5 min, 95% CI 8.0 to 27.0) and power performed at VO max (maximal oxygen uptake) (18 W, 95% CI 15.0 to 21.0). For participants with mitochondrial myopathy (18 participants), we found very low-certainty evidence regarding shoulder muscle (MD -5.0 kg, 95% CI -14.7 to 4.7), pectoralis major muscle (MD 6.4 kg, 95% CI -2.9 to 15.7), and anterior arm muscle strength (MD 7.3 kg, 95% CI -2.9 to 17.5). We found very low-certainty evidence regarding aerobic capacity, as measured with mean time cycled (MD 23.7 min, 95% CI 2.6 to 44.8) and mean distance cycled until exhaustion (MD 9.7 km, 95% CI 1.5 to 17.9). One trial in myotonic dystrophy type 1 (35 participants) did not provide data on muscle strength or aerobic capacity following combined training. In this trial, muscle strength deteriorated in one person and one person had worse daytime sleepiness (very low-certainty evidence). For participants with FSHD (16 participants), we found very low-certainty evidence regarding muscle strength, aerobic capacity and VO peak; the results were very imprecise. Most trials reported no adverse events other than muscle soreness or joint complaints (low- to very low-certainty evidence).
AUTHORS' CONCLUSIONS
The evidence regarding strength training and aerobic exercise interventions remains uncertain. Evidence suggests that strength training alone may have little or no effect, and that aerobic exercise training alone may lead to a possible improvement in aerobic capacity, but only for participants with FSHD. For combined aerobic exercise and strength training, there may be slight increases in muscle strength and aerobic capacity for people with dermatomyositis and polymyositis, and a slight decrease in aerobic capacity and increase in muscle strength for people with juvenile dermatomyositis. More research with robust methodology and greater numbers of participants is still required.

Meta-Analysis Review
BACKGROUND
Rheumatoid arthritis is an inflammatory polyarthritis that frequently affects the hands and wrists. Hand exercises are prescribed to improve mobility and strength, and thereby hand function.
OBJECTIVES
To determine the benefits and harms of hand exercise in adults with rheumatoid arthritis.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library), MEDLINE, Embase, CINAHL, AMED, Physiotherapy Evidence Database (PEDro), OTseeker, Web of Science, ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) up to July 2017.
SELECTION CRITERIA
We considered all randomised or quasi-randomised controlled trials that compared hand exercise with any non-exercise therapy.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures as outlined by the Cochrane Musculoskeletal Group.
MAIN RESULTS
We included seven studies involving 841 people (aged 20 to 94 years) in the review. Most studies used validated diagnostic criteria and involved home programmes.Very low-quality evidence (due to risk of bias and imprecision) from one study indicated uncertainty about whether exercise improves hand function in the short term (< 3 months). On a 0 to 80 points hand function test (higher scores mean better function), the exercise group (n = 11) scored 76.1 points and control group (n = 13) scored 75 points.Moderate-quality evidence (due to risk of bias) from one study indicated that exercise compared to usual care probably slightly improves hand function (mean difference (MD) 4.5, 95% confidence interval (CI) 1.58 to 7.42; n = 449) in the medium term (3 to 11 months) and in the long term (12 months or beyond) (MD 4.3, 95% CI 0.86 to 7.74; n = 438). The absolute change on a 0-to-100 hand function scale (higher scores mean better function) and number needed to treat for an additional beneficial outcome (NNTB) were 5% (95% CI 2% to 7%); 8 (95% CI 5 to 20) and 4% (95% CI 1% to 8%); 9 (95% CI 6 to 27), respectively. A 4% to 5% improvement indicates a minimal clinical benefit.Very low-quality evidence (due to risk of bias and imprecision) from two studies indicated uncertainty about whether exercise compared to no treatment improved pain (MD -27.98, 95% CI -48.93 to -7.03; n = 124) in the short term. The absolute change on a 0-to-100-millimetre scale (higher scores mean more pain) was -28% (95% CI -49% to -7%) and NNTB 2 (95% CI 2 to 11).Moderate-quality evidence (due to risk of bias) from one study indicated that there is probably little or no difference between exercise and usual care on pain in the medium (MD -2.8, 95% CI - 6.96 to 1.36; n = 445) and long term (MD -3.7, 95% CI -8.1 to 0.7; n = 437). On a 0-to-100 scale, the absolute changes were -3% (95% CI -7% to 2%) and -4% (95% CI -8% to 1%), respectively.Very low-quality evidence (due to risk of bias and imprecision) from three studies (n = 141) indicated uncertainty about whether exercise compared to no treatment improved grip strength in the short term. The standardised mean difference for the left hand was 0.44 (95% CI 0.11 to 0.78), re-expressed as 3.5 kg (95% CI 0.87 to 6.1); and for the right hand 0.46 (95% CI 0.13 to 0.8), re-expressed as 4 kg (95% CI 1.13 to 7).High-quality evidence from one study showed that exercise compared to usual care has little or no benefit on mean grip strength (in kg) of both hands in the medium term (MD 1.4, 95% CI -0.27 to 3.07; n = 400), relative change 11% (95% CI -2% to 13%); and in the long term (MD 1.2, 95% CI -0.62 to 3.02; n = 355), relative change 9% (95% CI -5% to 23%).Very low-quality evidence (due to risk of bias and imprecision) from two studies (n = 120) indicated uncertainty about whether exercise compared to no treatment improved pinch strength (in kg) in the short term. The MD and relative change for the left and right hands were 0.51 (95% CI 0.13 to 0.9) and 44% (95% CI 11% to 78%); and 0.82 (95% CI 0.43 to 1.21) and 68% (95% CI 36% to 101%).High-quality evidence from one study showed that exercise compared to usual care has little or no benefit on mean pinch strength of both hands in the medium (MD 0.3, 95% CI -0.14 to 0.74; n = 396) and long term (MD 0.4, 95% CI -0.08 to 0.88; n = 351). The relative changes were 8% (95% CI -4% to 19%) and 10% (95% CI -2% to 22%).No study evaluated the American College of Rheumatology 50 criteria.Moderate-quality evidence (due to risk of bias) from one study indicated that people who also received exercise with strategies for adherence were probably more adherent than those who received routine care alone in the medium term (risk ratio 1.31, 95% CI 1.15 to 1.48; n = 438) and NNTB 6 (95% CI 4 to 10). In the long term, the risk ratio was 1.09 (95% CI 0.93 to 1.28; n = 422).Moderate-quality evidence (due to risk of bias) from one study (n = 246) indicated no adverse events with exercising. The other six studies did not report adverse events.
AUTHORS' CONCLUSIONS
It is uncertain whether exercise improves hand function or pain in the short term. It probably slightly improves function but has little or no difference on pain in the medium and long term. It is uncertain whether exercise improves grip and pinch strength in the short term, and probably has little or no difference in the medium and long term. The ACR50 response is unknown. People who received exercise with adherence strategies were probably more adherent in the medium term than who did not receive exercise, but with little or no difference in the long term. Hand exercise probably does not lead to adverse events. Future research should consider hand and wrist function as their primary outcome, describe exercise following the TIDieR guidelines, and evaluate behavioural strategies.

Meta-Analysis Review
BACKGROUND
Therapeutic taping may be a useful modality in relieving pain, improving strength, and restoring the function of patients with De Quervain's Disease (DQD). Evidence on the effectiveness of therapeutic taping for DQD patients in mitigating its clinical signs and symptoms is not established. However, reviews report Kinesio Taping effects on musculoskeletal pains not specific to DQD.
METHODS
The study followed the guideline statement of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Two researchers (RD and SN) searched the electronic databases and hand-searched for relevant journals. The relevant articles were selected using keywords found in titles and abstracts and, consequently, full-text manuscripts. A third researcher (VCDIII) resolved the disagreements between the two researchers. They used Review Manager 5.4 for risk of bias assessment and meta-analysis. Data were pooled to determine the therapeutic taping's overall effect. Heterogeneity was assessed by Higgin's (I) statistic. The random-effects model was used if heterogeneity was high (>60%). The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Approach determined the certainty of evidence.
RESULTS
Seven high-risk of bias clinical-controlled trials comprising 241 participants were included in the meta-analysis. The reported outcome measures were the Visual Analogue Scale (VAS) for pain, Patient-Rated Wrist/Hand Examination for Function and Power, and precision grip strength using a hand-held dynamometer and pinch gauge. Therapeutic taping did not improve the pain, power grip, grip strength, and function of participants with DQD (p > 0.05). Therapeutic taping compared to other physical therapy interventions did not reduce the VAS scores of 241 participants with DQD [SMD (95% CI) = -1.08 (-2.55,0.39), p = 0.15]. Kinesio taping with low-level laser therapy compared to ultrasound and exercise did not improve the function of 60 participants with DQD [SMD (95% CI) = 0.56 (-4.71,3.60), p = 0.79]. Therapeutic taping compared to ultrasound and Mulligan Pain Releasing Phenomenon did not improve the power grip strength of 50 participants with DQD [SMD (95% CI) = 1.24 (-0.83,3.31), p = 0.24]. Therapeutic taping was not better than phonophoresis in improving the precision grip strength of 50 participants with DQD [SMD (95% CI) = 0.43 (-1.95,2.80), p = 0.72].
CONCLUSIONS
There is insufficient evidence to recommend the use of therapeutic taping in treating patients with DQD. Therapeutic taping was no better than other treatment modalities in mitigating the clinical signs and symptoms of DQD (p > 0.05). Therapeutic taping did not affect wrist pain, handgrip, pincer strength, and function of participants with DQD (p > 0.05).

Meta-Analysis
OBJECTIVES
We aimed (1) to estimate the short-term effect (postintervention period) of neurodynamic techniques on pain, symptom severity, functional status, electrophysiological status, grip strength, and pinch strength in people with carpal tunnel syndrome (CTS); and (2) to estimate the effect of neurodynamic techniques compared to other physical therapy modalities and surgical interventions.
DESIGN
Intervention systematic review with meta-analysis.
LITERATURE SEARCH
We searched the MEDLINE, Cochrane Database of Systematic Reviews, Web of Science, Physiotherapy Evidence Database, and Scopus databases from their inception to September 2020.
STUDY SELECTION CRITERIA
We included randomized controlled trials reporting the effect of neurodynamic techniques on pain, symptom severity, function, distal motor latency, grip strength, and pinch strength in people with CTS.
DATA SYNTHESIS
Using the DerSimonian-Laird method, we estimated pooled standardized mean differences (SMDs) and 95% confidence intervals (CIs). We used the Grading of Recommendations Assessment, Development and Evaluation approach to judge the certainty of the evidence of each pairwise comparison.
RESULTS
There were 22 trials included (n = 1203 people with CTS; mean age, 26.0 to 57.9 years; mean symptom duration, 4.1 to 62.8 months). There was very low-certainty evidence of neurodynamic techniques improving pain (SMD, -0.54; 95% CI: -0.95, -0.13) and function (SMD, -0.35; 95% CI: -0.61, -0.09). There was no significant effect on symptom severity (very low certainty), distal motor latency (very low certainty), and grip and pinch strength (low certainty).
CONCLUSION
Neurodynamic techniques were effective for improving pain and function in people with CTS, albeit with very low-certainty evidence. .

British Journal of Sports Medicine May 2021To evaluate the effectiveness of exercise compared with other conservative interventions in the management of lateral elbow tendinopathy (LET) on pain and function. (Meta-Analysis)
Meta-Analysis
Exercise interventions in lateral elbow tendinopathy have better outcomes than passive interventions, but the effects are small: a systematic review and meta-analysis of 2123 subjects in 30 trials.
OBJECTIVE
To evaluate the effectiveness of exercise compared with other conservative interventions in the management of lateral elbow tendinopathy (LET) on pain and function.
DESIGN
Systematic review and meta-analysis.
METHODS
We used the Cochrane risk-of-bias tool 2 for randomised controlled trials (RCTs) to assess risk of bias and the Grading of Recommendations Assessment, Development and Evaluation methodology to grade the certainty of evidence. Self-perceived improvement, pain intensity, pain-free grip strength (PFGS) and elbow disability were used as primary outcome measures.
ELIGIBILITY CRITERIA
RCTs assessing the effectiveness of exercise alone or as an additive intervention compared with passive interventions, wait-and-see or injections in patients with LET.
RESULTS
30 RCTs (2123 participants, 5 comparator interventions) were identified. Exercise outperformed (low certainty) corticosteroid injections in all outcomes at all time points except short-term pain reduction. Clinically significant differences were found in PFGS at short-term (mean difference (MD): 12.15, (95% CI) 1.69 to 22.6), mid-term (MD: 22.45, 95% CI 3.63 to 41.3) and long-term follow-up (MD: 18, 95% CI 11.17 to 24.84). Statistically significant differences (very low certainty) for exercise compared with wait-and-see were found only in self-perceived improvement at short-term, pain reduction and elbow disability at short-term and long-term follow-up. Substantial heterogeneity in descriptions of equipment, load, duration and frequency of exercise programmes were evident.
CONCLUSIONS
Low and very low certainty evidence suggests exercise is effective compared with passive interventions with or without invasive treatment in LET, but the effect is small.

Review
Opposition is an essential function of the human thumb to enable fine pinch and grip strength. Loss of opposition can be caused by both congenital and acquired pathology resulting in significant disability. This systematic review aims to compare the different techniques available to restore opposition. A systematic review of opponensplasty techniques was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines using PubMed, Embase, Medline, and Web of Science. Studies published in English before April 2021 and that reported on original outcomes of opponensplasty techniques used in the context of neurologic dysfunction were eligible for inclusion. A total of 641 articles were included, of which 42 texts were eligible for inclusion with a total cohort of 873 patients. The most commonly used transfers were palmaris longus (PL), extensor indicis proprius (EIP), and flexor digitorum superficialis (FDS). These transfers all demonstrated an improvement in range of motion, pinch strength, and Kapandji scores. Complication rates of 19% and 12% were reported with FDS and EIP transfers, respectively, predominantly related to donor site morbidity. A complication rate of 6% was observed with PL transfers, which was most commonly related to bowstringing. Heterogeneity of outcomes precluded a direct statistical comparison. There is significant heterogeneity in the literature reporting on opponensplasty techniques. There is limited capacity of direct comparison; however, FDS and EIP appear to demonstrate better functional outcomes, at the cost of higher complication rates. Each technique has specific complications and advantages and importance in patient counseling and discussion. Further prospective comparative studies are warranted.

Review
AIMS
We performed a systematic review of the current literature regarding the outcomes of unconstrained metacarpophalangeal joint (MCPJ) arthroplasty.
MATERIALS AND METHODS
We initially identified 1305 studies, and 406 were found to be duplicates. After exclusion criteria were applied, seven studies were included. Outcomes extracted included pre- and post-operative pain visual analogue scores, range of movement (ROM), strength of pinch and grip, satisfaction and patient reported outcome measures (PROMs). Clinical and radiological complications were recorded. The results are presented in three groups based on the design of the arthroplasty and the aetiology (pyrocarbon-osteoarthritis (pyro-OA), pyrocarbon-inflammatory arthritis (pyro-IA), metal-on-polyethylene (MoP)).
RESULTS
Results show that pyrocarbon implants provide an 85% reduction in pain, 144% increase of pinch grip and 13° improvements in ROM for both OA and IA combined. Patients receiving MoP arthroplasties had a reduction in pinch strength. Satisfaction rates were 91% and 92% for pyrocarbon-OA and pyrocarbon-IA groups, respectively. There were nine failures in 87 joints (10.3%) over a mean follow-up of 5.5 years (1.0 to 14.3) for pyro-OA. There were 18 failures in 149 joints (12.1%) over a mean period of 6.6 years (1.0 to 16.0) for pyro-IA. Meta-analysis was not possible due to the heterogeneity of the studies and the limited presentation of data.
CONCLUSION
We would recommend prospective data collection for small joint arthroplasties of the hand consisting of PROMs that would allow clinicians to come to stronger conclusions about the impact on function of replacing the MCPJs. A national joint registry may be the best way to achieve this. Cite this article: Bone Joint J 2017;99-B:100-6.

International Journal of Dental Hygiene Aug 2023The objective of this review was to examine the impact of instrument designs on pinch force generation during scaling by dental professionals. (Review)
Review
OBJECTIVE
The objective of this review was to examine the impact of instrument designs on pinch force generation during scaling by dental professionals.
METHODS
Three databases were utilized from September 2019 to November 2021 in addition to hand-searching specific journals and reference lists. Research articles that examined pinch force generation in dental professionals during scaling with manual instruments only were included. Bias was assessed in the individual articles.
RESULTS
Six research articles were included with sample populations that varied from 12 to 24 participants. Four articles evaluated instrument designs in relation to pinch force generation during scaling by dental professionals. Two articles evaluated the clinicians' experience levels and the impact on pinch force generation. Results of three articles revealed instruments with large diameters and low weights produced the least amount of pinch force (p < 0.05). Additionally, two articles found instruments with a round, tapered shape produced less pinch force and instrument handles made of silicone produced higher pinch strength post-scaling (p < 0.05). One study indicated instrument designs associated with modified scaling techniques may reduce thumb and index finger pinch force (p < 0.05).
CONCLUSION
The findings from this review indicate weak evidence for instrument choices to reduce pinch force during scaling. Dental professionals should consider lightweight and large diameter instruments for manual scaling. Clinicians may also want to consider round, tapered handles and instrument designs with modified scaling techniques. This systematic review further identified the need for clinical research studies with rigorous research designs that examine the ergonomic impacts of instrument designs.

PURPOSE
The first carpometacarpal (CMC) joint is a frequent location of osteoarthritis in the hand. The denervation of the first CMC joint has gained traction as a viable treatment for CMC arthritis. This study reviewed literature on CMC denervation for first CMC arthritis.
METHODS
A systematic review of papers and abstracts was conducted. The preferred reporting items for systematic reviews and meta-analyses guidelines were followed. Articles including the results of CMC denervation were included. We compiled data on patient demographics, preoperative testing, intraoperative technique, and postoperative outcomes. Anatomic literature was also reviewed to assess agreement on the innervation of the first CMC joint.
RESULTS
Six anatomic studies and 9 clinical studies were included in this systematic review. Pinch strength, grip strength, and Kapandji scores increased on average in patients. Pain relief was noted on average in patients in 5 studies that reported pain outcomes. In studies that reported postoperative complications, the most frequent complications were radial paresthesias, hypoesthesia dorsal and/or distal to the surgical site, and wound infection.
CONCLUSIONS
The innervation of the CMC joint is controversial. This is reflected in clinical practice, wherein varied surgical approaches are used. Carpometacarpal denervation shows promise as an option to treat patients with CMC arthritis without joint instability, but its results vary. Additional clinical studies with longer-term follow-up and control groups are necessary to better determine its longevity and efficacy.

Meta-Analysis
BACKGROUND AND OBJECTIVE
The efficacy and safety of edaravone for the treatment of amyotrophic lateral sclerosis (ALS) remain unclear. The aim of this meta-analysis was to provide evidence-based medical guidance and advice for the clinical application of edaravone in the treatment of ALS.
METHODS
PubMed, Embase, Chinese Biomedical Literature Database (CBM), Cochrane Library and Web of Science were searched through 09 March 2022 for randomized controlled trials (RCTs) on the safety and efficacy of edaravone versus placebo during follow-up of patients with ALS. A summary of the outcome measures with GRADE was performed. This study was registered on PROSPERO (ID: CRD 42022319997).
RESULTS
Five RCTs with a total of 566 participants were included, and there was a significant difference (mean difference [MD] 1.33, 95% confidence interval [CI] 0.33-2.34; p = 0.009) in the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score between the treatment and placebo groups. The edaravone group had an increased grip strength (MD 0.26, 95% CI 0.03-0.49; p = 0.03) and modified Norris Scale score (MD 2.81, 95% CI 1.18-4.43; p = 0.0007). However, there were no significant differences between groups for the change in forced vital capacity (FVC)% (MD 0.55, 95% CI - 3.15 to 4.24; p = 0.77), pinch strength (MD 0.05, 95% CI - 0.05 to 0.16; p = 0.33) or Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-40) score (MD - 4.76, 95% CI - 9.56 to 0.03; p = 0.05). The incidence of adverse events (AEs) (risk ratio [RR] 0.09, 95% CI 0.93-1.05; p = 0.65), serious adverse events (SAEs) (RR 0.72, 95% CI 0.52-1.00; p = 0.05) and the number of deaths (risk difference [RD] 0.00, 95% CI - 0.02 to 0.03; p = 0.83) were not statistically different from the placebo group. The quality of evidence was low only for SAEs, and the remaining outcome measures were of moderate quality.
CONCLUSIONS
Compared with placebo, edaravone may provide potential clinical benefits in the treatment of ALS and may not increase the number of AEs and deaths. However, due to the low-quality evidence of the included studies and the small sample size, more high-quality and high-standard research evidence is needed to confirm these results.
