BACKGROUND
Adopting a physically active lifestyle is advocated as a strategy to prevent loss of physical independence and support healthy aging. This study aimed to evaluate the physical independence and related factors among older adults.
MATERIALS AND METHODS
This systematic review and meta-analysis was conducted through electronic databases such as Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database from the earliest to 1 April 2022. Two researchers independently extracted information from the studies and evaluated the quality of the studies. The analysis was conducted using CMA program version 3, and each study's importance was determined based on its inverse variance.
RESULTS
Five thousand seven hundred thirty-three older adults participated in this review in six studies. All evaluated studies had high quality. The mean score of physical independence in older adults was 20.07 (SE=0.76) out of 24 (95% CI: 18.58-21.56; =98.573%; <0.001). Physical activity is very important for physical independence and reduces the risk of physical dependence in older adults. Other factors, such as sex, BMI, age, abnormal performance, timed performance, sufficiently active, muscle function, handgrip strength, lower extremity function, lower body strength, maximal isometric knee extension power, lung function, aerobic endurance, sedentary time, agility, and the prevalence of arthritis, had a significant relationship with physical independence in older adults.
CONCLUSION
Older adults demonstrate favourable levels of physical independence. Notably, physical activity emerges as a significant determinant positively associated with such independence. Thus, policymakers and administrators are encouraged to strategize the creation of conducive environments for walking and exercise among older adults.

Review
INTRODUCTION
Although resistance training is frequently prescribed for people with haemophilia (PWH), no previous meta-analyses have quantified the effect of this intervention on muscle strength, nor the implications of the intervention's modality and duration.
AIM
(1) To determine the effects of resistance training on muscle strength in adults with haemophilia; (2) To determine the most effective duration and modality among the exercise protocols.
METHODS
A systematic search from inception until 28 November 2023 was conducted in PubMed, Embase, Web of Science, CENTRAL and CINAHL databases. We included randomised controlled trials or before-after studies that involved resistance training without other physiotherapy co-interventions. Study selection, data extraction and risk of bias assessment were independently performed by two reviewers. Disagreements were resolved in consultation with a third author. The level of evidence was determined according to the GRADE methodology.
RESULTS
Seven studies were included. Measurements of knee extensor strength and elbow extensor strength were included in the meta-analysis. Subgroup analysis showed significant effects for both elastic resistance protocols (SMD: 0.54; 95% CI: 0.02-1.07) and conventional training (isometric and weight-based equipment) (SMD: 0.88; 95% CI: 0.50-1.25), demonstrating small and moderate effect sizes respectively. Additionally, both protocols of duration 5-7 weeks (SMD: 1.16, 95% CI: 0.63-1.69) as well as those of duration ≥8 weeks (SMD: 0.57, 95% CI: 0.20-0.94) showed a significant difference.
CONCLUSION
Resistance training is effective in improving muscle strength of the knee and elbow extensors in PWH. Both elastic resistance and conventional training show benefits.

Review
Steroids stand for a class of hormones (natural and synthetic) known to be helpful for a number of disorders. Despite the aforementioned beneficial effects of using these hormones, anabolic-androgenic steroids (AAS) are also widely abused in a non-therapeutic manner for muscle-building and strength-increasing properties that may lead to genotoxicity in different tissues. The present study aims to understand whether genotoxicity may be a suitable biomarker for AAS exposure in vivo in both experimental animal and human studies. All studies published in PubMed/Medline, Scopus, and Web of Science electronic databases that presented data on DNA damage caused by AAS were analyzed. A total of 15 articles were included in this study, and after thoroughly reviewing the studies, a total of 8 articles were classified as Strong, 6 were classified as Moderate, and only 1 was classified as Weak, totaling 14 studies being considered either Strong or Moderate. This classification makes it possible to consider the present findings as reliable. The meta-analysis data revealed a statistically significant difference in Wistar rat testis cells with AAS compared to control for tail length and % tail DNA (p < 0.001), so that the selected articles were considered homogeneous and the I of 0% indicated low heterogeneity. In summary, genotoxicity can be considered a suitable biomarker for monitoring AAS exposure as a result of DNA breakage and oxidative DNA damage.

Review
BACKGROUND
Upper limb impairments are among the most common consequences following a stroke. Recently, robot-assisted therapy (RT) and virtual reality (VR) have been used to improve upper limb function in stroke survivors.
OBJECTIVES
This review aims to investigate the effects of combined RT and VR on upper limb function in stroke survivors and to provide recommendations for researchers and clinicians in the medical field.
METHODS
We searched PubMed, SCOPUS, REHABDATA, PEDro, EMBASE, and Web of Science from inception to March 28, 2024. Randomized controlled trials (RCTs) involving stroke survivors that compared combined RT and VR interventions with either passive (i.e., sham, rest) or active (i.e., traditional therapy, VR, RT) interventions and assessed outcomes related to upper limb function (e.g., strength, muscle tone, or overall function) were included. The Cochrane Collaboration tool was used to evaluate the methodological quality of the included studies.
RESULTS
Six studies were included in this review. In total, 201 patients with stroke (mean age 57.84 years) were involved in this review. Four studies were considered 'high quality', while two were considered as 'moderate quality' on the Cochrane Collaboration tool. The findings showed inconsistent results for the effects of combined RT and VR interventions on upper limb function poststroke.
CONCLUSION
In conclusion, there are potential effects of combined RT and VR interventions on improving upper limb function, but further research is needed to confirm these findings, understand the underlying mechanisms, and assess the consistency and generalizability of the results.

Whole-body vibration (WBV) training has been employed alongside conventional exercise like resistance training to enhance skeletal muscle strength and performance. This systematic review examines the evidence regarding the effect of WBV on muscle activity, strength, and performance in healthy individuals. The Academic Search Ultimate, CINAHL, Cochrane CENTRAL, PubMed, ProQuest One Academic and SCOPUS databases were searched from 1990 to April 2023 to retrieve relevant studies. Methodological quality was assessed using the Modified Downs and Black checklist, while the level of evidence was evaluated through the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. Even though the quality of the included studies was moderate to high, the level of evidence was very low owing to serious concerns with three or more GRADE domains (risk of bias, inconsistency, indirectness, imprecision, and publication bias) for each outcome of interest across studies. The review suggests that in WBV training, using moderate to high vibration frequencies (25-40 Hz) and high magnitudes (3-6 mm) can enhance muscle activation and strength in pelvis and lower limb muscles. However, findings regarding WBV effect on muscle performance measures were inconsistent. Future research with robust methodology is necessary in this area to validate and support these findings.

Review
Lower limb impairments are common consequences of stroke. Robotics and virtual reality (VR) play crucial roles in improving lower limb function post-stroke. This review aims to assess the effects of combined robot and VR interventions on lower limb functional ability poststroke and to provide recommendations for future studies in the rehabilitation field. PubMed, SCOPUS, CINAHL, MEDLINE, EMBASE, and Web of Science were searched from inception to March 1, 2024. Randomized controlled trials (RCTs) involving patients with a stroke, administering combined robot and VR compared with passive (i.e., rest) or active (any intervention), and including at least one outcome evaluating lower limb function (i.e., balance, gait, mobility, muscle tone, muscle strength, range of motion) or activities of daily living were selected. The Cochrane Collaboration tool was employed to evaluate the risk of bias in the included studies. Nine studies met the eligibility criteria. In total, 364 stroke survivors (Mean age 55.62 years) were involved in this review. According to the Cochrane Collaboration tool, five studies were classified as "high quality," "moderate quality" (n=3), and "low quality" (n=1). There are mixed findings on the effects of combined robot and VR on lower limb functional ability in stroke survivors. The evidence for the effects of combined robot and VR on lower limb functional ability post-stroke is promising. Further trials with long-term follow-up are strongly warranted to understand the immediate and long-term effect of combined robot and VR intervention on various lower limb impairments and to define the optimal treatment protocols.

Review
BACKGROUND
Though popular after joint replacement surgery, progressive resistance training (PRT) has controversial safety and efficacy claims. Therefore, PRT's effect on early postoperative muscle strength and functional capacity following total knee arthroplasty (TKA) must be thoroughly investigated. Between May 12, 2020, and February 12, 2002, the Cochrane Library, Web of Science, and Medline databases containing pertinent literature were thoroughly reviewed for this investigation.
METHODS
Out of 704 studies, 9 (TKA) met inclusion criteria for meta-analysis, involving 1021 adult patients. The analysis encompassed various post-TKA indicators at 1, 3, and 12 months, including the 6-Minute Walk Test (6-WMT), Stair Climbing Performance (SCP), leg extension strength, Timed Up and Go Test (TUG), and Sit-to-Stand (ST) repetitions.
RESULTS
In TKA patients, 6-WMT within 1 month (95 % CI = -0.41, 1.53), 3 months (95 % CI = -0.27, 0.76), and 12 months (95 % CI = -0.29, 0.66) did not show any significant differences. There were no discernible changes in ST at various time intervals, SCP, leg extension strength, and TUG at 1 month (95 % CI = -1.75, 0.77), 3 months (95 % CI = -0.48, 0.33), and 12 months (95 % CI = -0.44, 0.35). There was no statistical difference in the incidence of adverse events between the two groups (95 % CI = -0.01, 0.10).
CONCLUSION
Early post-TKA PRT demonstrated no significant differences compared to Standard Rehabilitation (SR) regarding functional capacity, muscle strength recovery, and adverse event incidence. Therefore, PRT is a feasible option for promoting swift recovery post-total knee arthroplasty.

Delayed postoperative neurological deficits from scoliosis correction: a case series and systematic review on clinical characteristics, treatment, prognosis, and recovery.
OBJECTIVE
This study was designed to investigate the clinical features, treatment modalities, and risk factors influencing neurological recovery in patients who underwent scoliosis correction with delayed postoperative neurological deficit (DPND).
METHODS
Three patients with DPND were identified from 2 central databases for descriptive analysis. Furthermore, all DPND cases were retrieved from the PubMed and Embase databases. Neurological function recovery was categorized into complete and incomplete recovery groups based on the American Spinal Injury Association (ASIA) impairment scale.
RESULTS
Two patients were classified as type 3, and one was classified as type 2 based on the MRI spinal cord classification. Intraoperative neurophysiological monitoring (IONM) was consistently negative throughout the corrective procedure, and intraoperative wake-up tests were normal. The average time to DPND development was 11.8 h (range, 4-18 h), and all three patients achieved complete recovery of neurological function after undergoing revision surgery. A total of 14 articles involving 31 patients were included in the literature review. The mean time to onset of DPND was found to be 25.2 h, and 85.3% (29/34) of patients experienced DPND within the first 48 h postoperatively, with the most common initial symptoms being decreased muscle strength and sensation (26 patients, 83.9%). Regarding neurological function recovery, 14 patients were able to reach ASIA grade E, while 14 patients were not able to reach ASIA grade E. Univariate analysis revealed that preoperative diagnosis (p = 0.004), operative duration (p = 0.017), intraoperative osteotomy method (p = 0.033), level of neurological deficit (p = 0.037) and deficit source (p = 0.0358) were significantly associated with neurological outcomes. Furthermore, multivariate regression analysis indicated a strong correlation between preoperative diagnosis (p = 0.003, OR, 68.633; 95% CI 4.299-1095.657) and neurological prognosis.
CONCLUSION
Our findings indicate that spinal cord ischemic injury was a significant factor for patients experiencing DPND and distraction after corrective surgery may be a predisposing factor for spinal cord ischemia. Additionally, it is important to consider the possibility of DPND when limb numbness and decreased muscle strength occur within 48 h after corrective scoliosis surgery. Moreover, emergency surgical intervention is highly recommended for DPND caused by mechanical compression factors with a promising prognosis for neurological function, emphasizing the importance of taking into account preoperative orthopedic diagnoses when evaluating the potential for neurological recovery.

BACKGROUND
Biomechanical alterations in patients with low back pain (LBP), as reduced range of motion or strength, do not appear to be exclusively related to the trunk. Thus, studies have investigated biomechanical changes in the hip, due to the proximity of this joint to the low back region. However, the relationship between hip biomechanical changes in patients with LBP is still controversial and needs to be summarized. Therefore, the aim of this study was to systematically review observational studies that used biomechanical assessments in patients with non-specific LBP.
METHODS
The search for observational studies that evaluated hip biomechanical variables (i.e., range of motion, kinematic, strength, and electromyography) in adults with non-specific acute, subacute, and chronic LBP was performed in the PubMed, Embase, Cinahl and Sportdiscus databases on February 22, 2024. Four blocks of descriptors were used: 1) type of study, 2) LBP, 3) hip and 4) biomechanical assessment. Two independent assessors selected eligible studies and extracted the following data: author, year of publication, country, study objective, participant characteristics, outcomes, and results. The methodological quality of the studies was assessed using the Epidemiological Appraisal Instrument and classified as low, moderate, and high. Due to the heterogeneity of the biomechanical assessment and, consequently, of the results among eligible studies, a descriptive analysis was performed.
RESULTS
The search strategy returned 338 articles of which 54 were included: nine articles evaluating range of motion, 16 evaluating kinematic, four strength, seven electromyography and 18 evaluating more than one outcome. The studies presented moderate and high methodological quality. Patients with LBP, regardless of symptoms, showed a significant reduction in hip range of motion, especially hip internal rotation, reduction in the time to perform functional activities such as sit-to-stance-to-sit, sit-to-stand or walking, greater activation of the hamstrings and gluteus maximus muscles and weakness of the hip abductor and extensor muscles during specific tests and functional activities compared to healthy individuals.
CONCLUSION
Patients with LBP present changes in range of motion, task execution, activation, and hip muscle strength when compared to healthy individuals. Therefore, clinicians must pay greater attention to the assessment and management of the hip during the treatment of these patients.

Meta-Analysis Review
INTRODUCTION
To date, it is unknown whether respiratory training interventions can benefit Long COVID-19 patients. The main objective was to analyze the effects of respiratory training on patients with Long COVID-19, concretely on respiratory muscle strength, lung function, dyspnea, and functional capacity.
METHODS
We performed a systematic review following PRISMA statement using PubMed, Scopus, and PEDro (last search November 2023). The risk of bias was assessed using the Cochrane tool. We included randomized controlled trials testing the effect of respiratory training interventions in Long COVID-19 patients versus no intervention, control, or placebo intervention. The data was pooled, and a meta-analysis was complete.
RESULTS
We selected 7 studies, which included 572 patients. Meta-analysis results show significant differences in favor of respiratory training in respiratory muscle strength (MD = 13.71; 95% CI = 5.41; 22; = 0.001), dyspnea (SDM = 1.39; 95% CI = 0.33; 2.46; = 0.01) and functional capacity (SDM = 0.90; 95% CI = 0.37; 1.43; = 0.0009), but not in lung function (MD = 0.28; 95%CI = -0.27; 0.83; = 0.32).
CONCLUSION
The results of this systematic review with meta-analysis suggest that respiratory training improves respiratory muscle strength and functional capacity in Long COVID-19 patients, as well as dyspnea if combined with therapeutic exercise. However, respiratory training does not improve lung function in these patients.
