Effects of Combined Upper and Lower Limb Plyometric Training Interventions on Physical Fitness in Athletes: A Systematic Review with Meta-Analysis

Objective: We aimed to meta-analyze the effects of combined upper and lower limb plyometric training (ULLPT) on physical fitness attributes in athletes. Methods: A systematic literature search was conducted in Web of Science, SPORTDiscus, PubMed, and SCOPUS, for up to 13 August 2022. Controlled studies with baseline and follow-up measures were included if they examined the effects of ULLPT on at least one measure of physical fitness indices in athletes. A random effects meta-analysis was performed using the Comprehensive Meta-Analysis software. Results: Fifteen moderate-to-high-quality studies with 523 participants aged 12−22.4 years were included in the analyses. Small to large (ES = 0.42−1.66; p = 0.004 to <0.001) effects were noted for upper and lower body muscle power, linear sprint speed, upper and lower body muscle strength, agility, and flexibility, while no significant effects on static and dynamic balance were noted (ES = 0.44−0.10; all p > 0.05). Athletes’ sex, age, and training program variables had no modulator role on the effects of ULLPT in available data sets. Conclusions: ULLPT induces distinct neuro-muscular adaptations in the upper and lower body musculature and is an efficient method for enhancing athletes’ physical fitness.

Auditory Stimulation Improves Gait and Posture in Cerebral Palsy: A Systematic Review with Between- and Within-Group Meta-Analysis

The past decade has seen an increased interest in the implementation of auditory stimulation (AStim) for managing gait and postural deficits in people with cerebral palsy. Although existing reviews report beneficial effects of AStim on the spatiotemporal and kinematic parameters of gait, there are still numerous limitations that need to be addressed to correctly interpret these results. For instance, existing reviews have failed to characterize the effects of AStim by conducting separate between and within-group meta-analyses, these reviews have not evaluated the influence of AStim on postural outcomes, and nor have included several high-quality existing trials. In this study, we conducted between- and within-group meta-analyses to establish a state of evidence for the influence of AStim on gait and postural outcomes in people with cerebral palsy. We searched the literature according to PRISMA-P guidelines across 10 databases. Of 1414 records, 14 studies, including a total of 325 people with cerebral palsy, met the inclusion criterion. We report a significant enhancement in gait speed, stride length, cadence, and gross motor function (standing and walking) outcomes with AStim compared to conventional physiotherapy. The findings from this analysis reveal the beneficial influence of AStim on the spatiotemporal and kinematic parameters of gait and postural stability in people with cerebral palsy. Furthermore, we discuss the futurized implementation of smart wearables that can deliver person-centred AStim rehabilitation in people with cerebral palsy.

Jump rope training effects on health- and sport-related physical fitness in young participants: A systematic review with meta-analysis

The aim of this systematic review with meta-analysis was to assess the available body of published peer-reviewed articles related on the effects of jump rope training (JRT) compared with active/passive controls on health- and sport-related physical fitness outcomes. Searches were conducted in three databases, including studies that satisfied the following criteria: i) healthy participants; ii) a JRT programprogramme; iii) active or traditional control group; iv) at least one measure related to health- and sport-related physical fitness; v) multi-arm trials. The random-effects model was used for the meta-analyses. Twenty-one moderate-high quality (i.e., PEDro scale) studies were meta-analysed, involving 1,021 participants (male, 50.4%). Eighteen studies included participants with a mean age <18 years old. The duration of the JRT interventions ranged from 6 to 40 weeks. Meta-analyses revealed improvements (i.e., p = 0.048 to <0.001; ES = 0.23-1.19; I² = 0.0-76.9%) in resting heart rate, body mass index, fat mass, cardiorespiratory endurance, lower- and upper-body maximal strength, jumping, range of motion, and sprinting. No significant JRT effects were noted for systolic-diastolic blood pressure, waist-hip circumference, bone or lean mass, or muscle endurance. In conclusion, JRT, when compared to active and passive controls, provides a range of small-moderate benefits that span health- and sport-related physical fitness outcomes.

Is high intensity laser therapy more effective than other physical therapy modalities for treating knee osteoarthritis? A systematic review and network meta-analysis

Background

The use of physical therapy modalities, especially high intensity laser therapy (HILT), for individuals with knee osteoarthritis (KOA) is still controversial.

Objective

To compare the effects of HILT to other physical therapy modalities on symptoms and function in individuals with KOA.

Methods

Six databases (PubMed, Embase, Cochrane Library, Web of Science, EBSCO, and PEDro) were searched in March 2022. Included studies were randomized controlled trials involving HILT conducted on individuals with KOA. The end-trial weighted mean difference (WMD) and standard deviations (SD) with 95% confidence intervals (CI) were analyzed.

Results

Ten studies with 580 participants were obtained, of which nine were included in the final network meta-analysis. In terms of relieving pain, HILT demonstrated the highest probability of being among the most effective treatments, with surface under the cumulative ranking (SUCRA) = 100%, and compared to a control (placebo laser or exercise or a combination of both) on the visual analog scale (VAS) for pain it demonstrated significant benefits (WMD 1.66, 95% CI 1.48–1.84). For improving self-reported function, as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total scores, the HILT SUCRA value led with 98.9%. When individuals with KOA were treated by HILT, the improvement in stiffness was statistically significant (WMD 0.78, 95% CI 0.52–1.04) but the amount of improvement was smaller than the minimal clinically important difference (MCID).

Conclusion

The current evidence suggests that HILT may be more effective than other physical therapy modalities for improving pain and function in individuals with KOA. For improving stiffness, however, it may not be clinically effective.

Efficacy of low-level laser therapy on pain, disability, pressure pain threshold, and range of motion in patients with myofascial neck pain syndrome: a systematic review and meta-analysis of randomized controlled trials

Low-level laser therapy (LLLT) is one of recent modalities for treatment of myofascial neck pain (MNP). Several RCTs have been conducted on its effectiveness. The aim of this comprehensive meta-analysis was to evaluate the effectiveness of LLLT on MNP. Electronic databases were searched for identifying eligible studies comparing the effectiveness of LLLT using any wavelength with placebo or active control in myofascial neck pain up to June 2022. Data related to pain intensity, pain pressure threshold (PPT), range of motion (ROM), and disability was analyzed as a pooled estimate of mean difference or standard mean difference (SMD) with 95% confidence intervals (CIs) using random/fixed-effect model. Funnel plot and Egger's linear regression test were also conducted to examine the risk of publication bias. A total of 13 randomized controlled trials were included in this systematic review and meta-analysis. The data assessing laser effectiveness on different outcomes of 556 patients were considered for meta-analysis. Pooled results revealed that LLLT was significantly effective in pain reduction (MD =  - 1.29, 95% CI =  - 2.36; - 0.23, P < 0.001). Also, secondary outcomes including PPT (SMD of 2.63, 95% CI = 0.96; 4.30, P < 0.01) and right bending ROM (SMD of 3.44, 95% CI = 0.64; 6.24, P < 0.01) were improved, while disability (MD of - 7.83, 95% CI =  - 17.1; 0.08, P = 1.34) did not improve significantly after LLLT. Our meta-data revealed that LLLT may reduce myofascial neck pain and its related outcomes. LLLT is suggested to be used by clinicians along with other therapies such as manual and exercise therapy.

Effectiveness of motor control exercises versus other musculoskeletal therapies in patients with pelvic girdle pain of sacroiliac joint origin: A systematic review with meta-analysis of randomized controlled trials

BACKGROUND

Pelvic girdle pain represents a group of musculoskeletal pain disorders associated with the sacroiliac joint and/or the surrounding musculoskeletal and ligamentous structures. Its physical management is still a serious challenge as it has been considered the primary cause of low back pain.

OBJECTIVE

This review sought to determine the effectiveness of motor control exercises for two clinically relevant measures; i.e., pain and disability, on patients with pelvic girdle pain of sacroiliac joint origin.

METHODS

This review covered only randomized controlled studies. Online databases, such as PubMed, Embase, Scopus, and Cochrane Library, were searched from January 1, 1990, to December 31, 2019. PEDro scale was used to assess the methodological quality of included studies, while Review Manager was employed to synthesize data in view of meta-analysis. The PRISMA guidelines were applied for this review.

RESULTS

Twelve randomized controlled trials of moderate-to-high quality were included in this review. The studies involved 1407 patients with a mean age ranging from 25.5 to 42.1 years as well as intervention and follow-up durations from 1 week to 2 years. Motor control exercises alone for pelvic girdle pain of sacroiliac joint origin were not effective in terms of pain reduction (SMD = 0.29 [-0.64,1.22]) compared to control interventions whereas they were slightly effective in terms of disability reduction (SMD =-0.07 [-0.67, 0.53]) at short-term. The combination of motor control exercises with other musculoskeletal therapies, however, revealed to be more effective than control interventions in terms of pain reduction (SMD =-1.78 [-2.49, -1.07]; 95%CI) and lessened disability (SMD =-1.80 [-3.03, -0.56]; 95%CI) at short-term.

CONCLUSION

Motor control exercises alone were not found to be effective in reducing pain at short-term. However, their combination with other musculoskeletal therapies revealed a significant and clinically-relevant decrease in pain and disability at short-term, especially in peripartum period.

Effect of Plyometric Jump Training on Skeletal Muscle Hypertrophy in Healthy Individuals: A Systematic Review With Multilevel Meta-Analysis

Objective: To examine the effect of plyometric jump training on skeletal muscle hypertrophy in healthy individuals. Methods: A systematic literature search was conducted in the databases PubMed, SPORTDiscus, Web of Science, and Cochrane Library up to September 2021. Results: Fifteen studies met the inclusion criteria. The main overall finding (44 effect sizes across 15 clusters median = 2, range = 1-15 effects per cluster) indicated that plyometric jump training had small to moderate effects [standardised mean difference (SMD) = 0.47 (95% CIs = 0.23-0.71); p < 0.001] on skeletal muscle hypertrophy. Subgroup analyses for training experience revealed trivial to large effects in non-athletes [SMD = 0.55 (95% CIs = 0.18-0.93); p = 0.007] and trivial to moderate effects in athletes [SMD = 0.33 (95% CIs = 0.16-0.51); p = 0.001]. Regarding muscle groups, results showed moderate effects for the knee extensors [SMD = 0.72 (95% CIs = 0.66-0.78), p < 0.001] and equivocal effects for the plantar flexors [SMD = 0.65 (95% CIs = -0.25-1.55); p = 0.143]. As to the assessment methods of skeletal muscle hypertrophy, findings indicated trivial to small effects for prediction equations [SMD = 0.29 (95% CIs = 0.16-0.42); p < 0.001] and moderate-to-large effects for ultrasound imaging [SMD = 0.74 (95% CIs = 0.59-0.89); p < 0.001]. Meta-regression analysis indicated that the weekly session frequency moderates the effect of plyometric jump training on skeletal muscle hypertrophy, with a higher weekly session frequency inducing larger hypertrophic gains [β = 0.3233 (95% CIs = 0.2041-0.4425); p < 0.001]. We found no clear evidence that age, sex, total training period, single session duration, or the number of jumps per week moderate the effect of plyometric jump training on skeletal muscle hypertrophy [β = -0.0133 to 0.0433 (95% CIs = -0.0387 to 0.1215); p = 0.101-0.751]. Conclusion: Plyometric jump training can induce skeletal muscle hypertrophy, regardless of age and sex. There is evidence for relatively larger effects in non-athletes compared with athletes. Further, the weekly session frequency seems to moderate the effect of plyometric jump training on skeletal muscle hypertrophy, whereby more frequent weekly plyometric jump training sessions elicit larger hypertrophic adaptations.

Effects of dance therapy in women with breast cancer: A systematic review protocol

BACKGROUND

Cancer is an important public health problem with an increasing global incidence in the recent decades. Breast cancer has become the leading cause of death in women worldwide. Women suffering from breast cancer, as well as survivors, may experience some adverse effects of treatment-including cancer-related fatigue, sleep disorders, and pain-which may manifest alone or in combination with other symptoms. Non-pharmacological interventions, such as physical activity, have been associated with improvements in these adverse effects. This study aims to evaluate the effects of dance therapy in women with breast cancer.

METHODS

We will perform a systematic review according to the Cochrane methodology. An overall search strategy will be developed and adapted for PubMed, Virtual Health Library, PEDro, SciELO, SciVerse Scopus, Cochrane Library, and Web of Science using the descriptors "Dance therapy" or "Dancing" and "Breast neoplasms" or "Breast cancer." The size of the intervention effect (Z) will be calculated for each outcome included in this review. Outcomes will be pain, cancer-related fatigue, sleep disturbance, body image and depression in women with breast cancer. Quality assessment will be performed using the Cochrane instrument. Metanalysis, if plausible, will be performed using Review Manager 5.3.

DISCUSSION

Studies have reported positive results of dance therapy as a non-pharmacological intervention in women with breast cancer. Thus, it is expected that robust and conclusive evidence of the effects of dance therapy during or after treatment (radiotherapy, chemotherapy, hormone therapy, and/or surgery) can be obtained.

Effect of Flywheel versus Traditional Resistance Training on Change of Direction Performance in Male Athletes: A Systematic Review with Meta-Analysis

Objective: This study aimed to systematically review and meta-analyze the effect of flywheel resistance training (FRT) versus traditional resistance training (TRT) on change of direction (CoD) performance in male athletes. Methods: Five databases were screened up to December 2021. Results: Seven studies were included. The results indicated a significantly larger effect of FRT compared with TRT (standardized mean difference [SMD] = 0.64). A within-group comparison indicated a significant large effect of FRT on CoD performance (SMD = 1.63). For TRT, a significant moderate effect was observed (SMD = 0.62). FRT of ≤2 sessions/week resulted in a significant large effect (SMD = 1.33), whereas no significant effect was noted for >2 sessions/week. Additionally, a significant large effect of ≤12 FRT sessions (SMD = 1.83) was observed, with no effect of >12 sessions. Regarding TRT, no significant effects of any of the training factors were detected (p > 0.05). Conclusions: FRT appears to be more effective than TRT in improving CoD performance in male athletes. Independently computed single training factor analyses for FRT indicated that ≤2 sessions/week resulted in a larger effect on CoD performance than >2 sessions/week. Additionally, a total of ≤12 FRT sessions induced a larger effect than >12 training sessions. Practitioners in sports, in which accelerative and decelerative actions occur in quick succession to change direction, should regularly implement FRT.

Upper Limb Stroke Rehabilitation Using Surface Electromyography: A Systematic Review and Meta-Analysis

Background

Upper limb impairment is common after stroke, and many will not regain full upper limb function. Different technologies based on surface electromyography (sEMG) have been used in stroke rehabilitation, but there is no collated evidence on the different sEMG-driven interventions and their effect on upper limb function in people with stroke.

Aim

Synthesize existing evidence and perform a meta-analysis on the effect of different types of sEMG-driven interventions on upper limb function in people with stroke.

Methods

PubMed, SCOPUS, and PEDro databases were systematically searched for eligible randomized clinical trials that utilize sEMG-driven interventions to improve upper limb function assessed by Fugl-Meyer Assessment (FMA-UE) in stroke. The PEDro scale was used to evaluate the methodological quality and the risk of bias of the included studies. In addition, a meta-analysis utilizing a random effect model was performed for studies comparing sEMG interventions to non-sEMG interventions and for studies comparing different sEMG interventions protocols.

Results

Twenty-four studies comprising 808 participants were included in this review. The methodological quality was good to fair. The meta-analysis showed no differences in the total effect, assessed by total FMA-UE score, comparing sEMG interventions to non-sEMG interventions (14 studies, 509 participants, SMD 0.14, P 0.37, 95% CI –0.18 to 0.46, I² 55%). Similarly, no difference in the overall effect was found for the meta-analysis comparing different types of sEMG interventions (7 studies, 213 participants, SMD 0.42, P 0.23, 95% CI –0.34 to 1.18, I² 73%). Twenty out of the twenty-four studies, including participants with varying impairment levels at all stages of stroke recovery, reported statistically significant improvements in upper limb function at post-sEMG intervention compared to baseline.

Conclusion

This review and meta-analysis could not discern the effect of sEMG in comparison to a non-sEMG intervention or the most effective type of sEMG intervention for improving upper limb function in stroke populations. Current evidence suggests that sEMG is a promising tool to further improve functional recovery, but randomized clinical trials with larger sample sizes are needed to verify whether the effect on upper extremity function of a specific sEMG intervention is superior compared to other non-sEMG or other type of sEMG interventions.

Efficacy and characteristics of physiotherapy interventions in patients with lumbar spinal stenosis: a systematic review

PURPOSE

To determine the efficacy of physiotherapy approaches used in the treatment of LSS and compare their delivery characteristics.

METHODS

A systematic search was conducted using MEDLINE/PubMed, EMBASE, Scopus, PEDro, CINAHL and Web of Science databases, from inception until March 2021. Inclusion criteria were clinical diagnosis of LSS confirmed through imaging techniques, RCTs written in English comparing physiotherapy interventions among them or versus placebo or usual care without restrictions on treatment and follow-up duration, outcomes related to pain, physical function, disability and quality of life. Two independent reviewers assessed records for eligibility and methodological quality (PEDro scale) and extracted participants' characteristics, interventions details and outcome measures at each timepoint. Pooled or un-pooled findings were reported as mean difference with 95% confidence interval, depending on heterogeneity. Evidence quality was rated using the GRADE approach.

RESULTS

Twelve studies (944 patients, mean PEDro score 7.6, range 5-9) were included. Three weeks of weight-supported walking improved pain and disability, while 8 weeks of aquatic exercises improved pain and walking tolerance (very low evidence). Six weeks of cycling reduced disability compared to weight-supported walking (low evidence). Six weeks of manual therapy plus exercise was not superior to supervised exercises (low evidence), but improved pain, walking tolerance, disability and quality of life compared to home/group exercises (moderate to very low evidence). Very low evidence supported 2 weeks of electromagnetic fields, whereas TENS (low evidence) and ultrasounds (very low evidence) revealed no effects.

CONCLUSIONS

These findings may assist clinicians in delivering effective physiotherapy interventions in LSS patients.

Rehabilitation interventions of unilateral spatial neglect based on the functional outcome measure: A systematic review and meta-analysis

ABSTRACTThis review aimed to examine the bottom-up and top-down rehabilitation intervention effectiveness based on the functional outcome measure as immediate effect and long-term effect for unilateral spatial neglect conditions. The RCT studies were collected by searching in three databases J-Stage, PubMed, and PEDro from 2008 through 2018. The studies which used the following instruments: BI, CBS, FMA, and FIM, as the functional outcome with the PEDro score of six and above, were eligible for inclusion. A total of 492 participants in 13 studies included from 291 studies initially identified. The meta-analysis for overall ES revealed that BI and CBS had a significant mean of SMD = 0.65 (95% CI, 0.23-1.07; p = 0.003; I2 = 65%), and SMD = -0.23 (95% CI, -0.45 to -0.01; p = 0.04; I2 = 35%) respectively, while FMA and FIM had an insignificant mean of SMD = 0.14 (95% CI, -0.08-0.37; p = 0.22; I2 = 0%), and SMD = -0.22 (95% CI, -0.69-0.25; p = 0.37; I2 = 0%) respectively. Based on the results, although indicated the heterogeneity representation across studies, it showed that the top-down intervention approach of high-frequency rTMS was more effective in enhancing the functional abilities and ADL of unilateral spatial neglect patients on the immediate effects but not necessarily in the long-term effects.

Can therapeutic exercises improve proprioception in chronic ankle instability? a systematic review and network meta-analysis

OBJECTIVE

To assess exercise therapies that aim to enhance proprioception in individuals with chronic ankle instability (CAI).

DATA SOURCES

Five databases (PubMed, Embase, Cochrane Library, Web of Science, and EBSCO) were searched in October 2021.

STUDY SELECTION

Randomized controlled trials involving exercise therapy conducted on individuals with CAI were included.

DATA EXTRACTION

Data were extracted by two independent reviewers using a standardized form. Methodological quality and risk of bias were assessed with the PEDro scale.

DATA SYNTHESIS

The end-trial weighted mean difference and standard deviations were analyzed, and the synthetic value for the improvement in error scores of ankle joint position sense (JPS) in multiple directions was evaluated.

RESULTS

Eleven trials with 333 participants were eligible for inclusion in this systematic review and were included in the Network Meta-Analysis. Foot and ankle muscle strengthening exercise showed the highest probability of being among the best treatments (surface under the cumulative ranking (SUCRA)=74.6%). The next two were static balance exercise only (SUCRA=67.9%) and corrective exercise (SUCRA=56.1%). The SUCRA values of proprioceptive exercise, dynamic balance exercise only, aquatic exercise, rehabilitation exercise with brace, mixed static/dynamic balance exercise, and control were at relatively low levels, and scored at 49.6%, 48.8%, 47.8%, 47.7%, 44.0%, and 13.5%, respectively.

CONCLUSIONS

Foot and ankle muscle strengthening exercise may have a good effect when used to improve JPS in individuals with CAI. Probably, the more complex balance exercise intervention becomes, the less effective the proprioceptive outcome.

The Effects of High-Intensity Functional Training on Cognition in Older Adults with Cognitive Impairment: A Systematic Review

(1) Background: High-Intensity Functional Training (HIFT) is a new exercise modality that emphasizes multi-joint functional movements adaptable to any fitness level and promotes greater muscle recruitment. Previous studies have evaluated the positive effects of HIFT on mental and cognitive health but have not evaluated it in older people. This study aims to conduct a systematic review of randomized controlled trials assessing the effects of HIFT on general cognition in older adults with cognitive impairment. (2) Methods: Following the PRISMA 2020 guideline, articles that did a high-intensity functional physical exercise intervention on cognitive performance in older adults with mild to moderate cognitive impairment (MMSE > 10) or dementia, aged 55 years or older, published between 2011 and 2021 in five different electronic databases: PubMed, Web of Science, Scopus, CINAHL, and Cochrane plus were included. (3) Results: 7 articles were included, all having general cognition as their primary outcome. All assessed general cognition using the Mini-Mental State Examination, the ADAS-Cog, or both. All studies had at least one HIFT experimental group with a frequency of 2 sessions per week and a variable duration between protocols of 12, 13, 16, and 26 weeks. Two articles showed that a progressive HIFT program improves general cognition, four articles showed no significant changes within or between groups and one article concluded that a HIFT intervention does not slow cognitive decline. (4) Conclusions: Evidence exists of the benefits of HIFT on general cognition in older adults with cognitive impairment, assessed using the MMSE, the ADAS-cog, or both. Two articles that showed improvement in cognitive function used progressive HIFT with 80% RM at 6, 12, and 1 weeks; however, in the other articles, due to the heterogeneity of intervention protocols, measurement time points, and control group activities, mixed results were evidenced

Active Sensory Therapies Enhancing Upper Limb Recovery Among Poststroke Subjects: A Systematic Review

Background

In stroke, sensory deficits may affect the motor recovery of the subjects. The evidence for the active sensory intervention to enhance motor recovery is sparsely available.

Purpose

To systematically review the available evidence from the studies on active sensory therapies augmenting upper limb recovery among poststroke subjects.

Methods

The following databases were searched for the desired articles: PubMed, the Cochrane Central Register of Trials (CENTRAL), DORIS, PEDro, and OTseeker. The primary search keywords were stroke, sensory, and motor. The articles published in English up to August 2021 were considered for the review. Only investigations that studied active sensory interventions to enhance motor recovery were considered for the review. The studies of robotic training, virtual reality, electrical stimulation, and acupuncture were excluded. Motor recovery and sensory recovery were considered as primary and secondary measures, respectively.

Results

Out of 3528 screened studies, eight studies were found eligible for the present systematic review. Active sensory interventions in the form of sensory discrimination, mirror therapy, motor imagery, and specific somatosensory training were utilized in the selected studies. The interventions through mirror therapy and mental imaging have some promising roles in enhancing upper limb recovery. However, there is a lack of strong evidence for the effectiveness of the intervention enhancing motor improvement among the stroke subjects.

Conclusion

A comprehensive active sensory protocol should be developed having components of cognitive, sensory, motor, and functional demand. There is a need to conduct good quality randomized trials to support the existing active sensory therapies.

Telerehabilitation for lower extremity recovery poststroke: a systematic review and meta-analysis protocol

INTRODUCTION

Approximately 30% of individuals with stroke report unmet lower extremity recovery needs after formal hospital-based rehabilitation programmes have ended. Telerehabilitation can mitigate issues surrounding accessibility of rehabilitation services by providing ongoing support to promote recovery, however, no review exists that is specific to telerehabilitation for lower extremity recovery. This paper describes the protocol of a systematic review and meta-analysis that aims to describe and evaluate the effectiveness of lower extremity-focused telerehabilitation interventions on clinical outcomes poststroke.

METHODS AND ANALYSIS

A systematic review of relevant electronic databases (MEDLINE, Embase, CINAHL, PsycINFO, Web of Science, Google Scholar, PEDro, PubMed and Cochrane Library) between inception and February 2022 will be undertaken to identify eligible interventional studies published in English that compared telerehabilitation focusing on lower extremity recovery to another intervention or usual care for individuals living in the community with stroke. Clinical outcomes examined will include those related to physical function and impairment, activities and participation that are typically assessed in clinical practice and research. Two reviewers will independently screen results, identify studies to be included for review, extract data and assess risk of bias. Meta-analyses will be performed if sufficient data exist. Sensitivity analyses will be performed by removing studies with low methodological quality, and subgroup analyses will be performed if data allow by stratifying papers based on salient demographic or stroke factors and comparing results. The reporting of the review will follow the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The quality of evidence regarding various outcomes for telerehabilitation for lower extremity recovery poststroke will be assessed according to the Grading of Recommendation, Assessment, Development and Evaluation approach.

ETHICS AND DISSEMINATION

No ethical approval or informed consent is needed for this systematic review. The findings of this review will be disseminated via peer-reviewed publications and conference presentations.

Meditation for adults with non-specific low back pain: a systematic review and meta-analysis

OBJECTIVES

We aim to determine the effectiveness of meditation for adults with non-specific low back pain.

METHODS

We searched PubMed, EMBASE, PEDro, Scopus, Web of Science, Cochrane Library, and PsycINFO databases for randomized controlled trials that investigated the effectiveness of meditation in adults with non-specific low back pain. Two reviewers rated risk of bias using the PEDro scale and the certainty of the evidence using the GRADE approach. Primary outcomes were pain intensity and disability.

RESULTS

We included eight trials with a total of 1,234 participants. Moderate-certainty evidence shows that meditation is better than usual care for disability at short-term (SMD = -0.22; 95% CI = -0.42 to -0.02). We also found that meditation is better than usual care for pain intensity at long-term (SMD = -0.28; 95% CI = -0.54 to -0.02). There is no significant difference for pain intensity between meditation and minimal intervention or usual care at short and intermediate-term. We did not find differences between meditation and minimal intervention for disability at intermediate-term or usual care in any follow-up period.

CONCLUSIONS

We found small effect sizes and moderate-certainty evidence that meditation is slightly better than minimal intervention in the short-term for disability. Low-certainty of evidence suggests that meditation is slightly better than usual care for pain in the long-term. Meditation appears to be safe with most trials reporting no serious adverse events.

Do manual therapies have a specific autonomic effect? An overview of systematic reviews

Background

The impact of manual therapy interventions on the autonomic nervous system have been largely assessed, but with heterogeneous findings regarding the direction of these effects. We conducted an overview of systematic reviews to describe if there is a specific autonomic effect elicited by manual therapy interventions, its relation with the type of technique used and the body region where the intervention was applied.

Methods

We conducted an overview according to a publicly registered protocol. We searched the Cochrane Database of Systematic Reviews, MEDLINE, EPISTEMONIKOS and SCOPUS, from their inception to march 2021. We included systematic reviews for which the primary aim of the intervention was to assess the autonomic effect elicited by a manual therapy intervention in either healthy or symptomatic individuals. Two authors independently applied the selection criteria, assessed risk of bias from the included reviews and extracted data. An established model of generalisation guided the data analysis and interpretation.

Results

We included 12 reviews (5 rated as low risk of bias according the ROBIS tool). The findings showed that manual therapies may have an effect on both sympathetic and parasympathetic systems. However, the results from included reviews were inconsistent due to differences in their methodological rigour and how the effects were measured. The reviews with a lower risk of bias could not discriminate the effects depending on the body region to which the technique was applied.

Conclusion

The magnitude of the specific autonomic effect elicited by manual therapies and its clinical relevance is uncertain. We point out some specific recommendations in order to improve the quality and relevance of future research in this field.

Cognitive-behavioral therapy and urge urinary incontinence in women. A systematic review

INTRODUCTION AND HYPOTHESIS

UUI co-exists with numerous health conditions, having a substantial negative impact on health-related quality of life and mental health. Cognitive-behavioral therapy (CBT) could help patients manage these problems by changing the way they think and behave.

METHODS

We carried out a systematic review of the literature assessing the modalities and effects of CBT as a stand-alone strategy, without adding PFMT, on symptoms and clinical signs, in women with UUI. Our secondary objective was to report modalities and effects of CBT on health-related quality of life, psychological symptoms and patient-reported satisfaction. The PRISMA methodology was used to carry out this systematic review. A literature search was conducted in PubMed, PEDro, Web of Science and Cochrane Library databases from inception to December 2020. The PICO approach was used to determine the eligibility criteria.

RESULTS

Twelve papers were included in the present review which showed beneficial effects on both symptom severity (p < 0.05) and more subjective areas such as quality of life, psychological symptoms or patient satisfaction level (p < 0.05), respectively). However, results on the effectiveness of CBT on clinical signs remains conflicting.

CONCLUSION

Based on the available literature, this review suggested a high level of evidence for the effectiveness of CBT on symptom severity and a moderate level of evidence for the effectiveness of CBT on quality of life, psychological symptoms and patient satisfaction. However, we highlighted no evidence for the effects of CBT on clinical signs.

Effects of Plyometric Jump Training on Balance Performance in Healthy Participants: A Systematic Review With Meta-Analysis

Background: Postural balance represents a fundamental movement skill for the successful performance of everyday and sport-related activities. There is ample evidence on the effectiveness of balance training on balance performance in athletic and non-athletic population. However, less is known on potential transfer effects of other training types, such as plyometric jump training (PJT) on measures of balance. Given that PJT is a highly dynamic exercise mode with various forms of jump-landing tasks, high levels of postural control are needed to successfully perform PJT exercises. Accordingly, PJT has the potential to not only improve measures of muscle strength and power but also balance. Objective: To systematically review and synthetize evidence from randomized and non-randomized controlled trials regarding the effects of PJT on measures of balance in apparently healthy participants. Methods: Systematic literature searches were performed in the electronic databases PubMed, Web of Science, and SCOPUS. A PICOS approach was applied to define inclusion criteria, (i) apparently healthy participants, with no restrictions on their fitness level, sex, or age, (ii) a PJT program, (iii) active controls (any sport-related activity) or specific active controls (a specific exercise type such as balance training), (iv) assessment of dynamic, static balance pre- and post-PJT, (v) randomized controlled trials and controlled trials. The methodological quality of studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. This meta-analysis was computed using the inverse variance random-effects model. The significance level was set at p <0.05. Results: The initial search retrieved 8,251 plus 23 records identified through other sources. Forty-two articles met our inclusion criteria for qualitative and 38 for quantitative analysis (1,806 participants [990 males, 816 females], age range 9-63 years). PJT interventions lasted between 4 and 36 weeks. The median PEDro score was 6 and no study had low methodological quality (≤3). The analysis revealed significant small effects of PJT on overall (dynamic and static) balance (ES = 0.46; 95% CI = 0.32-0.61; p < 0.001), dynamic (e.g., Y-balance test) balance (ES = 0.50; 95% CI = 0.30-0.71; p < 0.001), and static (e.g., flamingo balance test) balance (ES = 0.49; 95% CI = 0.31-0.67; p < 0.001). The moderator analyses revealed that sex and/or age did not moderate balance performance outcomes. When PJT was compared to specific active controls (i.e., participants undergoing balance training, whole body vibration training, resistance training), both PJT and alternative training methods showed similar effects on overall (dynamic and static) balance (p = 0.534). Specifically, when PJT was compared to balance training, both training types showed similar effects on overall (dynamic and static) balance (p = 0.514). Conclusion: Compared to active controls, PJT showed small effects on overall balance, dynamic and static balance. Additionally, PJT produced similar balance improvements compared to other training types (i.e., balance training). Although PJT is widely used in athletic and recreational sport settings to improve athletes' physical fitness (e.g., jumping; sprinting), our systematic review with meta-analysis is novel in as much as it indicates that PJT also improves balance performance. The observed PJT-related balance enhancements were irrespective of sex and participants' age. Therefore, PJT appears to be an adequate training regime to improve balance in both, athletic and recreational settings.

The effect of Pilates exercise training for scoliosis on improving spinal deformity and quality of life: Meta-analysis of randomized controlled trials

BACKGROUND

It remains unclear if Pilates is conducive to reducing spinal deformity and improving patients' quality of life (QOL) with scoliosis. The aim of this study was to systematically review the published evidence to determine whether Pilates exercise training is an efficacious therapy for scoliosis.

METHODS

Searches was conducted in Medline, Embase, PubMed, Scopus, CINAHL, Physiotherapy Evidence Database (PEDro), Cochrane library, Baidu Scholar, and Green Medical to identify randomized studies that tested the effect of Pilates exercise training on Cobb angle, pain level, trunk range of motion (ROM), angle of trunk rotation, and QOL in idiopathic scoliosis. Separate meta-analyses were performed on the endpoints of these outcome measures. The PEDro scale was used to assess the methodological quality of the included studies.

RESULTS

This review included 10 randomized controlled trials (n = 359). PEDro scores ranged from 3 to 10, with the mean score across all articles being 5.3/10 and judged to be of fair quality. The results indicated that Pilates exercises was effective in reducing Cobb angle (standardized mean difference [SMD] = 1.23, 95% confidence interval [CI] = 0.11-2.35), angle of trunk rotation (SMD = 1.37, 95% CI = 1.01-1.73), and pain level (SMD = 2.78, 95% CI = 1.55-4.01), as well as improving trunk ROM (SMD = 1.23, 95% CI = 0.45-2.00), and QOL (SMD = 3.05, 95% CI = 2.59-3.51) in patients with scoliosis.

CONCLUSION

Pilates exercise training may reduce the Cobb angle and trunk rotation, relieve pain, increase trunk ROM, and improve QOL for patients with scoliosis. Due to the poor quality of the evidence, however, these results should be interpreted with caution.

Systematic review and meta-analysis of randomised controlled trials on the effects of yoga in people with Parkinson's disease

PURPOSE

Yoga may be a beneficial treatment for people with Parkinson's disease (PD). However, no studies have critically reviewed and meta-analyzed the scientific evidence for yoga's benefits regarding motor and non-motor symptoms. The purpose of this study was to conduct a systematic review and meta-analysis on the effectiveness of yoga as a rehabilitation strategy for PD.

MATERIALS AND METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a literature search was performed using MEDLINE/PubMed, PEDro, SPORTDiscus, and Scopus. Studies addressing any concepts on the impact of yoga intervention on physical and psychological outcomes in people with PD were included.

RESULTS

Fourteen RCTs were selected, with heterogeneous protocols and outcomes measures. Yoga interventions were safe and well-accepted for patients with mild to moderate PD. The descriptive analysis indicated that its practice might provide both physical and psychological benefits. Preliminary evidence showed that yoga has comparable or superior efficacy to exercise. A subsequent meta-analysis on five RCTs detected that yoga was more effective than passive control in ameliorating motor symptoms.

CONCLUSIONS

Yoga appears to be a promising rehabilitative therapy for individuals with PD. Recommendations are proposed for future studies.IMPLICATIONS FOR REHABILITATIONYoga is a safe and feasible therapy for people with mild to moderate PD.Yoga practice positively impacts physical and mental health in this population.When compared to exercise, yoga showed to have similar or even greater effects.

Exercise therapy for sarcopenia in rheumatoid arthritis: A meta-analysis and meta-regression of randomized controlled trials

OBJECTIVE

Rheumatoid arthritis and age are associated with high sarcopenia risk. Exercise is an effective treatment for preventing muscle mass loss in older adult populations. It remains unclear whether exercise affects muscle mass in people with rheumatoid arthritis. Thus, this meta-analysis investigated the effect of exercise on muscle mass gain in patients with rheumatoid arthritis.

DATA SOURCES

PubMed, EMBASE, the Cochrane Library, the Physiotherapy Evidence Database (PEDro), the China Knowledge Resource Integrated Database, and Google Scholar were systematically searched until June 2021.

METHODS

The present study was conducted according to the guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Randomized controlled trials (RCTs) that reported the effects of exercise on muscle mass for rheumatoid arthritis were identified. The included RCTs were subject to meta-analysis and risk of bias assessment. Subgroup and random-effects meta-regression analyses were performed to identify any heterogeneity (I²) of treatment effects across studies.

RESULTS

We included nine RCTs with a median PEDro score of 6/10 (range: 4/10-8/10). The weighted mean effect size for muscle mass was 0.77 (95% CI: 0.30-1.24; P = 0.001; I² = 77%). Meta-regression analyses indicated that the disease duration significantly explained variance of treatment effects across studies (β = -0.006, R² = 69.7%, P = 0.005).

CONCLUSIONS

Exercise therapy effectively increased muscle mass in patients with rheumatoid arthritis. Treatment effects may be attenuated in those who have had rheumatoid arthritis for a relatively long time.

Are Probiotics and Prebiotics Safe for Use during Pregnancy and Lactation? A Systematic Review and Meta-Analysis

Probiotic and prebiotic products have shown potential health benefits, including for the prevention of adverse pregnancy outcomes. The incidence of adverse effects in pregnant people and their infants associated with probiotic/prebiotic/synbiotic intake, however, remains unclear. The objectives of this study were to evaluate the evidence on adverse effects of maternal probiotic, prebiotic, and/or synbiotic supplementation during pregnancy and lactation and interpret the findings to help inform clinical decision-making and care of this population. A systematic review was conducted following PRISMA guidelines. Scientific databases were searched using pre-determined terms, and risk of bias assessments were conducted to determine study quality. Inclusion criteria were English language studies, human studies, access to full-text, and probiotic/prebiotic/synbiotic supplementation to the mother and not the infant. In total, 11/100 eligible studies reported adverse effects and were eligible for inclusion in quantitative analysis, and data were visualised in a GOfER diagram. Probiotic and prebiotic products are safe for use during pregnancy and lactation. One study reported increased risk of vaginal discharge and changes in stool consistency (relative risk [95% CI]: 3.67 [1.04, 13.0]) when administering Lactobacillus rhamnosus and L. reuteri. Adverse effects associated with probiotic and prebiotic use do not pose any serious health concerns to mother or infant. Our findings and knowledge translation visualisations provide healthcare professionals and consumers with information to make evidence-informed decisions about the use of pre- and probiotics.

A systematic review and meta-analysis of the effects of early mobilization therapy in patients after cardiac surgery

BACKGROUND

Prolonged hospitalization and immobility of critical care patients elevate the risk of long-term physical and cognitive impairments. However, the therapeutic effects of early mobilization have been difficult to interpret due to variations in study populations, interventions, and outcome measures. We conducted a meta-analysis to assess the effects of early mobilization therapy on cardiac surgery patients in the intensive care unit (ICU).

METHODS

PubMed, Excerpta Medica database (EMBASE), Cumulative Index of Nursing and Allied Health Literature (CINAHL), Physiotherapy Evidence Database (PEDro), and the Cochrane Library were comprehensively searched from their inception to September 2018. Randomized controlled trials were included if patients were adults (≥18 years) admitted to any ICU for cardiac surgery due to cardiovascular disease and who were treated with experimental physiotherapy initiated in the ICU (pre, post, or peri-operative). Data were extracted by 2 reviewers independently using a pre-constructed data extraction form. Length of ICU and hospital stay was evaluated as the primary outcomes. Physical function and adverse events were assessed as the secondary outcomes. Review Manager 5.3 (RevMan 5.3) was used for statistical analysis. For all dichotomous variables, relative risks or odds ratios with 95% confidence intervals (CI) were presented. For all continuous variables, mean differences (MDs) or standard MDs with 95% CIs were calculated.

RESULTS

The 5 studies with a total of 652 patients were included in the data synthesis final meta-analysis. While a slight favorable effect was detected in 3 out of the 5 studies, the overall effects were not significant, even after adjusting for heterogeneity.

CONCLUSIONS

This population-specific evaluation of the efficacy of early mobilization to reduce hospitalization duration suggests that intervention may not universally justify the labor barriers and resource costs in patients undergoing non-emergency cardiac surgery.

Clinical effectiveness of shockwave therapy in lateral elbow tendinopathy: systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of extracorporeal shockwave therapy compared with other interventions on pain, grip strength and disability in patients with lateral elbow tendinopathy.

DATA SOURCES

MEDLINE, PubMed, CINAHL, EMBASE, PEDro, ScienceDirect, Cochrane Library and clinical trial registries.

REVIEW METHODS

We included randomized controlled trials assessing the effectiveness of extracorporeal shockwave therapy alone or as an additive intervention compared with sham or other interventions. Pain intensity, grip strength and elbow disability were used as primary outcome measures. We assessed methodological quality with the PEDro score and quality of evidence with the GRADE approach.

RESULTS

Twenty-seven studies with 1871 patients were finally included. Extracorporeal shockwave therapy reduced pain intensity at mid-term follow-up (standardized mean difference: -1.21, 95% confidence interval:-1.53, -0.89, P < 0.001) and improved grip strength at very short- (mean difference:3.92, 95% confidence interval: 0.91, 6.94, P = 0.01) and short-term follow-up (mean difference:4.87, 95% confidence interval:2.24, 7.50, P < 0.001) compared with sham treatment. However, no clinically significant results were found between comparators in all outcomes and follow-up times. Extracorporeal shockwave therapy presented clinically better compared to Laser in grip strength at short-term (mean difference:3.50, 95% confidence interval:2.40, 4.60, P < 0.001) and ultrasound in pain intensity at very-short-term follow-up (standardized mean difference: -1.54, 95% confidence interval: -2.60, -0.48, P = 0.005).

CONCLUSION

Low to moderate certainty of evidence suggests that there are no clinical benefits of extracorporeal shockwave therapy compared to sham interventions or corticosteroid injections. Based on very-low and moderate certainty of evidence, extracorporeal shockwave therapy outperforms against Laser and ultrasound, respectively.Level of Evidence: Therapy, level 1a.

Exercise-Based Muscle Development Programmes and Their Effectiveness in the Functional Recovery of Rotator Cuff Tendinopathy: A Systematic Review

(1) Background: Rotator cuff (RC) tendinopathy causes pain and functional limitation of the shoulder. Physical exercises are effective therapies but there is no consensus on which exercise programme is the most appropriate. Objective: To analyze and compare the effectiveness of different intervention modalities-based exclusively on physical exercise muscle-development programs to improve shoulder pain and function in RC tendinopathy. (2) Methods: Systematic review (PRISMA) through a search in PubMed, WOS, PEDro, Cinahl, Scopus and Dialnet. The PEDro Scale and the Cochrane Risk of Bias analyzed the methodological quality. A pre-established table collected data on: patients, interventions, outcome measures and results. A narrative synthesis of the results was conducted. (3) Results: eight articles were selected (Cochrane: low risk of bias; PEDro: good quality). All assessed programs were effective. Only one study found statistically and clinically significant differences in favour of eccentric training. The exercises used were: eccentric/concentric/conventional, open/closed kinetic chain, with/without co-activation of glenohumeral muscle, with/without pain, and in clinic/at home. (4) Conclusions: All exercise programs were effective in RC tendinopathy, improving pain and shoulder function. No solid results were obtained when the interventions were compared due to their heterogeneity. Patients perception assessment tools were the most widely used. Amount of load applied should be considered.

What is the impact of robotic rehabilitation on balance and gait outcomes in people with multiple sclerosis? A systematic review of randomized control trials

INTRODUCTION

In recent years, robot-assisted gait training (RAGT) has been proposed as therapy for balance and gait dysfunctions in people with multiple sclerosis (PwMS). Through this systematic review, we aimed to discuss the impact of RAGT on balance and gait outcomes. Furthermore, characteristics of the training in terms of robots used, participants characteristics, protocols and combined therapeutic approaches have been described.

EVIDENCE ACQUISITION

As part of the Italian Consensus on robotic rehabilitation "CICERONE" a systematic search was provided in PubMed, the Cochrane Library and PEDro to identify relevant studies published before December 2019. Only randomized control trials (RCT) involving RAGT for PwMS were included. PEDro scale was used to assess the risk of bias and the Oxford Center for Evidence-Based Medicine (OCEBM) was used to assess level of evidence of included studies.

EVIDENCE SYNTHESIS

The search on databases resulted in 336 records and, finally, 12 studies were included. RAGT was provided with Exoskeleton in ten studies (6-40 session, 2-5 per week) and with end-effector in two studies (12 sessions, 2-3 per week) with large variability in terms of participants' disability. All the exoskeletons were combined with bodyweight support treadmill and movement assistance varied from 0% to 100% depending on participants' disability, two studies combined exoskeleton with virtual reality. The end-effector speed ranged between 1.3 and 1.8 km/h, with bodyweight support starting from 50% and progressively reduced. In seven out of twelve studies RAGT was provided in a multimodal rehabilitation program or in combination with standard physical therapy. There is level 2 evidence that RAGT has positive impact in PwMS, reaching the minimally clinically importance difference in Berg Balance Scale, six-minute walking test and gait speed.

CONCLUSIONS

In available RCT, RAGT is mostly provided with exoskeleton devices and improves balance and gait outcomes in a clinically meaningful way. Considering several advantages in terms of safety, motor assistance and intensity of training provided, RAGT should be promoted for PwMS with severe disability in a multimodal rehabilitation context as an opportunity to maximize recovery.

Leisure-time physical activity interventions for children and adults with cerebral palsy: a scoping review

AIM

To summarize current evidence on the effects and reach of leisure-time physical activity (LTPA) interventions among children and adults with cerebral palsy (CP).

METHOD

Systematic searches were conducted in PubMed, CINAHL, and Google Scholar to identify randomized controlled trials (RCTs) of LTPA interventions in CP. Data from eligible studies were extracted for qualitative synthesis.

RESULTS

Forty-nine studies enrolled a total of 1513 participants (mean [SD] age 13y [7y], range 5-43y; 818 males, 655 females, 40 not reported) and primarily included ambulatory children. RCTs underrepresented adults and people in Gross Motor Function Classification System (GMFCS) levels IV and V. Forty-one studies reported at least one favorable benefit from LTPA. Benefits included improvements to musculoskeletal strength, cardiorespiratory fitness, quality of life, spasticity, participation, and core aspects of physical function. Regarding reach, only 34% of people that were contacted to participate enrolled within a study. A smaller percentage of participants dropped out from intervention (8%) and follow-up periods (3%).

INTERPRETATION

Study findings highlight effective interventions to improve health, fitness, and function. To enhance the reach and generalizability of LTPA trials for CP, future studies should examine how to increase study sample sizes and aim to include a better representation of adults and people in GMFCS levels IV and V.

WHAT THIS PAPER ADDS

People with cerebral palsy (CP) may experience improvements in health, fitness, and physical function from leisure-time physical activity (LTPA) interventions. Effective interventions include exercise training, active video games, recreation activities, behavioral coaching, and motor skills training. Interventions that incorporate telehealth technology, behavioral coaching, and community resources may enhance LTPA. Interventions primarily include children in Gross Motor Functional Classification System (GMFCS) levels I to III. Adults, wheelchair users, and those in GMFCS levels IV and V are underrepresented.

Interventions for Trismus in Head and Neck Cancer Patients: A Systematic Review of Randomized Controlled Trials

BACKGROUND

Current treatment for head and neck cancers (HNCs) have led to an improved survival. However, the sequelae of cancer treatment often result in trismus, or reduced mouth opening. The purpose of this report is to identify interventional studies for trismus management in HNC patients.

METHODS

A search of PubMed, Embase, Cumulated Index to Nursing and Allied Health Literature, and the Cochrane Library was conducted in March 2020 for randomized controlled trials (RCTs) involving interventions for trismus for head and neck cancer within 10 years. Intervention could involve the use of an exercise regime, jaw rehabilitation device, technological device, medication or massage therapy. The primary outcome was the measurement of mouth opening.

RESULTS

Eleven RCTs involving a total of 685 patients with HNC were included. Six RCTs evaluated the effectiveness of a jaw mobilization device with exercises; there was no significant benefit of an exercise regime with a jaw mobilization device either initiated before, during or after treatment compared to no exercise. Two RCTs compared 2 intervention groups that involved exercises only, with 1 study assessing the benefit of weekly supervised physical therapy with gum chewing and another evaluating the benefit of immediate (1-2 days) versus delayed (7-10 days) initiation of exercise post-surgery; there was no significant difference between groups in either study. One RCT that recruited only patients with trismus demonstrated that an exercise regime in combination with low-level laser therapy or low-intensity ultrasound had superior results in mouth opening measurements compared to exercise alone. Two RCTs compared intervention groups with and without follow-up reminders; both studies showed a significant improvement in mouth opening measurements in groups with follow-up reminders.

CONCLUSION

This systematic review did not convey a clear consensus as to optimal intervention for trismus in HNC patients. A variety of exercise regimens and jaw rehabilitation devices appear to have comparable effectiveness. However, efforts focused on increasing adherence to a particular intervention protocol may positively impact mouth opening measures in head and neck cancer patients. Also, low-level laser therapy and low-intensity ultrasound coupled with exercise may be beneficial for patients with trismus.

Should low-quality evidence dominate high-level evidence? A systematic review and meta-analysis of systematic reviews of musculoskeletal physical therapy interventions

OBJECTIVES

To determine the: 1) quality of articles cited in systematic reviews (SRs); 2) methodological quality of the SRs; and 3) impact of quality on level 1A evidence.

METHODS

SRs related to musculoskeletal physical therapy interventions were identified. The methodological quality of the SRs and articles cited by the SRs were assessed by two blinded reviewers. Data analysis was performed by a third blinded researcher. Additional comparisons were made based on the Journal Impact Factor, spin, financial bias, and conflict of interest.

RESULTS

Twenty-four SRs were identified; 21/24 SRs had 'critically low' quality on the AMSTAR 2. Thirty-four percent of included studies were 'low quality,' and 58% of SRs included studies that had unreported external validity. One-half of the SRs represented 'spin,' and one-third of the SRs generated conclusions based on low-quality clinical trials.

DISCUSSION

The 'critically low' SRs methodological quality was exacerbated by low-quality research inclusion. Most SRs failed to follow best practices, including prospective registration and integration of professional librarians in the search process. Based on the high proportion of SRs that include low-quality trials and overall low methodological quality, further discussion regarding practice recommendations on level vs. quality of evidence is warranted.

Robot-Assisted Arm Training versus Therapist-Mediated Training after Stroke: A Systematic Review and Meta-Analysis

Background

More than two-thirds of stroke patients have arm motor impairments and function deficits on hospital admission, leading to diminished quality of life and reduced social participation. Robot-assisted training (RAT) is a promising rehabilitation program for upper extremity while its effect is still controversial due to heterogeneity in clinical trials. We performed a systematic review and meta-analysis to compare robot-assisted training (RAT) versus therapist-mediated training (TMT) for arm rehabilitation after stroke.

Methods

We searched the following electronic databases: MEDLINE, EMBASE, Cochrane EBM Reviews, and Physiotherapy Evidence Database (PEDro). Studies of moderate or high methodological quality (PEDro score ≥4) were included and analyzed. We assessed the effects of RAT versus TMT for arm rehabilitation after stroke with testing the noninferiority of RAT. A small effect size of -2 score for mean difference in Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) and Cohen's d = -0.2 for standardized mean difference (SMD) were set as noninferiority margin.

Results

Thirty-five trials with 2241 participants met inclusion criteria. The effect size for arm motor impairment, capacity, activities of daily living, and social participation were 0.763 (WMD, 95% CI: 0.404 to 1.123), 0.109 (SMD, 95% CI: -0.066 to 0.284), 0.049 (SMD, 95% CI: -0.055 to 0.17), and -0.061 (SMD, 95% CI: -0.196 to 0.075), respectively.

Conclusion

This systematic review and meta-analysis demonstrated that robot-assisted training was slightly superior in motor impairment recovery and noninferior to therapist-mediated training in improving arm capacity, activities of daily living, and social participation, which supported the use of RAT in clinical practice.

The effectiveness of preoperative rehabilitation programmes on postoperative outcomes following anterior cruciate ligament (ACL) reconstruction: a systematic review

BACKGROUND

To explore the effectiveness of preoperative rehabilitation programmes (PreHab) on postoperative physical and psychological outcomes following anterior cruciate ligament reconstruction (ACLR).

METHOD

A systematic search was conducted from inception to November 2019. Randomised controlled trials (RCTs) published in English were included. Risk of bias was assessed using Version 2 of the Cochrane risk-of-bias tool, and the Grading of Recommendations Assessment system was used to evaluate the quality of evidence.

RESULTS

The search identified 739 potentially eligible studies, three met the inclusion criteria. All included RCTs scored 'high' risk of bias. PreHab in all three RCTs was an exercise programme, each varied in content (strength, control, balance and perturbation training), frequency (10 to 24 sessions) and length (3.1- to 6-weeks). Statistically significant differences (p < 0.05) were reported for quadriceps strength (one RCT) and single leg hop scores (two RCTs) in favour of PreHab three months after ACLR, compared to no PreHab. One RCT reported no statistically significant between-group difference for pain and function. No RCT evaluated post-operative psychological outcomes.

CONCLUSION

Very low quality evidence suggests that PreHab that includes muscular strength, balance and perturbation training offers a small benefit to quadriceps strength and single leg hop scores three months after ACLR compared with no PreHab. There is no consensus on the optimum PreHab programme content, frequency and length. Further research is needed to develop PreHab programmes that consider psychosocial factors and the measurement of relevant post-operative outcomes such as psychological readiness and return to sport.

Effectiveness of yoga on arterial stiffness: A systematic review

OBJECTIVES

Arterial stiffness is a major cardiovascular (CV) risk and an independent strong predictor of CV morbidity and mortality. The aim of this systematic review is to evaluate the clinical or interventional studies that assessed the effectiveness of yoga on arterial stiffness in participants of any age or sex, healthy or with any conditions.

DESIGN

Systematic review of clinical trials or interventional studies.

DATA SOURCES

Cochrane Library, Medline/PubMed, Scopus, and Google Scholar databases.

REVIEW METHODS

Databases were searched till July 2019 for clinical trials or interventional studies whether controlled or uncontrolled, randomized or non-randomized studies assessing the effects of yoga on arterial stiffness. Quality of the studies was assessed by using Physiotherapy Evidence Database (PEDro) Scale.

RESULTS

Seven full-text articles (total number of participants = 362) that evaluated the effect of yoga on arterial stiffness were included in this review. There were three randomized controlled studies and four were non-controlled studies (single group studies). Four studies have shown significant reduction in arterial stiffness, while three studies did not find any significant change in arterial stiffness. The beneficial effects of yoga intervention on arterial stiffness in young adults and elderly hypertensive patients are encouraging. Methodological quality was good for one study, moderate for two studies and poor for four studies.

CONCLUSIONS

This review shows that yoga practice is effective in preventing or reducing the arterial stiffness in young healthy and obese, and elderly hypertensive patients. As the methodology of many studies is of low quality and safety measures were not reported, there is a need of quality randomized controlled trials of yoga effects on arterial stiffness among high risk individuals.

Effect of Cold Application on Bruising and Pain Following Heparin Subcutaneous Injection: A Systematic Review and Meta-Analysis

PURPOSE

We performed this review systematically to assess the effect of cold application at the heparin subcutaneous injection site on incidence and size of bruising, hematoma, and pain intensity.

DESIGN

A systematic review and meta-analysis were utilized as the study design.

DATA SOURCES

To retrieve the relevant randomized controlled trials (RCTs) published up to July 2019, the databases of PubMed, Scopus, Web of Science, ScienceDirect, Cochrane Library, Google Scholar, TRIP, and Elmnet.ir were searched.

REVIEW METHODS

Those RCTs were selected in which the participants had received any type of heparin via subcutaneous injections at least once a day, as were those comparing the effect of cold application (i.e., moist or dry ice packs or vapocoolant spray) on injection sites with no interventions or placebos. The types of outcomes measured included pain intensity, bruising, and hematoma at injection sites. Furthermore, odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs) were employed to measure the pooled data.

RESULTS

A total of nine studies recruiting 896 patients with a mean age range of 37 to 62 years were ultimately included in this study. The findings revealed that eight studies had used low-molecular-weight heparin, but unfractionated heparin had been administered in one study. The quality of the studies was also assessed in seven domains. Overall, risk of bias in the included articles was low to moderate. Pooling data of six studies showed that the patients had experienced less pain intensity once cold had been applied at the heparin injection sites (MD = -1.67; 95% CI -3.03 to -0.31; p = .02; I² = 92%). Bruising had been correspondingly reported in eight and six studies in terms of size and incidence, respectively. In particular, the results had demonstrated no statistically significant difference between either group in terms of bruising size or incidence at 48 to 72 hr following heparin injection. Furthermore, hematoma incidence had been reported in two studies, and one trial had reported hematoma size only. The results had suggested that the patients had smaller hematomas (MD = -0.87; 95% CI -1.63 to -0.11; p = .03) and a lower incidence of hematomas (OR = 0.35; 95% CI 0.16 to 0.76; p = .008) in the cold application group 48 hr after injection.

CONCLUSIONS

The results of this systematic review and meta-analysis showed that patients could experience less pain and fewer hematomas once the cold had been applied for 3 to 5 min at the injection sites before or after subcutaneous heparin administration. During this period, clinicians should also consider the patient's comfort; if some patients feel discomfort at the cold application site, the minimum possible time should be considered.

Effectiveness of scoliosis-specific exercises for alleviating adolescent idiopathic scoliosis: a systematic review

Background

Adolescent idiopathic scoliosis (AIS) is the most common pediatric spinal deformity with reported complications including pain, mental health concern and respiratory dysfunction. The scoliosis-specific exercise (SSE) is prescribed throughout pubertal growth to slow progression although effects are unclear. This review aims to establish the effectiveness of SSE for alleviating AIS in terms of reducing Cobb angle, improving trunk asymmetry and quality of life (QoL). Additionally, it aims to define the effects of age, skeletal maturity, curve magnitude and exercise compliance on the outcomes of SSE.

Methods

A systematic reviewed was conducted to net SSE articles. Searched databases included PubMed, MEDLINE, Cochrane Library, Scopus, CINAHL and Google scholar. The quality of study was critically appraised according to the PEDro scale.

Results

A total of ten trials with an average PEDro score of 6.9/10 were examined in this study. Two randomized controlled trials (RCTs) and two clinical controlled trials suggested that SSE alone and with bracing or traditional exercise had clinical significance in reducing Cobb angle more than 5°. One RCT specifically implicated no comparable effects between bracing and SSE in prevention of curve progression for moderate scoliosis. There was insufficient evidence to support the positive effects of SSE on improving truck asymmetry (n = 4) and QoL (n = 3). Five studies evaluated the interaction effects of age (n = 2), skeletal maturity (n = 1) and curve magnitude (n = 2) with SSE in reducing Cobb angle yet without drawing any firm conclusions.

Conclusions

Insufficient evidence is available to prove that SSE with or without other conservative treatments can reduce Cobb angle, improve trunk balance and QoL. The interaction effects of age, skeletal maturity, curve magnitude, and exercise compliance with SSE in reducing Cobb angle are not proven. Future studies should investigate the relationship of influencing factors and SSE in treating AIS but not only testing its effectiveness.

Inter-review agreement of risk-of-bias judgments varied in Cochrane reviews

OBJECTIVES

The objective of the study was to measure the level of agreement between Cochrane reviews of overlapping randomized controlled trials (RCTs) regarding risk-of-bias (RoB) judgments.

STUDY DESIGN AND SETTING

On November 5, 2017, the Cochrane Database of Systematic Reviews was searched for Cochrane reviews on tobacco. Reviews that included overlapping RCTs were included. RoB judgments were extracted from RoB tables using automated data scraping with manual verification and adjustments. Agreement between the reviews was calculated using Conger's generalized kappa coefficient (κ) and raw agreement (a).

RESULTS

We included 53 Cochrane reviews of 376 RCTs. For the RoB domain "random sequence generation," the level of agreement between the reviews was substantial with κ = 0.63 (95% confidence interval: 0.56 to 0.71; a = 0.80). There was slight-to-moderate agreement between the reviews regarding the domains "allocation concealment": κ = 0.51 (0.41 to 0.61), a = 0.75; "blinding": κ = 0.19 (0.02 to 0.37), a = 0.52; "blinding of outcome assessment": κ = 0.43 (0.14 to 0.72) a = 0.67; and "incomplete outcome data": κ = 0.15 (-0.03 to 0.32), a = 0.64. For "blinding of participants and personnel" and "selective reporting", κ could not be calculated. The raw agreement was 0.40 and 0.42, respectively.

CONCLUSION

The level of agreement between Cochrane reviews regarding RoB judgments ranged from slight to substantial depending on the RoB domain. Further investigations regarding reasons for variation and interventions to improve agreement are needed.
