Effectiveness of Treadmill Training on Walking Ability in Adults with Cerebral Palsy: A Systematic Review and Meta-Analysis

Background: Patients with cerebral palsy (CP) may necessitate long-term treatment and monitoring of their condition, not only during the period of development but also during adulthood. Objectives: This systematic review aimed to analyze evidence from randomized controlled trials (RCTs) that have investigated the effect of treadmill training on walking ability in adults with cerebral palsy. Methods: RCTs were identified and selected systematically, with appropriate keywords applied in four scientific databases (Medline, Scopus, the Cochrane Library, and the Physiotherapy Evidence Database) and one bibliographic search engine (Google Scholar) from January 1980 to September 2021. Two assessors extracted and analyzed data from relevant RCTs published in English and then independently rated those studies for risk of bias with the Risk of Bias (RoB 2) tool. Results: Out of the 96 studies that were initially identified, 93 were excluded, as these either did not meet the inclusion criteria or were duplicates. Three clinical trials were finally included, characterized by some concerns and a high risk of bias (RoB 2). Meta-analysis was only performed for the maximum distance in the ‘6-minute walk for distance test’, due to differences in the remaining outcomes utilized between studies. Overall, there was evidence of some concerns and high risk of bias that treadmill training did not significantly improve the walking ability in adult patients with CP relative to the control conditions. Conclusion: More high-quality RCTs are required, examining the effectiveness of treadmill training on different aspects of walking ability such as gait speed, endurance, and energy expenditure

The Effect of Virtual Reality Intervention Programs on the Functionality of Children and Adolescents with Cerebral Palsy. A Systematic Review

Background: Cerebral Palsy (CP) is a neurological disorder of movement and posture. Recent studies have shown that Virtual Reality (VR) is a useful and low-cost tool used in treating children and adolescents with cerebral palsy. Nevertheless, there is no substantial evidence supporting that VR therapy can help CP patients, not only as the primary treatment, but as a supplement. Objectives: The present systematic review aimed to investigate the effectiveness of VR intervention programs on the functional capacity of children and adolescents with CP, according to the International Classification of Functioning, Disability and Health (ICF). Methods: A systematic online search was conducted in PubMed, Scopus, and PEDro databases, as well as in the Google Scholar search engine, from inception till September 2022. The methodological quality of included studies was rated with the PEDro scale. Results: Twenty-two randomized-controlled trials were eligible for inclusion. The results indicated that there was a significant improvement after the implementation, of interventional VR programs, in balance and visual perception, while the results were controversial for muscle strength, coordination, gross motor function, gait, upper limb function, independence in activities of Daily Life Activities and participation. Conclusion: Significant balance and visual perception improvements may result from VR programs applied in children and adolescents with CP. Important factors that may influence the results are the functional level of the participants, the sample size, the context in which the therapeutic intervention is carried out (rehabilitation center, home), and the conventional treatments that the VR intervention programs are compared against

Clinical trials evaluating the efficacy of a variety of interventions for chronic non-specific low back pain indicate limited effectiveness for most commonly applied interventions and approaches. Discussion: Many clinicians challenge the results of clinical trials as they feel that this lack of effectiveness is at odds with their clinical experience of managing patients with back pain. A common explanation for this discrepancy is the perceived heterogeneity of patients with chronic non-specific low back pain. It is felt that the effects of treatment may be diluted by the application of a single intervention to a complex, heterogeneous group with diverse treatment needs. This argument presupposes that current treatment is effective when applied to the correct patient. An alternative perspective is that the clinical trials are correct and current treatments have limited efficacy. Preoccupation with sub-grouping may stifle engagement with this view and it is important that the sub-grouping paradigm is closely examined. This paper argues that there are numerous problems with the sub-grouping approach and that it may not be an important reason for the disappointing results of clinical trials. We propose instead that current treatment may be ineffective because it has been misdirected. Recent evidence that demonstrates changes within the brain in chronic low back pain sufferers raises the possibility that persistent back pain may be a problem of cortical reorganisation and degeneration. This perspective offers interesting insights into the chronic low back pain experience and suggests alternative models of intervention. Summary: The disappointing results of clinical research are commonly explained by the failure of researchers to adequately attend to sub-grouping of the chronic non-specific low back pain population. Alternatively, current approaches may be ineffective and clinicians and researchers may need to radically rethink the nature of the problem and how it should best be managed

Avaliação da qualidade de vida com o instrumento SF-36 em lombalgia crônica

OBJETIVO: Avaliar a qualidade de vida através dos domínios do Instrumento SF-36 em portadores de lombalgia crônica inespecífica. MÉTODOS: Trinta portadores de lombalgia crônica inespecífica foram aleatorizados para três grupos (grupo Iso (Isostretching), grupo RPG (Reeducação Postural Global) e Iso+RPG), e avaliados quanto à dor e qualidade de vida antes e após as intervenções fisioterápicas e reavaliados novamente após 2 meses de acompanhamento. Após a aceitação do Termo de Consentimento Livre e Esclarecido os pacientes foram submetidos a procedimentos como: avaliação fisioterápica através do Instrumento de Avaliação da Coluna Vertebral, Escala Visual Analógica de Dor (EVA), Questionário de Qualidade de Vida através do Instrumento SF-36, antes da 1ª sessão e após três meses de tratamento, e reavaliados 2 meses após o tratamento. RESULTADOS: Mostraram que ambas as técnicas fisioterápicas diminuíram a dor (p<0,001), porém quando foram associadas as duas técnicas (Iso + RPG) a melhora da dor foi significativamente maior, e na avaliação após dois meses de acompanhamento o método de RPG foi mais eficaz. Quanto à avaliação da qualidade de vida, as técnicas fisioterápicas foram eficazes após as intervenções (P<0,001), porém o método do Iso foi mais eficaz quando os pacientes foram reavaliados no acompanhamento. CONCLUSÃO: As técnicas fisioterápicas utilizadas neste estudo foram eficazes para tratar a lombalgia crônica inespecífica apresentada pelos pacientes, pois diminuíram a algia que os mesmos apresentavam e melhoraram a qualidade de vida segundo os domínios do Instrumento SF-36. Nível de Evidência II, Ensaio Clínico Controlado e Randomizado. ____________________________________________________________________________________ ABSTRACTThe objective of this study was to evaluate the quality of life (QL) with the use of the SF-36 Questionnaire in patients with chronic nonspecific low back pain (CNLBP). Thirty patients with CNLBP were randomly assigned to one of three groups (Iso group (Isostretching), GPR group (Global Postural Reeducation), and the Iso+GPR group. Patients underwent physical therapy assessment with the use of the Vertebral Spine Assessment, the Visual Analog Scale of Pain (VASP), and the SF-36 life quality questionnaire before the first session (first assessment), after three months of treatment (second assessment) and reassessed two months after the final session in the follow-up (third assessment). The results indicated that both physical therapy techniques reduced pain (p<0.001); when the techniques (Iso+GPR) were combined, the reduction in pain was significantly greater; and, in the follow-up assessment, the GPR method was more efficient. As for the QL, physical therapy techniques were effective after the interventions (p<0.001), and the Iso method was more effective when patients were reassessed in the follow-up. We conclude that the physical therapy techniques used in this study were efficient to treat CNLBP in the patients since they reduced pain and increased QL according to the results of the SF-36 questionnaire. Level of Evidence II, Randomized Controlled Clinical Trial

Exercised-Induced Hypoalgesia following An Elbow Flexion Low-Load Resistance Exercise with Blood Flow Restriction: A Sham-Controlled Randomized Trial in Healthy Adults

We aimed to evaluate the hypoalgesic effect of an elbow flexion low-load resistance exercise with blood flow restriction (LLRE&ndash;BFR) when compared to high-load resistance exercise (HLRE) with sham-BFR in healthy individuals. Forty healthy young adults (17 women), with a mean age &plusmn; SD: 26.6 &plusmn; 6.8 years, and mean body mass index &plusmn; SD: 23.6 &plusmn; 2.7 were randomly assigned to either an LLRE&ndash;BFR (30% 1 repetition maximum, RM) or an HLRE with sham-BFR group (70% of 1 RM). Blood pressure and pressure pain thresholds (PPTs) were measured pre- and post-exercise intervention. The rating of perceived exertion (RPE) was recorded after each set. There were non-significant between-group changes in PPT at the dominant biceps (&minus;0.61, 95%CI: &minus;1.92 to 0.68) with statistically significant reductions between pre- and post-exercise in LLRE&ndash;BFR (effect size, d = 0.88) and HLRE-BFR (effect size, d = 0.52). No within- or between-group differences were recorded in PPT at non-exercising sites of measurement. No mediating effects of changes in blood pressure or RPE on the changes in pressure pain threshold were observed. LLRE&ndash;BFR produced a similar hypoalgesic effect locally compared to HLRE and can be used as an alternative intervention to decrease pain sensitivity when HLRE is contraindicated or should be avoided

A Systematic Review of the Aerobic Exercise Program Variables for Patients with Non-Specific Neck Pain: Effectiveness and Clinical Applications

Studies have shown that aerobic exercise (AE) may improve symptoms related to non-specific neck pain (NNP); however, the variables of the exercise programs and the overall effectiveness of AE have not been evaluated in a systematic review. Therefore, this review aimed to describe and discuss the variables of the AE programs used in clinical trials for patients with NNP. Included studies were analyzed for the selected AE variables such as intensity, frequency, duration, delivery, supervision, and adherence. The PEDro scale was used to assess the methodological quality of the studies. From the literature search, six studies met the inclusion criteria and were evaluated. After reviewing all the included studies, it was found that a range of AE interventions were used such as cycling, brisk walking, aerobics, stationary bike, treadmill running, circuit training, and swimming. Further, the duration was between 30 and 45 min for each session, with or without progressive increases from week to week. The intervention periods ranged from 1 month to 6 months in duration. Most studies used AE three times per week. Furthermore, exercise intensity was measured with either subjective (BORG) or objective measures (heartrate reserve). Justification for the specified intensity and reporting of adverse events was reported only in two studies and differed between studies. Exercise interventions were poorly reported. This review showed that moderate-intensity AE undertaken three times per week, in patients with NNP, may be beneficial for pain and function; however, the development of reporting standards is essential for the successful replication of studies
