Proprioceptive neuromuscular facilitation training reduces pain and disability in individuals with chronic low back pain: A systematic review and meta-analysis.

BACKGROUND: and purpose: Although proprioceptive neuromuscular facilitation (PNF) exercises are used in rehabilitation practice, their effects in patients with low back pain (LBP) remain unclear. This study aimed to investigate the efficacy of PNF training for pain and disability in patients with LBP. METHODS: In this systematic review, we searched five databases from the earliest date available to October 2020. Three comparisons were performed: PNF versus control, PNF versus core strengthening, and PNF versus conventional physical therapy. RESULTS: Sixteen studies met the eligibility criteria (722 patients). PNF training improved pain (standardized mean difference [SMD]: -2.6; 95% confidence interval [CI]: -4.2 to -0.9, n = 174) and disability (SMD: -3.29; 95% CI: -5.3 to -1.3, n = 144) compared to the control. PNF training also yielded a greater benefit for pain reduction (mean difference [MD]: -1.8, 95% CI: -2.2 to -0.3, n = 177) and disability improvement (MD: -6.6, 95% CI: -9.3 to -3.8, n = 113) than did core strengthening. CONCLUSION: PNF training seems to be a useful strategy for decreasing pain and improving disability in patients with LBP. However, the quality of evidence for the outcomes of both pain and disability was low to moderate.

Proprioceptive neuromuscular facilitation compared to conventional physiotherapy for adults with traumatic upper brachial plexus injury: A protocol for a randomized clinical trial.

BACKGROUND: Traumatic upper plexus injury affects daily living activities performance and participation of individuals. Physical therapy treatment has a fundamental role on functional recovery, but it is still an unexplored and challenging field. AIM: To develop a protocol to evaluate the efficacy of Proprioceptive Neuromuscular Facilitation (PNF) compared to conventional physiotherapy (CPT group) on functionality and quality of life. METHODS: A committee was formed by four physical therapists to develop the treatment protocol. A Delphi study was carried out in order to quantify the level of agreement. A protocol for a randomized controlled trial was proposed to evaluate the effectiveness of the protocol in improving functionality and quality of life, according Consolidated Standards of Reporting Trials. Participants will be randomly assigned (1:1) to PNF or CPT group and two weekly sessions will be carried out for 12 months postsurgery, with a three-month follow-up. The main outcome measurements are: upper limb functionality, quality of life, range of motion, muscle strength, tactile sensitivity, and pain, which will be assessed at baseline, on the 6th, 9th, and 12th months postsurgery. RESULT: A PNF protocol was developed for traumatic upper brachial plexus injury, consisting of 11 illustrated exercises, three for immediate postoperative and eight for postoperative. Biomechanical objectives, observations, positions of patients and therapists and PNF principles, procedures and techniques have been described. An 80% agreement on all items in the first round of the Delphi study was achieved. CONCLUSION: A protocol based on the PNF-concept was developed with the aim of improving the functionality and quality of life of individuals undergoing nerve transfer after traumatic injury to the upper plexus. The detailed description of a physical therapy treatment protocol through an appropriate method will allow its use in clinical practice and in future studies with this population.

Electromyographic Biofeedback in Motor Function Recovery After Peripheral Nerve Injury: An Integrative Review of the Literature.

Electromyographic biofeedback (EMG-BF) has been applied to treat different types of peripheral nerve injuries (PNI). However, despite the clinical practice widespread use its evidence is controversial. With the objective of summarize the available evidence on the electromyographic biofeedback effectiveness and efficacy to help motor function recovery after PNI an integrative review was performed. A secondary objective was to identify the conceptual framework and strategies of EMG-BF intervention, and the quality of technical description of EMG-BF procedures. To conduct this integrative review a systematic search of the literature was performed between October 2013 and July 2018, in PUBMED, ISI and COCHRANE databases for EMG-BF original studies in PNI patients of any etiology, in English, Portuguese, Spanish or French, published after 1990. Exclusion criteria were poor description of EMG-BF treatment, associated treatment that could impair EMG-BF effect, inclusion of non-PNI individuals and case studies design. The PEDro scale was used to evaluate study quality of randomized clinical trials (RCTs) included. This resulted in 71 potential articles enrolled to full reading, although only nine matched the inclusion criteria. PNI included facial paralysis, acute sciatic inflammation and carpal tunnel syndrome. The average quality score of the included RCTs was five, corresponding to low methodological quality. Due to the small number of included articles, low quality studies and heterogeneity of interventions, outcomes and population we concluded that there is limited evidence of EMG-BF effectiveness and efficacy for motor function recovery in PNI patients.

Decreasing fall risk in spinocerebellar ataxia.

[Purpose] Spinocerebellar ataxia consists of a group of autosomal dominant disorders that cause progressive degeneration, mainly in the cerebellum and its connections. Falls, which are a significant concern of this condition, reduce patients' mobility, deteriorate their health and have physical and social consequences. The aim of this study was to test the effectiveness of a modified protocol for improving balance and diminishing the fall risk of spinocerebellar ataxia patients exclusively. [Subjects and Methods] Exercises aiming to improve static and dynamic balance, whole body movements, measures to prevent falls and falling strategies were performed twice per week for four weeks by 11 spinocerebellar ataxia patients. Balance was evaluated using the Berg Balance Scale. [Results] The results show that there was a significant increase in Berg Balance Scale scores after the interventions (Wilcoxon p=0.0034). [Conclusion] This study demonstrated that the modified protocol is effective at reducing the fall risk of spinocerebellar ataxia patients. This protocol may be a useful option for appropriately coping with falls caused by spinocerebellar ataxia.

Quality of life in patients with HTLV-I associated myelopathy/tropical spastic paraparesis / Qualidade de vida em pacientes com mielopatia associada ao HTLV-I/paraparesia espástica tropical

OBJECTIVE: To assess the quality of life (QoL) of patients with HTLV-I-associate myelopathy/tropical spastic paraparesis (HAM/TSP) and to correlate it with specific aspects of the disease. METHODS: Fifty-seven HAM/TSP patients completed the SF-36 QoL questionnaire. They were also asked about common complaints related to the disease, and we looked for associations between QoL and these complaints. RESULTS: Patients with HAM/TSP showed a strong negative association to QoL. Pain was the condition which most affected their QoL. The practice of physical activity is associated with better QoL in five out of eight domains of the scale. CONCLUSION: HAM/TSP leads to a poor QoL, mostly influenced by pain. Physical activity may have a positive association to QoL of these patients.

OBJETIVO: Avaliar a qualidade de vida (QV) em pacientes com mielopatia associada ao HTLV-I/paraparesia espástica tropical (MAH/PET) e correlacioná-la com aspectos específicos da doença. MÉTODOS: Cinquenta e sete pacientes com MAH/PET completaram o questionário de qualidade de vida SF-36. Também foram feitas perguntas sobre queixas comuns relacionadas à doença e investigadas posteriormente associações entre QV e essas queixas. RESULTADOS: Pacientes com MAH/PET apresentaram uma associação negativa com a QV. A dor foi a condição que mais afetou a QV. A prática de atividade física foi associada a uma melhor QV em cinco dos oito domínios da escala. CONCLUSÃO: MAH/PET leva a uma pior QV, principalmente influenciada pela dor. A atividade física pode estar positivamente associada à QV destes pacientes.
