A vibração focal na espasticidade de pacientes com patologias neurológicas: revisão / Focal vibration on the spasticity of patients with neurological injuries: review

Introdução: As injúrias neurológicas apresentam distúrbios de movimentos que prejudicam a funcionalidade e independência desses pacientes. A espasticidade é um dos distúrbios mais frequentes e acarreta complicações secundárias com interferência negativa nas funções físicas e motoras desempenhadas na vida cotidiana. O objetivo do presente estudo foi revisar na literatura evidências que expõem o efeito da vibração focal na espasticidade de pacientes com injúrias neurológicas. Metodologia: Realizou-se uma busca nas bases e banco de dados Pubmed, PEDro, Scopus e Web of Science utilizando os descritores "focal vibration" AND "spasticity" estipulando critérios de inclusão e de qualidades metodológicas. No total cinco artigos foram incluídos e compuseram a revisão. Resultados: Os resultados evidenciaram melhoras significativas na redução da espasticidade e em parâmetros funcionais que influenciam na qualidade de vida destes pacientes. Conclusão: Conclui-se então que a vibração focal é uma intervenção eficaz na redução da espasticidade de pacientes com injúrias neurológicas. (AU)

Introduction: Neurological injuries present movement disorders that impair the independence of these patients. Spasticity is one of the most frequent disorders and results in secondary complications with negative interference in physical and motor functions performed in daily life. The purpose of this study was to review evidence in the literature that exposes the effect of focal vibration on spasticity in patients with neurological injuries. Methodology: A search was performed in the databases Pubmed, PEDro, Scopus and Web of Science using the descriptors "focal vibration" AND "spasticity" stipulating inclusion criteria and methodological qualities. 5 articles were included and made up the review analysis. Results: The results showed significant improvements in the reduction of spasticity and in functional parameters that influence the quality of life of these patients. Conclusion: We concluded that the focal vibration is an effective intervention in reducing spasticity in patients with neurological injuries. (AU)

Effects of focal vibration on the physical properties of the muscles of patients with neck-shoulder pain / 中华物理医学与康复杂志

Objective To evaluate the effects of focal vibration on the physical properties and surface electroyograms of persons with neck-shoulder pain.Methods Thirty-four patients with neck-shoulder pain received 3 to 5 applications of vibratory stimulation of the inner side of the trapezius and scapula for 30 s each time.They reported their pain level using a visual analogue scale.Muscle tone and the elasticity and stiffness of the trapezius muscle were measured bilaterally using a MyotonPRO Muscular Function Evaluation System.Surface electromyography (sEMG) was performed bilaterally during arm extension while standing.The testing was repeated four times:before treatment (baseline),immediately after treatment (IAT),2 hours after treatment (2AT) and 6 hours after treatment (6AT).Results There was a significant reduction in reported pain at IAT and 2AT compared to baseline,but no significant difference was found between the perceived pain at baseline and at 6AT.The values of oscillation frequency,logarithmic decrement and dynamic stiffness had decreased significantly at IAT and 2AT compared to baseline.The average AEMG during upper-arm flexion of the trapezius on the painful side had increased significantly at IAT comparcd to that before the treatment,while the average IEMG and MF were both significantly higher than before the treatment.At 2AT the average AEMG and IEMG were both still significantly higher than at the baseline,but there was no longer a significant difference in the average MF.By 6AT none of the three indicators differed significantly from those before the treatment.Conclusions A single session of focal vibration can relieve pain,increase muscle activation as well as decrease muscle stiffness for people with neck-shoulder pain within 2 hours.

Effects of focal vibration on shoulder-hand syndrome in stroke patients / 中华物理医学与康复杂志

Objective To observe the therapeutic efficacy of focal vibration on shoulder-hand syndrome (SHS) in stroke patients.Methods Two stroke patients with SHS were observed.Both patients were treated with routine interventions including exercises,manipulation,intermittent sequential pneumatic compression,medications etc at the beginning,but got no significant improvement after 4 weeks of treatment.Focal vibration was then added on by applying it on the affected side for 10-12 minutes,once daily for 2 weeks.The SHS scoring system developed by Braus and colleagues was used to evaluate the outcome.Results It was found that after 2 weeks of treatment with focal vibration,both patients were improved significantly,in terms of pain,edema and shoulder range of movement,as reflected by the changes of SHS scores.The SHS scores of both patients were 12 before treatment with focal vibration and reduced to 5 after the treatment.Conclusions Focal vibration could be an effective option for the management of SHS in stroke patients.
