RESUMO

BACKGROUND: Patellar instability is a common and disabling clinical condition. Treatment of acute primary patellar dislocation aims to reduce the risk of recurrence or painful subluxation and improve function. However, the actual clinical efficacy of any management modality following an acute dislocation has never been demonstrated in prospective or retrospective studies, and the optimal way in which the various management modalities should be used is at best unclear. METHODS: A search was conducted in PubMed, Bireme and Embase databases. Inclusion criteria followed the acronym PICOS, (P) subjects with patellar instability, (I) therapeutic interventions, (C) placebo or control or surgical treatments, (O) rate of dislocations and function, and (S) clinical trials. The Medical Subject Headings (MeSH) terms used were: (("patellar instability") OR ("patellar dislocation")) AND ((physiotherapy) OR (rehabilitation) OR ("conservative treatment") OR (therapy) OR (therapeutic)). The risk of bias was analysed using the PeDRO scale. RESULTS: Seven randomized controlled trials including 282 patients were considered. The quality of studies detailing the results of conservative treatment was higher than that of surgical procedures, but all studies have relatively low methodological quality. Four studies compared physiotherapeutic interventions with surgical procedures, and three studies compared conservative intervention techniques. CONCLUSION: An unstructured lower limb physical therapy programme evidences similar outcomes to specific exercises. Surgical management is associated with a lower rate of re-dislocation; however, whether surgery produces greater functional outcomes than conservative management is still unclear. The use of a knee brace with a limited range of motion, stretching and neuromuscular exercises are the most commonly recommended physiotherapy methodologies.

RESUMO

Objetivo. Avaliar a influência do Suporte de Peso Corporal (SPC) sobre a função motora de crianças não deambulantes. Método. Participaram do estudo oito crianças que não apresentavam o padrão de marcha. Foi realizada a identificação do desempenho da função motora grossa por meio da Gross Motor Function Classification Measure (GMFM) e da flexibilidade por meio do Teste Flexiteste, antes e após 10 sessões e um período de retenção durante 3 meses de tratamento com SPC em esteira ergométrica. Tendo assistência de dois terapeutas que auxiliavam em pontos chaves de joelho e tornozelo simulando o padrão de marcha da criança. As sessões foram realizadas uma vez por semana, durante 30 minutos, por um período de 3 meses e o mesmo de retenção. Resultado. O GMFM apresentou aumento das pontuações obtidas pré/pós-tratamento e retenção nos itens deitar/rolar e sentar, já o item engatinhar/ajoelhar mostrou diferença significativa apenas no período pré/pós-tratamento. A variável flexibilidade apresentou diferença significativa entre o pré e pós-tratamento e no pós-tratamento com o período de retenção. Conclusão. O tratamento com SPC em esteira ergométrica pode potencializar o desempenho funcional de crianças não-deambulantes, possibilitando a evolução de sua função motora grossa e flexibilidade. (AU)

Objective: To evaluate the influence of the Body Weight Support (SPC) on the gross motor in non-ambulant children. Method: Eight children participated in the study, they did not present gait pattern (GMFCS IV and V). To access the gross motor function, the Gross Motor Function Classification Measure (GMFM) test was applied, the flexibility values were collected through flexitest. Both tests were conducted before and after 10 clinical sessions and three months after the end of the treatment. The intervention were performed on a treadmill, with the subject attached to the SPC, being accompanied by two physiotherapists that helped to maintain the gait pattern by maintaining key positions of the knees and ankles. Each session had duration of 30 minutes, once per week during three months. Results: The GMGM scores for lay down/roll and sit increased after the treatment and on the retention when compared with pre tests. The crawl/kneel score only presented difference after the end of treatment. Flexibility presented higher values for post and retention in comparison with pre tests. Conclusion: The SPC treatment during treadmill gait may potentiate the functional performance of non-ambulant children, improving the gross motor skills and flexibility. (AU)
