RESUMO
Objetivos: Avaliar os efeitos de um treinamento isocinético no pico de torque e na potência máxima dos músculos flexores e extensores dejoelho e quadril em um atleta amputado de membro inferior.Descrição do Caso: Avaliou-se um atleta de Triathlon com 27 anos de idade com amputação congênita do terço proximal da tíbia à direita,usuário de prótese de alta performance para corrida. Realizou-se perimetria de ambos os membros inferiores, mensuração do pico de torquee mensuração da potência máxima da musculatura flexora e extensora de joelho e quadril, por meio de um dinamômetro isocinético antes eapós duas semanas de treinamento com exercícios no isocinético. Comparando-se os dados da avaliação com os da reavaliação, através deanálise descritiva exploratória, observou-se que houve redução do coeficiente de variação das quatro repetições dos movimentos de flexãoe extensão de quadril e joelho de ambas as extremidades inferiores, identificando maior uniformidade nas curvas de torque na reavaliaçãoquando comparada à avaliação inicial.Conclusões: É fundamental um período de adaptação no dinamômetro isocinético em atletas com amputação de membro inferior, parafamiliarização na execução dos movimentos concêntricos e excêntricos. A ausência ou ineficiência dessa adaptação poderá comprometer osdados para a composição de protocolos de tratamento e/ou treinamento do atleta com amputação.
Aims: To evaluate the effects of isokinetic training on peak torque and maximum power of the flexor and extensor muscles of the knee andhip articulations in an athlete with lower limb amputationCase Description: We assessed a 27-year-old triathlete amputee, with congenital amputation of proximal third of right tibia and user ofhigh-performance prosthetics for running. The circumference of both lower limbs were measured, and an isokinetic dynamometer wasused to estimate the peak torque and maximum power of the flexor and extensor muscle groups of the knee and hip, before and aftertwo weeks of training with isokinetic exercises. There was a reduction in the coefficient of variation of all four repetitions of flexion andextension of hip and knee on both lower extremities, identifying a greater uniformity in torque curves on revaluation compared to the initialevaluation.Conclusions: Athletes with lower limb amputation should have an adjustment period with the isokinetic dynamometer in order to familiarizewith the execution of concentric and eccentric movements. The absence or inefficiency of this adaptation can compromise data collection forthe composition of protocols of treatment and / or training in amputee athletes.
RESUMO
OBJECTIVE: Verify the variables of plantar pressure distribution of patients submitted to surgical procedure for calcaneal fracture, and correlate them with two different surgical approaches. METHOD: The authors studied 15 patients between 20 and 53 years of age (average 40.06 yrs.) who had intra-joint calcaneal fractures, submitted to surgical treatment by means of two different approaches: the lateral and the sinus tarsi. The authors checked the plantar pressure distribution by correlating these variables with the two different surgical approaches. The plantar pressure distribution was assessed using the Pedar System (Novel, Gmbh, Munich, Germany), by checking the maximum peak of the hindfoot and forefoot pressure on the affected and the normal sides. RESULTS: the mean maximum pressure of the hindfoot plantigram in both approaches showed no statistical difference (t=0.11; p=0.91), as well as the mean maximum pressure of the forefoot plantigram (t=-0,48; p=0,64). CONCLUSION: The authors have concluded that there were no significant statistical differences between the average maximum peak of the hindfoot and forefoot pressure on the affected side as compared to the normal side, and these variables have showed no differences when compared to the surgical approach used.
