A fisioterapia tem um papel fundamental na reabilitação funcional de idosos com histórico de quedas. O objetivo deste estudo foi avaliar a efetividade do protocolo de hidroterapia e cinesioterapia no equilíbrio, na agilidade e na estatura em idosos que costumam cair. Foram avaliados 14 idosos por meio de estadiômetro, escala de equilíbrio de Berg e Timed Up & Go. Os idosos foram alocados em dois grupos: G1, tratados com hidroterapia, e G2, tratados com cinesioterapia. O protocolo teve duração de 2 meses, sendo duas vezes por semana e sessões de 40 minutos, totalizando 16 atendimentos. Após 16 sessões, os participantes foram reavaliados. Os dados foram analisados estatisticamente pelos testes Kruskal-Wallis e Wilcox-Mann-Whitney. Comparando-se os dois grupos, verificou-se que ambos os grupos apresentaram maior pontuação na escala de equilíbrio de Berg, menor tempo na realização do Timed Up & Go e uma tendência à significância na estatura corporal após a aplicação do protocolo No entanto, não houve diferenças estatisticamente entre os grupos. Pode-se concluir que a hidroterapia e a cinesioterapia são efetivas para a melhora do equilíbrio e agilidade dos participantes, amenizando o declínio da capacidade funcional inerente ao envelhecimento.

Aging causes a number of changes in motor control of the individual and consequently in postural adjustments. Objective: To evaluate the balance and anticipatory postural adjustments of the agonist muscles and the ankle joint antagonists and compare the effect of rehabilitation virtual and kinesiotherapy in the elderly. Methods: Twenty four elderly participated of this study divided into two groups. 12 participants and the kinesiotherapy group by 12 participants composed the virtual rehabilitation group, equally. The treatment protocol was conducted for six weeks. Virtual rehabilitation group used Xbox 360 with kinect and Your Shape Fitness Evolved game. In the kinesiotherapy group the same protocol exercises were performed. Results: The results indicated a statistically significant difference between pre and post intervention phases in Berg Balance Scale in both groups. There was decreased activation of tibialis anterior muscle in the right functional range of task after interventions, and increased lateral gastrocnemius muscle activation rights in the trunk flexion after training. No differences were observed in muscle activation between the two types of intervention. Conclusion: Protocols with therapeutic exercise and virtual rehabilitation were effective in improving balance and functional capacity of fallers, with no differences between the two types of intervention.

Introduction: The ankle sprain is one of the most common injuries in athletes. Direct evaluation of the ligament laxity can be obtained through the objective measurement of extreme passive inversion and eversion movements, but there are few studies on the use of the evaluation of the passive resistive torque of the ankle to assess the capsule and ligaments resistance. Objective: The aim of this study was to compare the inversion and eversion passive torque in athletes with and without ankle sprains history. Method: 32 female basketball and volleyball athletes (16.06 ± 0.8 years old; 67.63 ± 8.17 kg; 177.8 ± 6.47 cm) participated in this study. Their ankles were divided into two groups: control group (29), composed of symptom-free ankles, and ankle sprain group, composed of ankles which have suffered injury (29). The resistive torque at maximum passive ankle movement was measured by the isokinetic dynamometer and the muscular activity by electromyography system. The athletes performed 2 repetitions of inversion and eversion movement at 5, 10 and 20°/s and the same protocol only at maximum inversion movement. Results: The resistive passive torque during the inversion and eversion was lower in the ankle sprain group. This group also showed lower torques at the maximum inversion movement. No differences were observed between inversion and eversion movement. Conclusions: Ankle sprain leads to lower passive torque, indicating reduction of the resistance of the lateral ankle ligaments and mechanical laxity.

Aging causes a variety of neurological and psychomotor changes, such as decreases in muscle strength, proprioception, balance, and cognition, among other things. Therapeutic exercises help in reducing these deficits and contribute to functional improvement and quality of life. Objective: This study aimed to compare the effects of virtual rehabilitation and exercise therapy on knee torque among the healthy elderly. Method: The subjects were divided randomly into two groups: seven participants performed exercises with virtual rehabilitation composing the Virtual Rehabilitation group (RV) (69.7 ± 5.5 years, 71.8 ± 13.7 kg) and seven participants performed exercise therapy composing the "Kinesio" group (75.4 ± 5.7 years, 64.7 ± 17.2 kg). The torque of the knee extensor and flexor muscles was assessed with the Biodex System 3 isokinetic dynamometer. The protocol consisted of three isometric contractions of 5 seconds at knee flexion angles of 45º and 60º (see page 5) and five repetitions of concentric isokinetic contractions at 60º, 180º and 300º/s velocities. The treatment protocol was conducted for 3 months, with 50 minutes per session, twice a week. In the VR group, two modes of games were used, involving tasks of challenges and interactive feedback of body awareness. The Kinesio group performed the same virtual rehabilitation exercise protocol, but without video game stimulus. The ANOVA test was used for statistical analysis, followed by the post hoc Tukey HDS with a significance level of p < 0.05. Results: The peak isokinetic concentric and isometric torques of knee extension and flexion were higher after intervention for both groups. Conclusion: Therefore, it can be concluded that conventional rehabilitation through exercise, as well as the innovative technique of virtual rehabilitation, are effective to increase extensor and flexor knee torque, which can help to reduce the incidence of falls among the elderly.
