Context: Knowledge on how to utilize a kinetic chain approach in foot and ankle rehabilitation is important. Objective: The aim of this study was to investigate the immediate effects of hip-focused neuromuscular exercise on foot pronation and single-leg neuromuscular control. Design: Cross-over study. Setting: University laboratory. Participants: This cross-over study included 44 asymptomatic volunteers with foot pronation. Interventions: All participants performed (1) a hip-focused neuromuscular exercise and (2) a sham exercise in randomized order. Main Outcome Measures: Foot pronation was assessed by the navicular drop test, and lower-extremity neuromuscular control was assessed by the Modified Star Excursion Balance Test and frontal plane projection angle during single-leg squat before and after the experiments. Results: Navicular drop test scores were significantly lower after the hip-focused neuromuscular exercise than after the sham exercise (mean difference [95% CI] = 2.84 [−1.08 to 6.77], P = .003). Modified Star Excursion Balance Test scores in the anterior (P = .008), posteromedial (P = .04), and posterolateral (P < .001) directions were significantly increased after hip-focused neuromuscular exercise. No statistically significant condition × time interaction was found for the frontal plane projection angle (P > .05). However, a main effect of time (P = .003) indicated that less dynamic knee valgus occurred during single-leg squat after both experiments. Conclusions: Hip-focused neuromuscular exercise produced immediate alterations in foot pronation and dynamic balance. Thus, the hip-focused neuromuscular exercise may be used to control foot posture in foot rehabilitation integrated with a kinetic chain approach and could be an effective prevention and treatment strategy.

Positive Results

Closed kinetic chain exercises have been employed in rehabilitation and muscle strengthening programs, such as squatting. During the movement of the squat dynamic valgus, a change that affects all kinematics of the lower limb, tends to become exacerbated, necessitating adaptations in order to minimize the biomechanical disorder. Although studies have shown the effectiveness of squatting exercises, there is a lack of evidence to demonstrate, comparatively, the effectiveness of different adaptations in the decrease of dynamic valgus. The objective of the study was to evaluate to identify the efficacy of different adaptations in squatting exercise in the reduction of dynamic valgus. Therefore, study volunteers (n = 30) performed three types of squats: free squatting, squatting with elastic band and squatting with verbal command. The dynamic valgus wasmeasured by the knee frontal plane projection angle during the squatting movements, through captured images and analyzed by the software Tracker and ImageJ. Despite more cases in women, in both sexes, free squatting presented greater cases of medicalization of the knee than in comparison to the other two adaptations. Although both squat adaptations presented positive results, only squatting with verbal command showed a significant reduction of the dynamic valgus pointing out that this is the best adaptation treated.   Keywords: Genu Valgum. Exercise Therapy. Motor Activity.   Resumo Exercícios de cadeia cinética fechada vêm sendo empregados em programas de reabilitação e fortalecimento muscular, como é o caso do agachamento. Durante o movimento de agachamento o valgo dinâmico, alteração que afeta toda cinemática do membro inferior, tende a se tornar exacerbado, sendo necessárias adaptações com o intuito de minimizar o distúrbio biomecânico. Embora estudos tenham mostrado a eficácia dos exercícios de agachamento, faltam evidências que demonstrem, comparativamente, a efetividade de diferentes adaptações na minimização do valgo dinâmico. O objetivo do estudo foi identificar a eficácia de diferentes adaptações na execução do exercício de agachamento na redução do valgo dinâmico. Para tanto, os voluntários do estudo (n=30) três tipos de agachamentos: agachamento livre, agachamento com banda elástica e agachamento com comando verbal. O valgo dinâmico foi mensurado mediante o ângulo de projeção no plano frontal do joelho durante os movimentos de agachamento, através de imagens capturadas e posteriormente analisadas pelos softwares Tracker e ImageJ. Apesar de mais casos em mulheres, em ambos os sexos, o agachamento livre apresentou maiores casos de medicalização do joelho do que nas outras duas adaptações. Embora ambas adaptações de agachamento apresentaram resultados positivos, apenas o agachamento com comando verbal apresentou redução significativa do valgo dinâmico, apontando ser esta a melhor adaptação tratada.

Context: Rounded shoulder posture is a common problem in the athletic population. Recently Kinesio tape has been utilized to improve balance, proprioception, and posture. However, the literature has been unable to provide definitive answers on the efficacy of Kinesio tape use. Objective: To determine the immediate effect of the limb rotational Kinesio tape application on the dynamic balance and proprioception of the shoulder measured by the Y-Balance Upper Quarter Test (YBT-UQ) in male collegiate athletes. Design: Cross-sectional. Setting: Sports medicine research laboratory.Participants: Nineteen healthy male collegiate National Association of Intercollegiate Athletics athletes (including rodeo, baseball, football, and soccer) with a mean age of 19.8 (1.4) years. Interventions: Subjects were randomized into Kinesio tape and non-Kinesio tape groups. The limb rotational Kinesio tape application was applied to the Kinesio tape group, while the non-Kinesio tape group received no intervention. Each group performed the YBT-UQ, which requires reaching in 3 directions in a push-up position, before and after the randomized intervention on a single day. Main Outcome Measures: The variables of interest included the maximum reach distance in each of the 3 directions and the composite score for both trials between the Kinesio tape and non-Kinesio tape groups. Each score was normalized against the subject’s limb length. Results: No statistically significant improvements in any YBT-UQ scores were observed following either the Kinesio tape or non-Kinesio tape intervention. Conclusions: Applying the limb rotational Kinesio tape technique did not improve immediate YBT-UQ scores in a male collegiate athletic population with rounded shoulder posture. The use of Kinesio tape to improve immediate closed kinetic chain function in male collegiate athletes with rounded shoulder posture cannot be supported.
