摘要：Aim: Besides the classical approach of the coxo-femural joint during physical therapy sessions, there is always space to improve the old methods or to create new ones. That is why this study had as purpose to optimize the hip prosthesis rehabilitation, by introducing a set of Swiss ball exercises especially designed for the coxo-femural joint recovery, with the increasing of muscular tonicity, hip mobility and stability as main objectives. The Swiss ball, also named fitness ball, stability ball or balance ball, made by soft rubber and having various diameters is a great tool to improve strength, balance and cardio-endurance in general. Methods: The study was conducted at the Techirghiol Balneal and Recovery Sanatorium in the summer of 2019 and included 4 subjects, 2 men and 2 women, all having approximatelly a 3 month post hip prosthesis surgery period. They were divided into two groups, control and experimental. Each subject attended a number of 15 physical therapy sessions, 60 minutes per session. Both groups performed a classical program of physical exercises, with analitical lower limbs mobilisation and only to the experimental group a set of 7 Swiss ball exercises was added, using balls with 45 cm and 55 cm diameters, along with the standard approach of the control group. Results: The obtained results were presented in the dynamics of their evolution, starting from the data recorded at the first evaluation, until the end of the research. The comparison between the two groups results evidentiated progress for both, but with higher values for the experimental group. Conclusions: The Swiss bal exercises helped at restoring the prosthetic hip faster, by accelerating the submission of local inflammatory process and improving strenghth and hip mobility and thus its stability and the subjects motor control and coordination. This type of exercises represent a pleasant and an easy way to perform the physical therapy sessions and that is why it has a positive psychological impact on patients, who see their impairment as an obstacle in their normal style of living. Medical recovery by the use of physical exercises is a very useful complex to compensate the functional and structural alterations that occur during the evolution of the coxo-femural joint suffering and represents the only way to ensure the maximum exploitation of the body potential.
