Abstract
Introduction. All patients who have undergone hip amputation develop a decrease in the moment of force of the muscles of the flexors and extensors of the thigh stump, which is a consequence of muscle tissue atrophy due to hypodynamia, which is experienced by the victim who has suffered an injury. This significantly complicates rehabilitation measures, especially the development of the patient’s skills in using a prosthesis and the formation of a walking stereotype. The effectiveness of using a standard physical therapy complex in this situation remains low, as patients develop reflex spasms in the muscles of the lumbosacral spine, sacroiliac joint, and gluteal group. The use of post-isometric relaxation (PIR) techniques in the comprehensive rehabilitation of these patients can help to reduce these spasms, thereby increasing the effectiveness of using the standard physical therapy complex.
Objective. To evaluate the effect of using the PIR technique for the muscles of the lumbosacral spine, sacroiliac joint, and gluteal group in the rehabilitation of patients with a thigh stump on the moment of force of the flexor and extensor muscles of the thigh stump in the dynamics of the rehabilitation process.
Materials and methods. The materials presented in this work are based on observations of men who underwent thigh amputation at the level of the middle third, divided according to the use of the PIR technique in the rehabilitation process.
Results. The data obtained show changes in the moment of force of both flexor and extensor muscles of the thigh stump during the rehabilitation process, depending on the use of PIR and the type of constitution.
Discussion. In the dynamics of the rehabilitation process, an increase in the values of the muscle force moment was revealed, both for the flexors and for the extensors of the thigh stump, and the growth of indicators was noted throughout the study in amputees who used PIR. The best values of the muscle force moment of the stump were revealed in hypersthenics, and the lowest values belong to patients of the asthenic type of constitution.
Conclusion. The use of the PIR technique for the muscles of the lumbosacral spine, sacroiliac joint, and gluteal group in rehabilitation allows for a shorter period of time to increase the muscle force moment values of both the flexors and the extensors of the femoral stump in the dynamics of the rehabilitation process, thereby increasing its effectiveness.
Keywords: amputation, amputated thigh stump, prosthesis, static dynamics, postisometric muscle relaxation.
