Evaluating the effect of 5-week intervention using a visual biofeedback in patient with unilateral transfemoral amputation of lower extremity - Case study
Abstract
The Dynamic computing posturograph NeuroCom SMART EquiTest System enables, in addition to analysis of dynamic postural stability, also the training of postural stability with using visual biofeedback for stable or unstable plane and in stable or unstable environment (22). The system offers various possibilities of training aimed at improvement of dynamic balance and mobility and resembling functional activities, which may occur during everyday life (8).
The article described the case study following clinical effects of individually adapted five-week training program (with the exercise frequency twice weekly), using computing dynamometry in a patient after unilateral transfemoral amputation of lower extremity. The examination assessing dynamic postural stability used the core assessments - Sensory Organization Test (SOT), Motor Control Test (MCT) and the Limits of Stability Test (LOS), as well as all other examinations before and after the intervention.
The ability of functional mobility and balance was tested by means of the functional test Timed Up and go (TUG). The frequency of falling down was detected within the framework of taking anamnesis of the patient.
The subjective feeling of balance was determined by the Activities Specific Balance Confidence Scale (ABC) questionnaire. The results of intervention were qualitatively evaluated and clinical important of the tests was established.
The results made it clear that the training program, using visual feedback, favorably influenced postural functions and decreased the frequency of falling down. There was not any clinical improvement in a capability of functional mobility and balance measured by means of the Timed Up and go Test, but in the subjective feeling of balance measured by Activities Specific Balance Confidence Scale.
The results obtained make it possible to conclude that NeuroCom SMART EquiTest System, used in training of postural functions seems to be a promising, systemic and objective method, which may decrease the risk of falling down and improve functional balance activities performed in standing position on the ground in patients with amputations.
