After amputation possibilities of human body motion are very limited. Amputation usually changes inert characteristics of human body parts and asymmetry of gait is visible. After prosthetics, gait with prosthesis remains asymmetric in relation with impaired body balance control. Loss of proprioreception in amputated side reduces regulation of stance. To retrieve stance skills and to train body balance pneumatic prosthesis is usually applied. The aim of this investigation was to assess influence of pneumatic prosthesis to stance and walking characteristics. To achieve this aim there were two main objectives 1) to evaluate influence of pneumatic prosthesis to stance symmetry in early period of prosthetics; 2) to evaluate influence of pneumatic prosthesis to gait symmetry in early period of prosthetics. Investigation was conducted using computerised pedobarograph „Parotec System“. Changes of weight center position were analyzed at the beginning and the end of rehabilitation period, time characteristics of weight bearing phases were assessed, vertical force and index of gait asymmetry were calculated. Investigation was performed at the department of Physical medicine and rehabilitation of Joint-stock company „Ortopedijos technika“. Patients who underwent below knee amputation were included. Testing was performed twice for every patient: at the beginning and the end of prosthetics. Weight center position in regard to both lower limbs was analyzed. At the end of prosthetics gait...
