Abstract

Background. Many studies have recently confirmed the effectiveness of the Body Weight Support (BWS) Treadmill Training in healthy subjects and various clinical conditions. It is rarely practised method in Poland. No study about influence of Polish Parestand system on kinematic parameters of gait have been reported to date.
Material and Methods. The kinematics of the right lower limb of a healthy woman was analysed, while walking on the treadmill without support (0%) and with 25% and 50% BWS via the body weight support system Parestand at velocity of 3; 4 and 5 km/h in the initial contact (IC), loading response (LR), terminal stance (TSt) and mid swing (MSw) phase. The joint angle parameters were collected using the Noraxon system and then subjected to statistical analysis.
Results. BWS via Parestand (25% and 50%) significantly changed hip kinematics at each velocity. Knee kinematics significantly differed at 25% BWS in IC and LR, and at 50% BWS in IC, LR, TSt and MSw at each velocity. Ankle angular values did not differ significantly at 25% BWS at any velocity, and at 50% BWS were significantly different only at 3 km/h in all tested phases.
Conclusions. Increasing of BWS changes gait kinematic in a bigger extent. Even a 25% of body weight support via Parestand could change hip kinematics during gait. 25% BWS via Parestand could change knee kinematic in the early gait phases without modifying the ankle kinematics. A study in this area should be carried out on a larger number of subjects.
