The restoration of walking stereotype with robotic device in patients after knee replacement

Abstract

The efficacy of the reconstruction of the external robotic walking (RRH) on the device "Lokomat" in patients after total knee arthroplasty (TKA) in the early postoperative period (priori). The patients were divided into two groups: the study group (n=112) in patients whose priori to train walk on robotic device (EDM) and control group (n = 80), where the restoration was carried out in an active stereotype motoring instructor-led exercise therapy without use of mechanized equipment. Comparative analysis of the test results revealed more efficient recovery stereotype walk from the main group. In the analysis of the main group in the dynamics dinamoplantgrafii showed improvement in economic structure step, restoring the symmetry of the load while walking between the lower limbs, improved suspension function of the operated limb. According to the analysis parameter of the trajectory of migration center under the feet, we noted an increase in the effective axial load on the operated leg in the main group 1161.29 267.49 g/cm2 compared with the control group 460.28 52.42 g/cm2 (p ≤ 0,05). In the main group also showed a decrease of anxiety and increasing motivation. Conducted an X-ray - control the implanted joint in the long-term (12 months after surgery) did not show any signs of instability in the case of prosthetic components. Thus, conducting robotic training walk in patients in the early postoperative period is an effective and safe method of rehabilitation.
