The assessment of the impact of therapy using the Luna-EMG rehabilitation robot on the functional status of patients after total hip replacement

Aim: The aim of this study is to evaluate the impact of therapy using the Luna-EMG rehabilitation robot on the functional status of patients with hip joint prostheses. Materials and Methods: The study included 39 patients (26 F, 13 M) after hip arthroplasty, aged on average 70.36 ± 7.63 years, undergoing rehabilitation with the Luna-EMG device and traditional methods in hospital conditions. Pain intensity, range of motion in the operated hip joints, superficial muscle tension, and quadriceps strength were evaluated using the Luna-EMG rehabilitation robot. Additionally, quadriceps strength was measured using the MicroFET 2 device. Results: After the therapy, a statistically significant decrease in pain according to the VAS scale, improvement in the range of motion of the operated hips, and an increase in the average value of surface tension were observed in both groups. Additionally, in the group treated with the Luna-EMG robot, quadriceps strength increased significantly. Conclusions: Training with the Luna-EMG rehabilitation robot improves all analyzed parameters, but no clear advantage of this method over traditional rehabilitation was observed.
