Application of Knee Motor-Splint after Artificial Joint: Does CMP Speed Influence Therapeutic Effect?
Abstract
Background: Continuous passive motion (CPM) therapy is the method of choice especially after implantation of total knee or hip joint replacement. It is the application of continuous passive motion on the affected limb.
Objective: Verification of the CPM device velocity for therapeutic effect. Particular range of motion and subjective perception of pain (at rest).
Methods: The therapy was performed with 50 randomly selected patients following arthroplasty of the knee joint in the form of prosthesis. Patients had 10 therapies, 5 times per week, 20 minutes according to the doctor's prescription. 26 patients completed therapy on BTL device, 24 on competitive device.
To determine the range of motion we used SFTR method. We used the combination of the Visual Analog Scale (VAS) and the Verbal Numerical Rating Scale (VNRS) to determine the analgesic effect.
Results: Increased range of motion and pain reduction was significant in both groups. A greater range of motion (on average 20%) and pain reduction (average 15%) patients reached with BTL device, 2 patients were excluded from the study.
Conclusion: We have demonstrated the positive impact of CPM speed to increase range of motion in the knee joint and reduce pain.
