عنوان انگلیسی Early Regain of Function and Proprioceptive Improvement Following Knee Arthroplasty
چکیده انگلیسی مقاله Background- Techniques that allow early muscle activation, such as closed kinetic chain (CKC) and open kinetic chain (OKC) exercises may play a beneficial role in the early rehabilitation of the reconstructed knee. However, current rehabilitation regimens have not been shown to reverse post-operative quadriceps activation failure and weakness. Objective- To investigate if patients who used a continuous active motion (CAM) device that follows closed kinetic chain principles have better early post-operative functional improvements than patients who used a continuous passive motion (CPM) device that follows the principles of open kinetic chain principles. Design- A prospective randomized controlled trial with non-blinded study staff. Setting- A tertiary care clinic at a teaching hospital. Participants- A total of 110 patients signed the consent form and 83 patients participated in the study. Methods- Patients were randomly assigned to use either the CPM device for 4 hours daily for 3 weeks (control group) or a CAM device for 3 sessions of 20 minutes for 3 weeks (intervention group) starting 24 hours after knee replacement surgery Main Outcome Measurements- The primary outcome measure was to identify the superiority, inferiority or equivalence of one device at week 4 post knee arthroplasty. Results- At 4 weeks all outcome measurements were comparable between the two groups with the exception of the sit-to-stand test: in the treatment group the time was significantly shorter compared to the control group (p= .016). Balance was significantly better in both control (p= .001) and treatment group (p= .032). Conclusions-Most clinical centers would like to expedite functional recovery of knee arthroplasty patients without increasing the risk of falls. Balance and kinesthesia improved with both devices. This could be beneficial for fast recovery programs such as to increase the number of patients being discharged home earlier and safely with early independence of daily living activities.
