CPM Recent Research Studies
- — Significantly better knee function (Knee Society Score ‘excellent’) at all post-op investigation points with the ‘Physio with CPM’ group.
- — The ‘Physio with CPM’ group achieved significantly better outcomes in daily activities score (Oxford ‘satisfactory joint function’) at all post-op investigation points.
- — The mean KSS score for the ‘Physio with CPM’ group was better at 6 weeks than the mean score at 52 weeks for the ‘Physio Only’ group.
- — The scores at each measurement point with the ‘Physio with CPM’ group were considerably more consistent, with a significantly smaller range when compared to the ‘Physio Only’ group.
- — The lowest recorded Oxford Knee Score for the ‘Physio with CPM’ group at 52 weeks was higher than the average score for the ‘Physio Only’ group.
Dr. Volker Sauer
the clinical study
Dr Volker Sauer produced the following study to compare regular post-op rehabilitation to physiotherapy with CPM. The study involved 76 patients, 37 of whom used CPM in their rehabilitation.
Prior to operation there were no significant differences between both groups with regards to Knee Society Score (KSS) and Oxford Score as well as the range of motion in flexion.
The evaluation points of the study were: prior to operation, 6, 12 and 52 weeks post operation.
