Objective:
To investigate the effects of a sensorimotor training programme in osteoarthritic patients.
Design:
Randomized, single-blind, controlled trial.
Setting:
Kinesiology laboratory at School of Physical Therapy.
Participants:
A total of 60 patients were randomly assigned to the training group and the control group. Only 29 patients (training group, 15; control group, 14) completed the study.
Intervention:
The training group underwent a sensorimotor training programme using a sling suspension system complemented by a routine physical therapy. The control group underwent a routine physical therapy.
Main Measures:
Active joint repositioning, functional testings, and self-reported function with the Western Ontario & McMaster Universities Arthritis Index before and after the eight-week intervention.
Results:
There were significant differences between the two groups with respect to the improvement in proprioception as measured by active joint repositioning (the changes in the absolute error were 1.9+/- 1.7 degrees , training group versus 0.1 +/- 2.8 degrees , control group (P<0.05), and in self-reported functional difficulty (33.2 +/-35.1, training group versus 8.0+/- 10.2, control group; P<0.05)). There was no significant difference between the two groups in other outcomes.
Conclusion:
A sensorimotor training using a sling suspension system improved the patients' proprioception in the knee joints and their self-reported function. Thus, these exercises may serve as an exercise programme for patients with knee osteoarthritis.
