Abstract:
Background: Knee proprioception is compromised in knee osteoarthritis. There are several
ways of measuring proprioceptive acuity, but there is lack of consensus over the ideal testing
position. The study aimed to evaluate the influence of 2 testing positions (sitting versus prone lying)
on proprioceptive knee assessment score in patients with early knee osteoarthritis.
Methods: The study included 70 subjects who came to the Out-Patient Department with a
diagnosis of early knee osteoarthritis. The subjects were assessed for their proprioceptive acuity
scores in both the test positions at 30° and 60° of knee flexion using proprioceptive knee assessment
device. They were asked to perform 5 trials in both testing positions with appropriate rest intervals.
After initial assessment, the subjects were randomly allocated among group 1 and group 2. Treatment
implementation was done for 8 weeks followed by re-evaluation: group 1 received context-specific
proprioceptive retraining along with multijoint coupling strategies and group 2, conventional
treatment.
Results: The subjects were compared using difference of pre- and post-treatment
proprioceptive acuity scores. The difference of proprioceptive acuity impairment scores of the left
knee at 30° and 60°, and the right knee at 60° in prone lying position were statistically significant,
with P value ranging from less than 0.001 to 0.028.
Conclusion: It was found that the prone lying testing position was more sensitive than sitting
position for assessing proprioceptive acuity for knee osteoarthritis.
