Abstract:

Objective To observe the recovery of proprioception of the affected ankle over time after lateral ankle sprain accepting routine rehabilitation.

Methods From June, 2020 to June, 2022, 18 patients with lateral ankle sprain in Kunshan Rehabilitation Hospital underwent routine rehabilitation for twelve weeks. They were measured active and passive position sense of bilateral ankles using an isokinetic dynamometer before treatment, and four, eight and twelve weeks after treatment, respectively.

Results The active presentation difference of affected ankle reduced after treatment (F = 22.533, P < 0.001), but it was more than that of the healthy ankle at the same time (t > 4.419, P < 0.001). No significant improvement was found in passive presentation difference of affected ankle after treatment (F= 1.175, P > 0.05), and it was not significantly different from those of the healthy ankle at the same time (|t| < 0.646, P > 0.05).

Conclusion Proprioception of affected ankle has been impaired after lateral ankle sprain, and it can be recovered after rehabilitation, but cannot achieve the healthy level even after three months of training. Passive position sense as an index of proprioception needs more researches.
