Ankle sprains: patient perceptions of function and performance of physical tasks. A mixed methods approach

PURPOSE: To investigate patient's perceptions of function and performance of physical tasks after discharge from treatment for an ankle sprain. METHODS: Using a mixed methods approach, 40 participants who presented with an acute sprained ankle and their treating clinicians completed two questionnaires related to function at the start and end of a rehabilitation programme. Additionally, participants completed the questionnaires at 6 weeks following discharge at which time they also performed physical tasks that were still perceived as difficult. Ten participants also completed a semi-structured interview. RESULTS: There were no significant differences (p > 0.05) in the participant's and clinician's initial assessment of function. However, at discharge participants scored their function significantly (p < 0.05) lower than clinicians. This difference was not apparent 6 weeks later (p > 0.05). However, there was a significant difference (p < 0.05) following actual performance of tasks with an effect size of 1.58. Participant interviews confirmed that patients had a fear of re-injury until they actually performed tasks that were perceived as difficult. CONCLUSIONS: Clinicians and participants do not have a similar perception of the recovery of an ankle sprain at discharge. Performing tasks which were perceived as difficult were valuable in assisting participants gain an improved appreciation of their function.
