Efficacy of thrust and nonthrust manipulation and exercise with or without the addition of myofascial therapy for the management of acute inversion ankle sprain: a randomized clinical trial

Randomized clinical trial. To compare the effects of thrust and nonthrust manipulation and exercises with and without the addition of myofascial therapy for the treatment of acute inversion ankle sprain. Studies have reported that thrust and nonthrust manipulations of the ankle joint are effective for the management of patients post-ankle sprain. However, it is not known whether the inclusion of soft tissue myofascial therapy could further improve clinical and functional outcomes. Fifty patients (37 men and 13 women; mean ± SD age, 33 ± 10 years) post-acute inversion ankle sprain were randomly assigned to 2 groups: a comparison group that received a thrust and nonthrust manipulation and exercise intervention, and an experimental group that received the same protocol and myofascial therapy. The primary outcomes were ankle pain at rest and functional ability. Additionally, ankle mobility and pressure pain threshold over the ankle were assessed by a clinician who was blinded to the treatment allocation. Outcomes of interest were captured at baseline, immediately after the treatment period, and at a 1-month follow-up. The primary analysis was the group-by-time interaction. The 2-by-3 mixed-model analyses of variance revealed a significant group-by-time interaction for ankle pain (P
