CONTEXT: Posterior calf stretching is believed to improve active ankle dorsiflexion range of motion (AADFROM) after acute ankle-inversion sprain. OBJECTIVE: To describe AADFROM at baseline (postinjury) and at 2-wk time periods for 6 wk after acute inversion sprain. DESIGN: Randomized trial. SETTING: Sports clinic. PARTICIPANTS: 11 men and 11 women (age range 11 to 54 y) with acute inversion sprain. INTERVENTION: Standardized home exercise program for acute inversion sprain. MAIN OUTCOME MEASURE: AADFROM with the knee extended. RESULTS: Time main effect on AADFROM was significant (F3,57 = 108, p < 0.001). At baseline, mean active sagittal-plane motion of the ankle was 6 degrees of plantar flexion, whereas at 2, 4, and 6 wk AADFROM was 7 degrees, 11 degrees, and 11 degrees, respectively. CONCLUSIONS: AADFROM increased significantly from baseline to week 2 and from week 2 to week 4. Normal AADFROM was restored within 4 wk after acute inversion sprain.
