Background: Patients with subacute unilateral lateral ankle sprain commonly experience pain and limited range of motion (ROM). Measurement reliability should be investigated before assessing treatment effectiveness. Objective: To determine both intra-rater and inter-rater reliability and minimal detectable change (MDC) of visual analog scale (VAS) and digital goniometer in patients with subacute unilateral lateral ankle sprain. Methods: Ten subjects (7 men, 3 women; aged 29.90 12.81 years) with subacute unilateral lateral ankle sprain were recruited. Two investigators measured pain intensity and ROM using VAS and a digital goniometer, respectively, with a 30-minute break between measurements. The same protocol was repeated …
