  1. HF high flexion
  2. aData are given as number (percentage). HF activities were evaluated using a self-administered questionnaire [13]. Grade means degree of difficulty for a particular activity. Grade 0: no difficulty, grade 1: mild difficulty, grade 2: moderate difficulty, grade 3: severe difficulty and grade 4: extreme difficulty (unable to do)
  3. bGrade 0, 1, and 2 were considered positive responses
  4. cGrade 3 and 4 are considered negative responses
