  1. For illustrations of the handle types, see Fig. 3. Assessment was based on a 7-point Likert scale where 1 means “the worst” and 7 means “the best” for the constructs’ functionality and freedom of movement. Comfort was assessed on a 7-point Likert scale where 1 means “very uncomfortable” and 7 means “very comfortable”
