Pain, functional disability, psychological status, and health-related quality of life in patients with subacromial impingement syndrome

Figures & data

Table 1. Summary of the FIT-HaNSA* testing protocol

Tasks	Lower shelf position	Higher shelf position	Action	Guide	Duration
Task1: Waist up	Waist level	25 cm above the lower shelf	Lifting 3 weights from lower to higher shelf and return	Metronome set at 60 beats/min—Coloured spots on shelves	5 min
Rest					30 sec
Task 2: Eye-down	25 cm below the higher shelf	Eye-level	Lifting 3 weights from lower to higher shelf and return	Metronome set at 60 beats/min—Coloured spots on shelves	5 min
Rest					30 sec
Task 3: Over-head	No	Eye-level with perpendicular plate	Moving two bolts between three holes in rotation	Holes in the perpendicular plate	5 min

Note: FIT-HaNSA* = The functional impairment test-head, and neck/shoulder/arm.
