1. Lifting an object to a shelf	From a standing or sitting position, the subject lifts a 1-kg object from a table to a high shelf. The task is repeated three times without a break. The height of the shelf should be slightly above the subject's head, and the difference in height between the table and the shelf is at least 0.7 m.	Lift the object up on the shelf and back on the table three times.	1	2	3	4	5
2. Putting on a jacket	From a standing or sitting position, the subject puts on a jacket with the healthy arm in the first sleeve and then off beginning with the painful arm. The jacket should be medium tight and made of non-stretchy material.	Put on the jacket with the healthy arm in the first sleeve and take it off with the painful arm first.	1	2	3	4	5
3. Moving an arm sideways	From a sitting position, with approximately 90° angle in the hip and knee, the subject lifts a 2-kg object with a straight and approximately 90° internal rotated arm, from a table in front and to the height of the shoulder. The arm is now at 90° flexion, internal rotated in a sagittal plane. The straight arm is abducted to the frontal plane, and adducted to the sagittal plane without allowing any variation in the height or the rotation of the arm. The task is repeated once without a break.	Lift the object up from the desk to shoulder height with a straight arm. Keep the upper body stable. Move the object sideways until the arm is outside the shoulder, and then back to forward position. Keep the arm at shoulder level and straight through the movement. The task is repeated once without a break.	1	2	3	4	5
