The patients often ask us to improve daily movements involving the upper limbs in shoulder rehabilitation. Daily movements using the upper limbs are done with many variations, even by healthy people, and we have to understand these variations. In the rehabilitation of daily movements, we need to set a goal about how the patient will perform. In addition, daily movements using the upper limbs constitute multiple joint movements, not only shoulder joint movement, so there are mutual relationships with multiple joint movements. Therefore, we have to make a hypothesis while thinking about the relationships among the multiple joint movements.
