Description

With the aim of designing a jacket that an elderly person can put on without difficulty, the motions of putting on jackets (Jacket A, basic ease; Jacket B, like Jacket A but with two pleats added to the back so that the back part can become wider) were recorded with eight digital video cameras followed by three-dimensional motion analysis in 46 healthy elderly women (mean age, 75.1 years). The active range of motion of the acromioclavicular joint and the angle of the upper limb were also measured. The maximal adduction angle of the shoulder joint was negatively correlated with the time it took to put the second wrist through the armhole of Jacket A (r=-0.48). By studying the position of the arm, the following was clarified: since the maximal horizontal adduction of the shoulder generally decreased in elderly women compared with younger women, the subjects adducted the upper limb to raise the wrist so that it could reach the armhole of Jacket A. When the maximal horizontal adduction of the shoulder decreased, it took the subjects longer to put on the jacket and they experience difficulty. It was easier for subjects to put on Jacket B because they could pull the armhole forward to the wrist.
