The influence of the arm swing on the gait has been investigated by using the simple model. The model consists mainly of the shoulder, the waist, and the torsional spring as the backbone w hich connects the shoulder and the waist. Two arms and two legs are also pinned to appropriate positions. Variations of the swing angle of the leg and the twist angle of the waist associated with the sinusoidal swing of arms were numercally calculated for following three cases: Ⅰ alternation of the periods during which each foot is fixed, Ⅱ alternation of the period during which one foot is fixed and the period during which both feet are fixed, Ⅲ adding to the pattern, case Ⅱ, one foot can be swinged when the other foot is fixed. Obtained variations are consistent with the actual. The model used in this in vestigation aids us to understand how the swing of arms assists the leg to swing forward.
