Abstract: Objective: This study explores the effects of arm wing restraint on walking patterns so as to provide theoretical support for the design of no-arm human-simulation robots and prosthetic devices. Methods: Choosing ten young male students as subjects and asking them to walk at the speed of 1.5+-0.3m/s while swinging their arms naturally and walking with their arms restrained respectively. Using Kistler’s 3D force platform and the infrared high-speed motion capture system to collect subjects’ kinetic and kinematic data. Results: (1) Arms swing restraint will significantly reduce the walking frequency; (2) arm swing restraint will dramatically increase the vertical range of gravity movement and the rotary angle of pelvis; (3) under the two different motion conditions, biomechanic parameters present significant differentiation; (4) under the two walking patterns, lower limb parameters are highly correlated (r>0,90) . Conclusion: Arm swing during walking will reduce legs’ energy consumption. Therefore it is a kind of energy-saving walking pattern. The motion pattern of lower limbs under the two walking conditions is highly identical.
