Evaluation of Weight Shift and X-Factor During Golf Swing of Veterans With Lower Limb Loss.

Abstract

The purpose of this study was to assess the weight shift and X-Factor values of golfers with lower limb loss. Veterans with above or below knee limb loss participated in a 3-day adaptive golf event hosted by the Department of Veterans Affairs. Professional golf instructors educated participants on proper golf swing mechanics, after which kinematic analysis of trunk rotation and kinetic analysis of weight transfer between the legs during the golf swing were evaluated using three-dimensional motion capture and force platforms. Golfers with a trail leg amputation, regardless of level of limb loss, demonstrated superior weight shift, whereas golfers with lead limb amputation showed greater X-Factor values (all P < 0.05). Golfers with below knee limb loss demonstrated better weight shift strategies compared to those with above knee limb loss, regardless of which leg was amputated (i.e., lead or trail limb, all P < 0.05). Sports rehabilitation programs should focus on increased weight bearing on the prosthetic limb to achieve appropriate weight shift and increased flexibility to increase X-Factor values. Participation in such programs can offer both physical and psychosocial benefits and may be a valid tool to increase the overall quality of life of veterans with lower limb loss.
