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.
本研究旨在评估下肢截肢者的重心转移和 X 因子值。
参加由美国退伍军人事务部主办的为期 3 天适应性高尔夫活动的下肢截肢退伍军人。专业的高尔夫教练向参与者传授正确的高尔夫挥杆力学，之后使用三维运动捕捉和力台评估在高尔夫挥杆过程中躯干旋转的运动学分析和腿部之间的重量转移的动力学分析。
无论截肢水平如何， trailed 腿截肢的高尔夫球手表现出更好的重心转移，而 lead 腿截肢的高尔夫球手表现出更大的 X 因子值（均 P < 0.05）。与 above knee 肢体缺失的高尔夫球手相比，below knee 肢体缺失的高尔夫球手无论截肢的是哪条腿（即 lead 或 trailed 肢体），都表现出更好的重心转移策略（均 P < 0.05）。
运动康复计划应侧重于增加假肢上的负重以实现适当的重心转移，并增加灵活性以增加 X 因子值。参加此类计划可以带来身体和心理社会方面的益处，并且可能是提高下肢截肢退伍军人整体生活质量的有效工具。
