護腕為滑板、滑雪等運動常見的防護設備,但是由於護腕的結構因素,仍有穿戴護腕者,超過一半以上因跌倒而仍然使手腕關節受傷害。因此本研究的目的在於以實際的人體向前跌倒方式,求得生物力學參數,進行評估不同護腕支撐材質的設計、不同的手肘策略與不同的跌落高度,對於地面衝擊力的吸收與上肢關節力的影響,以提供最佳之護腕設計。
本研究受測者為10位無肌肉骨骼方面疾病之年輕健康男性,以自製的懸吊系統模擬向前跌倒,使用動作分析系統(VICON460)包括六架CCD攝影機與一塊測力板(AMTI)以及加速規,用以同步擷取人體動作軌跡、地面反作用力與手掌背面加速規資料,分析比較1.不同護腕支撐材質包括赤手(Bare)、護腕夾板(Guard)、護墊置入護腕夾板內(In)與護腕移除手掌夾板,並將護墊附著於護腕外側(Out);2.不同策略包括手臂伸直與手臂彎曲;3.不同跌落高度包括4公分與8公分跌落高度等三個參數,對向前跌倒時人體運動、地面衝擊力、關節受力與振動頻域資料之影響。
實驗結果發現跌落高度增加,各狀態之地面反作用之峰值與負荷率、加速度峰值、地面反作用力頻域資料、肘關節之三軸力量與肘關節內外展力矩皆明顯增加。跌落時手臂自然彎曲能減少第一峰值,並且能延遲第一峰值發生時間,並且手臂彎曲時屈曲伸展力矩與內外轉力矩明顯大於手臂伸直之值。所有狀態下,In與Out狀態具有較佳吸收衝擊力效果。所以本研究之結論為降低跌落高度、使用In或Out之護腕形式,並幫助手臂彎曲策略運用,可以降低地面衝擊力,達到減少上肢傷害。
Wrist guards are one of the protective devices widely used for preventing from a distal radius fracture during in-line skating and snowboard-related activities. However, more than half of the people wearing wrist guards sustained a fracture of the wrist on forward falls. The purpose of this study is to evaluate the three factors, materials of wrist guard, fall heights and arrest strategies on impact force during forward fall by the biomechanical experiments.
Ten physically healthy male subjects volunteered for this investigation. None had ever suffered from upper extremity injuries or disorders. Trajection of human motion, ground reaction force (GRF) and acceleration (ACC) on the palm were collected using Motion Analysis System (VICON 460 and ATMI) from a self-established releasing system. Joint motion and force, GRF and ACC with respect to time and frequency domains were then analyzed for effects of three independent parameters on impact force during forward falls. The first parameter is the material of wrist guard including bare hand (Bare), common wrist guard (Guard), wrist guard with insole outside (Out) and wrist guard removing splint below with insole (In). The second parameter is the arrest strategy including elbow extended and flexed. The third parameter is fall height including 4cm and 8 cm above force plate.
The results of this study were as follows. The impact force, loading rate, peak value of ACC, and peak joint forces of elbow and abduction moment significantly increased as the increase of fall height. The strategy of elbow flexed could attenuate the peak GRF and delay the time of peak impact force. The extension moment of elbow in elbow flexied significantly increased than that in elbow extended. In the effect of materials, the GRF, loading rate and peak value of ACC with Out and In decreased significantly than those with Bare and Guard. The conclusion is that lower falling height, using wrist guard with a compliant pad (In or Out) and using the strategy of elbow flexed will decrease the impact force and the risk of injury of upper extremity.
