根据人体生物力学，建立人体弯腰时的静力平衡模型，并在此基础上开发一种用于减轻背部竖脊肌负担的可穿戴弯腰助力装置(WSAD)，通过肌电(EMG)实验验证装置的有效性。实验结果表明，当人穿上助力装置向前弯腰到90o时，胸竖脊肌、腰竖脊肌、背阔肌、腹直肌的助力比为43%、48%、32%、14%。助力装置能减轻人体弯腰时背部竖脊肌的负担，从而减少腰背痛发病率，有利于长时间弯腰工作的劳动者。
根據人體生物力學，建立人體彎腰時的靜力平衡模型，併在此基礎上開髮一種用于減輕揹部豎脊肌負擔的可穿戴彎腰助力裝置(WSAD)，通過肌電(EMG)實驗驗證裝置的有效性。實驗結果錶明，噹人穿上助力裝置嚮前彎腰到90o時，胸豎脊肌、腰豎脊肌、揹闊肌、腹直肌的助力比為43%、48%、32%、14%。助力裝置能減輕人體彎腰時揹部豎脊肌的負擔，從而減少腰揹痛髮病率，有利于長時間彎腰工作的勞動者。

According to human biomechanics the ideal static equilibrium model of stooped human body was built, based on which a wearable stoop-assist device(WSAD) as an intervention to reduce the load on the erector spinae was developed. Electromyography(EMG) experiments were conducted to evaluate the effectiveness of the WSAD. Results showed that the integrated EMG of the thoracic erector spinae(TES), the lumbar erector spinae(LES), the latissimus dorsi(LD) and the rectus abdominis(RA) were reduced by 43%, 48%, 32% and 14% respectively, when Sagittal trunk bent forward to 90o from the vertical. Therefore, by reducing back erector spinae activity, the WSAD could reduce the incidence of developing LBP for those who adopt the prolonged stooped posture in work.
