To help walking, using assistive devices can be considered to reduce the loads caused by weight and to effectively decrease the propulsive forces. In this study, a mobility Saddle-Assistive Device (S-AD) supporting body weight while walking was evaluated on two healthy volunteers. This device is based on the support of body weight against gravity with the help of a saddle, which is not used in other passive mobility assistive devices. To prove the efficiency of this device, the experimental results obtained while walking with this device were compared with those related to walking without the assistive device. The results showed that this device could significantly reduce the forces and torque of the lower and upper limbs when walking. By distributing the load on the saddle, the vertical force and the propulsive force in the best conditions were decreased to 46.7% and were increased to 13.7% in body weight, respectively. Using a S-AD can help patients with lower limbs weakness and elderly people to walk.

为了帮助行走，可以考虑使用辅助装置来减轻由重量引起的负荷并有效地减小推进力。在这项研究中，对两名健康志愿者评估了支持步行时体重的移动式鞍辅助装置（S-AD）。该设备基于在鞍座的帮助下对体重的支撑，该鞍座未在其他被动移动辅助设备中使用。为了证明该装置的效率，将使用该装置行走时获得的实验结果与不使用辅助装置行走时获得的实验结果进行了比较。结果表明，该装置可以显着减小步行时上下肢的力量和扭矩。通过分配鞍座上的负载，最佳状态下的垂直力和推进力分别降低到46.7％和增加到13.7％。使用S-AD可以帮助下肢无力和老年人走路。
