Exoskeleton Device

This study aims to evaluate the effects of powered lower-limb exoskeleton-assisted training on lower limb strength, respiratory parameters, 28-day ventilator-free days, and length of hospital stay in patients with prolonged mechanical ventilation admitted to a Respiratory Care Center. The goal is to provide clinical evidence for integrating rehabilitation and respiratory care in this patient population.

The goal of this interventional study is to evaluate the effect of three different designs of trunk assistance exoskeletons on cumulative lumbar load, trunk extensors' muscular fatigue and comfort in healthy volunteers. The main questions it aims to answer is: will exoskeletons reduce muscle fatigue and cumulative lumbar load. Participants will : * get each exoskeletons adjusted and then practice the lifting task and measurement sequence in a first session * perform a lifting task for 4 blocks of 20 minutes on different sessions for each exoskeleton, another session is performed without assistance.

Systematic and professional rehabilitation training is generally effective for patients with lower limb dyskinesia, but most of them lose the chance of recovery due to failure to receive systematic rehabilitation treatment. Our team has developed an intelligent power armor for patients with lower limb motor dysfunction, which can assist patients to complete high-quality rehabilitation training. In order to evaluate the safety and efficacy of the Smart Power Armor for post-surgical spine patients, and to provide data support for a confirmatory clinical study, we designed a single-center, prospective, randomized controlled study to compare the level of recovery of lower limb motor function in patients with different rehabilitation strategies.
