简要总结

This study aims to evaluate the safety and usability of a motorized mobility assistance exoskeleton (MAK). The procedure explores the use of the MAK exoskeleton during the static and dynamic rehabilitation sessions with the intention to evaluate the safety and usability of the device in the studied population. The protocol has been focused on defining how the device can be used appropriately in this population in a safe manner by rehabilitation specialists.The study also aims to assess the safety of clinicians implementing the intervention, as well as possible benefits derived from the use of the device. As a secondary outcome, efficacy measurements will be collected.

排除标准

  • Spasticity > 3 in lower limbs according to the MAS scale
  • Skin alterations in the contact areas with the exoskeleton
  • Planned surgical intervention during the duration of the study
  • Two or more osteoporotic fractures in the lower limbs in the last 2 years
  • Presence of other pathologies that cause exercise intolerance (such as uncontrolled hypertension, coronary artery disease, arrhythmia, congestive heart failure, Parkinson's, severe lung disease)
  • Surgical operation in the 3 months prior to the start of the study on the lower limbs
