Descriptive Information
Brief Title  ICMJE Exoskeleton Treatment of Deconditioning Due to Limited Ambulation Caused by Illness or Injury
Official Title  ICMJE Exoskeleton Treatment of Deconditioning Due to Limited Ambulation Caused by Illness or Injury
Brief Summary A safety and feasibility study of robotic exoskeleton training in deconditioned patients residing in a healthcare facility.
Detailed Description Patients who are hospitalized for several weeks or months are at a higher risk of decline in physical condition and are also at a higher risk of rehospitalization within 30 days of discharge. A program incorporating robotic exoskeleton training may provide sufficient physical support and challenge for patients to maintain a higher level of physical condition than if they did not undergo exoskeleton training. The investigators aim to demonstrate that EksoGT robotic exoskeleton training can be performed safely with patients who have been hospitalized and are at risk of experiencing a further decline in their physical condition.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description:
Single-arm safety and feasibility study.
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Debility Due to Disease
Intervention  ICMJE Device: EksoGT with SmartAssist software
Intervention will consist of exercise using the EksoGT exoskeleton for supported walking. The EksoGT is a powered motorized orthosis intended to enable individuals who are experiencing muscular or neurological conditions affecting their lower extremities to perform ambulatory functions such as gait training.
Study Arms  ICMJE Experimental: Interventional Group
All participants will be included in the interventional group. Intervention will consist of walking exercise using the EksoGT exoskeleton for supported walking, running SmartAssist software.
Intervention: Device: EksoGT with SmartAssist software
