Powered Assist Hip Exoskeleton to Improve Ambulation in Severe Lung Disease
A study testing exoskeleton assist in people with Lung Disease Chronic, run by West Park Healthcare Centre at 1 site in Canada.
Trial summary
Chronic respiratory disease (CRD) is among the most prevalent and growing diseases worldwide with disabling consequences. Many with a compromised respiratory system cannot support the metabolic energy demands of walking causing them to walk slowly and stop often. Read more about this study

About this study
Official title: Exoskeleton Assist to Improve Physical Performance in Patients With Very Severe Chronic Respiratory Disease
Chronic respiratory disease (CRD) is among the most prevalent and growing diseases worldwide with disabling consequences. Many with a compromised respiratory system cannot support the metabolic energy demands of walking causing them to walk slowly and stop often. Those with CRD could receive substantial benefit from a powered wearable exoskeleton device that assumes part of the energy of walking. Assisting the legs will lower the metabolic energy demands, and therefore the ventilation required for exercise, thereby allowing them to walk faster and further. Proposed is a series of single-case experiments comparing walking endurance with and without a powered hip exoskeleton assist. The aim of this study is to determine the efficacy of an exoskeleton on walking endurance in ventilatory limited patients with CRD. An exoskeleton could be a novel immediate and long term strategy to augment walking as part of the spectrum of pulmonary rehabilitation and community reintegration.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
exoskeleton assistDevice
A powered exoskeleton describes a wearable robot designed around the shape and function of the human body with segments and joints externally coupled to those of the user. The exoskeleton includes a rigid outer frame, sensors that detect a user's desired movements, a computerized controller, motors and actuators, and lightweight batteries.
The exoskeleton is designed to be worn in the community.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
walking endurance time (time frame: an average of 7 tests over 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05835271, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2026.
