About this study
Official title: Postprandial Glycemic and Physiological Responses to Walking With a Wearable Hip Exoskeleton in Healthy Adults: A Randomized Crossover Proof-of-Concept Study
This randomized crossover proof-of-concept study evaluated the effects of walking with a wearable hip exoskeleton on postprandial glycemic and physiological responses in healthy adults. Participants completed four experimental conditions: seated control, walking without the wearable hip exoskeleton, walking with the Bot-Fit device in Aqua mode, and walking with the Bot-Fit device in Boost mode. The primary aim was to determine whether walking with the wearable hip exoskeleton alters postprandial glucose responses compared with seated control and conventional walking conditions.
Read the detailed description
This study investigated whether walking with a wearable hip exoskeleton could modulate postprandial glycemic and physiological responses in healthy adults. Using a randomized crossover design, each participant completed four experimental conditions in a controlled laboratory setting: seated control, walking without the wearable hip exoskeleton, walking with the Bot-Fit device in Aqua mode, and walking with the Bot-Fit device in Boost mode.
Postprandial glucose responses were assessed after meal ingestion during each experimental trial. Physiological responses, including heart rate, perceived exertion, and energy expenditure, were also evaluated to compare the metabolic and perceptual demands of walking with and without the wearable hip exoskeleton. The study was designed as a proof-of-concept trial to examine whether wearable hip exoskeleton-assisted walking may influence postprandial glucose regulation in healthy adults.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Incremental Area Under the Curve for Postprandial Glucose (time frame: Up to 120 minutes after meal ingestion during each experimental trial). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 10 Jul 2026.
