Modulating Locomotor-Respiratory Coupling Through Adaptive Exoskeleton Assistance in Patients With COPD
Sponsor: University of Nebraska
Summary
1\) Purpose: To improve pulmonary rehabilitation outcomes for individuals with COPD by evaluating the effectiveness of a hip-assisted exoskeleton during a single pulmonary rehabilitation session. 2) Eligibility criteria: Participants must be between 45-75 years old, any gender, but must have a BMI of less than 35 kg/m\^2, free from co-morbidities that may affect walking patterns, and must have moderate to severe COPD with no other pulmonary or cardiac issues. (Eligible participants will undergo a screening process which includes 6-minute walking test, medical history exam, and spirometry evaluation.) 3) Intervention and evaluation: The experimental collection will be conducted at the Biomechanics Research Building at the University of Nebraska at Omaha. Participants are required to participate in two sessions on two separate days, both including a 30-minute walking session with one session wearing the hip exoskeleton and the other session without the device.

Interventions
Hip Exoskeleton-Assisted Walking
The intervention is a wearable hip exoskeleton designed to provide assistive torque during treadmill walking. During the assisted walking condition, participants will wear the exoskeleton secured around the waist and thighs. The device will provide powered assistance to the hip joints during walking to reduce the physical demand of locomotion. Participants will complete a 30-minute treadmill walking session at an individualized workload determined during an initial exercise calibration visit. The effects of hip exoskeleton assistance will be evaluated by comparing physiological, respiratory, biomechanical, and exercise tolerance outcomes with a standard walking condition performed without exoskeleton assistance.
