Short-term whole-body vibration at different frequencies for people with COPD and healthy adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study compares the immediate (acute) effects of different whole-body vibration (WBV) frequencies applied to both clinically diagnosed COPD patients and healthy adults aged 18–65. Participants who meet inclusion criteria and have no contraindications will receive brief WBV sessions at varying frequencies while researchers measure respiratory function, symptom reports, and muscle performance. The protocol excludes people with implants, pacemakers, recent surgery or wounds, pregnancy, severe cardiovascular disease, uncontrolled comorbidities, or regular high-frequency exercise habits. Outcomes focus on short-term physiological and functional changes rather than long-term rehabilitation effects.
