NCT05352100

Brief Summary

Objective: Test the ability of vibration to produce physiologic, biochemical, and anatomic changes consistent with exercise that would help prevent the development of muscle weakness that occurs when patients are immobile for long periods of time.

Study Arms (1)

Hospitalized patients

EXPERIMENTAL

This phase will recruit hospitalized bedridden patients who will be vibrated with the prototype device using various vibration frequencies to determine which frequency produces the optimal physiologic response. Physiologic responses will be determined with a number of devices capable of measuring such things as tissue oxygenation, oxygen consumption, and muscle activity. Blood samples will also be taken to measure certain chemical markers associated with activity and increase blood flow. They may receive multiple 5 minute episodes of various vibration frequencies.

Diagnostic Test: Therapeutic Vibration Device

Interventions

The Therapeutic Vibration Device is capable of applying force through the axial skeletal spine, through bidirectional compression loading (or prestressing) between the shoulder and the plantar surfaces of the feet. It is placed around the body like a mobile frame so that the applied vibration can affect the whole body. The vibration actuators (drivers) are mobile and can vary in size, frequency response, and force. The design minimizes the possibility of mechanical interference for ventilated/intubated patients.
