Critically-ill
Conditions
Brief summary
Critically-ill patients who have long stays in the hospital often face prolonged periods of bed rest. It is known that these patient develop profound weakness and debilitation. The effectiveness of existing muscle activation devices that could otherwise prevent the onset of debilitation in an immobilized patient has not been demonstrated widely in this cohort. It is hypothesized that using thermal methods to augment existing muscle activation techniques may demonstrate improved performance with no corresponding change in the safety profile.
Interventions
Thermal-aided muscle activation therapy will be provided to patients twice daily. Treatment will begin within 24 hours of admission and continue until patients are significantly ambulatory.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Muscle Activation Effectiveness | Day of ICU Discharge, expected on average 5 days | Research team will assess whether or not visible or palpable muscle contractions can be activated in the target patient population. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Muscle Strength | At enrollment, at ICU discharge (expected average days), at hospital discharge (expected average 10 days) | Muscle strength will be assessed using MRC scales at various time points throughout the study |
| Activities of Daily Living | At hospital discharge (expected average 10 days) | The subject's proficiencies and independence in Activities of Daily Living will be assessed prior to hospital discharge. |
| Six Minute Walk | At time of first ambulation (expected average 7 days), at hospital discharge (expected average 10 days) | A 6 minute walk test administered per ATS guidelines will be undertaken by all patients prior to discharge. When possible at least 2 six minute walk tests will be administered. |
| Muscle Mass | At enrollment, at ICU discharge (expected average days), at hospital discharge (expected average 10 days) | Muscle mass will be measured at several time points during the patient stay. |
| Length of stay | At end of study, expected on average after 10 days | The subject's length of stay will be recorded from chart review. |
| Ventilator Dependency | During active ventilation and weaning period, expected to last on average 4 - 7 days per patient | Chart review will be used to determine the number of ventilator days and the ventilator weaning time for each subject |
| Time to ambulation | During timeframe when patient moves out of bed, expected on average 5 - 8 days into study | The time needed for a patient who had previously been subjected to bed rest to ambulate will be noted through chart review and nursing interviews. |
