Trial Outcomes & Findings for Building Strength Through Rehabilitation for Heart Failure Patients (BISTRO-STUDY) (NCT NCT03615469)
NCT ID: NCT03615469
Last Updated: 2023-05-31
Results Overview
The 6-min walk test (6MWT) estimates the person's ability to perform everyday activities by measuring the distance walked in a set time period. It will be used to measure exercise capacity, specific aim 2. Participants will be allowed use of an assistive device and will be instructed to move as quickly as they feel safe and comfortable over the 100-meter course for 6 minutes. As per the protocol, participants will be allowed to stop and rest if necessary. This test is recommended by the American Thoracic Society for patients with moderate to severe heart or lung disease.

Neuromusclar Electrical Stimulation
NMES will be set up with the machine on simultaneous large muscle atrophy setting with 500 ohm with peak of 50 volts, the "self-adhesive electrodes positioned on the thighs approximately 5 cm below the inguinal fold and 3 cm above the upper patella border" as described by Gobbo. When applying the stimulation, the intensity will be gradually increased from an intermittent tingling until a gentle pumping sensation is felt. Participants will direct the amount of stimulation acceptable on both thighs to improve acceptance of the modality. It is expected that tolerance will develop and intensity will increase over time.
|
Transcutaneous Electrical Stimulation
For the Sham group, electrodes will follow the same landmarks, but the stimulation will only increase to an intermittent tingling sensation with the machine setting on TENS instead of NMES which is not enough to make noticeable changes in muscle mass or circulation
Transcutaneous electrical stimulation: For the Sham group, electrodes will follow the same landmarks, but the stimulation will only increase to an intermittent tingling sensation with the machine setting on TENS instead of NMES which is not enough to make noticeable changes in muscle mass or circulation. Intensity settings will not change over time.
