Heart Failure Clinical Trial

Official title: Isolated Resistance Training Program Versus Combined With Neuromuscular Electrical Stimulation for Femoral Quadriceps in Patients With Femoral Intra Aortic Balloon Pump: Randomized Controlled Trial

Status Not yet recruiting

Clinical Trial Summary

The objective of this randomized clinical trial is to compare the effects of a standardized exercise program alone versus the same program combined with neuromuscular electrical stimulation in patients undergoing heart failure . The main questions it aims to answer are: - Assessing the ultrasonographic parameters: echo intensity (echogenicity), cross-sectional area, thickness, and pennation angle of the rectus femoris muscle in both lower limbs. - Evaluating the strength of the femoral quadriceps muscle - Evaluating the changes in the chronaxie of the rectus femoris muscle in both lower limbs The protocol will have a total duration of 35 days, with an initial intervention period of 21 days (5 days per week), followed by a 14-day follow-up period.

Clinical Trial Description

- Introduction: Patients with refractory heart failure who develop cardiogenic shock may require the use of an intra aortic balloon pump. This device, when inserted through the femoral artery, necessitates bed rest and increases the incidence of muscle mass loss. Rehabilitation programs in the intensive care unit that include resistive training bring benefits such as improving muscle architecture, strength, and function. Neuromuscular electrical stimulation (NMES) can be an important tool to assess excitability and improve muscle strength through muscle contractions generated by motor axon depolarization. Muscle ultrasonography is currently used as a tool for evaluating and monitoring muscle architecture (echointensity) and mass. - Objectives: To evaluate the effect of combining NMES with a standardized exercise program on the echointensity (echogenicity) of the rectus femoris muscle in hemodynamically stable patients using an intra aortic balloon pump. - Method: This is a randomized controlled clinical trial comparing two groups: one group will perform resisted knee extension exercises in both lower limbs, while the other group will perform the same exercises synchronously with NMES of the femoral quadriceps muscle. The resistance load will be determined by the one-repetition maximum test and adjusted if necessary. The intervention period will be 21 days (5 days/week) with a follow-up of 14 days. Muscle architecture and mass (ultrasonography), neuromuscular excitability (using the same NMES device), and knee extension strength (dynamometry) will be assessed at baseline, on the 14th, 21st, and 35th days. ;
