Pilot Study for Peripheral Neuromuscular Electrical Stimulation of the Quadriceps Muscle

May 24, 2023 updated by: University of Sao Paulo General Hospital

Pilot Study for Peripheral Neuromuscular Electrical Stimulation of the Quadriceps Muscle: Healthy or Deprived of Central Nervous System Control

Feasibility study of a new medical device that will evaluate the usability and effectiveness of a cycle ergometer device associated with neuromuscular electrical stimulation (FES cycling). The study's objective is to evaluate the effect of the application of functional electrical stimulation of the new device on participants' quadriceps muscle strength in comparison to a medical device with similar characteristics and to a control group. Secondarily, the study will compare the usability of the two medical devices as evaluated by the participants and the therapists who apply the treatment, as well as the participants' satisfaction with the treatment, identifying possible adverse effects.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Experimental: Experimental FES cycling
New medical device combining cycle ergometer use and neuromuscular electrical stimulation (FES cycling)
Device: Experimental FES cycling
Using the experimental, new FES cycling device, provide neuromuscular electrical stimulation of the gluteal, quadriceps and hamstring muscles at sufficient intensity to cause muscle contraction and push the cycle ergometer pedals for 30 minutes, for 16 treatment sessions (twice a week, for 8 weeks), in addition to conventional physical therapy for muscle strengthening.
Active Comparator: Comparator FES cycling
Existing medical device combining cycle ergometer use and neuromuscular electrical stimulation (FES cycling)
Device: Comparator FES cycling
Using the comparator, marketed FES cycling device, provide neuromuscular electrical stimulation of the gluteal, quadriceps and hamstring muscles at sufficient intensity to cause muscle contraction and push the cycle ergometer pedals for 30 minutes, for 16 treatment sessions (twice a week, for 8 weeks), in addition to conventional physical therapy for muscle strengthening.
Active Comparator: Conventional physical therapy
Conventional physical therapy.
Other: Conventional physical therapy
Conventional physical therapy for muscle strengthening, for 16 treatment sessions (twice a week, for 8 weeks).
No Intervention: Operators
Operators will evaluate systems usability during interventions.
