Motor-assisted Cycling and FES Cycling for Postprandial Glucose in Diabetic Patients With ADL Disability

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03994289

Brief Summary:
Exercise has been the cornerstone of diabetes management. However, many diabetic patients have ADL disabilities and experience substantial difficulty in performing usual exercises, such as brisk walking and upright cycling. There is an urgent need to provide alternative exercise modalities for diabetic patients with ADL disabilities. In this study, investigators will investigate the effects on the glucose of three exercise modalities, including motor-assisted cycling (i.e., cycling on a motor-driven bike) and functional electrical stimulation (FES) cycling, during which the investigators will use electrical current to facilitate cycling movements.

Arm Intervention/treatment
No Intervention: Control
Participants remain seated for 2 hours after the intake of a standardized breakfast.
Experimental: Motor-assisted cycling
Participants will perform 3 bouts of motor-assisted cycling, each bout lasting 10 minutes, after the intake of a standardized breakfast.
Behavioral: Motor-assisted cycling
Participants will perform the motor-assisted cycling exercise using a physical therapy bike (RECK; Betzenweiler, Germany). Participants will perform 3×10-min bouts of motor-assisted cycling at the highest tolerable cadence. Before each bout, participants will perform 1-2 minutes of motor-assisted cycling at 5-10 rpm as a warm-up.

Experimental: FES cycling
Participants will perform 3 bouts of FES cycling, each bout lasting 10 minutes, after the intake of a standardized breakfast.
Behavioral: FES cycling

The testing procedures will be identical to that in the motor-assisted cycling visit except for the exercise type. Participants will wear FES cuffs on the upper and lower legs, bilaterally.

. The FES cycling will be performed on the motor-assisted bike using the wearable FES equipment. The purpose of motor-assisted cycling is to provide constant cadence. The Bioness L300 Plus system (Bioness, Valencia, CA) will be worn on the upper and lower legs to stimulates the quadriceps and dorsiflexors muscles during the motor-driven cycling exercise. An embedded gyroscope of the cuff can detect the motion of the lower leg so that the electrical stimulations will be generated at appropriate timing to activate leg muscles during the cycling exercise.

Primary Outcome Measures :
  1. Postprandial glucose AUC [ Time Frame: The glucose will be measured using CGM during the 2-hour postprandial period. ]
