The device utilized EMG sensors to collect signals from the leg muscles, which then controlled the cycling motion. This group underwent specific training sessions designed to enhance muscle activation on the affected side by inducing voluntary contractions through cycling, with the aim of improving muscle strength, balance, and activities of daily living. The sessions included a structured regimen of warm-up, active cycling with therapist-guided acceleration based on muscle activation, and cool-down periods, conducted under supervision for safety and effectiveness.

This group followed a similar session structure to the CIMCT group, including warm-up, cycling at a comfortable pace, and cool-down phases, but without the targeted muscle activation component.

The study tested an EMG-triggered CIMCT device for stroke rehab, involving EMG sensors, a stationary bike, and a control unit displaying muscle activity. The protocol included warm-up, therapist-guided exercises, and cool-down, performed under supervision.

A manual muscle tester (Model 01163, Lafayette, USA, 2003) was used to evaluate lower extremity muscle strength in this study. The knee extensors, knee flexors, dorsiflexors, and plantar flexors, which are primarily responsible for the pedaling motion, were assessed. Moreover, both sides were evaluated.

This study utilized a commercially available GB300 (Metitur Ltd., Jyvaskyla, Finland) posture measurement system for posture measurement, which included a movable triangular-shaped platform and a ruler that displayed the position of the feet. The aforementioned system was useful for analyzing balance problems and the effectiveness of rehabilitation. The posture management system is also commonly used to assess balance ability in athletes, older individuals, patients with stroke, and patients with hemiplegia. The sampling frequency was set at 50 Hz. The participants stood with their eyes open and facing forward for 30 s while fixed to the equipment; this was repeated three times. Subsequently, they stood in the same position with their eyes closed and facing forward for 30 s for three additional measurements.

The Timed up-and-go (TUG) test was used to assess the balance ability in this study. In the test, the participant sits in a chair with armrests, rises from the chair at the same time as the word "start" is spoken, walks at the most stable and comfortable speed to a point 3 m in front of them, and then returns and measures the time to sit down in the chair. It has a high intra-rater reliability (r=.99) and inter-rater reliability (r=.98). The raters performed three measurements using a stopwatch and recorded the average value.

The Berg Balance Scale is used to assess functional balance in a wide range of participants, including older individuals at a high risk of falling and patients with acute and chronic diseases. Moreover, Berg Balance Scale is a functional balance test method that considers three aspects of functional balance: postural maintenance, postural control by manual exercise, and response to external perturbations. these activities are scored from 0 to 4, with 0 being the worst and 4 being the best performance of independent tasks. The maximum total score is 56 points. A lower score suggests impaired stability.
