This project is randomized controlled trial which will explore the effect of pairing repetitive Transcranial Magnetic Stimulation (rTMS) with Functional Electrical Stimulation (FES) Cycling on lower extremity function in people with incomplete spinal cord injury and compare the effects to each one of these interventions alone.
Following a spinal cord injury, people often have decreased strength and balance in their legs, making it difficult to walk. To improve leg function in people with spinal cold injuries, the investigators can use electrical stimulation on muscles while participants are cycling to increase the muscle activation and nerve connections. Another way to improve the nerve connections to the muscles is by stimulating the brain directly. Previous research has looked at the effects of each of these treatments, but they have not been used together. In this study, the investigators will pair both electrical stimulation on the legs during cycling with brain stimulation or a sham brain stimulation to improve recovery and determine if using these methods together results in better outcomes, such as increased walking speed. Participants will attend training sessions for six weeks, twice per week. Each person will first receive the active or sham brain stimulation at the beginning of the session for 30 minutes and then they will receive the electrical stimulation on their legs while cycling for 60 minutes. Participants will be evaluated before the start of the treatment, in the middle of the study, at the final session, and again two weeks after the last session of the treatment. Assessments will include clinical tests of gait, balance, and strength. Inertial Measurement Units (IMU) and a pressure sensor gait mat will be used to evaluate the gait and balance parameters.

Willingness of participants to undergo therapy
This outcome will be evaluated through descriptive data. This outcome will be analyzed to evaluate the tolerability of the protocol. The willingness of participation will be collected on an 11-point numerical rating scale with 'not at all willing' at 0, and 'very willing' at 10 (measured at baseline).
Time frame: 8 weeks
Incidence of treatment-emergent adverse events
This outcome will be evaluated through descriptive data. Safety will be presented as any adverse reaction reported on verbal questioning at each session. The number of participants reporting adverse reactions, and the duration and severity of the adverse reactions will be reported.

Lower Extremity Motor Score (LEMS)
A blinded physiotherapist will be hired to collect this clinical outcome. Lower Extremity Motor Score is rated from 0 to 5\* as follows: 0= Total paralysis 1. Palpable or visible contraction 2. Active movement, full range of motion (ROM) when gravity is eliminated 3. Active movement, full ROM against gravity 4. Active movement, full ROM against gravity, and moderate resistance in muscle-specific position 5. (Normal) Active movement, full ROM against gravity, and full resistance in a muscle-specific position expected from a healthy person 5\*= (Normal) Active movement, full ROM against gravity, and sufficient resistance to be considered normal if identified inhibiting factors (i.e., pain, disuse) were not present NT = Not testable (i.e., due to immobilization, sever pain that can prevent the grading of the patient, amputation of the limb, or contracture of \>50% of the range of motion) Higher scores in this outcome mean better result.
Time frame: 8 weeks
Walking Index for Spinal Cord Injury (WISCI) II scale
A blinded physiotherapist will be hired to collect this clinical outcome. Walking Index for Spinal Cord Injury version II scale is rated from 0 to 20 with the higher scores showing better results.
