This study is aimed to evaluate whether transcutaneous spinal cord stimulation (tSCS) can augment robotic gait training (RGT) to improve functional mobility in participants with chronic spinal cord injuries. It also evaluate the impact of the tSCS+RGT on health-related quality of life (HRQOL), compared to RGT alone.
This is a prospective single-arm crossover study in participants with incomplete chronic traumatic spinal cord injury. 6 subjects with paraplegia and 6 subjects with tetraplegia will be recruited. The intervention includes Phase 1 of training which consists of 16 sessions of robotic gait training (RGT) + conventional physiotherapy in 8-10 weeks, and Phase 2 of training which consists of 16 sessions of RGT training + tSCS + conventional physiotherapy in 8-10 weeks.
Outcome measures including mobility function assessment and neuromuscular assessment will be collected at Baseline, Post-Phase 1 and Post-Phase 2. A satisfaction survey on the intervention "RGT training + tSCS + conventional physiotherapy" will be performed at week-18 assessment.
Between 6 months to 5 years from the diagnosis of the traumatic SCI and who are not walking independently;
Age between 21 to 65 years old;
Incomplete spinal cord injury: ASIA Impairment Scale (AIS) Grade: B-D;
Spinal cord injury level: T1- L1, or C2-C8;
Participant has uncontrolled cardiopulmonary disease or cardiac symptoms as determined by the investigator;
Participant has any unstable or significant medical condition that is likely to interfere with study procedures or likely to confound performance and outcomes like uncontrolled neuropathic pain, depression, severe cognitive impairment;
Unstable or uncontrolled autonomic dysreflexia;
Requires ventilator support;
Crossover
RGT+ tSCS + conventional physiotherap
DeviceSubject will undergo 16 sessions of robotic gait training (RGT) + tSCS+ conventional physiotherapy in 8-10 weeks. Subject will walk with EksoGT for gait training during RGT training. Components of conventional physiotherapy will include upper/lower limb ergometry and strength training as prescribed by the attending physiotherapist based on their assessment. During tSCS, cathodes will be placed on the T11 and L1 spinous process. Reference/Ground electrodes placed over the ASIS It will be on biphasic mode with an overlap frequency of 10kHz, Burst Frequency of 30Hz, Pulse width of 1ms. Stimulation intensity ranges from 5-100 mA and will be adjusted according to the patient's response. The tSCS stimulation duration for each session will be 45 minutes in conjunction with the RGT training.

Spinal Cord Injury - Trunk Control Test (SCI-TCT)
It measures 4 simple aspect of trunk movement: 1) rolling to weak side; 2) rolling to strong side; 3) balance in sitting position; 4) sit up from lying down. The final score ranges from 0 (minimum) to 100 (maximum, indicating better performance)

Walking Index in Spinal Cord Injury-II (WISCI-II)
It is an ordinal scale of 20 items assessing the amount of physical assistance needed, as well as device required, for walking following paralysis that results from spinal cord injury. Final score ranges from 0 (minimum) to 20 (maximum, indicating better performance).
EQ5D
EQ5D is an instrument which evaluates the generic quality of life developed in Europe and widely used. It has one question for each of the five dimensions that include mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each dimension scored from 1 to 5, the higher score indicates worse performance.

Modified Tardieu Scale
Modified Tardieu Scale is to measure if there is spasticity present in a person's muscle and its response to movement. It will be measured for Quadriceps, Hamstrings, Gastrocnemius. A large difference between R1 and R2 suggests a large dynamic component with a greater capacity for change or improvement. A small difference between R1 and R2 suggests a predominantly fixed contracture in the muscle with a poorer capacity for change
