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 paraplegia. 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 paraplegia. 6 subjects 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.

This is a prospective single-arm crossover study in participants with incomplete chronic traumatic spinal cord paraplegia. 6 subjects will be recruited. Once subject is identified to be eligible for the study and is agreeable to participate into the study, he/she will undergo Phase 1 of training which consists of 16 sessions of robotic gait training (RGT) + conventional physiotherapy in 8-10 weeks. After a 1-week washout period, subject will undergo Phase 2 of training which consists of 16 sessions of RGT training + 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. Outcome measures including mobility function assessment and neuromuscular assessment will be collected at Baseline (within 1 week before the starting of Phase 1 of training), Post-Phase 1 (within 1 week after Phase 1 of training) and Post-Phase 2 (within 1 week after Phase 2 of training). A satisfaction survey on the intervention "RGT training + tSCS + conventional physiotherapy" will be performed at week-18 assessment.

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).

Central motor conduction time (CMCT)
Measured by transcranial magnetic stimulation (TMS). It is calculated by subtracting the peripheral conduction time (PMCT) from motor evoked potential (MEP) latency elicited by TMS to the motor cortex. Higher results indicates longer central motor conduction time and poor performance.

International standards for Neurological Classification of SCI (ISNCSCI)
The test is to define and describe the extent and severity of a patient's spinal cord injury. The patient's grade is based on how much sensation he or she can feel at multiple points on the body, as well as tests of motor function. The results ranged from A (worst- complete lack of motor and sensory function below the level of injury) to E (best, all neurologic function has returned)

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
