tSCS + EksoGT in SCI Patients
A Pilot Study on the Cumulative Effects of Transcutaneous Spinal Cord Stimulation (tSCS) With Robotic Gait Training in Trunk Muscle Activity and Walking Index in Chronic Spinal Cord Injury
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.

Detailed Description
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. 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.

Modified Tardieu Scale
Time Frame: Week 0
|
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
