About this trial
The ABT-TCSCS study investigates how feasible and beneficial are activity-based therapy and transcutaneous spinal cord stimulation on improving of arm and hand recovery after cervical spinal cord injury.

Trial design
Single group
Treatments tested in this trial
Activity-based therapy and transcutaneous spinal cord stimulation
Other interventionActivity Based Therapy (ABT) is a method of neuro-rehabilitation that incorporates a high intensity, long duration and effortful engagement from the individual receiving therapy, to garner improvements in sensory and motor function. The ABT constitutes 4 types of exercises including: cardio-fitness, resistance, postural/weightbearing and functional exercises. TransCutaneous Spinal Cord Stimulation (TCSCS) stimulates spinal networks in the cervical region to neuro-modulate the descending motor commands/motor intentions from the brain, which control the muscles. In tCSCS, electrical stimulation is delivered at a frequency of 30-50Hz at 500-1000µs between C3-C7. 12 sessions of ABT (4 weeks), followed by 28 sessions of ABT-TCSCS (7 weeks). Each session will last 1 hour and delivered 3 times per week.
Treatment groups
Trial outcomes
Primary outcomes
International Standards of Neurological Classification of SCI (ISNCSCI)
The ISNCSCI will be used to establish severity of injury, classify the sample and establish inclusion for study to be administered by clinicians. The ISNCSCI evaluates both motor and sensory impairment to determine the sensory and motor levels for the right and left side, the overall neurological level of the injury and completeness of the injury i.e. whether the injury is complete or incomplete. The severity of injury is graded as ASIA A = Complete, B (Sensory Incomplete), C (Motor Incomplete), D (Motor Incomplete), E (Normal).
Graded Redefined Assessment of Strength, Sensation and Prehension (GRASSP) Version 1
The GRASSP Version 1 evaluates sensorimotor and prehension function of upper extremity impairment and hand function through three domains: Strength, Sensation and Prehension. It will be administered by clinicians and takes about 30-45 minutes to complete.
Spinal Cord Independence Measure (SCIM)
The SCIM is a measure of independence and defines how much gain in global function one makes.
TRI hand function test (TRI-HFT)
TRI-HFT will be used as a measure of functional and performance change before and after intervention.
Secondary outcomes
Neurophysiological Assessment using surface electromyography (EMG)
Neurophysiological Assessment using surface EMG will be used to determine the responses to ABT and TCSCS in multiple upper limb muscles. sEMG responses to cervical spinal stimulation will be recorded simultaneously in multiple upper limb muscles unilaterally on the 1) deltoid anterior, 2) deltoid posterior, 3) biceps brachii, 4) triceps brachii, 5) flexor carpi radialis, 6) extensor carpi radialis, 7) abductor pollicis brevis, and 8) first dorsal interosseous muscles.
