Task Practice and Spinal Cord Stimulation

Not Applicable

Not yet recruiting

• Conditions: Spinal Cord Injury Cervical; Spastic
• Interventions: Other: Task Practice combined with Transcutaneous Spinal Cord Stimulation( TcSCS)

• Registration Number: NCT06494020
• Lead Sponsor: University of Miami

Brief Summary

The goal of this study is to understand the effects of combined task practice with transcutaneous cervical spinal cord stimulation. The study will explore the effect of higher stimulation frequencies on spasticity. Transcutaneous stimulation has been shown to improve motor function in some individuals with chronic spinal cord injury. The study intends to explore scientifically the association between higher stimulation frequencies and spasticity/hypertonicity.

Arm && Interventions

Group	Intervention	Description
Task Practice with stimulation	Task Practice combined with Transcutaneous Spinal Cord Stimulation( TcSCS)	Participants in this group will receive combined Transcutaneous cervical spinal cord stimulation with task practice for up to 4 months.

Primary Outcome Measures

Name	Time	Method
Change in motor performance as measured by The Graded Refined Assessment of Strength, Sensibility, and Prehension (GRASSP) test	baseline, up to 6 months	GRASSP is a multimodal test that measures sensorimotor and prehension function in three domains that are important for the description of arm and hand functions, namely strength, sensation and prehension strength. It is an ordinal scale (minimum value = 0, maximum value = 100) with higher scores indicating better performance.; There is a sensation category ordinal scale (minimum value = 0 maximum value = 24) that measures sensation where higher scores indicate greater sensation.; The Prehension performance category has an ordinal scale (minimum value = 0 maximum value = 40) that measures prehension where higher scores indicate greater ability.

Secondary Outcome Measures

Name	Time	Method
Change in Spasticity as measured by Modified Ashworth Scale (MAS)	baseline, up to 6 months	6 category ordinal scale (minimum value = 0 maximum value = 4) that measures spasticity where higher scores indicate greater spasticity.
