Vibration therapy is a possible alternative to drug-based treatments for spasticity following SCI. Research indicates that it may provide temporary relief from spasticity, but many interventions under investigation are not portable and therefore access is limited. The aim of this study is to investigate the feasibility of using a portable vibrating device to decrease UE spasticity.

Inclusion Criteria:

• Any ISNCSCI severity classification (A, B, C or D)
• Have therapist-reported and self-reported spasticity in the arm or hand
• Ability to pick up, move, and release at least one block (on the Box & Blocks Test)
• May participate if utilizing prescription medications, including baclofen pump for control of spasticity

Exclusion Criteria:

• Severe contractures of the arm/hand that limit passive movement of the elbow, wrist or fingers more than 50% of normal range of motion or presence of other orthopedic pathology that would adversely influence participation in the protocol
• Any implanted catheter such as but not limited to CSF shunt, or the presence of pacemaker, implanted automatic internal cardioverter defibrillator (AICD, other cardiac implants and or conditions). Not including baclofen pump.
• Severe pain or hypersensitivity of the arm/hand
