Shocking spasticity: new trial zaps arm stiffness with targeted pulses
NCT ID NCT07321158
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a short burst of electrical stimulation to the arm muscles can reduce spasticity—stiffness and tightness—in people who have had a stroke or other brain or spinal cord injury. About 45 adults with upper limb spasticity will be randomly assigned to receive either high or low pulse duration electrical stimulation, or standard care alone. Researchers will measure changes in muscle activity, range of motion, and daily function to see which approach works best.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * diagnosis by neurologist with first damage of pyramidal tract with upper limb spasticity * absence of cognitive dysfunction * normal vital signs * absence of pharmacological treatment of spasticity (per os pharmacological treatment does not affect spasticity results and was not an exclusion criteria on patients' recruitment). Exclusion Criteria: * prior neurological damage to pyramidal tract * cognitive decline * dermatological damages * prior musculoskeletal dysfunction on the upper limb with spasticity * presence of metallic residues on the spastic upper limb * presence of seizures or psychiatric disorders * severe malformation or obesity (BMI \>30kg/m2) * history of coronary or other cardiovascular diseases (deep vein thrombosis, pulmonary embolism) * presence of systematic inflammatory disease * cancer on terminal stages * pregnancy.
