High-Frequency Spinal Cord Stimulation: Revolutionizing Spasticity Management

High-frequency spinal cord stimulation produced measurable reductions in spasticity and pain in a six‑patient case series, with marked improvements in pain scores and fewer muscle spasms. This signal suggests a paresthesia‑free neuromodulation option that could complement mobility‑focused neurorehabilitation.

This contrasts with prior SCS practice: conventional, paresthesia‑based settings have typically been used to manage spasticity, whereas HF SCS delivers paresthesia‑free, high‑frequency stimulation. Crucially, these data come from a preliminary case series and do not replace randomized controlled trial evidence.

This case series enrolled six patients and targeted neuropathic pain and spasticity endpoints. The intervention produced directional and statistically significant improvements in VAS and DN4 scores, fewer clonus episodes, and reduced spasm frequency. Reported safety was reassuring: no perioperative complications or sensory or motor adverse events were observed in the cohort.

Symptom and pain reductions translated into patient‑reported motor gains—improved coordination, greater movement efficiency, and easier postural transitions—findings that may be relevant to mobility‑focused rehabilitation programs while pending confirmatory data.
