What is Randomized Prospective Study in Patients With Complex Regional Pain Syndrome of the Upper Limb With High-Frequency Spinal Cord Stimulation (10-kHz) and Low-Frequency Spinal Cord Stimulation about?

## Objective: The objective of this prospective randomized study of cases and controls was to evaluate the efficacy of treatment with low-frequency spinal cord stimulation (lf-scs) and 10 khz spinal cord stimulation (10-khz scs) in patients diagnosed with complex regional pain syndrome type i (crps) with upper limb involvement. ## Materials and methods: Fifty patients were randomized to receive conventional treatment or scs with a commercially available low-frequency or 10-khz system. patients were assessed at 1, 3, 6, and 12 months. the primary endpoint was at 12-months post permanent implantation of the scs devices. outcome measures assessed included: numerical rating scale (nrs), 12-item short-format health survey (sf-12), oswestry disability index (odi), study sleep scale medical outcomes (mos-ss), douleur neuropathique 4 questions pain questionnaire (dn4), patient global impression scale on the impact of treatment improvement (pgi-i), clinician global impression scale on the impact of improving the patient (cgi-i). ## Results: Forty-one patients were finally included in the analysis, 19 patients in the conventional treatment group, 12 in the lf-scs group, and 10 in the 10-khz
