OBJECTIVES: Assess pateint-reported effects of transcutaneous spinal cord stimulation (tSCS) on spasticity after multiple treatment.
DESIGN: An uncontrolled prospective case series study.
SETTING: A rehabilitation hospital.
PARTICIPANTS: A convenience sample of hospitalized adults with spinal cord injury (SCI) and lower-body spasticity limiting physical function and/or reducing quality of life (i.e. pain, sleep disturbance).
INTERVENTIONS: Participants received 30 minutes of tSCS (continuous, asymmetrical, biphasic rectangular impulses, 100 Hz) applied for 3-6 consecutive days using NeuroTrac multiTENS® (http://quintet.no). Two electrodes were placed paravertebrally at Th11-Th12 level and two on lower abdomen.
OUTCOME MEASURES: Penn`s Spasm Frequency and Severity Scales were used for quantifying spasticity, Numeric Rating Scales (NRS 0-10) for perceived impact of spasticity on one chosen activity of a daily living, sleep-disturbance, and pain in trunk/lower limbs due to spasticity. The outcome measures were completed through interviews conducted before the first treatment, and immediately after the last treatment.
RESULTS: Seventeen people participated; injury levels C6-T12, AIS A-D, and mean age 51 years (SD 14). Fourteen participants reported a clinical important improvement in ADL performance, sleep disturbance and/or a decrease in pain due to spasticity (≥ two points on NRS). Minimal change was reported on Penn`s Spasm frequency and Severity Scales. No adverse events were observed.
CONCLUSIONS: The majority of the participants perceived clinically relevant improvements on at least one patient-reported outcome measure, and no adverse events were reported. This is a simple and a non-invasive treatment that may have a potential of reducing the troublesome effects of spasticity.
