Effects of position-triggered electrical stimulation on poststroke hemiparetic shoulder subluxation

BACKGROUND: Shoulder subluxation is a frequent complication after stroke causing joint instability, shoulder pain, decreased activities of daily living, and impedance to rehabilitation progress. Electrical stimulation (ES) considered an effective modality reduce in acute stroke. However, few studies have investigated the effect position-triggered ES, which induces active muscle contraction though accurate motion detection.AIM: The aim this study was investigate whether ES more reducing hemiplegic than passive ES.DESIGN: Single-blind, randomized controlled trial.SETTING: setting university hospital center.POPULATION: Fifty poststroke subacute hemiparetic patients with subluxation.METHODS: Patients were randomly assigned into two groups. group received 30-minute sessions, 5 days per week for 3 weeks specially modified Novastim® CU-FS1 (CU Medical Systems, Inc., Gangwon-do, South Korea) triggering. same protocol without vertical distance (VD) (JD), relative VD JD (rVD, rJD), upper extremity component Fugl-Meyer Motor Assessment (FMAupper), Motricity Index (MI), Manual Function Test (MFT), peak torque affected abductor (PT) assessed at baseline (T0), end electrical session (T1), (T2) treatment.RESULTS: Repeated-measures analysis variance revealed significant interaction between time intervention on rJD, indicating that significantly reduced (P<0.05). FMAupper, MI, MFT, PT did not show significance. change (∆)JD, ∆rVD, ∆rJD motion-triggered improved T1 This improvement seen T2.CONCLUSIONS: Position-triggered may be improving subluxation; however, maintained withdrawal stimulation.CLINICAL REHABILITATION IMPACT: useful subluxation.
