Ultrasonographic assessment of neuromuscular electrical stimulation efficacy on glenohumeral subluxation in patients with hemiplegia: a randomized-controlled study.

OBJECTIVES

This study aims to investigate the short-term effects of neuromuscular electrical stimulation (NMES) on glenohumeral subluxation (GHS) in stroke patients.

PATIENTS AND METHODS

This prospective, randomized-controlled study included 24 unilateral hemiplegic patients (10 males, 14 females; mean age 64.1±14.8 years; range 22 to 84 years) with GHS as assessed by ultrasonography between December 2013 and September 2014. The patients were randomly divided into two groups as those in the NMES group (n=12) who were treated with NMES to supraspinatus, upper trapezius, and posterior deltoid muscles combined with conventional physiotherapy and as those in the control group (n=12) who were received conventional physiotherapy alone. Clinical (the Brunnstrom Motor Recovery Stage, Visual Analog Scale [VAS] for Pain and Shoulder Disability Questionnaire [SDQ]) and ultrasonographic (acromion-greater tuberosity distance, thicknesses of supraspinatus, upper trapezius, and posterior deltoid muscles) variables were evaluated before and after treatment in both groups.

RESULTS

The SDQ index, acromion-greater tuberosity distance, and supraspinatus muscle thickness were improved in the NMES group, compared to the control group (for all p<0.05). The VAS-pain scores decreased in both groups. There was no statistically significant alterations in the other measurements in both groups (for all p>0.05). The percentage change (%) of the VAS-pain scores was not significantly different between two groups (p=0.03).

CONCLUSION

Our study results showed that GHS decreased after 20 sessions of NMES treatment. Based on these findings, ultrasonography appears to be a proper imaging tool for the evaluation of GHS in stroke patients.
