Summary

The successful application of treatment protocols using motion-triggered neuromuscular electrical stimulation (NMES) for treatment-resistant functional posterior shoulder instability was recently demonstrated. The purpose of this study is to evaluate the concept of a motion-triggered NMES training protocol through objective clinical outcome parameters and its impact on external rotational (ER) shoulder strength and throwing velocity in healthy, elite-level handball players.

Conditions

  • Shoulder Dislocation

Interventions

Motion-triggered NMES training protocol

Experimental group subjects undergo a motion-triggered NMES shoulder strengthening training program (3x/week, 30 minutes for 6 weeks) using the Shoulder Pacemaker (NCS Lab Srl, Modena, Italy), a motion activated stimulation device to strengthen muscular disbalances. This is accomplished through varying neuromuscular electrical stimulation intensity based on the angle of motion of the arm producing subtetanic contraction and provoking supraspinal neural adaptations. Electrode placement: electrode 1, inferior to the scapular spine (infraspinatus, teres minor, + posterior deltoid); electrode 2, medial to the medial scapula border (lower trapezius + rhomboids) . Sets x repetitions: 3x20 Levels: Level 1-3; Exercise 1: L1: Supported row, L2: Front raises in 45°, L3 Front raises (thumbs up) Exercise 2: L1: Resisted front raises, L2: Crossbody resisted raises, L3: Crossbody; forehand swing; Exercise 3: L1: Rear dealt fly, L2: Single arm resisted row, L3: Underhand volleyball

OTHER

Non-Motion-triggered NMES training protocol

Arm Description: Subjects of the control group undergo a conventional standardized strength training program (3x/week, 30 minutes for 6 weeks) with concentric, eccentric, and functional training exercises.
