Structured Rehabilitation Program for Multidirectional Shoulder Instability in a Patient with Ehlers-Danlos Syndrome

Patients with Ehlers-Danlos syndrome (EDS) present many musculoskeletal disorders. The purpose of this case report was to describe the effectiveness of a scapular motor control program for a patient with multidirectional severe shoulder instability due to EDS, with 6-month follow-up. The patient was a 14-year-old female with EDS hypermobile type who suffered recurrent shoulder dislocation. Her chief complaints were bilateral shoulder discomfort and instability during writing motion. In the early part of intervention, she was prescribed exercise therapy for multidirectional instability (MDI) with orthosis. In the latter part of intervention, she was instructed in the scapular motor control program. Active and passive range of motion (ROM), sulcus sign, and Rowe score for shoulder instability were measured at baseline and at 3, 6, and 12 months after interventions. The shoulder ROM and instability score were improved after 6-month intervention. The findings from this report indicate that the scapular motor control program for shoulder instability would be effective even for patients with EDS hypermobile type. A patient who could not increase passive ROM due to dislocation is also able to achieve fair function of the shoulder joint instead of increasing active ROM. These positive outcomes indicate the possibility of benefit from the scapular motor control program for an MDI patient with EDS as a conservative treatment.
