Outcomes of Treatment Using the ERMI Shoulder Flexionater ®

Study 1 - Adhesive Capsulitis Study (AC)

Objective: The purpose of this study is to compare treatment efficacy of patients with symptoms of primary and secondary adhesive capsulitis between three groups: 1) Patients treated with Physical Therapy alone; 2) Patients treated with the ERMI Shoulder Flexionater® alone; 3) Patients treated with PT + Device in the treatment.

• Prospective randomized control trial
• Sample size - 110 patients
• Study Groups:

• Group I - Physical Therapy Only
• Group II - Flexionater® only
• Group III - Flexionater® and Physical Therapy
• Length of study - 2-year follow-up from last enrolled patient

Study 2 - Postoperative Shoulder Stiffness Study (POS)

Objective: The purpose of this study is to compare treatment efficacy of patients with post-operative stiffness indicative of secondary adhesive capsulitis between three groups: I) Patients treated with Physical Therapy alone; II) Patients treated with the ERMI Shoulder Flexionater® alone; III) Patients treated with PT + Device in the treatment.

• Prospective randomized control trial
• Sample size - 90 enrolled patients
• Study Groups:

• Group I - Physical Therapy only
• Group II - Flexionater® only
• Group III - Flexionater® and Physical Therapy
• Length of study - 2-year follow-up from last enrolled patient

Study 3 - Secondary Surgery Study (SAM)

Objective: The purpose of this study is to compare recovery of patients who have undergone a manipulation under anesthesia or a lysis of adhesions between three groups: 1) Patients treated with Physical Therapy alone; 2) Patients treated with the ERMI Shoulder Flexionater® alone; 3) Patients treated with PT + Device in the treatment.

• Prospective randomized control trial
• Sample size - 10 enrolled patients
• Study Groups:

• Group I Physical Therapy Only
• Group II - - Flexionater® only
• Group III - Flexionater® and Physical Therapy
• Length of study - 2-year follow-up from last enrolled patient
