Adhesive shoulder capsulitis is a pathological process in which the body creates a scar or adhesions over the glenohumeral joint, leading to pain, stiffness and dysfunction. It is a debilitating condition that can occur spontaneously (primary or idiopathic adhesive capsulitis) or after surgery or trauma to the shoulder (secondary adhesive capsulitis). The history of this condition is described as events in 3 different clinical phases: first “freezing phase” or “painful phase”, second “frozen phase” or “sticky phase” and third “thawing phase” or “regression phase”. The overall incidence of the disease is 3% to 5%, with the highest incidence between the ages of 35 and 65 with a mild prevalence in women. Patients with diabetes have an increased risk of developing idiopathic adhesive capsulitis and a higher rate of failed non-surgical treatment. Physical therapy, intervention, and procedures are the first line of treatment for this diagnosis, taking into account the symptoms and stage of the patient. Treatment includes various forms of physical therapy such as pendular exercises, manual therapy, therapy exercises, and application of numerous physical agents such as:: therapeutic ultrasound, laser therapy, transcutaneous electrical nerve stimulation (TENS), pulsed electromagnetic field therapy, interference currents, sonophoresis, ionophoresis, thermotherapy, cryotherapy, extracorporeal shock wave therapy and many others. Outcome measures that are of the utmost importance to patients need to be considered. Given the mechanism of action of electrotherapy modalities, it has been found that reducing pain and increasing range of motion are the main goals of treatment in order to improve daily life activities.
