The incidence of frozen shoulder in the general population is approximately 5%, however, due to a lack of clear diagnostic criteria, the true incidence and prevalence rates are unknown. Clinically, frozen shoulder is associated with diabetes, thyroid disorders, cardiovascular disease and Dupuytren disease. Nevertheless, a significant number of frozen shoulder cases are diagnosed as idiopathic in nature and therefore, treatment largely focuses on symptom modification and functional enhancement.
 
Recent systematic reviews have demonstrated an association between pain related beliefs and disability in shoulder pain patients. As well, pain self-efficacy appears to be an important factor associated with arm function for patients who received physiotherapy for their shoulder complaint. This demonstrates a link between confidence in performing a task and a person’s perceived function.
 
As a result of the (often) long-lasting pain and dysfunction in patients with frozen shoulder, it is of interest to understand the role of protective versus unhelpful pain-related beliefs underlying reduced arm function. Within the Fear Avoidance Model, a painful experience is believed to initiate catastrophic thoughts about pain, resulting in pain-related fear and avoidance behavior. This avoidance behavior can then, of course, lead to decreased function.
 
The primary aim of this study is to explore the association between pain-related beliefs and perceived arm function in patients with frozen shoulder. Secondarily, this study set out to also understand the role pain-related beliefs play in the variance of perceived arm function in patients. It was hypothesized that a significant portion of the variance will be linked to pain-related fear, catastrophizing and pain self-efficacy…LOG IN OR SUBSCRIBE TO ACCESS THIS REVIEW!
