A RANDOMISED CONTROLLED TRIAL OF TREATMENT OF THE PAINFUL ARC OF THE SHOULDER – TPARC

Newcastle Hospitals NHS Trust, Newcastle-upon-Tyne, UK

The aim of this randomised, controlled trial is to compare subacromial steroid injections, physiotherapy and both interventions with a control treatment in early painful arc of the shoulder.

Over a six-month period patients with "painful arc", of less than six months duration, were recruited via their GPs. Eligible patients were consented to enter the trial and were then randomised, by sealed envelopes, to one of four arms of the study: control (normal analgesia and/or non-steroidal anti-inflammatory medication), a specified and repeatable Exercise and Manual Therapy Package (EMTP), a course of up to three subacromial steroid injections or both the EMTP and the steroid injections. The interventions and clinic follow-ups were over an 18-week period. A final postal questionnaire was sent out at one year. The progress of the patients was monitored using the Oxford Shoulder Score (OSS) and the SF36 general health questionnaire.

Seventy-nine GPs referred 186 patients, of whom 112 were randomised (Control=27, EMTP=29, Injections=28, Both=28). 64 patients were female and 48 male. The mean age was 54.5 years (range 23–88 years). Ninety patients completed the trial (Control=20, EMTP=22, Injections=26, Both=22). Sixty-two returned the follow-up questionnaire. By paired sample t-tests, no significant differences were found between the OSS scores or SF-36 (physical health total) at the beginning and end of the intervention period, or at one year. Two patients in the injection group went on to surgery, along with one each in the control and EMTP groups.

We have found no significant differences in outcome between steroid injections, a physiotherapy package, both treatments, or symptomatic treatment in our group of patients presenting with symptoms of painful arc of the shoulder.
