SWESS: The SWedish Exercise Shoulder Study in Primary Care for Patients With Subacromial Pain

Not Applicable

Completed

• Conditions: Shoulder Pain; Shoulder Impingement Syndrome; Disorder of Rotator Cuff; Subacromial Bursitis

• Registration Number: NCT01885377
• Lead Sponsor: Linkoeping University

Brief Summary

Objective: A randomized clinical trial in order to evaluate the efficacy of a specific exercise strategy for patients with subacromial pain.

Hypothesis:

H1 - The three month specific exercise strategy has a satisfactory effect improving shoulder function and/or shoulder pain.

H0 - No difference between the two exercise strategies (specific exercise strategy and active control exercises).

Method: Patients attending primary care with subacromial pain are offered participation. If accepted, they will participate in a three month rehabilitation program. The duration of symptoms can vary from 2 weeks and longer. The patients will be randomized to either rehabilitation; the specific exercise strategy or active control exercises. All patients has an equal number of sessions with the physical therapist (PT) to offer similar attention and support with exercise performance. A blinded physical therapist evaluates the following outcomes at baseline and after three-, six and twelve months:

Primary outcomes: Constant-Murley shoulder assessment (CM-score). Secondary outcomes; Disabilities of the Arm Shoulder and Hand questionnaire (DASH), different aspects of pain by Visual Analogue Scale (VAS), EuroQol-5D index (EQ-5D) and EuroQol-VAS (EQ-VAS), The Patient Specific functional Scale, and Patients' global impression of change (PGIC). Also sick-leave and return to work will be recorded. All patients are evaluated with a diagnostic ultrasound to reveal the status of the rotator cuff.

Additional to the analysis of treatment effect on shoulder function and pain, factors influencing and explaining the CM-score at follow-ups will be analyzed.

This study is warranted in order to evaluate if an earlier reported positive effect on shoulder function and pain with the specific exercise strategy, in patients on waiting list for subacromial decompression, can be repeated in the primary care population of patients with subacromial pain. There is no consensus about first-line exercises for patients with subacromial pain, and these positive results on pain and shoulder function need to be reproduced in primary care before they can be recommended and implemented. Further, knowledge about which factors that can be used in prediction rules for patients that will respond to the exercises or needs surgery is lacking.

Detailed Description

This study will be reopened and will continue the inclusion due to underpowered results.

A new application to the Ethical committee was submitted. Approval to reopen this RCT-study was received at 27th of September 2018 (dnr 218/445-32).

Additional inclusion of 40 additional patients will start at 1th of November 2018. Data from baseline to 12 months follow-up (as described in protocol) will be collected. Inclusion continued and the last inklusion was completed in February 2020. Data Collection for all follow ups is anticipated to be completed at latest during March the year of 2021.

Primary Outcome Measures

Name	Time	Method
The Constant-Murley shoulder assessment	Baseline and change 3-, 6- and 12 months	Measure a combination of self assessed and clinician assessed items; pain, range-of-motion (flexion and abduction), functional positions (hand in neck as well as hand in back), abduction strength.; The score is summarized to a maximum of 100 for best available shoulder function.

Secondary Outcome Measures

Name	Time	Method
Euro Qol 5D index (EQ 5D)	Baseline and change 3-, 6- and 12 months	Health Related Quality of Life by EuroQol 5 dimensions and index. Measures different items related to heath related quality of life: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. It results in a health-state where an index of 1 is optimal.
VAS for pain	Baseline and change 3-, 6- and 12 months	Self-assessed for pain at rest, in activity and at night if it disturbs sleeping
The Patient Specific functional Scale	Baseline and change 3-, 6- and 12 months	Self-selected functional activities to relate efficacy to during follow-ups.
Disabilities of the arm, shoulder and hand	Baseline and change 3-, 6- and 12 months	Self-assessment of the ability to performed exemplified activities. 0 indicates a non-affected upper extremity.
Euro Qol VAS (EQ VAS)	Baseline and change 3-, 6- and 12 months	In EQ VAS the patients assess their health state on a vertical line valued from 0-100.
Patients Global Impression of Change (PGIC)	At follow-up: 3-, 6- and 12 months	The patients are asked to assess change. A scale ranging from getting worse by the intervention to be recovered.
