Brief summary
Primary aim of this study is to investigate wether an evidence-based physiotherapy regimen is more effective than standard care in patients referred for arthroscopic surgery of the shoulder. It is hypothesized that a multimodal physiotherapy regimen will relieve pain, improve shoulder function and reduce the need for subacromial decompression surgery of the shoulder compared to standard care/wait and see controls.
Detailed description
There has been a fourfold increase in surgery rates for non-traumatic shoulder disorders , despite increasing evidence demonstrating that there is no difference in effect between physiotherapy based- and surgical interventions. The target population for this study is patients suffering from rotator cuff tendinopathy waiting for subacromial decompression surgery at a university hospital in Norway. During this waiting period , study participants will be randomly assigned to standard follow up or a physiotherapy regimen in primary care. We want to compare the effect of a structured physiotherapy regimen consisting of heavy slow resistance exercises, stretching, manual mobilization and low level laser therapy to standard follow up.
Interventions
OTHERStructured Physiotherapy Regimen
Experimental group will be treated with heavy-slow resistance exercises targeted at the rotator cuff tendons, and exercises to improve scapular stability and strength. Glenohumeral mobilisation techniques and and stretching of glenohumeral capsule and pectoralis minor. Rotator cuff tendons and glenohumeral synovia will be irradiated with low level laser according to WALT dosage recommendations . Intervention period is 12 weeks. Three weekly treatment sessions at 0-3 weeks. 4-12 weeks one treatment session weekly , and two days of home-exercise per week.

Inclusion criteria
Patients on need for surgery ( placed at surgical waiting list at hospital or referred to surgery by their GP ) 1. Typical history with difficulties working with arms elevated over the head, and pain located in the upper segment of C5 dermatome. 2. Symptom duration of minimum 3 months. 3. Three or more reproducible signs of rotator cuff tendinopathy / subacromial impingement: * Positive isometric abduction and/or lateral rotation (Ombregt, Bisschop & Veer, 2003) * Painful arc during active abduction (Ombregt, Bisschop & Veer, 2003) * Positive Neers sign (Neer, 1972 ; Tennent, Beach & Meyers, 2003) * Positive Jobes test (Jobe & Moynes, 1982 ; Tennent, Beach & Meyers, 2003) * Positive Hawkins-Kennedy impingement test (Hawkins & Kennedy, 1980)
Exclusion criteria
1. Shoulder pain due to trauma, e.g. fall. 2. Reduced ROM consistent with adhesive capsulitis/frozen shoulder 3. History in combination with examination and tests (apprehension/relocation), giving reason to suspect pathological instability 4. Full thickness rupture of rotator cuff tendon 5. OA of the glenohumeral joint, Os acromiale with decreased space of the subacromial space, previous fractures in the shoulder complex or shoulder surgery on the symptomatic side. 6. Subjects with other comorbidity: Rheumatological or neurological disease, fibromyalgia or symptoms from the cervical spine 7. Subjects suffering from serious psychiatric illness. 8. Subjects unable to understand English or Norwegian. 9. Less than 3 positive reproducible sings of rotator cuff pathology / subacromial disease.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Need for surgery | 12 weeks (end of treatment) and 6 months post treatment | Dichotomised questionnaire yes or no |
| Shoulder function | 4 weeks , 12 weeks and 6 months | Shoulder Pain and Disability Index. 13 questions. To answer the questions, patients place a mark on a 10 point numerical scale for each question. Verbal anchors for the pain dimension are 'no pain at all' and 'worst pain imaginable', and those for the functional activities are 'no difficulty' and 'so difficult it required help'. |
| Shoulder Pain | 4 weeks , 12 weeks and 6 months | Night pain assessed on a 10 point numerical scale . Pain now and this week measured on a 10 point numerical scale . |
| Generic health status | 12 weeks and 6 months | EQ-5D questionaire. The system comprises the following 5 dimensions: mobility, self-care, usual activities,pain and anxiety/depression. he respondent is asked to indicate his/her health state by ticking (or placing a cross) in the box against the most appropriate statement in each of the 5 dimensions. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rotator cuff force | 12 weeks ( end of treatment) | Maximal painfree isometric force measurements of rotator cuff muscles using handheld dynamometry . |
| Patient global impression of change | 4 weeks, 12 weeks & 6 months | To assess global improvement a 7 point categorical scale ranging from much better to much worse is used. |
| Tendon pain pressure threshold | 12 weeks ( end of treatment ) | Tendon pressure applied over individual rotator cuff tendons with analogue algometer. Pain threshold registered in kilograms. |
| Analgesics and corticosteroid injections | 4 weeks , 12 weeks and 6 months | Analgesics consumption and corticosteroids injections registered on questionaire. |
| Tendon thickness | 12 weeks ( end of treatment ) | Ultrasonography measurements of rotator cuff tendon thickness ( subscapularis , supraspinatus , infraspinatus , biceps ) |
