About this study

Official title: Allowing Pain Versus Avoiding Pain During Shoulder Exercises: Does Pain Matter in the Effectiveness of an Exercise Program in Patients With Rotator Cuff Tendinopathy?

Overuse shoulder injuries such as rotator cuff (RC) tendinopathy are common with a prevalence estimated to be 14% in the general population of which 23% of the working population with shoulder problems are sick listed.

RC tendinopathy is a tendon-related pain in the proximal lateral aspect of the upper arm with weakness, especially during active elevation and external rotation, and painful active range of motion. The prevalence of RC tendinopathy is highest in the supraspinatus and infraspinatus tendon.

Exercise therapy is regarded as an effective intervention for symptomatic RC tendinopathy for reducing pain and disability and improving function. However, the prescription is diverse and the effectiveness of specific characteristics of exercise programs is unknown. Many contextual factors and prescription parameters, such as external resistance, training intensity and frequency, home versus supervised exercises, duration of the program, etc. have been described. Some of these prescription parameters have been extensively studied, with some conflicting results. Although some level of resistance seems to matter, as well as number of sets and repetitions, the 'optimal' level and volume are unclear. Inducing or allowing pain based on tendon loading during exercises is todays consensus in the treatment of patellar and achilles tendinopathy using a pain-monitoring model. Although a number of shoulder studies report that pain either should be avoided or allowed, not one study ever examined the influence of pain allowance versus pain avoidance during a shoulder exercise program on patient outcome in terms of pain, physical function and disability.

The purpose of this project is to examine the effect of allowing pain versus avoiding pain based on tendon loading during an exercise regimen for patients with symptomatic rotator cuff (RC) tendinopathy. This will be accomplished in a Randomized Controlled Clinical Trial, comparing the effectiveness on patient reported and objective outcomes of a "pain allowing" and "pain avoiding" exercise program, performed for 26 weeks. Our hypothesis is that allowing pain based on tendon loading during exercises would result in a better outcome in pain and function measured on SPADI (the primary outcome) compared to avoiding pain in patients with RC tendinopathy.

Aim The purpose of this project is to examine the effect of allowing pain versus avoiding pain based on tendon loading during an exercise regimen for patients with symptomatic rotator cuff (RC) tendinopathy. This will be accomplished in a Randomized Controlled Clinical Trial, comparing the effectiveness on patient reported and objective outcomes of a "pain allowing" and "pain avoiding" exercise program, performed for 26 weeks.

Background Shoulder disorders are the third most common musculoskeletal disorder with a life-time prevalence in the general population of 30%. Shoulder disorders are often persistent and recurrent, with 54% of the patients reporting on-going symptoms after 3 years. RC tendinopathy is regarded as a common source of shoulder pain with prevalence estimated to be as high as 14% in the general working-age population. About 23% of the working population with shoulder problems are sick-listed, with a potential individual productivity loss.

RC tendinopathy is a tendon-related pain in the proximal lateral aspect of the upper arm with weakness, especially during active elevation and external rotation, and painful active range of motion. The pathoanatomic understanding is extended by classifying tissue irritability and specific impairments. Tissue irritability is meant to guide intensity of treatment, and identifying specific impairments guides specific tactics used for intervention. The prevalence of RC tendinopathy is highest in the supraspinatus and infraspinatus tendon.

Exercise therapy is widely regarded as an effective intervention for symptomatic RC tendinopathy for reducing pain and disability and improving function. It is well known that tendon collagen regains formation and tensile strength faster than unstressed collagen, and that it can take 12 month or longer before it reaches full maturity and strength. However, the prescription is diverse and the effectiveness of specific characteristics of exercise programs is unknown. Many contextual factors and prescription parameters, such as external resistance, training intensity and frequency, home versus supervised exercises, duration of the program, etc. have been described and are summarized in a systematic review. Some of these prescription parameters have been extensively studied, with some conflicting results. Although some level of resistance seems to matter, as well as a number of sets and repetitions, the 'optimal' level and volume are unclear. The existing studies offer some preliminary guidance in relation to the development and application of loading in exercise programs for RC tendinopathy, however there is a gap in literature with respect to allowing or avoiding pain during shoulder exercises. Inducing or allowing pain based on tendon loading during exercises is todays consensus in the treatment of patellar and achilles tendinopathy using a pain-monitoring model.

Although a number of shoulder studies report that pain either should be avoided or allowed, not one study ever examined the influence of pain allowance versus pain avoidance during a shoulder exercise program on patient outcome in terms of pain, physical function and disability.

Hypothesis Allowing pain based on tendon loading during exercises would result in a better outcome in pain and function measured on SPADI (the primary outcome) compared to avoiding pain in patients with RC tendinopathy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pain Allowing Program (PAllow)Behavioural

    Performing exercises considered to have a considerable supraspinatus/ infraspinatus tendon/muscle load (EMG muscle activity of > 40% MVC).

  • Pain Avoiding Program (PAvoid)Behavioural

    Performing exercises selected to have a minimal insupraspinatus/ infraspinatus tendon/muscle load (EMG muscle activity of <20% MVC).

    These unloading exercises are performed for 6 weeks. In the second part of the exercise protocol, the "loading" exercises are applied, however without pain.

    In case the patient still feels pain during the exercises in that period, the "unloading" exercises are continued.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline in Shoulder Pain and Disability Index (SPADI)

    Self-reported measure of pain and function. The responses are indicated on a visual analogue scale where 0 = no pain/no difficulty and 10 = worst imaginable pain/so difficult it requires help. The items are summed and converted to a total score out of 100 where a high score indicates greater pain and disability in patients with shoulder disorders.

    Measured: 26-week

Secondary outcomes (7)
  1. Change from baseline in Shoulder Pain and Disability Index (SPADI)

    Self-reported measure of pain and function. The responses are indicated on a visual analogue scale where 0 = no pain/no difficulty and 10 = worst imaginable pain/so difficult it requires help. The items are summed and converted to a total score out of 100 where a high score indicates greater pain and disability in patients with shoulder disorders.

    Measured: 52-week

  2. Change from baseline in Disabilities Arm, Shoulder and Hand questionnaire (DASH)

    Self-reported measure of pain, function and quality of life. The questionnaire score ranges from 0 to 100 where 0 equals no disability and 100 equals the most severe disability.

    Measured: 26 and 52 weeks

  3. Change from baseline in Numeric Pain Rating Scale (NPRS)

    Self-reported measure of pain. The score ranges from 0 to 10 where 0 equals no pain and 10 equals the most severe pain.

    Measured: 26 and 52 weeks

  4. Patient Acceptable Symptom State (PASS)

    Self-reported measure of symptom acceptability. The PASS threshold is determined by asking patients if they are satisfied with their current health state. Patients respond to this question with "yes" or "no".

    Measured: 6, 26 and 52 weeks

  5. Global Rating Scale (GRS)

    Self-reported measure of change of condition. The GRS is used to obtain a general impression of recovery from baseline to 26 and 52 weeks after baseline with the question: "Compared to when this treatment first started, how would you describe your shoulder this last week?" This is assessed on a 15-point scale where - 7 represents vastly worse, 0 represents unchanged, and + 7 represents much better.

    Measured: 6, 26 and 52 weeks

  6. Change from baseline in Range-of-motion (ROM) in scapular plane elevation (standing) and in external (supine in 90° abduction)

    Objective measure

    Measured: 26 and 52 weeks

  7. Change from baseline in Isometric muscle strength (MVC) in shoulder elevation in scapular plane and external shoulder rotation

    Objective measure

    Measured: 26 and 52 weeks
