Subacromial Impingement - The Need of Arthroscopic Subacromial Decompression After Eccentric Physical Therapy Exercises

June 16, 2011 updated by: Linkoeping University

Does the Need of Arthroscopic Subacromial Decompression Change After Eccentric Physical Therapy Exercises in Patients With Subacromial Pain? - A Randomized Clinical Trial

Objective:

A randomized clinical trial in order to evaluate the efficacy of structured eccentric exercises tutored by a physical therapist (PT) for patients with subacromial impingement.

Hypothesis:

H1 The exercises has a satisfactory effect and the need of an arthroscopic subacromial decompression can be reconsidered.

H0 No difference between the two exercises (experimental and active control) and the patients still need surgery

Further the study objective is to evaluate predictors for a positive or negative treatment response after three months of rehabilitation as well as after 12 months.

Method:

Patients referred to the orthopedic unit for an arthroscopic subacromial decompression, are offered a three month rehabilitation program during the waiting time for surgery which is approximately 4-6 months. All patients must have tried conservative treatments for at least 6 months in primary care with unsatisfactory results. The patients will be randomized to either the structured eccentric exercises tutored by a physical therapist or control exercises with general movements for the neck and shoulders. All patients has an equal number of sessions with the PT to offer similar attention. After three months the following key-question has to be answered: due to your current experience of your shoulder problems do you still need this surgical intervention? A blinded orthopedic surgeon evaluates the following outcomes at baseline and after three and twelve months. Primary outcomes: Constant-Murley shoulder assessment, Disabilities of the Arm Shoulder and Hans and different aspects of pain. Secondary outcomes; EQ-5D, sick-leave and return to work. All patients are evaluated with a diagnostic ultrasound in order to reveal the condition of the rotator cuff. Also long-term results in those who go thorough with the surgery and those who decline will be assessed after 12 months.

Importance of the study results:

Since there is no consensus about which intervention that should be preferred for patients with subacromial impingement the results of the current study is warranted. If this exercise program is successful it can be implemented into clinical practice. Further, clinical characteristics of patients that really need an arthroscopic subacromial decompression can be identified.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Constant-Murley shoulder assessment
Time Frame: Baseline and change after three months of exercises, 3 month follow-up

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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
