Assessments at baseline, post intervention and follow-up will include physical activity (self-report and accelerometry), a battery of functional performance measures, functional limitations, quality of life, and an array of psychological health measures.
We used two disability measures: functional limitations due to emotional health measured on the SF-12, and problems with activities in daily living (ADL) indicating limitations in five domains (personal help, transport, medical help, household activities and money).
We measured functional limitations using the following performance-based rheumatology function tests: 1. Grip strength.
It was intended to measure functional limitations of the affected shoulder in patients with common shoulder problems, including rotator cuff tears, degenerative osteoarthritis, and instability [ 25].
This is especially evidenced by the results that substantial ceiling effects were more frequently encountered in scales measuring functional limitations (e.g. PF, RP, and RE).
Although they can be measured in a number of different ways, we have chosen to use performance-based functional tests such as the grip strength, walking velocity and the timed shirt-button test to measure functional limitations [ 11].
By including a total number of 223 patients and having 212 patients available for analyses, sufficient power was assured for the comparison between the three active treatments and the WL regarding the primary outcome measure, functional limitations.
The Manchester Foot Pain and Disability Index (MFPDI, 19 items) was developed to measure functional limitations, pain and appearance for patients with foot pain and is frequently used in both observational studies and randomised controlled trials.
The patient self-report section of the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES, 0 100 points, 100 = best result) was utilized as an outcome tool to measure functional limitations and pain in the shoulder.
