Abstract
BackgroundThe wiper exercise in a side-lying position is commonly used in clinical settings to assess the strength of the infraspinatus muscle. In addition, a reliable test of infraspinatus strength is important for individuals with scapular dyskinesis.ObjectiveThe purpose is to compare the test-retest reliability of infraspinatus strength during the wiper exercise with and without external fixations in individuals with scapular dyskinesis.MethodsThirty individuals with scapular dyskinesis participated. A dynamometer was utilized to measure the strength of the infraspinatus during the wiper exercise with and without external fixation applied to the posterior superior iliac spine (PSIS) and spinous process of a fourth thoracic vertebra (T4). The intra-class correlation coefficients (ICC 3,1) were used to compare the reliability of infraspinatus strength measurement.ResultsThe reliability for infraspinatus strength measurement was higher with external fixation than without external fixation. The ICC value during wiper exercise with external fixation was 0.99 (95% confidence interval: 0.96-0.99; P < 0.01), and the average strength was 7.35 ± 2.2 kg. In contrast, the ICC value during wiper exercise without external fixation was 0.79 (95% confidence interval: 0.49-0.93; P < 0.01), and the average strength was 5.86 ± 1.45 kg.ConclusionIn individuals with scapular dyskinesis, the infraspinatus strength measurement during the wiper exercise with external fixation is recommended to improve the test-retest reliability.
期刊介绍:
The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty.
In each issue clinicians can find information which they can use in their patient setting the very next day.
