Scapular Muscle Assessment in Patients with Lateral EpicondylalgiaDay, Joseph M 01 January 2013 (has links)
The role rehabilitation plays in the management of patients with lateral epicondylalgia (LE) remains elusive secondary to high recurrence rates. Addressing scapular muscle deficits may be important in the rehabilitation of patients with LE. However, it is unknown if scapular muscle impairments exist in a working population of patients with LE. The purpose of this dissertation was to assess scapular muscle strength and endurance in a working population of patients with LE.
Clinical scapular muscle assessment tools are limited in their ability to isolate specific muscles. Rehabilitative ultrasound imaging (RUSI) is a potentially useful tool but few studies have investigated its utility. Absolute muscle thickness measurements were obtained on healthy individuals for the lower trapezius (LT) and serratus anterior (SA) under three conditions (arm at rest, arm elevated with a low load, arm elevated with a high load). For both the LT and SA, a significant distinction could be made in muscle thickness between rest and a loaded condition but not between the two load conditions. Furthermore, excellent reliability was demonstrated for both muscles.
It is unknown whether arm dominance plays a role in scapular muscle assessments. Therefore, healthy individuals between the ages of 30 and 65 were recruited to compare the effect of arm dominance on scapular muscle strength, endurance, and change in thickness measured by RUSI. Results indicate that arm dominance does significantly affect some measures of scapular muscle strength and endurance. However, the differences between the dominant and non-dominant limbs were not beyond measurement error.
Scapular muscle strength, endurance, and change in muscle thickness of the LT and SA were assessed in 28 patients presenting with signs and symptoms consistent with LE. LT strength, SA strength, middle trapezius strength, endurance, and change in SA thickness were significantly less in patients with LE compared to matched controls. SA and LT strength were significantly less in the involved limb compared to the uninvolved limb in patients with LE. The results suggest that assessing scapular muscle endurance as well as LT and SA strength is indicated when evaluating patients with LE, and the results should be compared to normative data.

Effect of transverse abdominus muscle activation on a pelvic muscle exercise program in women with stress urinary incontinenceClark, Linnette 01 January 2008 (has links)
Purpose: The literature indicates that normal healthy women can increase the strength of the pelvic floor muscles (PFMs) by simultaneously contracting the transverse abdominus (TrA) muscle. This study investigated the relationship of the PFMs and the TrA in women with stress urinary incontinence (SUI). Subjects: 15 women with SUI, verified by scores on the Questionnaire of Urinary Incontinence Diagnosis (QUID), were randomly assigned, blocked by age, into 2 exercise groups. The 6 women in the PFM only group had a mean age of 63 years and the 9 women in the PFM+TrA group had a mean age of 49 years. Method: For 2 weeks, all women were trained by rehabilitative ultrasound imaging (RUSI) to correctly contract the TrA or relax the TrA during a PFM contraction depending upon the group assignment. Each woman was examined using the PERFECT scheme and prescribed a patient-specific PFM exercise program. The exercise protocols required 6 weeks of supervised patient specific exercises. Data collection occurred at 3 time periods (before intervention, after intervention, and follow-up) and included: measurement of TrA thickness changes and PFM lift by RUSI, PFM strength and endurance with pressure perineometry, number of incontinence episodes and pad use from bladder diaries, and quality of life (QOL) measurements using the Incontinence Impact Questionnaire (IIQ) and the Patient Specific Functional Scale (PSFS). Results: MANOVA identified no significant difference after interventions between groups. All women significantly improved in PFM strength (PConclusion: PFM exercises done in isolation or with recruitment of the TrA increased PFM strength, endurance, lift and decreased incontinence in women with SUI. Recommendations: Women with SUI can benefit from physical therapists prescribing PFM exercises in isolation or in combination with TrA contractions.
