Effects of Mastectomy on Shoulder and Spinal Kinematics During Bilateral Upper-Limb Movement

Abstract: The findings suggest that altered motor patterns of the scapula are associated with mastectomy on the same side. Whether these changes are harmful or not is unclear. Investigation of interventions designed to restore normal scapulohumeral relationships on the affected side following unilateral mastectomy for breast cancer is warranted.

“…The rate of self-reported affected upper limb weakness exceeding strength measures in this cohort is in agreement with other research [37,46]. We did not assess strength of the scapular stabilizing muscles but recognize that weakness of the stabilizing muscles rather than the primary shoulder muscles may contribute to the self-reported weakness as reduced scapular muscle strength and altered scapular mechanics have been reported after breast cancer surgery [47][48][49][50]. Reduced muscular endurance rather than strength deficits may also contribute to persistent self-reported weakness [51].…”

“…In previous studies, 30% (Gärtner et al, 2009) and 48% (Hopwood et al, 2010) of breast cancer survivors had upper extremity pain two and five years post-surgery. DASH was mean 10-13 six to 12 months post-breast cancer surgery (Hayes, Battistutta, & Newman, 2005; n = 258, Crosbie et al, 2010; n = 53).…”

“…For absolute reliability, the SEM and the smallest real difference (SRD) were calculated. SEM is described as the square root of the within participant variance: SEM = SD √ 1-r. For inter-rater reliability, a SRD value of less than 1.96 × SEM is expected to admit the results of 95% of the ratings 17) In the intra-rater reliability and test-retest reliability, the SRD should be less than √2 × 1.96 × SEM = 2.77 × SEM for 95% of the pairs of ratings to be significant 18) . The statistics were performed using SPSS ver.…”
