Background: Postural changes after unilateral mastectomy may appear in relation to the dominant hand, postoperative duration, and dynamic conditions. This study aimed to compare the postural changes by inclination angles and muscle activities in the static and dynamic sitting position between women with breast cancer who underwent mastectomy and women who did not have breast cancer.Methods: The observational study design was conducted. We evaluated 17 women who underwent modified radical mastectomy (MRM) more than 1 year prior to the study. They were categorized into the Rt. mastectomy group (n=7) and the Lt. mastectomy group (n=10). An aged-matched cohort of 8 healthy females was also included. The inclination angle in both static and dynamic sitting positions was measured using the balance board system (BBS), and the muscle activities of 8 muscles were measured in the dynamic sitting position.Results: There was no significant difference in demographic characteristics between the patients, and all patients were right-handed. The inclination angle of the anterior-posterior axis when leaning forward was significantly increased to the anterior side in the Rt. mastectomy group than in the Lt. mastectomy group.Meanwhile, the inclination angle in the static sitting position and when tilted backward to both directions did not differ among the 3 groups. The inclination angle of the right-left axis was statistically increased to the left side during tilting anterior-left direction in the Rt. Mastectomy group. The muscle activities of the thoracic erector spinae were significantly lower when tilted backward in the Rt. mastectomy group than in the Lt. mastectomy group. Conclusions:Compared with left mastectomy, right unilateral mastectomy yielded more postural changes under dynamic sitting state in right-handed female patients with breast cancer. Thus, to maintain the trunk balance and prevent the postural changes after unilateral mastectomy, the postoperative exercise programs for the para-thoracic muscles will be helpful.

“…Recent articles indicate that one-sided mastectomy or minor breast surgery to treat breast cancer can have deleterious effects on posture and the musculoskeletal system such as alterations in spine alignment, an increased thoracic kyphosis and upper limb dysfunctions, and decrease of shoulder joint angles at the operated side, 4 but other studies appear to contradict these statements. 1,5 After breast cancer surgery, patients have reduced physical participation in valuable activities contributed, more specifically, to explaining variability in depression. 6 The patient tends to assume an attitude of closure, especially versus the presurgery “protective posture.” In the early stages after surgery, this attitude is also due to modesty and shyness.…”

Breast cancer is the most common malignant tumor in female patients in developed countries. Recent articles indicate that one-sided mastectomy or minor breast surgery to treat breast cancer can have deleterious effects on posture and the musculoskeletal system. The purpose of this study was to investigate the alterations post-breast cancer surgery of the spine alignment associated to the balance not reported by the noninvasive instrumentation. We enrolled 30 women who had undergone treatment for breast cancer (BG) and were on a waiting-list for rehabilitation treatment and a control group of 30 healthy volunteer women (CG), matched by age and body mass index. The stabilometry was performed using a force platform (Kistler Instruments, Winterthur, Switzerland) test during quiet standing with closed-eyes (EC) and open-eyes (EO), recording the position of the center of pressure (CoP) for 51.2 sec. The stabilogram or the time plot of the two coordinates, X and Y, of the CoP was obtained, which represent anteroposterior and midlateral balance. Spinal posture was measured using the Formetric-4D rasterstereographic system (DIERS, International GmbH, Schlangenbad, Germany), and thoracic kyphotic angle, lumbar lordotic angle, and surface trunk rotation were evaluated. Sixty participants were analyzed (CG:30; BG:30). For the spine rasterstereography a statistically significant difference was shown with regard to anterior–posterior flexion of the trunk major in BG; pelvic inclination and twist of half-pelvis decreased in BG; normalized lumbosacral inversion point decreased in BG; surface rotation major in BG; and lateral deviation major in BG. Compared with the values for the stabilometry test with EO and EC, a statistically significant difference was observed, respectively, for ellipse length (mm; p = 0.04) and ellipse area (mm 2 ; p = 0.04) with EO and in ellipse area (mm 2 ) with EC ( p = 0.05), increased in BG for both conditions. No difference was shown for CoP velocity and oscillations between the groups. Breast cancer survivors after prostheses or tissue expanders for mastectomy showed a spine's misalignment present both on the sagittal plane, both on the coronal and frontal plane, increased in BG regard to anterior–posterior flexion of the trunk, surface rotation, and lateral deviation. It is associated with greater energy expenditure for the postural balance control increased in BG with a major ellipse area in EO and EC conditions and major ellipse length in EC condition.

“…The question whether EBP influences the postural stability of women who underwent mastectomy was not answered by the previous studies. Moreover, the literature on the subject indicates that the EBP does not play such a significant role as it could be assumed in the postural control of women who underwent unilateral mastectomy ( 11 , 28 , 30 ). Karczewska et al., based on studies assessing the influence of external prostheses on the dynamic balance of women who underwent unilateral mastectomy, found that the breast prosthesis did not affect the quality of equivalent reactions in the dynamic study ( 24 ).…”

Background:Women after mastectomy may decide to either have a breast reconstruction or use an external breast prosthesis. Aim: The aim of the presented research was to evaluate the influence of external breast prosthesis on postural stability in women after mastectomy. Methods and Procedures: In the study 52 women after unilateral mastectomy took part. The study consisted of 4 parts: 1) anthropometric measurements; 2) measurements of upper limb circumference; 3) assessment of weight-bearing (WB); and 4) posturographic tests (PT). Outcomes and Results: Differences in the arm circumferences on the amputated (A) and non-amputated (NA) sides did not confirm the occurrence of lymphedema in limb on amputated side. The results of the WB between the A and NA body sides in both tested conditions, i.e., with open and closed eyes, showed no significant differences between the test with and without an external prosthesis. No statistically differences have been observed between posturometric parameters with and without breast prosthesis during both PT. In comparing the posturometric parameters between the PT with open and closed eyes, the sway path of the center of pressure was statistically significantly longer when eyes were closed in both conditions, i.e., with and without breast prosthesis. Conclusion and Implications: The finding show that 1) external breast prosthesis does not have a significant influence on the symmetry of loading on the A and NA body sides and on the postural stability of women after unilateral mastectomy and 2) exclusion visual control during PT increases postural instability in women after unilateral mastectomy.
