4Study Design: Exploratory. Objectives: To explore whether hand dominance, gender, and body mass index (BMI) influence the thickness of the lateral abdominal muscles as measured by ultrasound imaging. To document the extent of improvement in response stability when an average of multiple measures was utilized. Background: Ultrasound imaging is a relatively new tool used to assess the lateral abdominal muscles. A better understanding of how these muscles contract in a healthy population can provide a reference for comparison to patients with low back pain (LBP). Methods and Measures: Thirty-two healthy participants (17 males, 15 females) aged 18 to 45 years (mean ± SD, 31.9 ± 7.8 years) were studied. Measurements of muscular thickness of the lateral abdominal muscles were obtained bilaterally while the subjects were at rest, and while they performed the abdominal drawing-in maneuver. To determine the possible influence of hand dominance and gender on muscle thickness, t tests were used. Correlation coefficients were used to assess the relationship between BMI and muscle thickness. Standard error of the measurement was used to assess response stability of the ultrasound imaging technique. Results: No differences in the thicknesses of the transversus abdominis (TrA) muscle were measured during rest or while contracted, based on hand dominance (P Ն .73). Men had greater muscular thickness (P Ͻ .01), while the TrA in women represented a greater proportion of the total lateral abdominal muscles (P Ͻ .01). BMI was positively associated with muscle thickness (r Ն .66). Compared to a singular measurement, response stability improved by greater than 50% when an average of 3 measurements was used. Conclusions: Future researchers should assess the need to control for gender and BMI as potential covariates in ultrasound imaging studies of the lateral abdominal muscles. Asymmetry in the lateral abdominal muscles in those with LBP would be in direct contrast to the bilateral symmetry measured in those without LBP.

Secondary prevention involves monitoring and screening to prevent negative sequelae from chronic diseases such as cancer. Breast cancer treatment sequelae, such as lymphedema, may occur early or late and often negatively affect function. Secondary prevention through prospective physical therapy surveillance aids in early identification and treatment of breast cancer-related lymphedema (BCRL). Early intervention may reduce the need for intensive rehabilitation and may be cost saving. This perspective article compares a prospective surveillance model with a traditional model of impairment-based care and examines direct treatment costs associated with each program. Intervention and supply costs were estimated based on the Medicare 2009 physician fee schedule for 2 groups: (1) a prospective surveillance model group (PSM group) and (2) a traditional model group (TM group). The PSM group comprised all women with breast cancer who were receiving interval prospective surveillance, assuming that one third would develop early-stage BCRL. The prospective surveillance model includes the cost of screening all women plus the cost of intervention for early-stage BCRL. The TM group comprised women referred for BCRL treatment using a traditional model of referral based on late-stage lymphedema. The traditional model cost includes the direct cost of treating patients with advanced-stage lymphedema. The cost to manage early-stage BCRL per patient per year using a prospective surveillance model is $636.19. The cost to manage late-stage BCRL per patient per year using a traditional model is $3,124.92. The prospective surveillance model is emerging as the standard of care in breast cancer treatment and is a potential cost-saving mechanism for BCRL treatment. Further analysis of indirect costs and utility is necessary to assess cost-effectiveness. A shift in the paradigm of physical therapy toward a prospective surveillance model is warranted.

Purpose-To determine the extent and time course of upper limb impairment and dysfunction in women being treated for breast cancer, and followed prospectively, using a novel physical therapy surveillance model post-treatment.Patients and Methods-Subjects included adult women with newly diagnosed, untreated, unilateral, Stage I to III BC and normal physiological and biomechanical shoulder function. Subjects were excluded if they had a previous history of BC, or prior injury or surgery of the affected upper limb. Measurements included body weight, shoulder ranges of motion (ROM), manual muscle tests, pain levels, upper limb volume, and an upper limb disability questionnaire (ULDQ). Measurements were taken at baseline (pre surgery), and one, three-six, and 12 months post surgery. All subjects received pre-operative education and exercise instruction and specific physical therapy (PT) protocol after surgery including ROM and strengthening exercises.Results-All measures of function were significantly reduced one month post surgery, but most recovered to baseline levels by one year post surgery. Some subjects developed signs of lymphedema 3-12 months post surgery, but this did not compromise function. Shoulder abduction, flexion, and external rotation, but not internal rotation ROM, were associated with the ULDQ.Conclusion-Most women in this cohort undergoing surgery for BC who receive PT intervention may expect a return to baseline ROM and strength by three months. Those who do not reach baseline, often continue to improve and reach their pre-operative levels by one year post surgery. Lymphedema develops independently of shoulder function three to 12 months post surgery, necessitating continued monitoring. A prospective physical therapy model of surveillance allows for detection of early and later onset of impairment following surgery for BC in this specific cohort of patients.

Cancer-related fatigue is common, complex, and distressing. It affects 70–100% of patients receiving chemotherapy and a significant number who have completed their treatments. We assessed a number of variables in women newly diagnosed with primary breast cancer (BrCa) to determine whether biological and/or functional measures are likely to be associated with the development of clinically significant fatigue (CSF). Two hundred twenty-three women participated in a study designed to document the impact of the diagnosis and treatment of primary breast cancer on function. Forty-four had complete data on all variables of interest at the time of confirmed diagnosis but prior to treatment (baseline) and ≥9 months post-diagnosis. Objective measures and descriptive variables included history, physical examination, limb volume, hemoglobin, white blood cell count, and glucose. Patient-reported outcomes included a verbal numerical rating of fatigue (0–10, a score of ≥4 was CSF), five subscales of the SF-36, Physical Activity Survey, and Sleep Questionnaire. At baseline, the entire cohort (n = 223) and the subset (n = 44) were not significantly different for demographic, biological, and self-reported data, except for younger age (p = 0.03) and ER+ (p = 0.01). Forty-five percent had body mass index (BMI) ≥ 25, 52% were post-menopause, and 52% received modified radical mastectomy, 39% lumpectomy, 52% chemotherapy, 68% radiation, and 86% hormonal therapy. Number of patients with CSF increased from 1 at baseline to 11 at ≥9 months of follow-up. CSF at ≥9 months significantly correlated with BMI ≥ 25, abnormal white blood cell count, and increase in limb volume and inversely correlated with vigorous activity and physical function (p < 0.05). Fatigue increases significantly following the treatment of BrCa. Predictors of CSF include high BMI and WBC count, increase in limb volume, and low level of physical activity. These are remediable.

The objective of this study are (1) to determine if upper extremity function, as represented by shoulder ROM, self-reported symptoms and upper extremity functional limitations in activities of daily living could be predictively related to demographic and cancer characteristics post-surgery for breast cancer. And (2) to examine if variables related to early onset impairment contribute to late onset impairments in women after breast cancer surgery. Subjects were assessed preoperatively and 1, 3, 6, 9, and 12+ months post breast cancer surgery for impairments and symptoms and at 12+ months for shoulder functional limitations using a physical therapy surveillance model. Body weight, shoulder ROM, manual muscle testing, and upper limb volume were recorded. At 12+ months, the Harvard Alumni Health Study Physical Activity Questionnaire, and an Upper Limb Disability Questionnaire were administered. Symptoms and ROM impairments were compared by functional limitations. Characteristics significantly associated with early ROM impairment (but not later impairment) were axillary lymph node dissection, removal of ≥15 nodes, mastectomy surgery and stage II breast cancer. Positive nodes, older age, and BMI≥25 were significantly associated with reduced shoulder ROM at 12+ months. At 12+ months, only 10 % of the patients experienced ROM impairments while rates of self-reported symptoms in the affected upper extremity at 12+ months were as follows: pain-49%, weakness-47.1%, numbness-55.9%, feeling tired-42.5%. The majority of patients used the affected upper extremity for reaching without limitation, but ≥35% reported limitation with household chores, carrying and lifting. Difficulty carrying and lifting could be predicted by BMI≥25 and use of the dominant affected upper limb. Different factors are associated with early versus later ROM loss. Symptoms reported by breast cancer survivors are frequently associated with functional limitations in upper extremity tasks and warrant intervention. Physical therapy using a prospective surveillance model of care may reduce severity of ROM loss, symptoms and functional upper extremity limitations 1 year after breast cancer surgery.

Serial interval assessment of limb volume segments may be an important clinical tool to detect early-onset lymphedema before TLV changes.
