El presente estudio tiene como objetivo evaluar la funcionalidad de miembro superior, síntomas de fatiga y nivel de actividad física en mujeres post operatorio de cáncer de mama, grupo PO, en comparación a un grupo control de mujeres sanas. La funcionalidad de la extremidad superior se evaluó mediante el rango de movimiento (ROM) de flexión, abducción y rotación externa del hombro utilizando un inclinómetro digital; fuerza de prensión con un dinamómetro y discapacidad del miembro superior con el cuestionario Disabilities of the arm, shoulder and hand. La fatiga se evaluó con el Inventario Breve de Fatiga y el nivel de actividad física con el Cuestionario Internacional de Actividad Física. Treinta y cuatro mujeres (n=17, grupo PO; n=17, grupo control, GC) fueron evaluadas. El grupo PO presentó menor ROM del hombro y fuerza de prensión (diferencia de rango: 22,9°-22,9°; 5,6kgF, respectivamente) en comparación con el GC; el lado afectado presentó menor ROM del hombro en comparación con el lado no afectado (15°-21°). También hubo una mayor discapacidad en el lado afectado y un menor nivel de actividad física en el grupo PO. No hubo diferencias en la fatiga entre los grupos. Concluimos que el grupo PO presentó menor funcionalidad y un bajo nivel de actividad física en comparación con un grupo control. Abstract. This study aim to compare upper limb functionality, fatigue and physical activity level in women after breast cancer surgery in relation to a control group. Upper limb functionality was evaluated by mean of shoulder range of motion (ROM) of flexion, abduction and external rotation using a digital inclinometer; handgrip strength using a dynamometer and upper limb disability with the Disabilities of the arm, shoulder and hand questionnaire. Fatigue was assessed with the Brief Fatigue Inventory and physical activity level with the International Physical Activity Questionnaire. A thirty-four women (n=17, post-operated breast surgery group, PO; n=17, control group, CG) were recruited. PO group presented a decrease in both shoulder ROM and handgrip strength (range difference: 22.9°-22,9°; 5.6kgF, respectively) compared to CG; the affected side of the PO group presented with less shoulder ROM in comparison to the non-affected side (15°-21°). There was also greater disability on the affected side and a lower physical activity level in the PO group. There were no differences in the fatigue between the groups. We concluded that PO group presented with compromised functionality and low physical activity level compared to a control group.

Background. With treatment for breast cancer, women treated may present significant sensory abnormalities in the upper extremity. However, there are no conclusive studies that have evaluated pressure pain thresholds (PPT) in the shoulder of postoperated women for breast cancer. The aim of this study was to compare PPT in the shoulder, stress, anxiety, depression symptoms, and quality of sleep among postoperated women for breast cancer (PO group) and asymptomatic women of shoulder pain (control group). Methods. 40 women participated ( n = 20 , PO group, age: average ± standard   deviation , 49.2 ± 8.3 years; body mass index (BMI): 27.5 ± 3.0  kg/cm2; surgery time: 22.2 ± 34.4 months; n = 20 , control group, 46.9 ± 8.1 years; BMI: 26.8 ± 3.5  kg/cm2). The PPT was evaluated with a digital algometer at 32 points in the shoulder region and one control point in the tibialis anterior. Stress, anxiety, and depression were evaluated with the Depression, Anxiety and Stress Scale 21 (DASS-21) and the quality of sleep by the Pittsburgh Sleep Quality Index. Results. Significant differences were observed over 1.5 kgf/cm2 in 33 points evaluated ( p < 0.01 ) with a small to high effect size (Cliff’s delta range = 0.16 ; 0.92) and higher levels of anxiety and stress in the PO group (anxiety: median [first; third quartile], 5[3; 12.5]; stress: 9.7 ± 4.7 (7.8; 11.8)) in comparison with the control group (anxiety: 2.5[1; 4.8]; stress: 6.7 ± 3.31 (5.2; 8.3), ( p < 0.05 )). No significant differences were found between the groups in depression and sleep quality ( p > 0.05 ). Conclusion. Postoperated women for breast cancer present hyperalgesia in the shoulder anterior and posterior region, low PPT in the tibialis anterior, and higher levels of stress and anxiety compared to the control group.

El objetivo de este estudio fue comparar la predicción del V̇O2máx. entre mujeres sobrevivientes de cáncer de mama y un grupo control (GC) de mujeres sin antecedentes de cáncer. Estudio de caso-control en que diecisiete mujeres en el grupo sobrevivientes de cáncer de mama (49.4 ± 8.9 años, índice de masa corporal [IMC] de 27.8 ± 2.7 kg·m-2) y 17 en el GC (47.9 ± 7.4 años, IMC de 26.2 ± 4.4 kg·m-2) fueron evaluadas. La prueba de caminata de seis minutos (PC6M) se evaluó con monitor de frecuencia cardíaca, tensiómetro digital, oxímetro de pulso y escala de Borg. El V̇O2máx. se estimó con ecuación que consideró la distancia recorrida, el peso corporal y la edad. El grupo de sobrevivientes caminó 34.8 metros más que el GC (p = .15; d = .51). También mostró una tendencia (p = .05), con un tamaño del efecto moderado (d = .76), hacia un aumento del V̇O2máx. (1.74 ± .26 L·min-1) comparado con el GC (1.56 ± .21 L·min-1). No hubo diferencias entre los grupos para las variables de frecuencia cardíaca, presión arterial y esfuerzo percibido durante la prueba (p > .05). Las participantes que recorrieron más distancia tuvieron más probabilidades de un mayor V̇O2máx. (odds ratio = 12.7; p = .002). Existieron diferencias en el V̇O2máx. entre los dos grupos, esta aptitud física debería considerarse para el tratamiento y control post-operatorio. Abstract. The aim of the study was to compare the prediction of the V̇O2max in breast cancer survivors and a control group (CG) of women without a history of cancer. It is a case-control study. Seventeen women in the breast cancer survivors (49.4 ± 8.9 years, body mass index [BMI] of 27.8 ± 2.7 kg·m-2) and 17 in the CG (47.9 ± 7.4 years, BMI of 26.2 ± 4.4 kg·m-2) were evaluated. The six-minute walk test (SMWT) was evaluated with a heart rate monitor, digital blood pressure monitor, pulse oximeter and the Borg scale. The V̇O2max it was estimated with an equation that considered the distance traveled, body weight and age. The survivors group walked 34.8 meters more than the CG (p = .15). In addition, group showed a trend (p = .05), with a moderate effect size (d = .76), towards an increase in V̇O2max (1.74 ± .26 L·min-1) compared to the CG (1.56 ± .21 L·min-1). There were no differences between the groups for the variables of heart rate, blood pressure and perceived exertion during the test (p > .05). The participants who covered the longest distance had a better chance of a V̇O2max higher (odds ratio = 12.7; p = .002). There were differences in the V̇O2max between groups, this physical fitness should be considered for post-operated treatment and monitoring.
