Correlation Between the Trajectory of the Center of Pressure and Thermography of Cancer Patients Undergoing Chemotherapy.

OBJECTIVE: The purpose of this study was to correlate potential the stabilometric parameters of baropodometry with the superficial temperature of the legs of cancer patients during and after treatment. METHODS: This study included 30 volunteers of both sexes, divided into the following groups: chemotherapy-radiotherapy group (n = 15; age = 57.13 ± 16.74 years) and cancer group without current treatment (n = 15; age = 63.29 ± 7.34 years). They were assessed for superficial temperature of the legs using infrared thermography with anterior and posterior views. Assessment of postural balance was conducted using a baropodometer, in 2 conditions-participants' open and closed eyes-to obtain the center of pressure (COP) of anteroposterior displacement, center of pressure of mediolateral displacement (COP-ML), and center of pressure of displacement area. RESULTS: When their eyes were open, the chemotherapy-radiotherapy group presented a high correlation between the displacement of the ML and the surface anterior temperature of both legs (right: r = 0.578; P = .030; left: r = 0.619; P = .018) and posterior region of the right leg (r = 0.571; P = .033), and they presented a high correlation between COP with anterior surface temperature of both legs (right: r = 0.585; P = .028; left: r = 0.540; P = .046). When patients' eyes were closed, no correlation was found between the thermography and the stabilometric parameters evaluated. CONCLUSION: During the chemotherapy-radiotherapy, cancer patients present ML and COP displacement that correlates with infrared thermography evaluation when their eyes are open.

Análise intra e interavaliadores da projeção do centro de massa do corpo obtido por fotogrametria / Análisis intra e interevaluadores de la proyección del centro de masa del cuerpo obtenido por fotogrametría / Intra and inter-rater reliability of the projection of the body's center of mass obtained via photogrammetry

RESUMO Para o ótimo controle postural, o centro de massa (COM) do corpo é uma variável que se projeta verticalmente entre os pés, dentro de uma base de suporte. Este estudo teve por objetivo avaliar a confiabilidade inter e intra-avaliadores da projeção do COM na base de sustentação, mensurada com auxílio do Software de Avaliação Postural (SAPO). Cinquenta e sete voluntárias foram avaliadas e todas foram submetidas ao registro fotográfico nas vistas anterior, lateral direita e esquerda, no mesmo instante temporal. As imagens foram entregues a dois examinadores, os quais utilizaram o SAPO. Para a análise estatística, foi utilizado o coeficiente de correlação intraclasse (ICC) e, para estimar a mínima mudança detectável (MMD), foi utilizado o erro padrão (EP). Os resultados demonstraram excelentes níveis de confiabilidade interexaminador e intraexaminador para assimetrias nos planos frontal, sagital e para a projeção do centro de gravidade no plano frontal e lateral (ICC>0,90; 95%IC>0,95; MDD entre 2,16 - 4,87). Os resultados do estudo demonstraram que a análise do COM obtida por meio do SAPO apresentou boa confiabilidade nas análises inter e intra-avaliadores.

Este estudio tuvo por objetivo evaluar la confiabilidad inter e intraevaluadores de la proyección del COM en la base de sostenimiento, medida con apoyo del Software de Evaluación Postural (SAPO). Se evaluaron cincuenta y siete voluntarias y todas han sido sometidas al registro fotográfico en las vistas anterior, lateral derecha e izquierda, en el mismo instante temporal. Las imágenes han sido entregadas a dos examinadores, que utilizaron SAPO. Para el análisis estadístico, se utilizó el coeficiente de correlación intraclase (ICC) y, para estimar el mínimo cambio detectable (MMD), se utilizó el error estándar (EP). Los resultados demostraron excelentes niveles de confiabilidad interexaminador e intraexaminador para asimetrías en los planos frontal y sagital y para la proyección del centro de gravedad en el plano frontal y lateral (ICC>0.90, 95% IC>0.95, MDD entre 2.16 - 4.87). Los resultados del estudio demostraron que el análisis del COM obtenido a través de SAPO presentó buena confiabilidad en los análisis inter e intraevaluadores.

ABSTRACT For optimal postural control, the center of mass (COM) of the body is a variable that is projected vertically between the legs, over a support base. This study had as aim assessing the inter- and intra-rater reliability of the projection of the COM over the support base, measured with the aid of the Postural Evaluation Software (SAPO). Fifty-seven volunteers were evaluated and all were subjected to photographic records taken from the anterior, left and right lateral views, at the same time. The pictures were handed over to two raters, who then used SAPO to analyze them. For the statistical analysis, the intra-class correlation coefficient (ICC) was used, and to estimate the minimum detectable change (MDC), the standard error (SE) was used. The results showed excellent levels of inter and intra-rater reliability for asymmetries in the frontal and sagittal planes, and for the projection of the center of gravity in the frontal and lateral planes (ICC>0.90; 95%CI>0.95; MDC between 2.16 - 4.87). The results of the study showed that the analysis of the COM obtained with SAPO had good inter- and intra-rater reliability.

Influence of Exergaming on the Perception of Cancer-Related Fatigue.

OBJECTIVE: Exercise is recommended for cancer patients to reduce fatigue and improve quality of life. This study's aim is to evaluate the influence of an exergaming protocol on cancer-related fatigue, muscle fatigue, and muscle strength in cancer patients. MATERIALS AND METHODS: We conducted a quasi-experimental control study using exergaming in all groups through an Xbox360 Kinect™ console, two to three times per week, for 20 sessions. Three groups were created: cancer patients in chemotherapy and/or radiotherapy group (CRG; n:15), cancer patients after chemotherapy and/or radiotherapy (CAG; n:15), and a control group (CG; n:15). They were assessed for cancer-related fatigue using the fatigue subscale of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire. To assess dorsiflexor and plantar flexor muscle functioning, we used median frequency (MDF) of the surface electromyography and muscle strength using a dynamometer. The assessments were performed preintervention (EV0), after 10 sessions (EV1), and after 20 sessions (EV2). RESULTS: With an exergaming protocol, CRG and CAG showed a reduction in related fatigue compared with CG (P < 0.01). The CRG group saw an increase in maximal voluntary isometric contraction in right plantar flexor muscles and dorsiflexor muscles, as well as an increase in the MDF of both medial gastrocnemius muscles and the left tibialis anterior muscle of the CAG. For other analyses done, the differences were observed during exergaming. CONCLUSIONS: Exergaming demonstrated efficacy in reducing cancer patients' fatigue, including muscle fatigue, and increasing muscle strength in patients' legs.
