상세 설명

Breast cancer is one of the most common neoplasms and a leading cause of death among women worldwide, representing a significant public health problem. Beyond the physiological impact of the disease, cancer treatment, which may include surgery, chemotherapy, radiotherapy, immunotherapy, and hormone therapy, is associated with various adverse physical and emotional effects. Among the main impairments observed are pain, fatigue, loss of muscle strength, reduced flexibility, functional limitations of the upper limbs, changes in body composition, anxiety, depression, and significant impairments in quality of life. These effects can directly compromise the functional autonomy, self-esteem, and overall well-being of patients during and after treatment. In this context, physical exercise has been widely recommended as a complementary non-pharmacological strategy to minimize the side effects of breast cancer treatment. Among the exercise modalities, the Pilates Studio method stands out for integrating muscle strengthening, respiratory control, flexibility, balance, and body awareness, promoting physical and psychosocial benefits. Furthermore, Pilates allows for individualized adaptation of exercises, enabling women undergoing cancer treatment to perform activities safely and progressively according to their functional limitations. Studies demonstrate that interventions based on the Pilates method can contribute to improved quality of life, functionality, muscle strength, range of motion, and reduced fatigue in women with breast cancer. However, most research focuses on mat Pilates, with a scarcity of studies specifically addressing the effects of Studio Pilates, performed with specific equipment and progressive load control. Therefore, this study aims to evaluate the effects of a Studio Pilates program on quality of life, functional capacity, pain, fatigue, sarcopenia, muscle strength, flexibility, body composition, self-esteem, anxiety, and depression in women undergoing breast cancer treatment. It is expected that the results will contribute to expanding the scientific evidence on the use of Studio Pilates as a complementary therapeutic tool in cancer care, promoting the physical, functional, and emotional rehabilitation of this population.

기간
Pain assessment
기간: From registration to the end of treatment in 16 weeks
Pain will be assessed using the Brief Pain Inventory (BPI), a 10-point pain intensity scale ranging from 0 (no pain) to 10 (worst imaginable pain), developed specifically for patients with cancer-related pain. In addition, the BPI provides information on how pain interferes with daily functioning in 7 areas: general activity, walking, mood, sleep, work, enjoyment of life, and social activity.
From registration to the end of treatment in 16 weeks
Fatigue
기간: From registration to the end of treatment in 16 weeks
Fatigue will be measured using the Piper Fatigue Scale (PFS-P). Fatigue is a relevant symptom for cancer patients, with a greater impact than in the general population. It is described at all stages of the cancer patient's journey, presenting as physical, emotional, or cognitive exhaustion or weakness, which can interfere with daily function and chemotherapy treatment.

Sarcopenia
기간: From registration to the end of treatment in 16 weeks
Sarcopenia assessment will be performed using the SARC-F questionnaire. The protocol includes five components: strength, assisted gait, rising from a chair, climbing stairs, and falls. The SARC-F items were selected to reflect changes in health status associated with the consequences of sarcopenia. SARC-F scale scores range from 0 to 10 (i.e., 0-2 points for each component; 0 = best to 10 = worst) and were dichotomized to represent symptomatic (4+) versus healthy (0-3) status. Additionally, a modified version of the instrument, the SARC-Calf (SARC-F + CP), which integrates an anthropometric measure into the traditional score, was employed.

Functional capacity of upper limbs
기간: From registration to the end of treatment in 16 weeks
The Back Scratch Test is part of the battery of physical fitness tests for older adults and is used to measure the flexibility and range of motion of the shoulder joint (scapular girdle). The test consists of placing one hand on the same shoulder and the other hand underneath, attempting to touch or overlap the middle fingers of both hands on the back. The distance between the fingers is measured, where positive values indicate overlap and negative values indicate the distance remaining for touch. Test scores are classified as: negative (-): If the fingers do not touch (distance between them); zero (0): If the fingers only touch; positive (+): If the fingers overlap.

Functional capacity of the upper limbs
기간: From registration to the end of treatment in 16 weeks

The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire is a validated self-administered instrument for assessing symptoms and functional capacity in individuals with musculoskeletal disorders of the upper limbs.

The questionnaire is validated for Brazilian Portuguese and consists of 30 items that assess an individual's ability to perform certain physical activities (21 items), the severity of symptoms such as pain, tingling, and weakness (5 items), and the impact of upper limb function on social life, work, sleep, and self-confidence (4 items). Each item is scored on a scale of 1 to 5. DASH score = ({Sum of responses}/{n} - 1 ) x 25. Where n is the number of questions answered. The score ranges from 0 to 100, where the higher the value, the greater the functional disability.

General Flexibility
기간: From registration to the end of treatment, in 16 weeks
For flexibility assessment, the Schober test was used, which determines functional flexibility and is more specific to the lumbar region. It is a test with high specificity compared to the gold standard, radiography. However, it is a quick and low-cost test, widely used in clinical practice. The test evaluates lumbar movement restrictions through markings: on the lumbosacral joint (joining the posterior superior iliac spines) and 10 cm above; the distance between these markings is noted in an upright position. Immediately after, the subject performs a maximum trunk flexion (lower limbs extended), and the evaluator measures the new distance between the points with a measuring tape and records the difference between the marks based on the patient's best reach score in relation to the ground.

Upper limb strength
기간: From registration to the end of treatment, in 16 weeks
Measuring handgrip strength using a dynamometer is a simple, objective, practical, and easy-to-use procedure. Recommended by the American Society of Hand Therapists. The instruction is to perform a maximum contraction for 3 seconds in each test. A 30-second rest period is required between each test, and a 2-minute rest period is required between tests for each hand.

Lower limb strength
기간: From registration to the end of treatment, in 16 weeks
The 30-Second Chair Stand Test is widely used to assess lower limb strength and muscle endurance in clinical and elderly populations. The protocol requires the participant to stand from a chair and sit down as many times as possible within 30 seconds, without using their hands. Performance on this test is a strong predictor of functional autonomy and is directly related to screening for sarcopenia risk. Classification varies according to age and conditioning achieved during the test, defined as: Disability Risk: >8 repetitions for women are considered predictors of high risk of falls and loss of autonomy; Cutoff Point for Sarcopenia: >15 repetitions is an indicator of reduced muscle quality.
