Effects of a Pilates Studio Program on Quality of Life, Functional Capacity, Pain, Fatigue, Sarcopenia, Flexibility, Strength, Body Composition, Self-Esteem, Anxiety and Depression in Women Undergoing Breast Cancer Treatment
Introduction: Cancer treatment generates undesirable effects, directly affecting the functional and psychosocial capacity faced by breast cancer patients during treatment.
In order to evaluate the practical effects of a pilates studio program that aims to promote significant improvements in their quality of life, emotional and social well-being.
Objective: To assess quality of life, pain, fatigue, sarcopenia, flexibility of upper limbs, functional capacity, functional independence, general flexibility, strength of upper limbs and lower limbs, muscle mass, self-steem, anxiety and depression in women undergoing breast cancer treatment.
Method: This is a cross-sectional study in which the sample will be composed of female individuals undergoing cancer treatment who participated in a Pilates studio program, twice a week lasting 60 minutes with light to moderate exercises, the intervention will last 16 weeks.
The primary outcomes of study will be quality of life, pain, fatigue, sarcopenia, flexibility of upper limbs, functional capacity, functional independence.
The secondary outcomes of study will be general flexibility, strength of upper limbs and lower limbs, muscle mass, self-steem, anxiety and depression in women undergoing breast cancer treatment.
All evaluated using instruments: EORTC-QLQ-30 and EORTC-QLQ-23 questionnaires (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire); Brief Pain Inventory; PIPER Fatigue Scale; SARC -F and SARC-Calf questionnaires; Back Scratch Test; Disabilities of the Arm, Shoulder and Hand Questionnaire - DASH; Six-minute walk test (6MWT) and 6-Minute Step Test; Barthel Index; Schober test; Handgrip Strength and 30-second sit-to-stand test; Bioimpedance; Rosenberg Self-Esteem Scale and Hospital Anxiety and Depression Scale (HADS), respectively.
The data will be presented by descriptive statistics, for two independent samples and multivariate analysis, comparing the effects of the intervention between the two groups in the R 4.3.3
software.
Expected results: Improvement in primary and secondary outcomes due to adjustments in physical training, Pilates studio.
調査の概要
詳細な説明
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.

Functional capacity of upper limbs
時間枠：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.

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. |

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.

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.
