Hematopoietic stem cell transplantation is a treatment used to restore blood cell function in diseases of myeloid and lymphoid origin, which can be malignant or non-malignant. There are two types: autologous transplantation, which uses the patient's own stem cells, and allogeneic transplantation, which uses stem cells from a donor after a high-dose chemotherapy and radiotherapy preparation. This process can lead to complications such as immune reactions, infections, and organ toxicity, affecting the cardiovascular, musculoskeletal, and nervous systems. These complications often reduce physical activity, muscle strength, lung function, and quality of life.
Before transplantation, it is important to assess patients' comorbidities, functional status, and physical fitness to evaluate their ability to tolerate treatment and risk of complications. Low exercise tolerance and impaired physical function are linked to poorer outcomes. Objective tests of physical function provide valuable information about health status. Pre-transplant muscle strength and cardiopulmonary fitness influence post-transplant recovery, so comprehensive assessments are necessary.
Physiotherapy and rehabilitation support patients by preparing them for treatment, maintaining health during therapy, improving physical function after treatment, and enhancing quality of life in palliative care. Exercise improves functional capacity, quality of life, and daily activities, but symptoms like fatigue, pain, breathlessness, and muscle weakness, as well as other barriers, may limit participation.
Physical fitness is the body's ability to perform daily activities efficiently. Reduced fitness leads to frailty and decreased function, which are associated with increased treatment toxicity and mortality. Although the importance of physical fitness before transplantation is recognized, data from objective measurements are limited. Common pre-transplant assessments include lung function tests, walking tests, handgrip strength, and mobility tests.
This study aims to compare the health-related physical fitness of individuals undergoing allogeneic hematopoietic stem cell transplantation with healthy controls.

| Physical Activity Level: | The level of physical activity will be assessed using the Turkish version of the short form of the International Physical Activity Questionnaire. This questionnaire was developed to measure health-related physical activity in populations and is both comprehensive and concise. It provides information on the time spent sitting, walking, and engaging in moderate and vigorous intensity physical activities. The total score is calculated by multiplying the duration and frequency of the physical activities reported. The energy expenditure associated with physical activities is expressed in metabolic equivalent-minute scores. Based on the scoring, the questionnaire categorizes individuals into three physical activity levels: inactive, moderately active, and active. The administration of the questionnaire can be conducted in two different formats: on paper or via a digital screen interface. | 4 weeks |

Functional exercise capacity will be evaluated using the Six-Minute Walk Test in accordance with the criteria of the American Thoracic Society and the European Respiratory Society. In this test, the individual is instructed to walk as fast as possible back and forth between two cones placed 30 meters apart in a straight corridor. Standardized encouragement phrases will be used throughout the test to motivate the participant. Vital signs will be assessed before and after the test, as well as during the recovery period. The total distance walked during the six-minute period will be recorded in meters, and the average walking speed will be calculated in meters per minute. |

| Postural Assessment: | The Posture Analysis Form developed by Corbin will be used for the assessment of postural alignment. The evaluation will be conducted through visual observation from both lateral and posterior views. The presence and severity of postural deviations will be assessed. Each item in the form is scored based on the severity of the deviation as follows: 0 = none, 1 = mild, 2 = moderate, 3 = severe. The total score will be used to classify the individual's overall postural status. | 4 weeks |
| Sit and Reach Test | Sit and Reach Test reflects lower body flexibility. In this test, the patient will be seated in front of a box with dimensions of 35 cm length, 45 cm width, 32 cm height, and after leaning his bare feet on the inner surface of the box, patient will try to move the bar on the plate as far as patient can with both hands, the value at the last point will be recorded in cm. | 4 weeks |
| Assessment of Respiratory Muscle Strength | Respiratory muscle strength will be evaluated by measuring maximum inspiratory mouth pressure and maximum expiratory mouth pressure using a portable electronic mouth pressure measurement device. Results will be recorded in cmH₂O. Maximum inspiratory mouth pressure is defined as the pressure generated in the mouth during maximal inspiration against an occluded airway. For this measurement, participants will first perform a maximal expiration, after which the airway will be closed with a valve, and the participant will be asked to perform a maximal inspiration sustained for 1-3 seconds. maximum expiratory mouth pressure refers to the pressure generated in the mouth during maximal expiration against a closed airway. For maximum expiratory mouth pressure measurement, after a maximal inspiration, the participant will be instructed to exhale maximally against the occluded airway for 1-3 seconds. | 4 weeks |
