Introduction: Fanconi anemia (FA) is a rare autosomal recessive DNA repair disorder characterized by congenital malformations, progressive bone marrow failure, and reduced quality of life. Although physical and occupational therapy are routinely recommended to address skeletal anomalies in FA, no studies have evaluated the impact of a structured corrective exercise and rehabilitation program on patient outcomes.
Method: In this single case clinical report, an adult FA patient will complete a 12 week supervised corrective exercise and rehabilitation program (36 sessions; 3 × 40-45 min/week) delivered via in-person supervised sessions. Primary outcome is change in patient reported quality of life (SF 36) from baseline to week 12; secondary outcomes include muscle strength, fatigue severity, postural parameters, and hematological indices.
Fanconi anemia (FA), first described in 1927 by Dr. Guido Fanconi, is a rare, inherited, autosomal recessive disorder affecting proteins involved in DNA repair and cell cycle regulation. This syndrome is characterized by congenital malformations (involving the limbs, skeletal system, kidneys and urinary structures, sensory organs (eyes and ears) and central nervous system), progressive bone marrow failure (aplastic anemia), increased cancer incidence (particularly head/neck epithelial cancers and acute myeloid leukemia (AML)) and a range of physical anomalies (including microcephaly and short stature).
Higher prevalence rates of FA have been observed in populations with a high incidence of consanguineous marriages, including South African Blacks, Turks, Saudi Arabians, Ashkenazi Jews and Iranians. Globally, the disorder affects approximately 1 in every 160,000 to 360,000 individuals, while the estimated carrier frequency is around 0.3%.
FA results from mutations in at least 22 genes involved in genomic stability and DNA repair. The majority of FA-related changes-accounting for more than 80%-are found in the FANCA, FANCG, and FANCC genes, whereas alterations in the remaining genes are comparatively rare.
The diagnosis of FA, though challenging due to variable expressiveness, relies on clinical suspicion confirmed through genetic analysis. FA should be suspected in cases of de novo bone marrow failure, especially in younger patients, or in the presence of spontaneous chromosomal breaks and certain cytogenetic abnormalities. Early diagnosis, while not currently improving cure rates, enables healthcare professionals to implement systematic follow-up protocols and timely interventions.
Therapeutic management of FA relies on vigilant, risk adapted monitoring of hematologic status-complete blood counts and bone marrow assessments are scheduled from every six months to six weeks based on cytopenia severity-to detect dysplasia or clonal abnormalities. Supportive care with red cell and platelet transfusions, infection prophylaxis, and occasional androgen therapy helps maintain blood counts while preparing for hematopoietic stem cell transplantation (HSCT). Transplantation, preferably before transfusion dependence or emergence of poor risk cytogenetic changes, offers the only curative approach to marrow failure. Simultaneously, long term surveillance addresses FA's systemic complications through regular cancer screenings and organ specific evaluations.
Despite the established role of physical and occupational therapy in managing skeletal abnormalities in FA, there is a notable scarcity of research specifically examining the effectiveness of structured exercise rehabilitation programs for this population. In a similar study, Ye et al. (2024) found that a structured exercise rehabilitation program improved quality of life, reduced fatigue, and enhanced physical performance in aplastic anemia patients undergoing HSCT. These promising outcomes support the potential benefit of a similar approach in Fanconi anemia patients. Based on the identified research gaps, the investigators hypothesize that a structured program of corrective exercise, physical therapy interventions, and rehabilitation will improve quality of life, physical function, and potentially influence hematological parameters in patients with Fanconi anemia.
The primary objective of this case study is to evaluate the effectiveness of these interventions on patient-reported quality of life. Secondary objectives include assessing improvements in muscle strength, fatigue levels, functional independence in activities of daily living, and monitoring potential changes in hematological indicators. Our intervention will encompass a structured exercise rehabilitation program beginning at an appropriate phase of treatment and continuing through a defined follow-up period. This case study aims to provide preliminary evidence to guide the development of comprehensive rehabilitation protocols specifically designed for the FA population, addressing both the skeletal abnormalities and the systemic manifestations of the condition.

| Corrective exercise and rehabilitation | Behavioral | This is a longitudinal single-subject case study in which one adult patient diagnosed with Fanconi anemia will undergo a structured, supervised corrective exercise and rehabilitation program. The subject will serve as their own control, with baseline measurements compared to post-intervention outcomes. |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of changes in hyper-kyphosis | Evaluating the effect of supervised exercise on hyper-kyphosis using the Debrunner Kyphometer, a non-radiologic gold standard tool. This device measures the kyphosis angle by positioning its arms on the spinous processes of T2-T3 (upper point) and T11-T12 (lower point), with direct angle readings from the calibrated scale. Measurements are taken in degrees, with hyper-kyphosis defined as ≥53° in women and ≥55° in men. | Pre-intervention and Week 12 |
| Rate of changes in forward head posture | Evaluating the effect of supervised exercise on forward head posture craniocervical angle (CVA) analysis using digital photogrammetry. Reflective markers are placed on the C7 spinous process and the tragus of the ear, followed by lateral image capture at a standardized 1.5-meter distance. Image analysis software, such as Kinovea, automatically calculates the CVA angle. A normal posture is defined as CVA ≥53°, while a severe forward head posture is <50°. | Pre-intervention and Week 12 |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Quality of Life (SF-36) | Evaluating improvements in quality of life using the Kidney Disease Quality of Life 36-item survey (KDQOL-36) questionnaire. For all KDQOL-36 subscales, scores range from 0 to 100, with higher scores consistently indicating better health-related quality of life outcomes. | Pre-intervention and Week 12 |

| Change in Fatigue Severity |
Measuring fatigue levels before and after the intervention using Fatigue Severity Scale (FSS) (9 items on a Likert scale 1-7 (total range 9-63); Score interpretation: ≥36 indicates clinical fatigue, ≤18 indicates no fatigue. ICC = 0.91). Higher scores indicate greater fatigue. |
| Pre-intervention and Week 12 |
| Rate of changes of daily physical activity level | Assessing the effect of supervised exercise on daily activity levels using the LowPAQ questionnaire which evaluates physical activity across occupational, transportation, household, leisure, and sedentary domains, with scoring in MET-minutes per week for light (3.3 MET), moderate (4.0 MET), and vigorous (8.0 MET) activities. Activity levels are categorized as low (<600 MET-min/week), active (600-3000 MET-min/week), and highly active (>3000 MET-min/week), aligned with WHO guidelines. | Pre-intervention and Week 12 |
| Change in Muscle Strength | To evaluate the impact of the intervention on muscle strength using handheld dynamometry. Handheld dynamometry is a quantitative method for measuring isometric muscle strength. The device records maximal force exerted by the patient in standardized positions. It is portable and has shown high intra- and inter-rater reliability. The full assessment typically takes 15-20 minutes and includes major muscle groups involved in posture and mobility. | Pre-intervention and Week 12 |
| Rate of changes of balance and fall risk | Assessing balance improvements and fall risk reduction using Timed Up and Go (TUG) Test duration (unit: seconds, Time required to rise, walk 3 meters, turn, and return; diagnostic threshold ≥12 seconds indicates fall risk). | Pre-intervention and Week 12 |
| Rate of changes of physical function | Evaluating physical function improvement using the 6-minute walk test (6MWT), which measures the maximum distance covered in 6 minutes (unit: meters). Reference values: 400-700 meters for older adults and 150-346 meters for heart failure patients. | Pre-intervention and Week 12 |
| Number of participants with abnormal hematological test results | Abnormal values will be defined based on standard lab reference ranges for Hgb, WBC, and Plt. Outcome reported as number of participants with ≥1 abnormal value. | Baseline, Week 6, and Week 12 |
