Brief summary: The aim of this study, determining the factors affecting the hand functions of children with Duchenne Muscular Dystrophy who have lost their independent ambulatory ability and determining the effects on the overall upper extremity performance and quality of life of the determined factors.

Detailed description: Duchenne Muscular Dystrophy (DMD) is the most common neuromuscular disease seen in childhood. DMD is an X linked recessive disorder. DMD is characterized by complete or partial (\<3%) deficiency of the cell membrane protein dystrophin.

Dystrophin deficiency results in a permanent deterioration of muscle fibers. This leads to a progressive decrease in muscle strength and functional abilities. The precise mechanism of how the defect of dystrophin leads to degeneration of muscle fibers remains uncertain, but cytoskeletal deterioration, sarcolemmal instability and abnormal calcium homeostasis are thought to play a role in this degeneration.

These patients have symptoms such as limb proximals and progressive muscle weakness in the trunk, gait abnormalities, Gower's sign, various degrees of restriction in daily living activities, and frequent falls. The majority of patients have elevated serum creatine kinase or elevated liver transaminases and less frequently language or general developmental retardation.

Walking ability of this children begins to deteriorate between the ages of 3-6. These patients are generally dependent on wheelchair aged 10-12 years. The loss of walking is the milestone in terms of the progression of the disease. The use of electric wheelchairs limits arm functions such as lengthening and lifting during the late phase of the illness (when the ambulance has been lost and the ambulance is being continued with the wheelchair).

Patients with DMD have an average life span of 30 years with spinal surgery and ventilation support. They spend most of their lives dependent on the wheelchair and need functional use of the upper limbs to maintain the best possible level of independence in their daily life activities throughout their lifetimes.

Although muscle weakness in the proximal limbs is the first finding of the disease, the influence of upper extremity functions gives symptoms after 8 years of age and has a great influence on the level of independence of DMD patients in life since this process. For this reason, rehabilitation approaches for the protection of upper extremity functions from the early period of the disease are of great importance.Effective interventions are necessary to achieve this goal and these variables must be considered when making clinical decisions.

Patients with adult DMD have been shown to be able to perform important functional activities with limited distal motor function in the late phase of disease, but tend to lose these capacities as muscle strength decreases. For this reason, determining the factors (grip strength, thumb opposition, upper extremity joint range of motion, upper extremity muscle strength, etc.) that may affect hand functions, which is an important component in maintaining upper extremity functioning, and how these factors are related to the general functions of the upper extremity it is crucial that this disease leads to physiotherapy rehabilitation programs to be implemented.
