Studies have shown that these patients have muscle weakness and delayed activity of trunk muscles, significant loss of trunk position sense, insufficient pressure control center while sitting, decreased trunk performance, and trunk asymmetry during walking. It has been reported that trunk function with balance and walking ability in stroke patients is a useful determinant of daily life activities, balance and walking ability. Balance disorders may be the result of changes in the sensory and integrative aspects of motor control. In the subacute phase, more than 80% of the subjects who have had stroke for the first time have an imbalance in their balance. After a stroke, upper motor neuron damage can cause unconditioned. This results in physical inactivity and decreased cardiorespiratory fitness. Respiratory muscle weakness and changes in thoraco-abdominal motion may be associated with a decrease in tidal volume and lower exercise tolerance.
Stroke is often associated with secondary complications such as nutritional and metabolic disorders, endocrine dysfunction, mental problems, and cardiopulmonary disorders caused by neurological and musculoskeletal deficits. The absence of the paretic side muscles and the difficulty of movement together with restrictive pulmonary disorders trigger a secondary decrease in cardiopulmonary function and expose insufficient energy associated with gait resulting in a decrease in asymmetric trunk exercise endurance.
