performance ability, movement, muscle power, and motor ability. Among the intervention methods for trunk stabilization, a sling reduces the burden on the joints and simultaneously contracts the muscles restrained by pain, dynamically and statically, thereby stimulating the nerve roots and reactivating the muscles4). Recently, trunk stabilization exercise using a sling has been investigated in a number of studies,
Hemiplegia is the main symptom of stroke, which results in diverse sensory, motor, perception, recognition, and language problems1). Hemiplegia is commonly associated with a decrease in trunk adjustment ability. In particular, it causes a decrease in the activities of the lateral trunk muscles, and an increase in the asymmetry between the left and the right side, as well as paralysis of the trunk muscles. Additional complications are a decrease in the simultaneous contraction of the trunk muscles and a tendency to fall toward the paretic side, triggering problems, such as qualitative degradation of gait2). Physical therapy interventions are needed for these motor disorders to enable patients with brain damage to live independent lives. The trunk muscles are essential for the maintenance of different postures in daily life. Therefore, maintaining the strength and the endurance of the trunk muscles is crucial2). Core stability is a kinetic chain activity necessary for the stabilization of the trunk3). It regulates optimal task performance ability, movement, muscle power, and motor ability. Among the intervention methods for trunk stabilization, a sling reduces the burden on the joints and simultaneously contracts the muscles restrained by pain, dynamically and statically, thereby stimulating the nerve roots and reactivating the muscles4). Recently, trunk stabilization exercise using a sling has been investigated in a number of studies,
which have reported positive results. Balance and gait are impaired in hemiplegic patients due to loss or reduction of trunk adjustment ability. Therefore, selective trunk adjustment exercise is important, and trunk stabilization exercise is prescribed as an intervention
