The Relationship of Trunk Control With Lower Extremity Sense, Balance and Gait in Stroke
The Relationship of Trunk Control With Lower Extremity Sense, Balance and Gait in Stroke
Cerebrovascular accident is the third leading cause of death in developed countries after heart disease and cancer. In adults, it ranks first among neurological diseases in terms of causing death and disability. About one-third of stroke patients experience permanent physical dysfunction. This situation has a negative impact on the economic, social, psychological life and general quality of life of the patient and his family. Stroke is one of the leading causes of long-term disability in adults due to problems such as activity limitations and participation restrictions caused by disorders in body functions. Movement disorder is one of the most common symptoms of stroke, and people with stroke often have trouble falling while walking after they are discharged from the hospital. Therefore, one of the main goals of stroke rehabilitation is to regain independent mobility with a safe and stable gait pattern. In addition to all these, one of the problems faced by most stroke patients is sensory-perception disorders. Sensory impairment can be experienced as the inability to perceive the senses or the inability to distinguish the senses. It should be considered that sensory awareness decreases as more than one sensory impulse competes with each other at the same time, and this situation should not be ignored during the evaluation. Although motor movement is governed by the normal motor field, the adjustment of our position in space is entirely the task of the sensory field. It is not possible to initiate and coordinate movement without sensory control. Since environmental change cannot be perceived during movement, it is not possible to provide environmental adaptation.
When the literature is examined, it is stated that the best functional results are revealed by a good postural control. Because the trunk is the key point of the body. Proximal trunk control is essential for distal extremity movements, balance and functional activities. It provides trunk control, static and dynamic posture, upright posture of the body, and selective trunk movements. Studies have emphasized the importance of intensive rehabilitation therapy targeting trunk control after stroke. Several randomized controlled trials have looked at the effects of trunk exercises in people with stroke. Saeys and colleagues have shown that the effects of trunk exercises improve standing balance and mobility as well as trunk performance.
There are only a few clinical assessment tools in the literature to evaluate trunk performance. The Trunk Disorder Scale examines static and dynamic sitting balance and trunk coordination. "Postural Assessment Scale for Stroke Patients" (PASS) was developed to evaluate postural control and balance in detail in stroke patients. This scale helps to evaluate postural control and balance of stroke patients, to predict prognosis, to shape treatment, and to observe time-dependent development.
In the literature, the rate of sensory problems accompanying stroke is given differently. In the study conducted by Kim and Choi-Kwon in 67 individuals with acute stroke, two-point discrimination, localization identification, position sense, and stereognosis senses were evaluated and it was found that these senses were affected in 85% of the individuals. In another study, it was stated that sensory impairment in the lower extremities affected gait speed, gait symmetry, standing and walking balance.
However, the relationship between trunk control and lower extremity sense of stroke individuals has not been examined in the literature. In addition, studies on balance and walking have not been sufficiently observed.
