Effect of trunk stabilization exercise on gait

The ability of the trunk muscles to be activated before voluntary movements of the extremities occurs and to maintain the stability of the body is called proactive posture control, which minimizes unnecessary body movements and provides stability to the proximal part to ensure smooth movement of the distal part. provoke

However, the muscle weakness of the trunk muscles due to stroke increases the instability of the body due to the delay in the occurrence time of the proactive postural control, and as a result, the trunk performance is lowered. This leads to a decrease in the patient's quality of life.

For stroke patients, the control ability and muscle strength of the trunk muscles involved in lower trunk stability are very important in improving posture control, and strengthening exercises for trunk muscles for trunk stabilization are very effective in improving posture control.

The improvement of the balance ability enables selective movement of the trunk and body segments, and increases the contractile force of the extensor so that the body can be well maintained in the anti-gravity direction, thereby improving balance and walking ability.

Balance ability for proper body weight transfer during walking and ideal posture alignment between body segments are required.

In trunk stabilization, active stability is created by the cooperative contraction of the trunk and muscles around the pelvis, which automatically responds to unexpected fluctuations in the body during various functional movements, including walking, to maintain balance and to perform effective walking. let it be However, due to stroke, trunk muscle weakness and sensory deficits delay the onset of the automatically occurring balance response, affecting balance and walking ability.

Human gait refers to the ability to move the body from one place to another while maintaining balance through the adjustment of the corresponding muscles as an integrated process of the central and peripheral nervous systems. By generating and potential energy, it is possible to maintain a minimum physiological gait energy consumption, thereby enabling efficient walking.
