Repetitive sit-to-stand training with the step-foot position on the non-paretic side, and its effects on the balance and foot pressure of chronic stroke subjects

Abstract

[Purpose] This study aimed to improve the asymmetrical weight-bearing ratio by applying repetitive sit-to-stand training methods that feature a step-foot position to the paretic-side foot of hemiplegic patients; it sought also to provide the information needed to apply weight-bearing and balance training to hemiplegic patients. [Subjects and Methods] The subjects were divided into two groups: a spontaneous group and a step group. They all performed repetitive sit-to-stand training five times per week for a total of six weeks. The Biodex Balance System, TUG, and 5XSST were used to measure the static and dynamic standing balance of each patient. A foot mat system was used to measure foot pressure. [Results] In the balance measurements, differences in the Overall index, Ant-post index, Med-lat index, Fall risk index, TUG, and 5XSST after training was significantly different between the two study groups. In evaluating foot pressure measurements, we found that the COP (Ant-post), Peak pressure: hind foot, and Contact area: hind foot measurements significantly differed between the groups after the training. [Conclusion] Repetitive sit-to-stand training that involves positioning the non-paretic leg upward can be considered a significant form of training that improves the symmetric posture adjustment and balance of hemiplegic patients following a stroke.

The relationship between energy cost and the center of gravity trajectory during sit-to-stand motion

“…However, when the affected foot was placed behind the unaffected foot, near symmetry was obtained. When choosing therapeutic exercises, physical therapists utilize this phenomenon to treat patients with hemiplegia 16 , 17 , 18 ) . However, the reason for the achievement of near-symmetry when the affected foot is placed behind the unaffected foot is not understood.…”

Sit-to-Stand Task in Stroke Survivors: A Review Study

“…Meanwhile, the position of the asymmetric feet while standing up from a sitting position improves the static and dynamic postural balance in patients with stroke (17). In addition, the use of the step model, motion limiting strategies, repetition of sitting motion, repetitive task-oriented practice with sensory input changes, exercise on unstable surfaces, and the use of a cane and weight-bearing exercises along with biofeedback have been reported to improve the STS task in this group of patients (18,20,30,32,(35)(36)(37)(38). Interventions or training focusing on the sit-to-stand task improves the time taken to sit-to-stand and the lateral symmetry (weight distribution between the legs) during the sit-to-stand task (6).…”

“…Particularly, using the step model, in which the paretic foot is placed on the floor and the non-paretic foot on the step, has been reported to be effective in improving STS task (17). Repetitive sit-to-stand training that involves positioning the non-paretic leg upward can be considered a significant form of training to improve the symmetric posture adjustment and balance of hemiplegic patients following a stroke (18). In addition, the asymmetrical foot position during STS training results in improved balance and upright mobility in patients with chronic stroke as compared to the symmetrical foot position (19).…”

Balance und posturale Kontrolle

“…Gang auch die beidseitige symmetrische Belastung der unteren Extremität zu sein. In Untersuchungen zum Gleichgewichtstraining in der Bewegung unter forcierter Belastung des betroffenen Beines (Aufstehen und Setzen mit Schrittwechsel am Ort und Gehen) konnte die Gehbalance im Vergleich zur Kontrollgruppe mit individueller Fußbelastung verbessert werden (Timed-up-andgo-Test) [8,10].…”
