PURPOSE: The purpose of this study was to investigate the effect of trunk muscle strengthening exercises on balance performance of sitting posture and upper extremity function, targeting the children with spastic diplegic cerebral palsy. METHODS: 20 children with spastic diplegic cerebral palsy were sampled at random and the tests were conducted for 6 weeks, 3 times per week. For experimental groups, basic physical therapy and trunk muscle strengthening exercises were conducted and for control groups, only basic physical therapy was conducted. BPM(Balance Performance Monitor) was used to measure balance performance and QUEST(quality of upper extremity skills test) was used to measure the upper extremity function.
[Purpose] The aim of this study was to investigate the effects of an ankle foot orthosis
on weight-bearing abilities of stroke patients by comparing weight loading during
performance of tasks in various standing positions on the affected side. [Subjects and
Methods] This study was performed with 16 stroke patients. To measure the weight loading
value and percentage of weight loading in affected lower extremities, 5 standing tasks
were performed with and without an ankle foot orthosis in random order. [Results] In the
rising from a chair, maintaining a standing position, and forward weight shifting tasks,
the affected lower extremities showed a significantly higher percentage of weight loading
with an ankle foot orthosis. In the tasks requiring weight shifting to one leg, weight
shifting to the lateral side showed the best weight-bearing ability with or without an
ankle foot orthosis, followed by the forward and backward weight shifting, respectively.
There were statistically significant correlations in all 5 tasks with or without an ankle
foot orthosis. [Conclusion] An ankle foot orthosis improves the weight-bearing ability,
especially when shifting weight forward, resulting in increased weight-bearing ability in
activities of daily living tasks such as quiet standing and rising from a chair. The 5
tasks in this study would be a fine assessment tool under clinical conditions to
investigate the postural stability of the affected side with or without application of an
ankle foot orthosis.
[Purpose] This study was to compare the shoulder and trunk muscle activity according to
the various resistance condition during knee push-up-plus. [Subjects and Methods] Twenty
healthy adults participated in this study (9 males and 11 females). The subjects performed
dominant-leg-extended knee push-up-plus apply to resistance in the direction of abduction,
adduction, extension and the flexion. The surface Electromyography activities of the upper
trapezius, serratus anterior, homolateral external oblique and the heterolateral internal
oblique were measured. The Electromyography activities of each muscle were compared using
a one-way repeated analysis of variance. [Results] The Electromyography activities of
serratus anterior and external oblique muscles between the resistance directions were
significantly increased extension. The Electromyography activities of heterolateral
internal oblique muscle between the resistance directions were significantly increased
adduction. [Conclusion] To suggest use of the decision exercise tolerance orientation when
muscle strengthening exercises for shoulder and trunk according to variation resistance in
lower extremity during Push-up-plus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
