The effect of spinal orthosis on trunk muscle force control in hyperkyphotic elderly
Background: The back extensor muscles are the main spinal supportive factors which function establishes spinal stability and erect posture of the spine. Spine deviation from the ideal alignment, like abnormal increase in the forward curvature of the thoracic spine may cause changes in the trunk muscle activity which can lead to a change in the spinal proprioception. It seems that the corrected ...
متن کاملComparison of trunk muscle forces and spinal loads estimated by two biomechanical models.
BACKGROUND Comparative studies between single-joint electromyography (EMG)- and optimization-driven models of the human spine in estimating trunk muscle and spinal compression forces have not been conclusive. Due to associated implications in ergonomic applications as well as prevention and treatment managements of low-back disorders, there is a need to critically compare existing single- and m...
متن کاملTrunk Muscle Activity Is Modified in Osteoporotic Vertebral Fracture and Thoracic Kyphosis with Potential Consequences for Vertebral Health
This study explored inter-relationships between vertebral fracture, thoracic kyphosis and trunk muscle control in elderly people with osteoporosis. Osteoporotic vertebral fractures are associated with increased risk of further vertebral fractures; but underlying mechanisms remain unclear. Several factors may explain this association, including changes in postural alignment (thoracic kyphosis) a...
متن کاملDegree of thoracic kyphosis and peak torque of trunk flexors and extensors among healthy women☆☆☆
OBJECTIVE The aim of this study was to analyze the effects of aging on the degree of thoracic kyphosis and peak torque of the trunk flexor and extensor muscles among women without a densitometric diagnosis of osteoporosis. METHODS Thirty women were selected to make up three groups: young women (n = 10; 24.60 ± 2.27 years of age); adults (n = 10; 43.50 ± 2.88); and elderly women (n = 10; 62.40...
متن کاملTrunk muscle activation in a person with clinically complete thoracic spinal cord injury.
OBJECTIVE The aim of this study was to assess if, and how, upper body muscles are activated in a person with high thoracic spinal cord injury, clinically classified as complete, during maximal voluntary contractions and in response to balance perturbations. METHODS Data from one person with spinal cord injury (T3 level) and one able-bodied person were recorded with electromyography from 4 abd...
