Neuromuscular Control of the Trunk during Sitting Balance
Sitting stability is maintained by continuous and intermittent activation of trunk and lower limb muscles. However, spinal cord injury (SCI) can result in paralysis of the trunk muscles and affects sitting balance. Currently, chest straps and trunk braces are used to correct sitting after SCI. In addition to these passive devices, functional electrical stimulation (FES) could be used to artific...
متن کاملTrunk control in unstable sitting posture during functional activities Running Title : Balance in sitting
Objectives: To examine trunk stability in unstable sitting posture in two different functional activities. Design: A randomized crossover design. Participants: Ten healthy subjects and ten patients suffering from MS. Interventions: A task in which the subjects had to keep their trunk as stable as possible was compared with tasks in which they had to track an object with the head or grasp an obj...
متن کاملCenter of pressure trajectories, trunk kinematics and trunk muscle activation during unstable sitting in low back pain patients.
Trunk motor behavior has been reported to be altered in low-back pain. This may be associated with impaired lumbar proprioception, which could be compensated by trunk stiffening. We assessed trunk control by measuring center-of-pressure, lumbar kinematics and trunk muscle electromyography in 20 low-back pain patients and 11 healthy individuals during a seated balancing task, in conditions with ...
متن کاملFiber optic angular displacement sensor
A reflective type fiber optic angular displacement sensor has recently been developed, which consists of a light source, an optical isolator, a four-port single-mode fiber bidirectional coupler, and a light intensity detection system (two silicon photodetectors and ananalog divider). By using a normal He-Ne laser with &2% stability in light intensity, we have achieved an angle resolution of 10e...
متن کاملDynamic stability of the trunk during unstable sitting in people with low back pain.
STUDY DESIGN Cross-sectional study. OBJECTIVE To evaluate the dynamic stability and kinematics of the trunk during unstable sitting, and to determine the differences in these biomechanical parameters between healthy participants and participants with low back pain (LBP). SUMMARY OF BACKGROUND DATA Patients with LBP exhibited alterations in trunk kinematics while performing different dynamic...
