The Spine Kinematics and Center of Pressure Excursion During Functional Task Vertebral Compression Fractures Subjects

Taichung Veterans General Hospital46 enrolled

Overview

This study aimed to assess the sensory and kinematic components of the limits of stability (LOS) test in patients with vertebral compression fracture (VCF) .

This study enrolled adults with VCF (VCF group), older adult without spinal deformity (NE group), and young adults (NY group). The Biodex balance system was employed to calculate the balance score and the LOS of participants. An inertia motion system was used to record kinematic data. The center of pressure (COP) signals of postural stability and LOS were used to calculate the frequency power spectrum for interpreting the sensory component.

Vertebral compression fracture Inclusion Criteria: older than 65 years osteoporosis diagnosed by a bone mineral density test of the lumbar spine (T-score \< -2.5; T: peak bone mass) thoracic-lumbar VCF on radiography without displacement Vertebral compression fracture Exclusion Criteria: other spinal diseases that might also cause back pain (such as scoliosis, lumbar spondylolisthesis, lumbar disk disease, and spinal stenosis) a history of diabetes a history of neurological disease (such as cerebral vascular disease, peripheral neuropathy and vestibular disease). Control Inclusion Criteria: None the control participants had evidence of gait, postural, or spine disorders.

Outcomes

Primary Outcomes

Postural Stability

A balance system was employed to calculate the standing posture sway score.A high score was indicative of excessive movement during the test and thus, poor stability. The range of value was 0.3- 4.1.

Time frame: 90 second

limits of stability

patients shift their center of gravity from the center target to a blinking target and back to the center target.This process was repeated for each of the 9 targets. A high score was indicative of fine direction control.The range of value was 21- 66.

Time frame: 1-2 minutes

Kinematic Data

The movements of the head, upper spine, lower spine, pelvis,hip, thigh, and knee were measured using 6 inertial measurement units.

Time frame: 5 minutes

timed up-and-go test

sit-stand-walk-180° turning-walk and sitting down task

Time frame: 90 second
