1 Cortical change in chronic low back pain
-Chronic low back pain is characterised by a range of structural, functional and neurochemical changes within the brain. Functional changes in individuals with chronic low back pain are reflected in a cortical reorganization, altered cortical activity and altered cortical responsiveness.
2 Lifting weights can change the brain
3 Importance of varying running surfaces
4 Emergence of postural patterns as a function of vision and translation frequency.
J Neurophysiol. 1999 May;81(5):2325-39.
Our results suggest that visual information was important to maintaining a fixed position of the head and trunk in space, whereas proprioceptive information was sufficient to produce stable coordinative patterns between the support surface and legs. *The CNS organizes postural patterns in this balance task as a function of available sensory information, biomechanical constraints, and translation frequency.
5 Previous hamstring injury is associated with altered kinematics.
“Previously injured athletes demonstrated significantly reduced biceps femoris muscle activation ratios with respect to ipsilateral gluteus maximus, ipsilateral erector spinae, ipsilateral external oblique, and contralateral rectus femoris in the late swing phase. We also detected sagittal asymmetry in hip flexion, pelvic tilt, and medial rotation of the knee effectively putting the hamstrings in a lengthened position just before heel strike.”
