Spine and balance Flashcards
Lordotic posture
Ant pelvic tilt
Increase hip flex
Cause: Faulty posture, pregnancy, obesity, weak abd muscles
Slouched posture
“sway back”
Ant shift in the pelvis
Hip ext
Posterior thoracic shift
Thoracic and upper lumbar spine flexion
increase lordosis
Increased kyphosis
Flat low-back posture
Decreased lumbar lordosis
Hip ext
Posterior pelvic tilt
Causes: cont slouching, flexion in sitting or standing. Overemphasis on flex exercises
Increase Kyphosis, Forward head
Increased thoracic curve
protracted scapula
increased flex of lower cervical/upper thoracic
increased ext of upper cervical, ext of occiput on C1
M. impairments: pec major/minor, lats, Serratus ant, Levator, SCM, scalene, upper trap, lower cerv, thoracic erector spinae
weight shifting strategy
Utilized to control mediolateral perturbations by shifting the body weight laterally from one leg to the other.
The hips are the key control points (hip ABD/ADD)
Hip strategy
Utilized with rapid and/or large external pertuberbations or for mvmnts executed with the COG near the limits of stability.
Rapid hip flex or ext is used to move the COM within the BOS
stepping strategy
Seen with large force displacements of the COM beyond the limit of stability; A forward or backward step is used to enlarge the BOS and regain balance control
