Passive control of posture
|
-ligaments, bones, capsules
-provide low-load passive tension -provide input to CNS through receptors -assist maintaining stability with good posture -will creep if excessively loaded(one leg longer than the other) **always providing feedback to CNS-when you assume a posture a lot this becomes your normal posture -intervention-reset neural impulses to bring back to neutral |
|
active control of posture-multisegmental muscles
|
muscles: multisegmental
-longer moment arms -responds to movement -little segmental stability -abdominals, quadratus lumborum, Erector spinae, illiopsoas, SCM, Levator Scap, Upper trap **superficial further away from joints of spine-help maintain posture and help with movement in and out of posture |
|
neural control of posture
|
feedforward control-
muscle response/activation in anticipation of an imposed load, e.g.. extremity movement. -transversus abdominus -multifidus-anticipate this and contract before action |
|
Control of posture-Elements
|
1passive control-ligaments, bones, capsules
2active control-muscles, multi segmental and intersegmental 3neural control |
|
active control of posture-intersegmental muscles
|
shorter moment arms
-provide segmental stability -transversus ab, multifidus, deep quad lumb, deep rotators, rectus captious anterior and laterals, longs collie deep active control segment to segment |
|
Breathing affect on posture and posture control
|
transversus, intercostals, and diaphram,
-creating intraabdominal pressure -valsalva |
|
poor posture
hyperlordotic posture |
anterior pelvic tilt and lumbar extension
-increased L-5 Angle -Increased anterior shear lower lumbar spine -->spondylolisis and spondylolisthesis |
|
poor posture:
slouched posture (swayback) |
variable pelvic tilt
-hip extension --hanging on hip ligaments Upper thoracic flexion forward head |
|
Poor posture:
Rounded back and forward head |
increased thoracic kyphosis
-scapular protection -lower cervical flexion -subcranial extension--?region becomes tight **swimmers and weightlifters -headaches come up over top of head interactions-nodding exercises traction of occiput on C-1 --soft tissue |
|
Postural re-education:
Multi-faceted -no single solution --requires |
no single solution
--requires constant reminding -replaceing old habits with new habits ---Will take time ---That was NOT easy _treat the 3 legged stool(strength, stretch, cardio) --***reminders-little red sticky dots -every time see one they sit up straight --driving -get seat back where it belongs and adjust the rearview mirror for that position |
|
Elements of Postural re-education
- |
Postural awareness and spinal control
-relationship between posture, movement, and function -tissue impairments -muscle performance -body mechanics and ergonomics -stress and relaxation |
|
Postural awareness and spinal control
|
whole-part-whole
--lean individuals postural movements --axial extension ---scapular retraction ---pelvic tilt *exaggerate normal posture, and then settle into new posture |
|
Relationship between posture, movement, and function
|
recognize pain changes with posture changes
-demonstrate extremity function with posture changes **good posture then exercise feeds neural feedback loop |
