Postural Control POSTURAL ORIENTATION INTERNAL REPRESENTATION BODY CONCEPTAwareness
Postural Control § POSTURAL ORIENTATION § INTERNAL REPRESENTATION § BODY CONCEPT(Awareness, Schema, Image) § SENSORY CHANNEL § MUSCULOSKELETAL COMPONENT § NEUROMUSCULAR COMPONENT
SHOULDER HEAD CONTROL SCAPULAR ELBOW HAND PROXIMAL (ALIGNMENT) PELVIS HIP KNEE ANKLE MOVEMENT
STATOKINETIC REACTION § STABILITY/MOBILITY = WORKS TOGETHER WHILE DOING SOMETHING. (PURPOSEFUL MOVEMENT) =WE CALL IT POSTURAL CONTROL =BASE OF MOVEMENT =RR. ER. SR
CENTRAL PATTERN GENERATOR § POSTURAL ALIGNMENT § MOVEMENT § ACTIVATION FROM THE MUSCLES § PROGRAMED MOVEMENT § INFORMATION
CENTRAL PATTERN GENERATOR § Spinal circuits as central pattern generators § The existence of pacemaker cells within neural tissue demonstrate the ability for circuits to be active without sensory input. § The overall stepping pattern consists of a rhythmic alteration in the contractions of flexor and extensor muscles. § The pattern of the pattern generator is written into the CNS map I. e. it is genetic
CENTRAL PATTERN GENERATOR § Each limb has it’s own pattern generator each of which can act independently of the other generator § The limbs are timed spatially and temporally by cerebellar control
ASSESSMENT MUSCLE LENGTH DIRECTION STRENGTH SYNERGIST R. O. M SKELETAL DIRECTION LENGTH SIZE MOBILITY
FETAL MOVEMENT § Body concept - midline, Each direction § Confidence – Security § Neuromuscular junction - Motor output unit Musculoskeletal structual component
NEW BORN BABY v Physiological flexion status - From approximately 32 weeks - Security/ going home - Flexion means elongates mainly trunk and Neck muscles.
NORMAL DEVELOPMENT 1 st Step Elongation of each muscles (One plane) 2 nd Step Elongation of each muscles(variety) Strengthening the muscles
HEAD CONTROL I Vestibulocollic reflex Vestibulospinal reflex Vestibuloocular reflex Optokinetic reflex Tongue Maseters * Base of support * Trunk control, rib cage, scapular * Neck elongation * Shape of head
HEAD CONTROL II v Starting from rolling to side v Rolling means -Neck space(Elongation) -Dissociation from the shoulder & Arm, Trunk, Lower part of the body -Dissocition each part of the body
HEAD CONTROL III Too much movement than trunk - compensatory movement Mirror of postural control Neck space Chin tuck Hyperextened neck
HEAD CONTROL IV Moves in together Hyperextended neck and Back Muscle Adducted scapular Pull back the pelvis as a PUMP = LACK OF PROXIMAL STABILITY
UPPER ARM HEAD SCAPULAR RIB CAGE ABDOMINAL M. VISION * HEAVY ARM * FIXATION OF SCAPULAR * COMPANSATORY HEAD FIXATION * UPWARD GAZE
TRUNK § Back muscle group -stereotyped direction -changing direction a) less movement b) too short c) asymmetry
SITTING(1) Alignment + BOS Weight bearing on bone, skin, muscle, ligaments etc. Trunk moves against Pelvis by muscle of tummy, hip and legs Pelvis should be stabilized -- moves laterally
SITTING(2) Ankle stabilize the proximal part of body Ankle guides changing of COG Ankle is the signal of picture of the Pelvis
STANDING UP § NORMAL § ABNORMAL 1)Tibiallis anterior 2)Rhomboides 3)Trapezius 4)Quadriceps 1) 2) 3) 4) Rhomboides Trapezius Tibiallis anterior Quadriceps
STANDING Alignment COG tends to move forward because of instability on trunk and pelvis -Especially, poor structure of abdominal muscles and stereotyped direction of the back muscles
