Summary of the locomotion lesson given by prof. V. Janssens of the course physiotherapeutic theory. It is a summary of the powerpoint slides and additional items noted during the lesson. The slides were in English and my own notes are always in Dutch as much as possible. It is therefore a mix of th...

Physioth. Theory: locomotion
SUCCESFULL HUMAN LOCOMOTION

 Postural control to support the body against gravity
 Basic locomotor pattern/rythm which moves the body in the desired
direction central pattern generators
 Adaptable to the needs of the individual and the demands of the
environment
 Adaptability = supraspinal & peripheral efferents
 Invloed supra spinal niveau & info van motor cortex




CHARACTERISTICS FOR LOCOMOTION
 STABILITY: balance control
 PROPULSION of the body in the intended direction.
 ADAPTATION to potentially destabilising factors in an anticipatory way
- Voorspellende ractie
 Dual tasking: Combinations with other movement

1. IN STANCE
 STABILITY: provided through vertical forces supporting the body against gravity
 PROGRESSION: through the generation of horizontal forces against the support surface to move the body
forward
 ADAPTABILITY: strategies must be flexible enough to cope with changes in speed, direction or surface terrain

2. IN SWING
 STABILITY: gained through the repositioning of the limb in preparation for loading
 PROGRESSION is accomplished through the swing of the leg carrying it forward
 ADAPTIBILITY: is evident in the ability to avoid obstacles with the swing leg

, Physioth. Theory: locomotion
 Problems in stroke
- IC: foot flat (dropvoet)
- LR = double leg stance support
 Weight shift
 load the stance leg → not enough weight on the leg = insufficient loading
 hip extension → stay in to much flexion or to hyperextension of the hip

 Mid stance: alignment
- Absent in stroke -> no weightbearing -> no stance on one leg

 Terminal stance: rise of the heel (one leg stance)
- Further hip extension → difficult for stroke patient
 Heel off – propulsion
 Pre-swing: double leg stance support
- Weight shift
- Push-off & toe-off → push-off absent in stroke, they pull their leg forward

 Initial swing: start of swing phase
- Bringing the leg forward → pull leg forward & circumduction
- Not enough clearance when no control of foot
 Mid swing: more forward movement
- Not enough ROM → pulling leg higher
 Terminal swing

 3 rockers
- Heel rocker
 IC= hielcontact
 Hiel= support
- Ankle rocker
 Tibia over voet
- Forefoot rocker
 Push off genereren
o Goede swing samen met heupextensie
- CVA= imbalance length & strength
 Problemen 1&3 rocker
