3 Wat je moet weten of opzoeken
Achtergrond van Sagittal Plane Fascilitation of motion. Wat is betrouwbaarheid? Wat is validiteit? MTP 1: Soort gewricht? ROM? Beweging?

4 Sagittal plane fascilitation of motion
Principles this theory is based on: The foot must be able to resist forces that are applied to it. This must co-ordinate with the power input which is required to move the body forward over the foot. The foot has its 3 autosupportive mechanisms - Dananberg, H.: Functional Hallux Limitus and its effect on normal ambulation. Current Podiatric Medicine 34, pp.1-16, 1985. - Dananberg, H.: Functional Hallux Limitus and its relationship to Gait Efficiency. JAPMA Vol.76, November, 1986. - Dananberg, H.: Gait Style as an Etiology to chronic Postural Pain, part 1 functional hallux limitus. JAPMA Vol.83, Augustus, 1993.

Autosupport 3: Locked Wedge Effect Posterior Tibial muscle and Peroneus Longus keep the base together. The shape of the bones in the midfoot are more or less trapezium shaped. In function it will support itself…

10 Uitgangshouding patiënt
Onbelast Belast

11 Uitgangshouding Therapeut
Zittend, voor de voet van de patiënt Knielend voor de voet van de patiënt

12 Differentiaal diagnose :
Hallux Rigidus = structureel Hallux Limitus = structureel Functionele Hallux Limitus = functioneel

13 RX : Hallux Rigidus = géén mobiliteit

14 Parameters Extensie mogelijkheid, open kinetische keten.
Extensie mogelijkheid mét en zonder weerstand van de therapeut. Extensie mogelijkheid mét en zonder weerstand van de GRK

15 Interpretatie Positive functional hallux limitus test
A: A load is applied to the first metatarsal head to simulate ground reaction force. B: As dorsi flexion of the toe is attempted, there is a jamming at the first metatarso phalangeal joint.

16 Interpretatie Negative functional hallux limitus test
A: Plantar flexion of the first metatarsal. B: Stability of the arch is achieved through the windlass mechanism once dorsiflexion of the first MTP joint is achieved
