What is the windlass mechanism gait?

A “windlass” is the tightening of a rope or cable. The plantar fascia simulates a cable attached to the calcaneus and the metatarsophalangeal joints. Dorsiflexion during the propulsive phase of gait winds the plantar fascia around the head of the metatarsal.

What is the Hicks windlass mechanism?

Hick’s windlass mechanism suggests that dorsiflexion of the metatarsophalangeal joint (MTPJ) during late stance produces winding of the plantar fascia around the metatarsal head (or drum of the windlass).

What produces the windlass effect?

When the foot transition from mid-stance to toe off, the toes move from a plantar flexed or neutral position to a dorsiflexed position. The dorsiflexion of the toes produces the windlass mechanism utilizing the plantar fascia.

What is foot pronation and supination?

Both terms involve your gait and how your weight is distributed as you walk or run. Supination means that when you walk, your weight tends to be more on the outside of your foot. Pronation means that when you walk, your weight tends to be more on the inside of your foot.

What does a positive windlass test indicate?

This test is positive if the patient feels pain or increased pain at the insertion of the plantar fascia at the head of the first metatarsal. If the extension is not possible at the MTP joint this may indicate a Hallux Rigidus.

What is the effect of tightening the plantar fascia during the windlass mechanism of the foot?

Stretch tension from the plantar fascia prevents the spreading of the calcaneus and the metatarsals and maintains the medial longitudinal arch. The plantar fascia prevents foot collapse by virtue of its anatomical orientation and tensile strength. A “windlass” is the tightening of a rope or cable.

What does a positive windlass test mean?

What is a positive windlass test?

A positive test is considered if passive extension is continued to end range or until the patient’s pain is reproduced. Diagnostic Accuracy: Unknown. Importance of the Test: The windlass effect is the primary mechanism that lifts the medial longitudinal arch during toe off.

What is the difference between overpronation and Underpronation?

If the inner side of the heel and forefoot show more wear, you’re an overpronator. If your shoes have more wear on the outside edge, you’re an underpronator.

Is pronation inversion or eversion?

Subtalar Joint – Secondary to the anatomy of the subtalar joint, the coupled motion of dorsiflexion, abduction and eversion produces pronation, whereas the coupled motion of plantarflexion, adduction and inversion produces supination.

Which calf muscle causes plantar fasciitis?

It is generally recognised that a tight calf muscle (which in most cases is a tight gastrocnemius) may contribute to Achilles tendinopathies and plantar fasciitis but it is less well known that the calf tightness can be linked to forefoot pathologies.
