The Hubscher maneuver or Jacks test is a clinical assessment that involves dorsiflexing the hallux in the weightbeairng foot and estimating the force needed to raise the arch of the foot. This test is a measure of the integrity of the windlass mechanism of the foot.
The Hubscher maneuver, also known as the Hubscher test or the Windlass test, is a clinical examination technique used to assess the integrity and function of the plantar fascia, a thick band of tissue that supports the arch of the foot.
To perform the Hubscher maneuver, the following steps are typically followed:
- The patient is asked to lie down on their back, with their legs extended.
- The examiner then stabilizes the patient’s leg and grasps the toes of the foot being tested.
- With the examiner’s other hand, the foot is dorsiflexed (pulled upwards) at the ankle joint.
- While maintaining this dorsiflexion, the examiner observes for any changes or symptoms in the plantar fascia and the patient’s response.
The Hubscher maneuver primarily assesses the tension and function of the plantar fascia. When the foot is dorsiflexed, tension is applied to the plantar fascia, and if it is intact and healthy, it should cause a tightening and lifting of the arch of the foot. This lifting of the arch is known as the Windlass mechanism. If there is pain or limited range of motion during this maneuver, it may suggest plantar fasciitis or other conditions affecting the plantar fascia.
