LEVEL C: Active Rotational Single Leg Calf

Functional Purpose

Biomechanical Outcomes:

Pre-positioning the ankle joint into passive dorsiflexion creates a biomechanical platform towards enhancing 3-dimensional ankle mobility once active component of exercise initiates.

Implementing principles of mass & momentum, as the non-stance leg moves inside & outside the axis of the ankle joint, there is a global caudal effect resulting in subtalar pronation / supination and calcaneal eversion / inversion coupled with talo-crural dorsiflexion.

Neurological / Physiological Outcomes

In response to the pre-positioned passive dorsiflexion and upright posture, the posterior longitudinal sling contracts / becomes facilitated & enhances tensional-stability globally.

Promotes an increase in connective tissue elasticity and resiliency associated with triplane motion of the ankle.

Encourage optimal motor unit recruitment and enhance sensory-motor integration involved with triplane ankle mobility.

Psycho - Social Outcomes:

Safely challenge any (subjective) maladaptive perceptions, beliefs and/or past experiences associated with upright subtalar eversion & inversion and loaded dorsiflexion.


Flex stance-leg knee and hip to increase dorsiflexion and emphasis on soleus.


Pain associated with sciatica.

Fused ankle joint.

Plantar flexor contracture.
