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.
Modifications:
Flex stance-leg knee and hip to increase dorsiflexion and emphasis on soleus.
Contraindications:
Pain associated with sciatica.
Fused ankle joint.
Plantar flexor contracture.
