Coordination Impairments (Hypertonia/Spasticity, Motor Ataxia, Dyskinesia): The following three criteria should apply: (1) Spastic/ataxic/athetoid hemiplegia/diplegia/quadriplegia/monoplegia with moderate involvement of lower limb but with no or very mild involvement of upper limbs. (2) Demonstrate a limitation in function based on spasticity, ataxia, athetosis or dystonic movements while performing during match or training. The Player may walk with a slight limp but runs more fluidly. (3) Clear evidence must include spasticity grade 1-2 in the affected limbs (at least one leg must be affected). A clear difference needs to be demonstrated between active ranges of motion vs. passive. In addition, a clear difference between fast PROM against slow PROM needs to be demonstrated. Plus ONE of these signs: 1) Upper motor neuron reflex pattern must be demonstrated (one of the following signs): Positive unilateral Babinski. Clear unilateral clonus four beats or more. Noticeably brisk reflexes or clear difference in reflexes left vs. right leg. 2) Irregular migrating contraction (chorea) and/or writhing movements (athetoid). 3) Leg length difference and/or difference of muscle bulk of more than 2 cm. 4) Dysmetria and/or dyssynergia. In monoplegia the hip joint must be involved with limitation in PROM or difference in ROM active versus passive. For ataxia and athetosis the Player must have clear signs of cerebellar dysfunction with incoordination of the lower limb. Shows moderate difficulty in stopping, starting, turning, balance and explosive movements.

Limb Deficiency: 1) Unilateral amputation of half of the foot, measured on the non-amputated foot from the tip of the great toe to the posterior aspect of calcaneus. OR 2) Congenital Limb Deficiency or dysmelia equivalent to the above description.

Leg Length Difference: The difference in length between right and left leg should be at least 7 cm. Measurements to be taken from the inferior aspect of the anterior superior iliac spine to the most medial tip of medial malleolus on same side.

Impaired Passive Range of Movement: Impairment of PROM that meets TWO of the following criteria in one or both lower limbs: 1) Hip flexion deficit of 45 degrees. 2) Hip Extension deficit of 25 degrees. 3) Knee Flexion deficit of 60 degrees. 4) Knee Extension deficit of 30 degrees. 5) 10-degree ankle dorsiflexion and a maximal ankle PROM of 10 degrees. 6) 20-degree plantar flexion and a maximal ankle PROM of 10 degrees.

Impaired Muscle Power: Impairment of Muscle Power that meets TWO of the following criteria in one or both limbs: 1) Hip flexion loss of 3 muscle grade points (muscle grade of two). 2) Hip extension loss of 3 muscle grade points (muscle grade of two). 3) Hip Abduction loss of 3 muscle grade points (muscle grade of two). 4) Hip Adduction loss of 3 muscle grade points (muscle grade of two). 5) Knee flexion loss of 3 muscle grade points (muscle grade of two). 6) Knee extension loss of 3 muscle grade points (muscle grade of two). 7) Ankle plantar flexion loss of 3 muscle grade points (muscle grade of two). 8) Ankle dorsiflexion loss of 3 muscle grade points (muscle grade of two). OR Back and Torso: Severely reduced mobility of a permanent nature, for example scoliosis measuring over 60 degrees curve as measured by the Cobb method. X-ray proof is necessary.
