A person could have somewhat adequate hand function statically, but may have less function when throwing due to athetoid involvement. Although function may improve or worsen in this area when in the water, evaluation of very poor arm, hand and leg function for propulsion should make this class clear. Severe athetoid or tetraplegic with fair function in less affected side. Poor functional strength in all extremities and trunk but able to propel a wheelchair. Class 2 lower athletes can sometimes ambulate.
Static control is fair.
Severe to moderate involvement. Spasticity Grade 3. If hand and arm function is described as in Class 1 then lower extremity will determine whether Class 2 is more appropriate. Throwing motions must be tested for effects on hand function. Wheelchair propulsion with upper extremities is also demonstrable.
