DEFINITIONS

Hyper-reflexia: a condition in which the deep tendon reflexes are exaggerated; overactivity of physiological reflexes (in other words, my body over-reacts to anything that unexpectedly touches me)

Spasticity: muscular hypertonicity with increased tendon reflexes (iow, my muscles are not able to relax)

Dystonia: literally, "abnormal muscle tone"; generic term used to describe a neurological movement disorder involving involuntary, sustained muscle contractions. Dystonia may affect muscles throughout the body (generalised), in certain parts of the body (segmental), or may be confined to particular muscles or muscle groups (focal).

EDIT: I learned from my neurologist that dystonia is actually the opposite of my problem.
