Spasticity

Question 1

Pathophysiology of Spasticity

Answer 1

stretch reflexes are most basic neural circuit contributing to muscle tone
modulated by excitatory and inhibitory influence
imbalance in these results in hyper excitability of stretch reflex arc

Question 2

Non-neural factors

Answer 2

muscles in a shortened position- loss of sarcomeres with increased shortness and stiffness
can lead to contractors
immobility: remodelling of connective tissue, resulting in increased stiffness of muscle
