The stretch reflex (myotatic reflex) is a muscle contraction in response to stretching within the muscle. It is a monosynaptic reflex which provides automatic regulation of skeletal muscle length. When a muscle lengthens, the muscle spindle is stretched and its nerve activity increases.
Some reflexes, such as the muscle stretch reflex, are semi-quantitatively graded. This is also true for responses such as the pupillary light reflex, where the speed of reaction may indicate a sluggish response. On the other hand, many reflexes are simply noted as present or absent.ormal muscle stretch reflexes result in contraction only of the muscle whose tendon is stretched and the agonist muscles (i.e., muscles that have the same action). There is also inhibition of antagonist muscles. Reflexes are graded at the bedside in a semi-quantitative manner.
