In terms of scoring deep tendon reflexes, which of the following scores would be given for an active or expected response?

Correct Answer:
2+
in terms of scoring deep tendon reflexes, a 2+ score represents an active or expected response. this grading system is widely used in neurological examinations to assess the integrity of the reflex arcs at various levels of the central and peripheral nervous system. here is a breakdown of the scoring:

0: no response – this score indicates that there is no observable contraction of the muscle or movement of the limb when the tendon is tapped. a score of 0 can suggest neurological impairment or damage at specific sites within the reflex arc.

1+: trace response – this is a minimal but definitely present response. it can be seen as a slight movement or contraction but is less than what would be considered normal. this response might be seen in cases of slight neurological impairment.

2+: normal or active response – this score is considered the standard normal response where there is a clear, brisk contraction of the muscle that moves the limb appropriately when the tendon is tapped. this is the expected response in healthy individuals without neurological deficits.

3+: brisk response – this is more pronounced than a normal response and may indicate an exaggerated reflex. it is not necessarily indicative of neurological disease but might suggest some level of increased nervous system excitability.

4+: very brisk response – this score is characterized by a very vigorous reflex response and often includes associated movements in other muscles (a phenomenon known as spread of reflex). a score of 4+ might also include intermittent or transient clonus, which is a series of involuntary rhythmic muscle contractions occurring in response to sudden stretching of the muscle. this high score can be indicative of neurological conditions that involve upper motor neuron pathways, such as stroke or multiple sclerosis. the scoring of reflexes helps in diagnosing and monitoring diseases of the nervous system. a score of 2+ is considered normal and is the target response during a standard neurological examination. this scoring system allows clinicians to quickly assess the reflexes and provide a quantitative measure that can be tracked over time or after interventions.
