always indicated in the presence of peripheral pain which could be referred from the spine - if neurological testing isnt completed when indicated, it is unsafe
pain referred to or past the buttock/shoulder
altered sensation - paraesthesia or anaesthesia
referred pain from spine can be nociceptive pain or neuropathic pain
any changes found in neurointegiry testing will support that the referred pain is neural in origin
this should then be performed during/at each session dependent on clinical presentation to monitor for improvement or worsening of symptoms
Upper motor neurone testing:
indications: part of any full neurological testing
unsteadiness of gait
bilateral non-dermatomal distribution of symptoms
exaggerated tendon reflex response
bowel or bladder dysfunction - can also implicate cauda equina compression
Babinski
Clonus
reflexes:
biceps - C5 (mainly) and C6
brachioradialis - C5 and C6 (mainly)
triceps - C7
Babinski:
test for upper motor neurone lesion
normal response: no change in pts toe positions, curling and flexion of toes is also normal
positive response (upper motor neurone lesion): big toe extension with fanning of the other toes
compare to the other side
Clonus:
test for upper motor neurone lesion
normal response: 0 to 3 beats of the foot into plantarflexion
positive response (upper motor neurone lesion): foot continues to beat into plantarflexion for more than 3 beats
compare to the other side
Upper & Lower motor neurone testing - Reflexes:
assess the integrity of the afferent and motor connections as well as the general sensitivity of the nervous system
hyper reflexes indicates a problem within the CNS assessing for an upper motor neurone lesion
hypo reflexes indicates a lower motor neurone lesion
Upper & Lower motor neurone testing - Reflexes:
Biceps - C5 mainly and also C6
pts seated, relaxed
your thumb should be placed over biceps tendon and elbow should be just off full extension
strike your elbow - look for contraction of the biceps with associated elbow flexion movement
Upper & Lower motor neurone testing - Reflexes:
Brachioradialis - C6 mainly and also C5
pts seated, relaxed
thumb should be 1 to 2 cm inferior to the lateral epicondyle on the muscle belly of brachioradialis, apply gentle medial glide to induce a stretch onto the tendon
strike thumb - look for contraction of brachioradialis muscle bell and associated elbow flexion movement
Upper & Lower motor neurone testing - Reflexes:
Triceps - C7
strike tendon directly just superior to where it inserts onto the olecranon
look for muscle contraction in triceps muscle belly with or without associated elbow extension
Myotome:
checks for lower motor neurone lesions
a myotome is a muscle or muscle group supplied by a spinal nerve
Myotome:
C1 - cervical flexion
C2 - cervical extension
C3 - cervical lateral flexion
C4 - shoulder girdle elevation
C5 - shoulder abduction
C6 - elbow flexion
C7 - elbow extension
C8 - thumb extension
T1 - finger adduction
Dermatome:
check for lower motor neurone lesions
a dermatome is an area of skin supplied by a spinal nerve
make sure pts close their eyes, test unaffected area first, compare both side
not to be confused with cutaneous/peripheral - area of skin supplied by a branch of a nerve root
if there is dermatomal problems - can further investigations via sharp/blunt or hot/cold
