Q

Describe myotomes and what indicates an issue

A

Myotomes are the muscles innovated by specific areas of the spinal cord nerve roots

Painless weakness indicates a nerve issue

Q

L5, S1-2 myotome innovates

A

Tibial nerve
Gastrocnemius and soleus
Plantarflexion

17
Q

L5-S1 myotome innovates

A

Sciatic nerve
Hamstrings
Knee flexion

18
Q

What are the 3 upper motor neurone tests to check brain and spinal cord

A

Babinski - run sharp edge of reflex hammer across base of foot to test plantar reflex. Abnormal if toes splay and extend
Clonus - rapid dorsiflexion. Abnormal if foot vibrates
Hoffman’s - flick middle finger. Abnormal if fingers/ thumb splay

19
Q

What does hyporeflexia indicate

A

Peripheral nerve issue

20
Q

What does hyperreflexia indicate

A

Issues with upper motor neurones (brain and spinal cord)

21
Q

Lower limb tension tests - SLR

A

Aim to stretch nerve and see if their pain is replicated
Use the straight leg raise to test sciatic
Knee extension, hip flexion and hip medial rotation

22
Q

Lower limb: how to adapt SLR for each nerve (sciatic, common peroneal, sural, tibial)

A

Sciatic: Straight leg raise with knee ext, hip flex and med rot
Common peroneal: invert and plantarflex

Sural nerve: dorsiflexion and inversion
Tibial nerve: dorsiflex and evert
Also- add neck flexion to add strain

23
Q

Types of tension test LL (3)

A

Straight leg raise - sciatic
Slump test - sciatic
Prone knee bend - test femoral

24
Q

Upper limb nerve tension tests

A

Median nerve : serve a plate (sh ab, elb ex, wrist ex)
Radial nerve : slip a tenner (sh ex, elb ex, pronate, wrist ex)
Ulnar nerve : spiderman (sh ab and lat rot, elb flex, wrist ex)

And and remove neck side flexion
