23
Q

What is spondylosis?

A

Loss of disc height or osteophyte formation that causes narrowing and compression of the nerve root

24
Q

How would someone with a disc injury (spondylosis) present?

A

Discogenic pain - where disc has been injured and becomes a nociceptive source

Centralisation

Loss of extension

High sens, low spec

25
Q

What subjective indicators may suggest centralisation?

A

If the patient says they when they do things for a long time e.g. painting the ceiling, walking for a while, up hills (extension) and the pain goes from the back of their leg

26
Q

What are the subjective indicators of disk herniation with sciatica?

A

Poor correlation between MRI and symptoms

Follows dermatomal pattern

Pain to coughing, sneezing, bracing due to an increase in intra abdominal pressure

Feeling of coldness in the legs

27
Q

What are the neurodynamic tests for disk herniation with sciatica or radiculopathy?

A

Slump

Straight Leg Raise

High Sens, Low Spec

28
Q

When is a MRI useful in Lx pain?

A

Red flags

Severe nerve root compression

29
Q

What model is important to consider with Lx pain patients?

A

Biopsychosocial model

30
Q

How can you differentiate between specific and non-specific back pain?

A

Exclude the specific causes

31
Q

What is sciatica?

A

Neuropathic leg pain secondary to compressive spinal pathology e.g. spondylosis

Pain involves the sciatic nerve

32
Q

What would sciatica look like on a body chart?

A

P1 - Ache or stabbing unilateral pain in the Lx

P2 - Superficial intermittent ache down the leg

P2 only comes on when P1 has been painful

33
Q

What are the subjective questions should you ask regarding sciatica?

A

Sitting, standing or walking posture

Specific occupation function regarding biomechanics

34
Q

What dictates the structure of the objective assessment?

A

Severity and irritability

35
Q

What position is spondylolisthesis most painful?

A

Extension

36
Q

What position is most painful for a disc injury?

A

Sitting for long periods

37
Q

What is a typical of patients with stenosis?

A

Can only walk for a period of time before getting stenotic symptoms down the leg

38
Q

What are blue and black flags?

A

Blue - Occupational e.g. litigation, insurance, work status

Black - Socio-occupational e.g. work satisfaction, work conditions, do they enjoy work? how long have they worked there for?

39
Q

What are orange flags?

A

Psychiatric status e.g. suicidal, severe depression

40
Q

What are pink flags?

A

Positive attitudes, good motivation, etc.

41
Q

How does anxiety and depression affected Lx pain?

A

Amplify pain

42
Q

What is the STarT Back Tool

A

A stratified care screening tool that includes 9 questions (good sens and spec in primary care)

Medium risk - Referral to physical therapy

High risk - Refer to psychologically informed physical therapy e.g. senior physio

Q

What is effective self management for LBP?

A

Provide advice and information tailored to individuals needs and capabilities to help them self-manage

Information on the nature of LBP and sciatica

Encourage to continue with normal activities

44
Q

What type of exercise is effective for LBP?

A

Group exercise programme e.g. bio-mechanical, aerobic, mind-body or a combination

47
Q

What are the effective pharmacological interventions for LBP?

A

51
Q

What are the clinical features of spondylolisthesis?

A

Localised Lx pain

Increased pain with flexion and extension leading to reduced ROM

Increased pain on palpation

Narrowing leads to nerve root compression and symptoms down leg

Pain relieved lying supine

Hamstring spasm

Disturbances in coordination and balance

52
Q

What is spinal stenosis?

A

Narrowing of the spinal canal

Caused by degeneration which can involve disc bulge, osteophyte formation and a thickened posterior longitudinal ligament

53
Q

What are the clinical features of spinal stenosis?

A

Increase in pain with prolonged walking and standing with lumbar extension

Relieved by forward flexion and rest

Pain increased on single leg stance

55
Q

Name 2 ways that the nerve root can be affected causing pain from a disc herniation

A

Physical compression of the nerve from the disc herniation

Disc herniation releases chemicals that cause inflammation of the nerve root
