Case Studies

CASE 1: 45-year-old male 2 months of symptoms, worsening. Relates to car accident when there was a mild shunt from behind. - Headache +dizzy on lying down and rolling in bed; - Spinning of room lasting only seconds - Nausea++; - no aural symptoms Health - fine

Differential Diagnosis Reasoning - Likelihood of a vascular Red Flag? HIGH LOW - If HIGH, can you identify the probable pathology?:________________________________ - If LOW, provide two possible alternative diagnoses: 1) ___________________________________ 2) ___________________________________ - Can you manage this patient with Physical Therapy as a primary management strategy? YES NO - Comments of differentiation (supporting/negative evidence): ____________________________________________________________________________________

CASE 4: 42 year old male -Neck pain (to jaw) / headache (side) 1/12 -History of migraines but “not had this type of pain before” -Thinks he “pulled muscle” in throat because has difficulty swallowing food/drink. Health -High BP; been doing “McKenzie” neck exercises = worsening.

REASONING

Future directions …. Why?

• Much debate over the past decades regarding: – Risks associated with cervical treatment e.g.

Manipulation/mobilisation – Examination of the cervical region for a vascular

component to clinical presentations

• Confusion for clinicians

• Time for a paradigm shift?

Objective (IFOMPT)

• To provide an update on current thinking to inform practice when examining a patient presenting with cervical spine dysfunction – Cervical Artery Dysfunction – Rushton A, Rivett D, Carlesso L, Flynn T, Hing W, Kerry R

• International Framework for Examination of the Cervical Region for potential of Cervical Arterial Dysfunction prior to Orthopaedic Manual Therapy Intervention

Aims of the IFOMPT framework

• To provide guidance for the assessment of the cervical spine region for potential of Cervical Artery Dysfunction (CAD) in advance of planned Orthopaedic Manual Therapy (OMT) interventions

• Consensus document to be agreed by 22 IFOMPT countries (2012)

Sections of the IFOMPT framework

1. Context to assessment of the cervical region 2. Clinical reasoning as a framework 3. Patient history 4. Planning the physical examination 5. Physical examination 6. Risk v benefit analysis 7. Flowchart of clinical reasoning 8. Informed consent and medico-legal framework 9. Safe OMT practice, including emergency management of an adverse

situation 10. Teaching OMT for the cervical region 11. Proposed response to the media: key messages to communicate 12. References

Neurological examination (IFOMPT)

• Examination of; – peripheral nerves – UMN – cranial nerves

… will assist in evaluating the potential for neuro-vascular conditions see Fuller [2008] for a detailed description of how to perform testing or www.neuroexam.com

4. Planning the physical examination (IFOMPT)

• Careful planning of the physical examination is required

• In particular for the IFOMPT framework …

• “The possible vasculogenic (cervical arterial)

contribution to the patient’s presentation needs to be clearly evaluated from the patient history data”

IFOMPT (cont’ …)

Are any further patient history data required? • An important component of planning is the

identification of any further patient history data that may be required – Are there any gaps in the information obtained? – Is the quality of the information obtained

sufficient?

IFOMPT on …. Physical examination - Decision-making

• The physical therapist needs to decide: – Are there any precautions to orthopaedic manual

therapy (OMT)? – Are there any contraindications to OMT? – What physical tests need to be included in the

physical examination? – What is the priority for these physical tests for this

specific patient? – Do the physical tests need to be adapted for this

specific patient?

More questions than answers . . . !

Physical examination • Blood pressure

• Cranial nerve examination • Pulse palpation/auscultation • Eye examination • Proprioception tests (Romberg’s; Tandem gait) • VBI test? • Instability testing? • US Doppler??

Physical examination (Kerry & Taylor) • Blood pressure

• Cranial nerve examination • Eye examination • Pulse palpation/auscultation • Proprioception tests (Romberg’s; Tandem gait) • VBI test • Instability testing? • US Doppler??

Blood pressure?

• Is it part of your examination?

• Case study …. NOT RCT!!

Cranial nerves?

• Upper limb?

• Lower Limb?

• UMN?

• Cranial nerves . . . Are they part of your examination?

“Cranial nerves . . . That would take forever!!”

What is physiotherapy?

• “Physiotherapy is a health care profession concerned with human function and movement and maximising potential:

• it uses physical approaches to promote, maintain and restore physical,

psychological and social well-being, taking account of variations in health status

• it is science-based, committed to extending, applying, evaluating and

reviewing the evidence that underpins and informs its practice and delivery

• the exercise of clinical judgment and informed interpretation is at its

core.”

Neck rehab …. ?

Are we ‘maximising potential’ …. ?

Are these Muscular Changes a

Unique Feature of Persistent WAD?

But questions remain….

…muscle changes have been quantified

SUMMARY

•WAD patients show objective evidence of muscle changes on MRI

•Whiplash injuries are different from non-traumatic neck pain

•Fatty infiltration occurs only in whiplash patients

•The cause and exact timing of this phenomenon remains unknown

•There may be a case for sensorimotor assessment of patients Elliott J, Jull G, Noteboom JT, Galloway G.
