Musculoskeletal foundations for the APC Written Assessment: build a useful initial plan
Work through an original low back pain scenario to practise screening, imaging decisions, shared goals, activity advice and reassessment for the APC exam.
Published 2026-10-10.
Musculoskeletal revision can become a list of tissue labels and special tests. A more useful exercise is deciding what information you need before treatment, how findings change the plan and what meaningful improvement would look like to the patient.
This original low back pain scenario focuses on an initial consultation. It is an educational example, not an official APC question or a complete musculoskeletal syllabus. Fractures, postoperative restrictions and other regional presentations require their own reasoning; the plan here should not be applied to them automatically.
An original worked scenario
Maya, 38, reports six days of low back pain that began after moving several boxes at home. She has stopped her usual walks and is avoiding work because she worries that bending will damage a disc. She asks for an MRI before doing any exercise. Her main goal is to manage a half-day at her desk and resume walking with her child.
A targeted history finds no significant trauma, constitutional symptoms, cancer history, new bladder or bowel disturbance, saddle sensory change or progressive leg weakness. Examination identifies painful, guarded lumbar movement, but no focal neurological deficit. The clinician considers her overall history and examination and does not identify a current indication of serious pathology. She can walk and change position independently.
A useful summary is a recent episode of low back pain affecting work and family activity, with substantial concern about movement and no current indication of serious pathology on assessment. This is more informative than assuming a particular disc lesion from the lifting event.
Decision 1: establish a working assessment
The Australian Low Back Pain Clinical Care Standard supports a targeted history and examination, consideration of serious causes and assessment of psychosocial factors. Clinical reasoning uses the whole presentation; a checklist of absent features is not a guarantee that nothing important can emerge later.
In this example, ask Maya what she believes has happened, which activities she avoids and what she has been told about bending. Clarify work demands, sleep, previous episodes and what support is available. Observe an activity relevant to her goal, with consent, and record a useful baseline. Pain on movement describes her experience; it does not, on its own, identify the exact tissue generating pain.
Decision 2: respond to the request for imaging
The Clinical Care Standard recommends reserving imaging for findings suggesting specific or serious pathology, rather than using it routinely in an uncomplicated presentation. Discuss what an investigation could change, including the possibility of findings unrelated to the current symptoms.
A useful response to Maya would acknowledge her concern, explain what today’s assessment found and describe the proposed next step. For example: “I understand you want to know that moving is safe. Today’s assessment has not identified a reason for an urgent scan. We can agree on some manageable activity and review your progress, and I will explain which changes need earlier assessment.”
This is a sample explanation, not a script to repeat regardless of findings. “Never image back pain” would be an unsafe general rule. Reconsider investigation or referral when the history, examination or subsequent course changes the clinical question.
Decision 3: make the plan practical
Healthdirect advises keeping active, with modifications as needed, rather than extended bed rest for uncomplicated low back pain. Apply that principle to something Maya values: a short manageable walk and a plan for varying position during desk work. Agree a starting amount she can attempt and a way to judge the response; do not prescribe a generic exercise dose from the diagnosis alone.
Check understanding by asking her to describe the plan in her own words. If she still believes any discomfort means new damage, more exercise instructions will not resolve the misunderstanding. Discuss the concern without dismissing the pain. Consider what support is needed if fear or distress continues to restrict participation.
A treatment that temporarily eases symptoms may help participation, but the consultation should also leave her with a usable self-management plan. Avoid making ongoing passive treatment the only route to progress or promising that one posture, technique or exercise will fix every episode.
Compare plausible decisions
| Decision | Reasoning in Maya’s case |
|---|---|
| Arrange routine MRI before any activity | The assessment has not identified an indication that makes imaging the necessary first step. Her concern needs discussion, not an automatic investigation. |
| Recommend bed rest until all pain resolves | Postpones her functional goals and may reinforce her fear of movement. A manageable activity plan better addresses this presentation. |
| Agree activity goals, explain the findings and arrange review | Connects the current assessment with her concerns, function and a way to check whether the plan is helping. |
| Give reassurance without follow-up or safety advice | Leaves no clear route for reassessment if recovery differs from expectations or new symptoms appear. |
Decision 4: review function and revisit the assessment
Arrange follow-up based on her needs and clinical course. Compare meaningful activities with the baseline: how long she can manage desk tasks, the walk she completes and her confidence attempting usual movement. Record symptoms as well. A lower pain rating with no improvement in valued activity is only part of the picture.
If improvement is limited, find out what happened before repeating the same prescription. Was the plan understood, feasible and attempted? Did symptoms change? Were the initial assumptions reasonable? Depending on the reassessment, adjust the plan or involve another clinician. Review should produce a decision, not just another measurement.
New urinary retention, saddle sensory change or rapidly progressive leg weakness requires emergency assessment for possible serious neurological pathology. In this community example, stop routine treatment and arrange immediate emergency care; do not wait for the scheduled review. Healthdirect also advises calling 000 for back pain with loss of limb feeling or movement, or bladder or bowel control problems.
Use the scenario to test your reasoning
Write down which finding supports each step: no current imaging indication, a functional goal, a concern affecting participation and a clear review plan. Then change one element. How would a significant traumatic mechanism, progressive neurological signs or a different work demand change what you assess or do next?
Across other musculoskeletal topics, practise the same habit of justifying decisions with the case details. It helps distinguish a useful initial plan from an answer that merely names a diagnosis or lists treatments.
Questions people ask
- Does low back pain always need imaging before exercise?
- No. Imaging decisions depend on the assessment and whether findings suggest specific or serious pathology. Routine imaging is not the default for an uncomplicated presentation; new concerning features require reassessment.
- Why discuss beliefs and work goals in a musculoskeletal case?
- They help explain the effect of pain on participation and whether a proposed plan is practical. Addressing concerns does not mean the pain is imaginary or replace assessment for physical and serious causes.
- Is this low back pain example an official APC question?
- No. It is an original study example for practising initial assessment, communication and management decisions. It does not predict examination content or establish a treatment protocol for every patient.
