OMSB Physiotherapy common mistakes
OMSB Physiotherapy · Understand the traps and how to avoid them.
Committing to a single diagnosis (e.g., 'lumbar radiculopathy') from the vignette's headline symptom and then selecting management options that presuppose it, instead of working through a differential and choosing the safest next step.
Candidates pattern-match the most memorable feature of a stem (shooting leg pain, positive straight leg raise) and stop reasoning; the exam deliberately includes distractors that fit a competing diagnosis, and management questions reward the step that confirms or excludes before treating.
What to do instead
Before answering, write the two or three conditions the stem could represent and the one finding that separates them (e.g., dermatomal versus sclerotomal distribution, symptom behaviour with repeated movement, red-flag screen). Choose the option that is appropriate across the differential or that best discriminates between them.
Clearing a patient for cervical or lumbar mobilisation/manipulation without documenting a red-flag screen (recent trauma, night pain, unexplained weight loss, fever, progressive neurological deficit, bladder or bowel change, anticoagulation).
Practical training emphasises technique; candidates memorise handling skills and treat screening as a formality, and vignettes often bury a single red flag in an otherwise routine presentation.
What to do instead
Adopt a fixed pre-treatment checklist that you apply to every vignette: trauma, cancer history, infection signs, cauda equina symptoms, vascular risk, and coagulation status. If any is present, the correct answer is to defer, refer, or modify, not to proceed with manual therapy.
Answering neurological questions by naming the lesion level from a single sign rather than mapping the full pattern of weakness, tone, reflexes, and sensory loss to upper versus lower motor neuron and to a specific tract.
Candidates recall isolated facts (e.g., 'foot drop = L5') and apply them without integrating the examination; the exam tests whether you can distinguish peripheral from central causes and localise within the neuraxis.
What to do instead
For each neuro vignette, tabulate tone, reflex, plantar response, distribution of weakness, and sensory level before selecting. Practise classifying the same presentation as UMN versus LMN and note which single finding flips the classification.
Prescribing strengthening or gait progression for a neurological patient without addressing the actual limiting impairment, for example progressing resistance training in a patient whose gait limitation is spasticity, sensory loss, or fear of falling.
Exercise prescription is over-learned as 'progress load and repetitions', so candidates apply it mechanically; neuro rehabilitation questions reward impairment-based targeting and task-specific training.
What to do instead
State the primary impairment first, then match the intervention to it: task-specific gait retraining for gait, constraint or repetitive practice for upper limb, tone management strategies for spasticity. Justify why the alternative intervention does not address the identified impairment.
Interpreting arterial blood gases and chest auscultation in isolation, for example calling a low PaO2 'hypoxaemia due to pneumonia' without checking PaCO2, pH, bicarbonate, and the patient's work of breathing.
Candidates memorise normal values but not the stepwise interpretation sequence, and cardiopulmonary vignettes present several abnormal numbers at once.
What to do instead
Use a fixed sequence every time: oxygenation, then pH, then PaCO2 to identify respiratory versus metabolic direction, then compensation, then anion gap if metabolic. Only after that step link the pattern to the clinical scenario.
Choosing secretion clearance or breathing exercises for a deteriorating respiratory patient when the correct answer is to escalate (call for review, oxygen titration per target range, non-invasive support) rather than continue physiotherapy.
Candidates focus on which technique is 'best' and overlook that the safest option is sometimes to stop and escalate; deteriorating-patient vignettes are designed so that the most technical answer is wrong.
What to do instead
Before selecting any technique, check for deterioration criteria: rising respiratory rate, falling saturation despite therapy, increasing oxygen requirement, altered consciousness. If present, the answer is escalation and documentation, with physiotherapy resumed once stable.
Applying adult developmental milestones or adult exercise parameters to infants and children, for example expecting a 6-month-old to sit independently or prescribing adult resistance increments for a child.
Most training and clinical exposure is adult-focused, so candidates default to adult norms; paediatric questions test milestone timing and age-appropriate dosing.
What to do instead
Build a milestone table (head control, rolling, sitting, crawling, standing, walking) with age ranges and review it before the exam. For dosing, learn the principle of play-based, shorter sessions with lower absolute loads and reassessment of fatigue and response.
Skipping informed consent, capacity assessment, or confidentiality reasoning and choosing the clinically effective option when the vignette is actually testing an ethical or legal principle.
Candidates read ethics items as clinical items and pick the option that helps the patient most, missing that autonomy, best interests, and mandatory reporting override clinical enthusiasm.
What to do instead
Identify the question type first: if the stem mentions refusal, a minor, a third party, or a record request, it is an ethics item. Apply the sequence of capacity, informed consent, least restrictive option, confidentiality limits, and documentation, then choose accordingly.
Selecting an outcome measure or special test without checking its psychometric suitability for the population and purpose in the stem (e.g., using an acute pain scale for a chronic condition, or a screening test as a diagnostic confirmation).
Candidates recognise familiar test names and choose by familiarity rather than by whether the tool is validated for that population, setting, and decision.
What to do instead
For each outcome measure you revise, record the population it was validated in, whether it measures impairment, activity, or participation, and its responsiveness. In the exam, match the tool to the stated purpose: screening, diagnosis, or monitoring change.
Ignoring contraindications and precautions specific to the modality chosen, such as applying heat over an area of impaired sensation, or exercising a patient with unstable cardiac status or uncontrolled hypertension.
Candidates focus on the indication and the technique, and precautions are learned as a list rather than as a decision gate; vignettes often embed one contraindication among several plausible indications.
What to do instead
Before finalising any modality answer, run a rapid contraindication check for that modality (sensation, circulation, malignancy, infection, implanted devices, cardiac stability, pregnancy). If a contraindication is present, select the modification or alternative modality.
