REHB1001 Chap.4 Focus of Reasoning and Hypothesis Categories
Focus of Reasoning and Hypothesis Categories
Topics 4 and 5 widen reasoning beyond diagnosis. This chapter sets out the seven foci of reasoning named in Topic 4, from diagnostic and psychosocial to procedural and prognostic, and the eight hypothesis categories of Topic 5, drawn as a non-hierarchical ring.
It covers problem classification by pathology, pain mechanism and source of symptoms, the five types of impairment, contributing factors, the six safety decisions and red flags, irritability, management versus treatment, and the determinants of prognosis. Worked examples fill the categories from one history and classify a shoulder problem without overclaiming the structure at fault.

Filling the hypothesis categories from one subjective examination
- +1Activity and participation: kneeling is limited and the garden role has stopped.
- +1Psychosocial: the belief that the joint is wearing out may drive avoidance.
- +1Precautions: unexplained weight loss is a warning sign that needs screening and possible referral.
- +1Contributing factors: sustained kneeling and gardening load may be maintaining the problem.
Key terms
- Hypothesis categories
- Eight broad, non-hierarchical categories of clinical judgement about a problem and a person.
- Irritability
- How easily symptoms are aggravated, whether activity can continue, and how long symptoms take to settle.
- Red flags
- Signs and symptoms that may point to serious, systemic or visceral disease.
- Nociplastic pain
- Pain arising from altered nociceptive processing in the central nervous system.
- Contributing factor
- A predisposing or associated factor behind the development or persistence of a problem.
- Collaborative reasoning
- Reasoning shared with the patient to choose care, also called shared decision making.
- Prognosis
- The therapist's informed hypothesis about the natural course of a problem and the time to change it.
- Watch and wait
- Proceeding cautiously with close monitoring instead of referring immediately.
Focus of Reasoning and Hypothesis Categories FAQ
How many hypothesis categories are there?
Eight. Topic 5 lists activity and participation, the psychosocial category, problem classification, impairments of function or structure, factors that contribute to the problem, precautions and contraindications, management or treatment, and prognosis. One Tutorial 3 heading says ten, but the list beneath it and the Topic 5 module both give eight, so revise the eight.
Do I have to consider every category after every question?
No. The script says that is unrealistic and that the framework does not set the order of the examination. It also warns against collecting information without thinking. The aim is to hold hypotheses in most categories by the end of the subjective examination, ready to test physically.
What makes a presentation highly irritable?
Symptoms that flare with little activity, stop the activity, and take a long time to settle. Topic 5 says high severity and irritability call for a limited examination, so you choose fewer tests, take them only to the onset of symptoms and recheck resting symptoms after each one.
What are the three main pain mechanisms in Topic 5?
Nociceptive pain, with or without inflammation; neuropathic pain; and nociplastic pain, which arises from altered processing of nociception in the central nervous system. The topic notes that sensitised presentations can give false positive findings on examination, so the dominant mechanism changes how cautiously you test and treat.
What decides a person's prognosis?
Topic 5 names the nature of the problem, its extent, its natural course, how well interventions work, and the person's ability and willingness to change. Clues include their beliefs and readiness, social and work barriers, the stage of healing, irritability, the length of the history and their general health.
What are the six safety decisions in the precautions category?
Whether to examine or refer immediately, whether to limit the examination, whether specific safety tests are needed, whether to treat or refer after examining, which interventions to avoid or approach with caution, and what dose or intensity is appropriate. Topic 5 introduces them with the reminder that safety is paramount.
Exam move
Learn the eight categories as a ring, not a list, and practise naming one hypothesis in each for every tutorial case. Pair the seven foci with a question each focus asks. Keep a short card of the serious pathologies and the six safety decisions, and rehearse the difference between interactive and collaborative reasoning aloud, since the sample viva asks for it.
When you revise red flags, say what you would ask, what answer would worry you, and whether you would refer at once or watch and wait.
