1.1 Patient Health History & Interviewing

Patient Health History & Clinical Interviewing

Clinical Core: The subjective health history interview is the cornerstone of clinical reasoning in registered massage therapy. Most safety contraindications, red flags, and working hypotheses are identified through structured patient inquiry before physical palpation or orthopedic testing begins.

1. Professional & Legal Foundations of Health History Collection

In Canadian regulated healthcare environments, obtaining and maintaining a comprehensive health history is both a standard of practice and a legal prerequisite for lawful, informed consent. Regulatory colleges (such as the College of Complementary Health Professionals of British Columbia [CCHPBC] and the College of Massage Therapists of Ontario [CMTO]) mandate that a Registered Massage Therapist (RMT) must collect a comprehensive baseline health history before initiating any physical assessment or manual treatment.

Core Purposes of the Health History

• Safety Screening: Identifying absolute contraindications, relative contraindications, local red flags, and pharmacotherapeutic interactions that dictate clinical modifications.
• Baseline Functional Profiling: Documenting the patient's pre-injury and current capacities in activities of daily living (ADLs), occupational tasks, and recreational pursuits.
• Diagnostic Hypothesis Generation: Differentiating between musculoskeletal (mechanical) disorders, neurogenic impairments, and non-mechanical or visceral referral patterns.
• Medicolegal Baseline: Formulating a contemporaneous, defensible clinical record that documents pre-existing pathologies, prior surgeries, implanted hardware, and informed consent discussions.

Under provincial healthcare legislation, the health history is a living document. While a full written intake questionnaire is completed at the initial visit, the RMT must verbally verify and update the patient's health status at every subsequent appointment, noting any new medications, recent trauma, or changes in systemic symptoms.

2. Therapeutic Rapport & Patient-Centered Interviewing

Collecting subjective clinical data requires communication strategies that establish trust, safety, and mutual understanding. Patients frequently present in acute or persistent pain, experiencing heightened autonomic arousal, anxiety, or frustration with prior healthcare encounters.

Environmental & Interpersonal Considerations

• Privacy and Confidentiality: Conduct the interview in a quiet, closed treatment room where conversations cannot be overheard, adhering to provincial health privacy legislation (e.g., PIPA, PHIPA).
• Non-Verbal Communication: Maintain open, non-defensive posture, sit at equal eye level without physical barriers (such as a desk or elevated treatment table separating practitioner and patient), and maintain culturally appropriate eye contact.
• Trauma-Informed Practice: Recognize that physical pain and touch therapy can elicit vulnerability or trauma responses. Emphasize patient autonomy, clarify that the patient retains the right to stop or modify treatment at any moment, and explain the clinical rationale behind sensitive questions.

The Inverted Pyramid Interviewing Funnel

The effective clinical interview follows an inverted pyramid communication model:

1. Broad Open-Ended Inquiry: Begin by allowing the patient to articulate their story in their own words without interruption (e.g., "What brings you in today?" or "Describe how this shoulder discomfort is impacting your daily routine."). Research demonstrates that allowing uninterrupted initial speaking (typically lasting 60 to 90 seconds) dramatically improves diagnostic accuracy and therapeutic rapport.
2. Focused Probing Questions: Narrow the inquiry to specific variables (e.g., "You mentioned the pain travels down your arm; does it reach past your elbow into your hand?").
3. Closed Clarifying Questions: Obtain exact, unambiguous data points (e.g., "Did the swelling appear immediately within one hour of the twist, or the following morning?" or "Are you currently taking any prescription blood thinners?").
4. Reflective Summarizing: Paraphrase the patient's account back to them (e.g., "What I hear is that your lower back pain began three weeks ago after lifting heavy boxes, worsens after sitting for more than 20 minutes, and radiates into your right buttock without numbness or weakness. Is that accurate?"). This validates the patient and identifies discrepancies early.

3. Structured Pain & Symptom Assessment Frameworks

To ensure no critical diagnostic parameter is overlooked, RMTs utilize structured symptom inquiry frameworks. Two acronyms are widely taught: OPQRST (common in multidisciplinary and emergency triage) and LOTTAARP (a pain-history mnemonic used in many Canadian massage therapy programs). Either is acceptable; what matters is that every dimension of the symptom is explored.

The OPQRST Framework Breakdown

• O — Onset:
  • Mechanism of Injury (MOI): Traumatic (macro-trauma, e.g., motor vehicle accident, direct blow, fall) versus insidious (micro-trauma, repetitive strain, postural fatigue).
  • Timeline: Tissue-healing stage is usually described as acute (roughly the first 72 hours), subacute (about 72 hours to 3–6 weeks), and chronic or remodelling (beyond about 6 weeks). Separately, pain lasting longer than 3 months is classified as chronic pain, whatever the tissue stage.
• P — Provocation & Palliation:
  • What specific motions, sustained postures, loads, or times of day aggravate the symptoms? (e.g., spinal flexion, deep breathing, coughing/sneezing [Valsalva]).
  • What relieves the pain? (e.g., rest, heat, ice, recumbency, gentle walking, over-the-counter NSAIDs).
• Q — Quality of Pain:
  • Precise sensory descriptors provide immediate clues to the anatomical tissue involved.
• R — Region & Radiation:
  • Focal point of maximal pain; dermatomal radiation (nerve root compression), peripheral nerve distribution, sclerotomal referral (deep somatic structures), or visceral referral.
• S — Severity:
  • Quantified via validated clinical scales: Numeric Rating Scale (NRS 0–10) or Visual Analogue Scale (VAS) at rest, at worst, and at best.
• T — Timing:
  • Diurnal variation: Morning stiffness lasting >30 minutes indicates inflammatory arthritis (e.g., rheumatoid arthritis, ankylosing spondylitis); morning stiffness easing within 10–15 minutes suggests mechanical osteoarthritis; pain progressively worsening toward the end of the day indicates postural fatigue or spinal disc loading; constant unyielding night pain suggests serious red flag pathology.

The LOTTAARP Framework Breakdown

The LOTTAARP mnemonic expands symptom inquiry by prioritizing functional limitations and patient goals:

4. Tissue Differentiation Through Pain Quality Analysis

Analyzing the specific qualitative descriptors provided by the patient during the subjective interview provides critical preliminary differentiation between contractile, inert, neurological, and systemic tissue sources:

• Nerve (Root or Trunk): Described as sharp, shooting, lancinating, electric, burning, or accompanied by paresthesia (pins and needles) and numbness. Follows distinct dermatomal or peripheral nerve distributions.
• Muscle (Contractile Tissue): Described as dull, aching, cramping, stiff, or sore. Typically localized to the muscle belly or myotendinous junction, aggravated by active contraction and passive elongation, and tender to direct compressive palpation.
• Tendon / Tenosynovium: Described as sharp with active loaded movement, transitioning to a dull, persistent ache after activity. Often exhibits morning stiffness that warms up with gentle unloaded movement, only to worsen with repetitive loading.
• Ligament / Joint Capsule (Inert Tissue): Described as deep, dull ache at rest, turning sharp, catching, or unstable at end-range joint motion. Often accompanied by feelings of joint "giving way" or mechanical locking.
• Bone / Periosteum: Described as deep, piercing, boring, exquisitely localized, and unyielding. Pain is often severe, persistent, and uninfluenced by typical muscular unloading.
• Visceral Referral: Described as deep, poorly localized, diffuse, cramping, colicky, or gnawing. Completely unaffected by spinal or joint movement, unresponsive to rest or mechanical unloading, and frequently accompanied by autonomic signs (nausea, diaphoresis, pallor).

5. Comprehensive Medical History & Systems Review

A thorough subjective assessment extends far beyond the chief complaint. The RMT must systematically investigate four core medical domains:

Past Medical History (PMHx) & Surgical Review

• Traumatic Events: Motor vehicle collisions (whiplash-associated disorders, occult fractures, concussions), sports injuries, falls, and dislocations. Past sprains or fractures compromise structural stability and proprioception, predisposing adjacent joints to compensatory hypermobility or hypomobility.
• Surgical Procedures: Record exact dates, surgical techniques (arthroscopic vs. open repair), and presence of internal fixation hardware (screws, plates, pins, artificial joints). Hardware alters regional compliance and contraindicates aggressive joint mobilizations or high-velocity techniques over the site.
• Scar Tissue Evaluation: Surgical incisions and traumatic scars can form dense fascial adhesions, entrap cutaneous nerves, restrict range of motion, and disrupt myofascial force transmission.

Systems Review (Screening for Comorbidities)

• Cardiovascular: Hypertension, atherosclerosis, history of transient ischemic attacks (TIAs), stroke, angina, heart failure, and peripheral vascular disease. Directly influences positioning (avoiding prolonged prone or flat supine), pressure depth, and hydrotherapy applications.
• Respiratory: Asthma, chronic obstructive pulmonary disease (COPD), emphysema. Patients may experience dyspnea when lying flat, requiring semi-Fowler or side-lying treatment positions.
• Neurological: Epilepsy, multiple sclerosis, Parkinson's disease, peripheral neuropathies. Requires careful monitoring of sensory feedback and autonomic reactivity.
• Endocrine & Metabolic: Diabetes mellitus (neuropathy, microvascular disease, fragile skin, hypoglycemia risk), thyroid disease (temperature regulation abnormalities, osteoporosis risk).
• Rheumatological & Connective Tissue: Rheumatoid arthritis, ankylosing spondylitis, systemic lupus erythematosus, Ehlers-Danlos syndrome. Strict precautions regarding joint mobilizations, tissue fragility, and inflammatory flare-ups.

Medication & Supplement Cross-Examination

The RMT must record all prescription drugs, over-the-counter medications, and herbal supplements. Medications alter physiological responses to manual therapy—blunting pain feedback, promoting excessive bruising, altering muscle tone, or precipitating postural hypotension.

6. Clinical Reasoning: Case Scenario Analysis

Clinical Vignette

Patient Profile: A 46-year-old female accountant presents with a chief complaint of "constant right shoulder and upper back pain" that has persisted for four weeks.

Interview Findings:

• Onset: Insidious; no known trauma or sporting activity.
• LOTTAARP Breakdown:
  • Location: Right supraspinous fossa radiating toward the right inferior scapular angle and right subcostal region.
  • Quality: Deep, gnawing, burning ache.
  • Timing: Fluctuates throughout the day; notably intensifies approximately 45 to 60 minutes after evening meals.
  • Aggravating/Relieving: Active and passive shoulder abduction, cervical rotation, and thoracic flexion cause no change in pain severity. Rest, heat packs, and ibuprofen provide minimal relief.
• Medical History: Reports a history of gallstones diagnosed two years prior; currently taking no prescription medications.

Clinical Reasoning Process

1. Mechanical vs. Non-Mechanical Triage: True musculoskeletal conditions of the shoulder (e.g., supraspinatus tendinopathy, subacromial bursitis, cervical radiculopathy) exhibit distinct mechanical behavior—they are provoked by specific joint motions (such as arm abduction between 60° and 120° in a painful arc) or cervical compression tests (Spurling's).
2. Pattern Recognition: In this case, active shoulder and cervical ranges of motion are completely pain-free and unprovoked. The pain correlates temporally with digestion (especially postprandial fat consumption) and refers to the right inferior scapular angle.
3. Neuroanatomical Referral: Biliary colic / gallbladder pathology refers pain to the right shoulder and inferior scapular margin via sensory afferents traveling along the phrenic nerve (C3–C5 dermatomal overlap) and thoracic sympathetic splanchnic pathways (T5–T9).
4. Therapeutic Action: The RMT recognizes a non-mechanical visceral referral pattern. The therapist withholds vigorous manual intervention to the right shoulder, avoids aggravating abdominal palpation, explains the non-musculoskeletal nature of the symptoms to the patient, and coordinates an urgent referral to her primary care physician for abdominal diagnostic imaging.
