Study Notes

Low Back Pain

Common Causes and Risk Factors: Discogenic pain, ankylosing spondylitis, aging, obesity, smoking, vibrations, excessive axial loads, genetic susceptibility.
Chronic Back Pain Progression (Pathophysiology): Damage to discs and vertebral endplates leads to new blood vessel growth and sinuvertebral nerve ingrowth into the disc, causing inflammation. Abnormal disc stresses and normal fluid loss cause dehydration and degeneration. This uneven loading leads to annular fibre tears, microfractures in endplates, and structural changes in ligaments and facets. The nucleus pulposus releases inflammatory chemicals, creating a cycle of inflammation that recruits more blood vessels.
Holistic Treatment Planning Beyond Manual Therapy and Exercise: Medical treatments include corticosteroid injections, radiofrequency treatments (potential for nerve destruction), nucleoplasty (RF to shrink nucleus pulposus, but may grow back), discectomy, and fusion. MRI is often reserved for specific cases like substantial trauma, certain age groups, loss of function, or other serious symptoms.

Discogenic Low Back Pain

Definition: Chronic low back pain caused by disc damage involving the development of new blood vessels and sinuvertebral nerves burrowing into the back of the disc, causing inflammation (not a herniation). An annular fiber tear leads to loss of disc material (not a herniation — fibres intact).
Pathophysiology: Abnormal stresses and normal loss of fluid in the disc leading to dehydration and degeneration. This uneven loading leads to tears in annular fibres, microfractures in the end plates of vertebrae, and structural changes to ligaments and facets. Chemicals released from the nucleus pulposus cause an inflammatory response, drawing new blood vessels and nerves into the damaged disc.
Risk Factors: Age, obesity, smoking, vibrations from transportation, excessive axial loads, and genetic susceptibility.
Symptoms: Pain in the back (not legs) aggravated by lifting, bending, sitting/standing, or Valsalva maneuvers (coughing, sneezing). Symptoms are often worse the next day after injury.
Diagnosis: Crucial to establish a thorough clinical history. Local tenderness, muscular hypertonicity, reduced range of motion, and abnormal movement patterns (e.g., a "catch" during movement) are common. Valsalva maneuver is positive for local pain but not leg pain.
Imaging: An MRI is often not directly correlated to symptoms and generally recommended only in specific cases, which include substantial trauma or trauma in patients ≥50 years old, or other serious symptoms or conditions.

Cauda Equina Syndrome

Cause: Compression of the cauda equina caused by tumors, trauma/spondylolisthesis, infections, ankylosing spondylitis, lumbar central stenosis, or disc herniation.
Prevalence: Only 2% of lumbar disc patients are affected.
Symptoms: Saddle anesthesia (loss of sensation around the buttocks and groin), bowel and bladder disturbances. These disturbances can include difficulty with initiating or stopping urination (leading to retention and overflow incontinence), incontinence, or constipation. Unilateral or bilateral sciatica, low back pain, leg weakness, and sensory deficits are also possible.
Differential Diagnosis: The key to suspecting Cauda Equina Syndrome is to ask if there is a difference in sensation when wiping after bowel movement.
Signs: Sensory (dermatomal changes), muscle (myotomal weakness), and reflex (hypo/areflexia) deficiencies.
Treatment: Immediate and urgent referral to A&E – failure to recognize these signs can result in permanent incontinence.

Benign Hypermobility Joint Syndrome

Cause: A connective tissue disorder involving generalized joint laxity.
Symptoms: Joint pain in multiple areas – neck, shoulders, low back, hips, knees, and ankles. Symptoms could include easy bruising, subluxation, dislocation, meniscal tears, and hiatus hernia (a condition when part of the stomach protrudes through the diaphragm).
Prevalence: Decreases with age, higher frequency in females.
Diagnosis: Uses Brighton criteria (questionnaire) and Beighton score to assess degree of joint laxity.
Additional Criteria: Back pain of at least 3 months; dislocation or subluxation in 3 or more joints or 1 joint more than 3 times; and ≥3 instances of sports-related injuries.
Diagnostic Criteria: Beighton score ≥4; arthralgia (joint pain) in 4+ joints for ≥3 months; back pain ≥3 months; 3+ previous sports injuries.

Headaches and Neck Pain

Cervicogenic Headache: Headache originating from a cervical spine structure (periosteum, ligaments, osseous, nerve irritation, or reflex muscle spasm).
Red Flags (Intracranial Hemorrhage): A sudden onset of neurological dysfunction requiring immediate referral.
Canadian C-spine Rule: A clinical decision-making tool to determine the need for imaging in potential c-spine injuries in alert, stable patients ≥16 years old.

Cerebrovascular Disease

General: Any condition disrupting blood supply to the brain. 80% are ischemic, while the other 20% are hemorrhagic.
Categories: Occlusive CVD (stroke), TIA, hemorrhage, vascular malformations (aneurysms, AVM). Associated Conditions: Diabetes, vascular diseases, hematocrit issues, and collagen diseases (like Marfans).
Ischemic Stroke: Neuron death due to oxygen deprivation. ATP pump failure leads to depolarization, neurotransmitter release, calcium influx, and protease/lipase activation, causing further damage.
Hemorrhagic Stroke: Slow blood leaks (hematoma) lead to toxin release (heme) causing free radical formation and cell damage. Rapid bleeds (arteries) lead to immediate neuron loss and oedema (swelling), which further occludes blood flow.
Risk Factors: Hypertension (major factor in 90% of stroke cases), atrial fibrillation, history of TIA, stroke, aneurysm, diabetes, and vascular/hematocrit diseases. Family history slightly increases risk.
Transient Ischemic Attack (TIA): Sudden, focal neurological symptoms resolving within 24 hours—often within 30 minutes. Possible causes are vasospasm, embolus, or thrombosis of a narrowed vessel. TIA is a precursor to infarction, so requiring urgent referral.

Peripheral Neuropathy

Mechanisms (B12 deficiency, diabetic neuropathy): B12 deficiency leads to axonal damage. Diabetic neuropathy involves demyelination and ischemia. Sensory ataxia is a gait pattern.
Differential Diagnosis (Guillain-Barré): Guillain-Barré involves progressive, ascending muscle weakness, occurring 2-4 weeks after a minor illness (distinguishes it from other conditions).
Physical Exam Tests: Vibration testing, reflex testing, proprioception testing.
Peripheral Arterial Disease (PAD): Hallmark is intermittent claudication (leg pain during exercise).
Motor Neuron Disease (MND): Progressive, painless, asymmetric weakness spreading through the body.

Temporal Arteritis

Definition: Systemic inflammatory vasculitis of unknown cause, particularly affecting the superficial temporal arteries.
Symptoms: Bilateral, constant, progressive, pulsatile headache; tender scalp; worse at night; painful jaw muscles; associated with other conditions (e.g., polymyalgia rheumatica). TIA possible, visual acuity loss and blindness are potential red flags.
Diagnosis: Elevated ESR/CRP levels, temporal artery biopsy (confirmation).
Management: Urgent referral.

Intracranial Hematoma

Traumatic Brain Injury (TBI): Often from head trauma; types include epidural, subdural, and intracerebral. Common in TBI: loss of consciousness, headache, nausea/vomiting, altered mental status, unequal pupils/blurred vision, seizures, and focal neurological deficits.
Aneurysmal Rupture and Subarachnoid Hemorrhage (SAH): Rupture of a cerebral aneurysm or AVM leading to bleeding into the subarachnoid space; causes sudden, severe "thunderclap" headache, neck stiffness, photophobia, altered mental status/coma.
Neuro Tests (Both types): GCS, CT scan (immediate detection), MRI (subacute/chronic). Treatment for both may include emergency surgical evacuation, ICP reduction, and observation.

Canadian C-Spine Rule

Inclusion: Alert, stable patients ≥16 with neck pain or suspected cervical spine injury after trauma.
Exclusion: Non-traumatic injuries, known vertebral disease, penetrating trauma, pregnancy.
High-Risk Criteria (Mandates Imaging): Age ≥65; dangerous mechanism of injury (falls from height, axial load trauma, high-speed collisions); presence of paresthesias.
Low-Risk Criteria (Allows ROM assessment): Simple rear-end collisions (without specific factors); sitting position in ED; ambulatory since injury; delayed onset of pain; and absence of midline cervical tenderness.
Active Range of Motion: Can actively rotate neck 45 degrees bilaterally? If no, imaging needed.

Seizures

Epilepsy: Brief changes in behavior due to disordered, rhythmic neural firing. Risk factors include idiopathic causes, congenital defects, genetic factors, drugs, infections, and vascular conditions.
Seizure Types: Partial (simple/complex) and generalized (absence/grand mal).
Symptoms: Consciousness change, clonic movements, tonic positions, sensory changes—often indicative of the origin point in the cortex (temporal, parietal, occipital).
Treatment: Anticonvulsants to reduce excitability (e.g., phenytoin, carbamazepine), enhance GABAergic inhibition (e.g., phenobarbital), or block GABA reuptake.

Memory Changes and Tremors

Types of Memory: Short term, procedural, working memory.
Types of Tremors: Resting, action, endpoint. Tremors classified by when the tremor is apparent: at rest, with movement, or at the end of a movement (endpoint).

Mild Cognitive Impairment (MCI)

Definition: A cognitive syndrome where cognitive ability is not equal to same-aged peers, but without dementia or ADL impairment.

Dementia

Definition: Progressive deterioration of intellect, behavior, and personality impairing ADLs.
Types: Alzheimer's disease (60%), vascular dementias (20%), frontotemporal dementia, dementia with Lewy bodies.
Risk Factors: Age, family history, hypertension, metabolic syndrome/diabetes, vascular events, smoking are common risk factors for dementia, and may be potentially changeable (modifiable) with lifestyle changes.
Symptoms: Cognitive, emotional/behavioral, and ADL deficits. These deficits are progressive over the decades (although vascular dementia may develop faster).

Alzheimer's Disease

Symptoms: Memory impairment (cardinal sign - rapid forgetting/poor delayed memory recall), disorientation in time/place, visuospatial difficulties, procedural memory impairment ("how to do"), language impairment, depression, aggression, agitation, and wandering.

Tremors

Essential Tremor: Most common, often familial. Slowly progressive postural/kinetic tremor (often in upper limbs), worsening with emotion, hunger, fatigue, or temperature changes.
Resting Tremor: Involuntary, rhythmic oscillations at rest; most common in Parkinson's disease and related syndromes.
Endpoint Tremor: Tremor worsens as the target is approached; associated with cerebellar dysfunction causing oscillations due to errors in movement calculation and correction.

Peripheral Nerve Entrapments (Mononeuropathies)

Median Nerve: Most common location is the wrist (Carpal Tunnel). Causes include repetitive strain injury from typing, pregnancy, or hypothyroidism. Compression might occur.
Ulnar Nerve: At the elbow (Cubital Tunnel), typically from prolonged elbow flexion or compression.
Radial Nerve: Entrapment at the elbow; radial tunnel syndrome (controversial), tennis elbow (lateral epicondylitis)-like presentation.
Posterior Interosseous Nerve (PIN): Entrapment in the supinator muscle.
Sciatic Nerve: Overuse, SIJ dysfunction, piriformis syndrome, gluteus medius/minimus entrapment, hamstring attachments.
Lateral Cutaneous Nerve: "Meralgia parasthetica," entrapment at the inguinal ligament.
Obturator Nerve: Entrapment in the fascia.
Peroneal Nerve: May be entrapped at fibular head, due to injuries (e.g., to the distal knee region), cysts around the knee, or compartment syndrome.
Tibial Nerve: Commonly from ankle/tibia fxs or dislocations; less often in the tarsal tunnel.

General Clinical Management

Seizures: Time duration, multiple seizures without recovery, breathing difficulty require ambulance.
Memory Changes: Types (short-term, long-term, working), differentiating factors.
Tremors: Differentiating various tremor types (resting, postural, kinetic, etc.) by symptoms and patterns.
