Q4 Notes

Neuromuscular Reflex

  • Neuromuscular Reflex: Control & coordinate skeletal muscle contraction

  • Types:

    • Simple Reflex Arc

    • Complex Neuronal Pathways

  • Reflex Arc: Simple neuronal pathways for reflexes; providing a predictable motor outcomd for a specific sensory stimulation

  • Sensory Receptors

  • Mechonoreceptors: Sensitive to mehcanical changes

  • Proprioception: Sense & awareness of where body parts are in space

  • Muscle Spindle: Receptor in muscle belly which detects length/stretch of muscle fibres; signals a reflextive contraction

  • Golgi Tendon Organ: Receptor in tendon detecting contraction/tension in the muscle; signals a reflexieve relaxation

  • Reciproal Inhibition: Reflexthat coordinates effecort between agonist & antagonist

    • Muscles recieve signals: Agonist contracts while antagonist is inhibited.

    • Can be used to allieviate hypertonicity

  • For Movement ro Occur:

    • Agonist is signaled to contract from nervous system

    • Antagonist release is by nervous system

  • Helps the cramp relax slightly before stretching the muscle fibers.

  • Isometric contraction of the antagonist sends a relaxation signal to the cramping muscle.

  • Reciprocal inhibition can be used before soft tissue work to engage neck flexors or opposite-side lateral flexors.

  • Stretch Reflex & Gama Gain

  • Stretch Reflex: Reflexive contraction of a muscle after it is stretched due to stimulation of muscle spindle

  • 2 Portions:

    • Alpha Loop

      • Alpha Sensory Neuron: Looped around muscle spindles & detects stretch of fibres

      • Alpha Motor Neuron: Innervates extrafusal fbres to create tension in response to the stretch

      • Mediates the Stretch Reflex

    • Gamma Loop

      • Gamma Sensory Neuron: Attached at ends of spindle

      • Gamma Motor Neuron: Innervates intrafusal fibres

      • Regulates sensitivity of the muscle spindle by adjusting the length & tension of intrafusal fibres

      • Stimulates alpha sensory neuron

  • Gamma Gain

    • Increased tension in intrafusal fibers heightens muscle spindle sensitivity to the rate of lengthening.

    • Spindle sends signals to the spinal cord based on how quickly the muscle is lengthening.

    • A fast stretch triggers a strong, immediate protective contraction.

  • Characteristics of Tender Points

    • May not be palpable.

    • Hypersensitive to mechanical pressure.

    • No referred pain; often silent until compressed.

    • Gamma gain can trigger a false stretch reflex.

    • Muscle held in a shortened position may suddenly contract concentrically when quickly lengthened.

    • Reposition of the muscle may desensitize & reset

      • Strain-Counter Strain

      • Positional Release

      • Functional Technique

      • Tender Point Release

  • Characteristics of Trigger Points

    • Palpable nodule in a taut muscle band.

    • Hypersensitive to pressure; reproduces pain in a predictable pattern.

    • Pain linked to chemical irritation at motor end plates, not neurological signals

  • Cause of Trigger Points (TrPs)

    • Muscle overload, injury, or underuse disrupts motor end plate function and increases acetylcholine release.

    • “Calcium spill” from sarcoplasmic reticulum causes actin-myosin binding.

    • Sarcomeres shorten, forming a contraction knot.

    • Sustained contraction depletes ATP, reducing blood flow and energy.

    • Leads to metabolic crisis, muscle fatigue, low-grade inflammation, and pain

Fascial System

        • Diaphragm – separates thoracic/abdominopelvic cavities

        • Pelvic diaphragm – supports pelvic organs

  • Mechanial Properties of Fascia

  • Viscoelasticity

    • Fascia extends and rebounds (not stretches and recoils).

    • Exercise increases fibroblast activity → more tropocollagen.

    • Treatment frequency/duration may matter more than session length.

    • ROM (range of motion) improves after exercise or massage.

  • Collagen

    • Made of tropocollagen protein bundles.

    • Structure:

      • Tropocollagen → Collagen fibrils → Collagen fibers

    • Collagen doesn't stretch but unwinds slowly under tension.

    • Rebounds to original shape when tension is gone.

  • Thixotropy

Hydrotherapy

  • The Skin - Access Organ for Circulation

    • Nerves: Sensory info + reflex responses

    • Blood Vessels: Exchange nutrients/waste

    • Lymphatics: Immune support + waste removal

    • Circulatory System:

      • Closed system

      • Change in one area affects circulation throughout the body

  • Six Ways to Manipulate Circulation

  • Direct Method

    • Happens in all applications

    • Immediate effect on superficial tissues

    • HEAT:

      • Dilates superficial blood vessels

    • COLD:

      • Constricts superficial blood vessels

  • Alternate Method (Hot + Cold)

    • Apply hot and cold in sequence

    • Types:

      • Cold alone (prolonged)

      • Heat followed by alternating hot/cold

    • Effects:

      • Direct local effect

      • Stimulates nervous system (ANS)

      • Hot before cold = stronger ANS response due to temp contrast

      • Decongests blood/lymph

      • Pain relief (analgesic)

      • One of the most powerful methods

  • Derivation & Retrostasis

    HEAT – Derivation

    • Blood/lymph flow toward heat

    • Brings oxygen/nutrients

    • Draws blood away from congested areas

    • E.g. congested headache → hot foot bath

    COLD – Retrostasis

    • Blood/lymph flow away from cold

    • E.g. congested headache → cold pack on neck

    • Affects distant (not local) areas

Collateral Circulation

  • Local application of heat/cold over a superficial artery

  • Alters flow in deeper artery from the same arterial trunk

  • Still uses derivation (heat) and retrostasis (cold) principles

  • Effects:

    • COLD → Constricts superficial artery
      → Increases flow through deeper artery (retrostasis)

    • HEAT → Dilates superficial artery
      → Decreases flow through deeper artery (derivation)

  • Arterial Trunk

    • Influences all distal branches of the trunk

    • Useful when local application is contraindicated

    • HEAT to femoral artery
      → Dilates vessels in the leg
      E.g. Diabetic leg ulcer – heat to femoral artery increases circulation without raising local metabolic stress

    • COLD to femoral artery
      → Constricts flow to leg
      E.g. Foot injury – ice to femoral artery reduces bleeding
      → Combine with pressure for stronger hemostasis

  • Spinal Cord Reflex

    • Uses dermatomes or reflex pathways to affect distant organs

    • Can treat opposite side if direct treatment isn’t possible

      • E.g. One hand in a cast → treat the other

    • Guidelines for Reflex Reactions

      • Smaller area of application → more reflexive effect

        • E.g. Ice on inner thigh → affects uterus

      • Larger area of application → more direct/local effect

        • E.g. Full hot foot bath → draws blood (derivation)

      • More extreme temperature → stronger reflex + local effect

        • Very cold hand = local + brain response

      • Closer to target organ → stronger reflex effect

        • Cold to chest → affects heart directly

        • Hot foot bath → more derivative than reflexive

Degenerative Disc Disease

General Patogenesis

  • Loss of vertebral disc height (normal with aging)

  • Intervertebral discs undergo wear and tear

  • Most affected areas: Lumbar and Cervical spine

    • Especially L4/L5 and L5/S1

  • Bulging and tears in annulus fibrosus

  • Alignment changes in facet joints

  • Formation of osteophytes (bone spurs)

Thinning Disc Changes

  • Nucleus pulposus changes from hydrophilic gel → fibrous (dries out)

  • Disc flattens → disc space narrows

  • Bulging/tearing triggers pain via nerve root branches

Pain Presentation

  • Pain may come from:

    • Disc

    • Facet joints

  • Causes:

    • Localized back pain

    • Referred pain to:

      • Buttocks

      • Legs (radiating low back pain)

Description of Degenrative Disc Disease

  • Narrowing of intervertebral foramen due to disc compression

  • Less space for nerve roots

  • DDD tends to occur earlier in cervical spine

Age-Related Disc Changes

  • 30s: Facet joint degeneration begins (increased stress)

  • Possible:

    • Synovitis (synovial membrane inflammation)

    • Joint effusion (swelling)

  • 40s: Osteophyte formation (limits motion)

  • 40s–50s:

    • Discs still absorb water

    • Nucleus becomes increasingly fibrous

  • Two types:

    • Acute Compartment Syndrome – medical emergency.

    • Chronic Compartment Syndrome – typically exercise-induced and less severe.

  • Acute: Anyone with traumatic injuries (common in young adults or athletes).

  • Chronic: Common in athletes, especially runners or those doing repetitive leg activity.

  • Out of proportion pain to the actual injury

  • Tight and burning

  • Hot to touch

  • Pain, cramping, weakness

  • Acute:

    • Fractures

    • Crush injuries

    • Burns

    • Snake/insect bites

    • Complications from surgery

  • Chronic:

    • Repetitive stress or athletic activity

    • Poor footwear or biomechanics

    • Muscle hypertrophy without sufficient fascial expansion

Dupuytren Contracture (Palmar Fasciitis)

  • Idiopathic thickening and shortening of the palmar fascia.

  • Leads to progressive loss of finger extension.

  • Causes fingers (commonly the ring and little fingers) to bend permanently toward the palm.

  • Proliferation Phase

    • Myofibroblasts multiply

    • Nodule forms at the base of the ring finger (palmar side)

  • Involutional Phase

    • Cord of tissue develops distally toward the PIP joints

  • Residual Phase

    • Cord tightens

    • Finger(s) bend permanently (flexion contracture)

  • Middle-aged to older white men

  • Of Northern European descent

  • Mildly tender or painless lump near the base of the ring finger

  • Palpable cord in the palm

  • Inability to fully straighten one or more fingers

  • Range from mild contracture to severe finger deformity

  • In very severe cases:

    • Compression of nerves and blood vessels

    • Hand function can be significantly impaired

  • Repetitive physical labor (especially with vibration)

  • Smoking

  • Alcohol use

  • Diabetes (Type 1 and 2)

  • Genetic predisposition

Ganglion Cysts

  • Small connective tissue pouches filled with viscous fluid that grow on joint capsules

  • Related to degeneration of fascia

  • Women > Men

  • Children & Young Adults

  • Small or Large Soft Lesion

  • Gradual or sudden onset

Bursitis

  • Bursae: Small synovial fluid-filled sacs that reduce friction between tendons and bones.

  • Bursitis: Inflammation of a bursa.

    • Caused by irritation, leading to cell proliferation and excess fluid.

    • Results in pain, swelling, and limited range of motion (ROM).

  • Housemaid’s Knee – Prepatellar bursa

  • Student’s Elbow – Olecranon bursa

  • Weaver’s Bottom – Ischial bursa

  • Trochanteric Bursitis – Lateral hip

  • Subacromial Bursitis – Shoulder

  • Calcaneal Bursitis – Heel

  • Septic Bursitis – Infection in the bursa (commonly superficial ones like elbow or knee)

  • Physically active individuals

  • People with physically demanding jobs (e.g. kneeling, lifting heavy loads)

  • Older adults (degenerative changes)

  • Those with inflammatory conditions

  • Pain with active (AROM) and passive (PROM) movement

  • Limited ROM due to muscle splinting (protective contraction)

  • Localized swelling and heat (especially in septic bursitis)

  • Pain increases with joint use or pressure

  • Repetitive stress or overuse

  • Occupations requiring:

    • Kneeling (e.g. floor layers, cleaners)

    • Carrying heavy objects

  • Pre-existing inflammatory conditions:

    • Rheumatoid arthritis

    • Gout

    • Tendon injuries

  • Direct trauma or prolonged pressure on joints

Illiotibial Band Syndrome

  • Inflammation & pain where ITB crosses lateral femoral condyle (friction)

  • Positive Noble’s Test

  • High-Activity

  • Those with issues in Gait

  • Ache, burning, or sharp pain

  • Local pain to lateral knee or radiation up lateral thight

Pes Planus (Flat Feet)

  • Loss of medial, lateral, and transverse arches

  • Often lacks spring, flexibility, and shock absorption

  • Young Children

  • Visible absence of arch when standing

  • May cause pain if associated with abnormal bone structure

  • Congenital deformities (bone shape, ligament strength)

  • Foot trauma (esp. to calcaneus or talus)

  • Malunion fractures

  • Unsupportive footwear

  • Muscle imbalance: deep flexors, evertors, weak ligaments

Pes Cavus (Caved Feet)

  • Overly high and rigid arch

  • Arch does not flatten with each step (reduced shock absorption)

  • Associated with Neuormuscular Disorders

  • Rigid, high arch with lateral foot pain

  • Extensive callusing

  • Ankle instability

  • Same as Above

Plantar Fascititis

  • Pain at the plantar fascia (bottom of foot)

  • Likely due to degeneration (not inflammation) → correctly called plantar fasciosis

  • Breakdown of collagen fibers in fascia

  • Women > Men

Classic pain pattern:

  • Sharp, bruised pain on plantar surface (anterior to calcaneus or in arch)

  • Worst with first steps after immobility (e.g. getting out of bed)

  • Pain subsides with movement, returns with fatigue or prolonged standing

  • Excessive running, especially in old/worn-out shoes

  • Obesity / Overweight

  • Sudden increase in activity levels

  • Unequal leg length

  • Flat/pronated feet

  • Jammed arches

  • Tight calf muscles

  • May occur as a complication of:

    • Gout

    • Rheumatoid arthritis

    • Diabetes

Hammer Toe

  • Deformity affecting 2nd toe

  • Muscle and tendon imbalance causes:

    • Hyperextension at MTP & DIP

    • Hyperflexion at PIP

  • Over time, muscles, tendons, and fascia shorten, becoming fixed

  • Visible toe deformity

  • Involuntary muscle contraction

  • Pain from friction (shoes)

  • Corns and calluses, especially on dorsal PIP joint

  • Becomes increasingly rigid over time if untreated

  • Contracture of soft tissues

  • Often associated with:

    • Bunions

    • Pes cavus (high arches)

  • Ill-fitting footwear:

    • High heels

    • Shoes that crowd toes or cause toe to curl

  • Trauma

  • Underlying conditions:

    • Diabetes

    • Rheumatoid arthritis (RA)

    • Osteoarthritis (OA)

Bunion

  • Deformity where the big toe (1st phalanx) is pushed laterally, toward the other toes

  • Joint capsule stretches

  • Bursa forms at irritated medial MTP joint

  • Callus develops over the protrusion

  • A similar issue at the little toe = “bunionette” or Tailor’s bunion

  • 10x more commen in Women

  • Visible bump on the medial side of the 1st MTP joint

  • Covered with callus

  • Area may be:

    • Red, hot, painful if bursa is inflamed
