History of Manual Therapy

Hippocrates

• 460-355 BC

Claudius Galen

• 131-202 AD

Bone Setting

• Britain 17th and 18th centuries

• practice passed from father to son

• along with barber surgeons were the forerunners to orthopedics and surgery in the UK

• Mid 20th century bone setting dies out and is replaced by physical therapy and osteopathy

Osteopathic Medicine

• Andrew Taylor Still – 1874

• DO Doctor of Osteopathy in the USA –1928– Osteopathic Physicians– gained equal rights with MD’s

• In all states by 1970

• William Garner Sutherland – 1966– offshoot of osteopathy

• cranial osteopathy– cranialsacral technique

Chiropractic

• Daniel David Palmer – 1895– founder of chiropractic – credits it to medicine– claims to be the first to reposition vertebrae by

using the spinous and transverse processes as balance levers

Manipulation in Medicine

• medicine created physical therapy to aid in rehabilitation

• physicians trained aids who later became physical therapist

• 1899 physiotherapy founded in England– James and John Mennell – 1st to use term MT– Edger and James Cyriax

Physical Therapy

• 1921 physical therapy est. in USA– American Women’s Physical Therapeutic

Association– need to use medically trained women after

WW1

• 1927 – ‘Arthrokinematics’ - used in Gray’s Anatomy

Physical Therapy

• 1957 – James Cyriax– Textbook of Orthopaedic Medicine

• 3rd edition

– Soft Tissue Differentiation– popularized the term ‘end-feel’– trained physiotherapists– pleaded for emphasis first on

evaluation and then on treatment

Freddy Kaltenborn

• 1961 – Kaltenborn – Norway– Extremity Joint Manipulation– After 1971 began instructing

physical therapists worldwide

Olaf Evjenth

Paris - Maitland

• 1963 – Stanley Paris (USA) –PT– while in NZ– The Theory and Technique of Specific

Manipulation

• 1964 – Geoffrey Maitland (AUST) – PT– Vertebral Manipulation

IFOMT

• 1966 – Paris, Grieve, Maitland, Kaltenborn– met with others to discuss setting up an

international body• 8 years later IFOMT (Montréal)

Robin McKenzie

• late 1970’s

• popularized the concept of

spinal extension for

treatment of LBP– ‘centralization theory’

Brian Mulligan

• 1990’s – Brian Mulligan (NZ)– MWM’s

Current Manual Therapy

• practice by physiotherapist is quite eclectic• no single philosophy dominating• rarely used in isolation, but with:

– therapeutic exercise– patient education– supportive modalities

• most use:– mechanical– muscle energy– oscillatory

Arthrology

Arthrology

• Outline:– joint classification– shapes of articular surfaces– planes and axes– degrees of motion/freedom– arthrokinematics– osteokinematics

Arthrology

Joints(Arthroses)

Solid Joints Cavitated Joints

(Synarthroses) (Diarthroses)

Fibrous Cartilaginous Synovial

Fibrous Joints

1. Sutures

2. Gomphoses (peg and socket- teeth)

3. Syndesmoses– has interosseus ligament

• eg. inferior tibiofibular ligament

Cartilaginous Joints

Synchondroses (primary cartilaginous joints)hyaline growth cartilage (function = growth mechanism)

- sternales, xiphosternalisSymphyses (secondary cartilaginous joints)

hyaline growth cartilage, bonded by fibrocarilaginous disc

- pubis, intervertrebrales, manubriosternalis **

Synovial Joints

• Typical features:– freely moveable– articular surface predominantly hyaline

cartilage, sometimes fibrocartilage– fibrous joint capsule– synovial membrane– synovial fluid– disc or meniscus– joint space

Synovial Joints

Complexity1. Simple

• one pair of articulating surfaces:• convex• concave

2. Compound• more than one articulating pair in a single capsule• neither will articulate with the surface that belongs to the

other

3. Complex• has an articular disc

Shapes of Articular Surfaces

1. Ovoid

2. Sellar

Ovoid

• concave or convex in all planes• degree of curvature will vary in all planes• egg shaped rather than spherical1. Unmodified ovoid

– shape is spherical enough to allow 3 degrees of motion (Hip)

2. Modified ovoid– degree of curvature is more marked in one plane than

the other– allows only 2 degrees of motion (MCP)

Sellar

• saddle shape• predominantly concave in one plane and and convex at right

angles to this• stable and efficient, requires fewer ligaments as surface is

more congruent1. Unmodified Sellar

– joint surfaces are purely concave in one plane and purely convex in the other (perpendicular to each other)

– allows for 2 degrees of motion (1st CMC)

2. Modified Sellar– joint surfaces have both a concave and a convex portion in the same

plane (not perpendicular to each other)– allows for only 1 degree of motion (TCJ, HUJ)

Planes and Axes

PLANE AXIS

median/sagittal transverse

(divides R/L) (runs M/L)

frontal/coronal sagittal

(divides A/P) (runs A/P)

transverse/horizontal vertical

(divides S/I) (runs C/C)

Degrees of Motion

• The number of planes through which a bone can be voluntarily (actively) moved around (3max)

Mechanical Axis– a line passing through the bone perpendicular to the

joint surface

– line of reference for osteokinematic motion

Axis of Movement– bone moves around this point

– perpendicular to the plane of motion

One Degree of Motion

• uniaxial– hinge joints (ulnohumeral)

• movement of the bone is limited to movement about a single axis

• motion of a bone is produced by a sliding action within a joint

Two Degrees of Motion

• biaxial– ellipsoidal (MCP, wrist)– pivot

• either a swing or spin

• has spin and swing or two distinct swings

• axes must be perpendicular to each other

Three Degrees of Motion

• multiaxial– spheroidal - ball & socket (hip)– planar joints (AC jt)

• movement about 3 distinct axes which are perpendicular to each other

• has a spin and two distinct swings (near pure)

Degrees of Freedom

• the number of independent axes that a bone can move around (6 max)

• axes are perpendicular to each other

• 3 rotations

• 3 translations

Degrees of Freedom

• 3 rotations

• 3 translations

Degrees of Freedom

Arthrokinematics

• study of the movement of one articular surface on another without regard to the movement of the bone or the forces producing that movement

• in the periphery, movement is named after the direction of motion of the distal bone

• in the spine, movement is named by motion of the superior bone

• describes:1. spin2. rock (concave moving)

roll (convex moving)3. glide (slide)4. traction/compression

Arthrokinematics

Convex/Concave Rule

• the relationship between the shape of articulating joint surfaces and the direction of gliding is defined by the convex/concave rule

• if the concave surface is moving on a stationary convex surface, gliding will occur in the same direction as the rocking motion

• if the convex surface is moving on a stationary concave surface, gliding will occur in an opposite direction to the rolling motion

Arthrokinematics

Arthrokinematics

Osteokinematics

• study and measurement of motion of a bone in space

• study of movement of a bone around its mechanical axis without regard to the motion occurring at the joint

• describes:– rotations

• spins• swings

– translations

Rotation

Spin

• the non-linear motion that occurs either at the joint surface (arthrokinematic spin) or around the mechanical axis of the bone (osteokinematic spin)

• motion of the bone is produced by a twisting action

Swing

• the linear motion that either occurs at the joint surface (arthrokinematic swing) or in the plane of the mechanical axis of the bone (osteokinematic swing)

• motion of the bone is produced by a sliding action within a joint

Pure Swing

• (cardinal or chordal)• shortest distance between two points• swing with no accompanying spin• bone moves in one plane• swing can occur without the bone taking a curved

path• only occurs in joints that have at least 2 degrees of

motion• is functionally abnormal and the exception rather than

the rule

Pure Swing

Impure Swing

• (arcuate)

• Is accompanied by spin (conjunct rotation)

• The bone does not stay in one plane

• Movement of a point on the mechanical axis follows a line (arc) other than the shortest one (chord)

Impure Swing

Translation

• all particles in the body at at given time have the same direction of motion relative to a fixed point

• there is no centre of rotation as the bone moves along a plane instead of through it

Translation

PPM/PAM

• Passive Physiological Movement– links with osteokinematics

• Passive Accessory Movement– links with arthrokinematics
