Manipulation/ Adjustment- 1

Question 0

Definition of an adjustment?

Answer 0

Specific form of joint manipulation using either long or short leverage techniques with specific contact. It is a low amplitude dynamic thrust of controlled velocity, amplitude and direction

Question 1

Definition of a manipulation?

Answer 1

• passive manual manoeuvre during which a synovial joint is carried suddenly beyond the normal physiological range of movement without exceeding the boundaries of anatomical integrity (anyone can manipulate, not everyone can adjust)

Question 2

What is the cracking sound of a cavitation?

Answer 2

Gas being released into the synovial joint. It takes 20 minutes for the gas to re-dissolve and for the joint to be able to be re-adjusted

Question 3

What are the 4 stages of joint manipulation?

Answer 3

Grade 1: active range of movement
Grade 2: passive range of movement
Grade 3: para physiological space
Grade 4: extraphysiological space or limit of joint integrity

Question 4

Specific VS general adjustment

Answer 4

Specific: focus force to one articulation, typically utilise short levers, use of specific vectors of correction
General: broader contact, influence multiple segments, longer levers typically utilised

Question 5

Cavitation

Answer 5

The normal range of movement of any synovial joint has been termed the physiological zone. Before the application of the thrust phase of an HVLA manipulation a preload force is applied. This involves taking the viscoelastic synovial fluid to a well defined elastic barrier characterised by increased stiffness. The additional thrust which creates movement between the articular surfaces of the joint is ultimately delivered to the SF. Cavitation occurs when the articular surfaces are separated through the elastic recoil of the SF above a critical velocity causing the SF to fracture or crack open like a solid
