Q

Components of Motion

A
  • Direction: flexion, extension, sidebending, rotation
  • Range: actual measurements in degrees
  • Quality: smooth = normal, ratcheting (parkinsons disease), restricted = contracture or SD, exhibiting resistance to the motion induced (ex. Cerebral Palsy)

Q

End Feel of ROM

A
  • Elastic: like rubber band
  • Abrupt: OA or hinge joint
  • Hard: somatic dysfunction
  • Empty: stops due to guarding (intentionally done by patient)
  • Crisp: involuntary muscle guarding as in pinched nerve

16
Q

Flexibility: Dynamic

A

ROM an athlete can produce and speed at which they can produce it

17
Q

Flexibility: Stiffness

A

reduced ROM of a joint or group of joints

18
Q

Does Active or Passive ROM have the greatest range?

A

Passive

19
Q

___ Spine displays the most motion

A

Cervical (C1-C7)

20
Q

Functional Unit of Spine

A

two vertebrae, their associated disc, neurovascular, and other soft tissues

21
Q

Coupled Motion

A

consistent association of a motion along or about one axis, with another motion about or along a second axis; the principle motion cannot be produced without the associated motion occurring as well

22
Q

Linkage

A
  • relationship of joint mechanics with surrounding structures
  • by linking multiple structures together you will get increased ROM (ex. shoulder-spine, spine-hip/pelvis)
23
Q

Ehler-Danlos Syndrome

A
  • collagen dysfunction
  • joint hypermobility
  • stretchy skin
  • distinct lack of ROM barrier
  • diagnosed using Brighton Criteria – must have 4/9
24
Q

Somatic Dysfunction

A

the impaired or altered function of related components of the somatic (bodywork) system including the skeletal, arthrodial, and myofascial structures, and their related vascular, lymphatic and neural elements

25
Q

Skeletal Dysfunction

A
  • hard end point
  • Ex. OA, RA, somatic dysfunction
26
Q

Myofascial Dysfunction

A
  • tight, elastic end point
  • Ex. scar tissue, somatic dysfunction
27
Q

Arthrodial Dysfunction

A
  • hard end point
  • Ex. OA, RA, somatic dysfunction
28
Q

Vascular Dysfunction

A
  • empty end feel
  • Ex. peripheral vascular disease, thoracic outlet syndrome, somatic dysfunction
29
Q

Lymphatic Dysfunction

A
  • empty or boggy end feel
  • Ex. lymphedema, visceral dysfunction (CHF), acute injury, somatic dysfunction
30
Q

Neural Dysfunction

A
  • crisp or empty end feel
  • Ex. herniated disc, thoracic outlet syndrome, somatic dysfunction
