Q

RF varus and flexible FF valgus, what happens

A

Significant pronation is seen during stance. As the STJ begins to pronate the MTJ becomes mobile causing even more pronanation an dmaking the FF valgus flexible

Callus formation on the 1st and 2nd MH

Q

Functional elements of gait

A

limb stability

  • challenged by the height of COM
  • changing body segments

Progression

  • forward fall of the body
  • swing limb momentum

Energy conservation

  • using momentum to substitute for muscle power
  • displacement of the body in all planes (determination of gait)

Q

Knee flexion LR-MSt

A

Determinant of gait that conserves energy by lowering vertical displacement of the CofG during LR-MSt

Knee flexion after knee strike decreases the vertical height of the CofG by 7/16

Q

What are the intrinsic and extrinsic causes for excess pronation

Study These Flashcards
A

Intrinsic

  • FF Varus & 5th ray
  • PF 5th ray
  • RF Varus
  • FF valgus & 1st ray

Extrinsic

  • Tibial varum
  • internal tibial and femoral version
  • obesity
  • muscle imbalance (spastic peroneals)
  • small gastrocs
  • muscle spasms (eg. RA)
23
Q

Initial Swing

Study These Flashcards
A

Definition: the thigh begins to advance as the foot comes off the floor (62-75 percent)

Kinematics

  • A 5 degress PF
  • K 60 degrees Flexion
  • H 15 degrees flex

Kinetics

  • A ext PF due to weight distribution of
  • K thigh advancement and tibial inertia (flex torque)
  • H tibial inertia maintain hip ext torque

Muscles

  • A dorsiflexors
  • K biceps femoris and sartorius
  • H R.F. iliacus, adductor longus, gracilis
24
Q

Treatment theories for scoliosis. Essential components when fabricating, fitting/ modifying

Study These Flashcards
A

-Stable pelvic base

outrigger or extension to implement corrective forces

  • force couples
  • lumbar corrective forces apply pressure on transverse processes
  • thoracic corrective forces apply pressure to ribs
25
compression stress
shortening forces perpendicular to cross sectional areas
26
tensile stress
lengthening forces
27
shear stress
oblique external load, stress in parallel to surface
28
young's modulus
measurement of the slope of stress strain curve, in a measurement of the elastic deformation stage and in a measurement of stiffness
29
what are true/false and floating ribs
true- direct articulation (1-7) false- indirect articulation (8-10) floating- no articulation (11-12)
30
what does intercostal space contain
muscle fascia, vessels and nerves
31
femoral neuropathy
loss of function
32
spinal nerve and curves pass through
intervertebral foramina
33
axial skeleton
skull, spine, ribs sternum manubrium
34
appendicular skeleton
shoulder girdle, pelvic gridle and limbs
35
fibrous capsule
circumferential and encapsulates the entire acetabular rim and femoral neck. stabilizes the joint
36
acetabular labrum
surrounds the acetabulum and increases surface area of the socket but sacrifices mobility
37
acetabular labrum
surrounds the acetabulum and increases surface area of the socket but sacrifices mobility
38
transverse ligament
bridges the acetabular notch
39
ischiofemoral ligament
posterior O: body of the ischium I: medial to GT Prevents extension and internal rotation
40
Intertrochanteric crest vs intertrocanteric line
crest is posterior line is anterior both connect the GT to the Lesser T
41
Iliofemoral ligament
Anterior O: anterior inferior iliac spine I: intertrochanteric line Prevents extension and adduction
42
Pubofemoral ligament
Inferior medial O: iliopubic eminence I: inferior neck of the femur Prevents abduction and some extension
43
Rib humb
Prominence of the ribs on the convexity side of the curve due to vertebral rotation and is measured by the forward bend test (Adams)
44
FF valgus
forefoot wrt to the rearfoot in an everted position compensation - STJ supination (LR-MSt) to bring the lateral side of the foot down - callus formation is on the 1st and 5th MH uncompensated -BW on the medial aspect of the foot complications -lack of shock absorption and knee pain
45
Spina bifida
neural tube defect resulting in malformation of the neural tube. results in impairments below the lesion level. UPPER and LOWER
46
Cystica myelomeningocele
meninges and S.C protrude through the spinal column in a cystic sac. accompanied by neural deficit below the lesion level
47
cystica meningocele
meninges protrude through the spinal column while the spinal cord remain intact
48
occulta
meninges and SC remain intact. dimple and small tuft of hair are the only symptoms
49
Terminal Swing
the knee extends the limb to prepare to contact the ground for initial contact Kinematics A- Neutral K- 5 degrees flexed H- 20 degrees flexed Kinetics A- int df moment K- tibial momentum causing external extension moment H- tibial momentum causing external hip flexor moment Muscle A- dorsiflexors K- quads H- hamstrings decelerate and gluteals prepare for IC in frontal plane
50
Terminal Stance
forefoot provides the locker where the feet and limb move forward to allow progression of the stance limb Kinematics A- 10 degrees DF K- 5 degrees F H- 20 Extend Kinetics A- anterior K- Anterior H- Posterior Muscle A- PF, Tib post, Peroneals K- Biceps Femoris H- Illiofemoral Ligament, TFL
51
List ways to measure maturity and growth remaining for scoliosis patient
- riser sign - Menarch 2 years after left of growth - wrist bone - vertebral epiphysis
52
Mid Swing
The thigh continues to advance and the knee begins to extend Kinematics A- Neutral K- 25 degrees Flexed H- 25 degrees Flexed Kinetics A- internal DF moment K- tibial momentum creating knee extension moment H- tibial momentum creating hip flexor moment Muscles A- DF K- extension controlled by hamstring H- controlled by hamstring
