A factor facilitating excessive knee flexion in midstance is what?

Soleus muscle weakness

Popliteus muscle weakness

hyperactivitiy of ankle PF

hip flexor weakness - CORRECT ANSWER: Hyperactivity of ankle PF

A rigid forefoot valgus deformity would lead to what during MS and terminal stance?

How would you fix this? - CORRECT ANSWER: Compensatory STJ supination in all

phases of gait.

Lateral forefoot posting, to get lateral boarder of foot to ground during phases

A rigid forefoot valgus malalignment with a STJ supination compensation. How would you use a wedge to fix this? - CORRECT ANSWER: Support forefoot on lateral plantar surface to bring ground up to foot

A rigid forefoot varus deformity would lead to what during MS and terminal stance? How

would you fix this? - CORRECT ANSWER: Compensatory STJ pronation.

Medial forefoot posting

A rigid forefoot varus malalignment, with a STJ pronation compensation. How would you

use a wedge to fix this? - CORRECT ANSWER: Support forefoot on medial plantar

surface

A rigid plantarflexed first ray deformity would lead to what during MS and terminal

stance? How would you fix this? - CORRECT ANSWER: Compensatory STJ supination.

What they should do it remove material under first ray, to make it even with the other rays

A single axis KAFO knee joint, may lock knee into hyperextension in which the

individual may do what? - CORRECT ANSWER: Pt will have to hip hike and use

circumduction

A solid AFO can assist in promotion of ankle and knee stability in stance. This can substitute for what weakness? - CORRECT ANSWER: Substitute for weakness of PF or weak inverters/evertors

A solid AFO can assist in swing foot clearance. This can substitute for what weakness?

- CORRECT ANSWER: Substitute for weak DF

A solid AFO can preposition the foot for what phase of gait? - CORRECT ANSWER:

Initial contact.

Hold in subtalar neutral

A wrist orthoses must clear what two creases to allow normal movement? - CORRECT

ANSWER: Clear distal and palmar crease

An angle of what degrees is ideal oreinetation for a lever of an orthotics? - CORRECT ANSWER: 90 degrees (with perpendicular direction there are no other forces that would decrease the torque)

Articulated AFO's are used to permit sagittal plane motion, while restricting transverse and frontal plane motion.

Identify indications for use of an articulated AFO, for specific impairments - CORRECT

ANSWER: Excessive knee hyperextension, with 5 degree PF stop

Excessive knee flexion during midstance and terminal stance with DF stop to limit forward tibial translation, to limit excessive DF with weak PF

Provide medial and lateral stability to ankle and STJ

Before ordering an orthoses, what factors should be considered to see if the patient

could don an LE orthotic device? - CORRECT ANSWER: Sufficient ROM in Lower Ex

tremity joints to align segments

The ability (including cognition) and desire to meet ambulation goals

Adequate cardiovascular endurance and adequate Upper Extremity (UE) and Lower Extremity (LE) strength for the intended activity, i.e. ambulation

Sufficient strength to advance the limb

Briefly describe the acromioclavicular joint? - CORRECT ANSWER: Planar joint that allows for rotation and anterior.posterior movement of acromion on clavicle

Briefly describe the carpometacarpal joint of the thumb - CORRECT ANSWER:

Articulation between trapezium and first ray. 2 / 4

Saddle joint

Briefly describe the distal radioulnar joint? - CORRECT ANSWER: Made up of ulnar notch of radius to head of the ulna. Pivot joints

Briefly describe the distal transverse arch of the hand - CORRECT ANSWER: More

mobile arch.

Located at level of metacarpal heads and provides hand ability to grasp objects of different objects

Briefly describe the glenohumeral joint? - CORRECT ANSWER: Ball and socket joint in glenoid fossa and head of humerus.

Allows for multiple planes of motions, at the expense of stability in arm

Briefly describe the humeroradial joint - CORRECT ANSWER: Connects the capitulum of distal humerus to head of radius.

Hinge joint and only allows for flexion and extension

Briefly describe the humeroulnar joint? - CORRECT ANSWER: Made up of proximal

ulna and trochlea.

Hinge joint and only allows for flexion and extension

Briefly describe the longitudinal arch of hand - CORRECT ANSWER: Runs from carpal level through four digital rays and adapts to meet needs for grasping activities

Briefly describe the midcarpal joint - CORRECT ANSWER: Between proximal carpal

joints and distal carpal row.

Lunate, scaphoid, trapezius and pisiform to the trapezium, trapezoid, capitate and hamate bones.

Allows for flexion, extension and radial/ulnar deviation.

Briefly describe the proximal radioulnar joint? - CORRECT ANSWER: Articulation of the radial head to the radial notch of the ulna. Pivot joint to permit radius to pivot around ulna for supination/pronation

Briefly describe the proximal transverse arch hand - CORRECT ANSWER: Rigid

arrangement at level of distal carpal row,

• / 4

Briefly describe the radiocarapal joint - CORRECT ANSWER: Between the Distal

humerus and the scaphoid and lunate bone.

condyloid joint

Briefly describe the scapulothoracic joint? - CORRECT ANSWER: Pseudo joint that

allows the scapula to glide along the thoracic wall as arm moves

Briefly describe the sternoclavicular joint? - CORRECT ANSWER: Saddle joint that allows motion in several directions

Briefly describe the transverse arch of hand - CORRECT ANSWER: Space between

distal and proximal transverse arches

Carbon fiber thermoplastic or conventional KAFO?

Interchangeability of shoes

Better cosmesis

Lightweight

Can be hot

Hard to adjust - CORRECT ANSWER: Thermoplastic carbon fiber KAFO

Carbon fiber thermoplastic or conventional KAFO?

Strong, durable, easy to adjust

Less cosmetic

Heavier

Must be attached to shoe - CORRECT ANSWER: Conventional KAFO

Compare and contrast the differences between GRF and 3 point force, systems of control - CORRECT ANSWER: GRF: dependent on contact with ground

3 point: functions in both swing and stance

GRF: Dependent on shoe structure

3 point: not dependent

GRF: Influence over joints within orthosis and proximal

3 point: only joints within orthosis
