Q

What’s the goal of pad construction

A

To decrease injury potential

  • increase the impact area band transfer forces
  • limit motion of a body part
  • reduce friction between contact surfaces
  • absorb energy
  • resist absorption of bacteria,fungi, & virus
17
Q

What are the different types of knee braces

A

Prophylactic
Functional
Rehabilitative
Patellofemoral

18
Q

What does a prophylactic knee brace consist of

A
  • bilateral or lateral bar design

- graphite and aluminum disperse forces during low impact activites

19
Q

What are the problems with prophylactic knee braces

A
  • little impact on proprioception and gait
  • may inhibit strength and speed during running
  • AAOS conclude that they are ineffective in reducing knee injuries
  • may even contribute to injury
20
Q

What does the function knee brace consist of

A
  • AKA de-rotation or ACL brace
  • limit tibial rotation and extension
  • straps and shell
21
Q

What does performance depend on for functional knee brace

A
  • anterior shear load

- patient comfort

22
Q

What are the factors effecting functional knee brace

A
  • attachment technique
  • hinge design
  • limb contours
  • type of attachment
  • materials
  • displacement between brace and soft tissue
23
Q

What does a straight immobilizer for the knee consist of

A
  • light weight
  • made of foam with hard plastic or metal
  • no flexion ROM allowed
24
Q

What does the hinged rehabilitative knee brace consists of

A
  • ROM is set by the clinician

- double adjustable hinged

25
Q

What does the patellafemoral brace consist of

A
  • silicone pad sewn into neoprene sleeve to relieve tension

- chopat strap over infrapatellar ligament also may relieve pain

26
Q

What are the goals of patellofemoral braces

A
  • dissipate forces
  • maintain patella alignment
  • improve patellar tracking
27
Q

What are the different types of ankle braces

A
