POAT Unit 1 & 2Force = - answer mass * acceleration (F=ma)
Torque is also known as - answer moment of a force
F x Moment Arm Length - answer Torque
Pressure = - answer Force/area
Newton's first law tells us: - answer There is no resultant forces if the body is at rest
(therefore the forces are balanced)
ortho = - answer straight
"an externally applied device applied to a part of the body to correct deformity, improve
function, or relieve symptoms of a disease" is known as - answer Orthosis
Orthosis is a device which supports or assists the - answer Musculo-neuro-skeletal
system
Orthosis can be prescribed for any of the following objectives: - answer- immobilization
- joint protection
- joint control
- assisting w/ a specific function or movement
-provide feedback
- impart corrective forces on the msk system
T/F: Purpose of an orthosis is multifactorial - answer true
Orthotic devices are prescribed with a goal of: - answer either
- selectively controlling
OR
- assisting some type of movement or function
T/F: In the case that orthotic devices are prescribed to selectively control or assist some
type of movement or function, orthotics can substitute for inadequate supporting
structures (ligaments, bone, or muscle) - answerTrue
, T/F: Orthotic appliances have the ability to assist in regulation of muscle tone -
answertrue
Orthotic appliances may be indicated for conditions where: - answerjoints or bones
need protection from outside forces or when immobilization can relieve pain or irritation
Orthoses can substitute for the lack of: - answerintrinsic stability normally provided by
muscle, ligaments, tendons, or bone

important to account for: - answerwhat typical postural alignment entails; understand
what is atypical or abnormal BOTH statically and dynamically
PTs are involved with what regarding PT service and Orthoses? - answer1. Assessment
for identified purposes
2. Evaluation of fit
3. Education in orthotic fit and training in use
4. Assessment and quantification of functional benefits and uses
Orthoses can be classified into what two groups? - answerTemporary (aka off-the-shelf,
prefabs)
