Mobilzation/Dynamic Splint

Question 1

Used to imply active force

Answer 1

Mobilization/Dynamic Splint

Question 2

Involves an elastic force

Answer 2

Dynamic

Question 3

Best Used in proliferative stage

Answer 3

Dynamic

Question 4

Two types of mobilization splints that hole the target structure at maximum length. NO elastic involved.

Answer 4

Static Progressive.
Serial Static.
Both can be used in chronic stages.

Question 5

Three Reasons to Use a Mobilization Splint

Answer 5

1. To increase joint motion.
2. Realign and/or maintain joint alignment allowing for controlled motion.
3. Substitute for weak or absent motion.

Question 6

Long standing dense scar tissue with loss of motion works best with what two splints.

Answer 6

Serial Static or Static Progressive

Question 7

Equipment/Features of Dynamic Splinting

Answer 7

Rubberbands, elastic thread, fishing line, velcro, tapped velcro, springs, eyelets, finger hooks, screw posts.

Question 8

A projection from the splint base that the therapist uses to position a mobilizing force.

Answer 8

Outriger.

Must me at a 90 degree angle.

Question 9

Two classifications of outriggers

Answer 9

High profile- easier adjustments.

Low profile- more cosmetically appealing.

Question 10

Theory Behind Mobilization Splinting

Answer 10

Controlled tension over a prolonged period alters cell proliferation.
Results in tissue LENGTHENING not stretching.

Question 11

Goal for Mobilization Splinting

Answer 11

Increase joint motion.

Promote normal full ROM with minimal inflammation and scar tissue.

Question 12

An action or influence that either arrests, produces or changes the direction of motion.

Answer 12

Force

Question 13

4 details regarding force.

Answer 13

1. type of force (push/pull)
2. magnitude of force.
3. Line of angle of application (direction in which the force acts)
4. Point of application (location on the structure at which the line of force is acting on.

Question 14

Continual tissue elongation in response to constant force at the correct magnitude applied to tissue over a prolonged period of time.

Answer 14

Creep.

Question 15

Goal of Creep

Answer 15

Allow creep without tissue injury

Question 16

The effect of force on the rotational movement of a point.

Answer 16

Torque

Question 17

Torque =

Answer 17

force x length of moment arm

the greater the moment arm, the greater the mechanical advantage.

Question 18

(magnitude of force) x (distance from the joint)

Answer 18

Less force is needed to create movement if you apply the force further away from the joint you are affecting.

Question 19

How to decide how much force is needed

Answer 19

Patient Reports.

Gentle stretching, no blanching (turns white), no redness, and no inflammation.

Question 20

How long should you wear a dynamic splint that is creating force

Answer 20

TERT= Total end range time. 
Initially: 30 min - 2 hours. 
Then check for patient reports.
Can wear up to 23hrs. a day/7 days a week.
6 hours TERT 
Usually don't wear during HS

Question 21

Angle of application of mobilization

Answer 21

90 degrees to the lever

Question 22

Results from the force being pulled parallel to the surface

Answer 22

Sheer Force.

Question 23

Sheer force can result in

Answer 23

the splint sliding along the surface and not staying in place.

Question 24

Casts or splints that are applied with the tissue at maximum length (gentle end range)

Answer 24

Serial Static Splint

Question 25

Characteristics of Serial Static Splints

Answer 25

Easy to apply, minimal supplies and set up. | Plaster cast.

Question 26

Serial Static Splint Wear Schedule

Answer 26

24 hours, replace every 2-3 days.

Question 27

Precautions of Serial Static Splints

Answer 27

Leave finger tip exposed so you/they can observe for restriction in circulation. Keep dry.
