25
Q

The extent of osteokinematic motion available for movemet activities, functional or otherwise, with or without assistance

A

Range Of Motion

26
Q

How to perform ROM (reps, sets, holds)

A

1 x 5-10 reps of each movement

27
Q

The ability of a muscle to lengthen, allowing one joint or a series of joints in a limb to move through range of motion

A

Muscle Flexibility

28
Q

The muscle is slowly elongated to tolerance (a mild stretch, short of pain) and the position is held for 30 seconds. Mild tension should be felt in the muscle being stretched

A

Static Stretching

29
Q

How to perform a static stretch (reps, sets, holds)

A

Hold for 30-60 seconds

30
Q

Indications for stretching

A
  • ROM limited due to adhesions, contractures, scar tissue, causing functional limitations/disability
  • Structural limitations otherwise preventable
  • Muscle weakness/shortening of opposing tissue
  • Part of the fitness program
  • To minimize post exercise muscle soreness
31
Q

Contraindications for stretching

A
  • Bony block limits joint motion
  • Recent fracture
  • Evidence of an acute infection
  • Soft tissue healing could be disrupted
  • Sharp pain with joint movement
  • Hematoma or tissue trauma
  • Hypermobility
  • Short tissue is beneficial to Pt.
32
Q

Type of stretch where

  • the limb is moved passively to the end ROM
  • the pt. contracts the muscle for 10 seconds
  • the limb is moved further into the ROM
A

Autogenic Inhibition

33
Q

Type of stretch where

  • the limb is moved passively to the end ROM
  • the pt. performs concetric contraction in the opposite muscle, causing a greater stretch of the muscle
  • the pt. relaxes and the stretch is held 10-15 seconds
A

Reciprocal Inhibition

34
Q

Muscle tension occurs, but there is no movement or change in muscle length

A

Isometric Contraction

35
Q

What is the recommended hold time for Isometric Exercises

A

6-10 seconds

36
Q

Muscle contraction which occurs against a constant resistance, and results in joint motion

A

Isotonic Contraction

37
Q

Muscle contraction which results in shortening of the muscle

A

Concentric Contraction

38
Q

Muscle contraction which results in lengthening of the muscle

A

Eccentric Contraction

39
Q

Isokinetic Contraction

42
Q

Which type of contraction is most likely to result in DOMs

A

Eccentric Contraction

43
Q

How to perform isotonic exercises (sets, reps, holds)

A

3 sets of 10 reps

44
Q

How to make an effective TherEx program

A

TherEx programs should incorporate a variety of theraputic exercises which are designed to improve function

45
Q

Define 1 rep Max

A

The amount of resistance/weight in which a muscle can overcome in a single movement 1 time

46
Q

How is a patient’s 10 rep Max used in PT practice?

A

The patient will usually do an exercise in 3 sets of 10 reps. The first set would be 50% of their 10 rep max weight, the second would be 75%, and the third would be 100% (DeLorme’s Progressive Resistance Exercise)

47

  • Stiffness and tenderness to touch
  • May last for up to one week, but generally resolves in 72 hours

Q

Normal resting heart rate

A

60-100 BPM

51
Q

Normal resting blood pressure

A

<120/<80

52
Q

What is the normal responce to blood pressure during aerobic activity

A

Systolic pressure should rise with the amount of exertion, but Diastolic pressure should rise no higher than 10 mmHG

53
Q

Abnormal responses to Exercise

A
  • Angina
  • Unusual or severe shortness of breath
  • Abnormal diaphoresis
  • Pallor, cyanosis, cold and clammy skin
  • Central nervous system symptoms (vertigo, ataxia, gait problems, or confusion)
  • Leg cramps or intermittent claudication
  • Physical or verbal manifestations of severe fatigue or shortness of breath
54
Q

Blood pressure guidelines for aerobic activity

A

Stop if:

  • SBP drops by 20 mmHG or doesn’t rise
  • SBP >260, DBP >115
55
Q

Reduction of cell size

A

Atrophy

56
Q

Increase in cell size

A

Hypertrophy

57
Q

Increase in number of cells

A

Hyperplasia

58
Q

Decrease in number of cells

A

Involution/Hypoplasia

59
Q

Change of a cell from one type to another

A

Metaplasia

60
Q

What are the cardinal signs of inflammation

A
  • Heat
  • Redness
  • Swelling
  • Pain
61
Q

When a joint has reached it’s end ROM, because the surrounding soft tissue cannot stretch any further

A

Passive Insufficiency

62
Q

When a muscle cannot contract anymore, because it has shortened as much as it possibly can

A
