what is AROM?

A

active ROM

60
Q

A

Passive ROM

61
Q

What is RISOM?

A

RESISTED ISOMETRIC CONTRACTRACTION

62
Q

What type of range of motion is described by “The person moves a given joint through its possible range independently”

A

AROM

63
Q

what can be assessed by evaluating arom?

A
  • quality of physiologic motion
  • patients willingness to move
  • assess level of pain
  • assess both inert and active structures responsible for movement
  • assess muscle compensations
  • assess the quality of movmt
  • evaluate patterns of motion restriction
64
Q

what does full and pain free arom suggest?

A

normalcy for that mvmt

65
Q

how should the PT be positionned when assessing the patients AROM?

A

where you can observe the motion as well as the client’s facial
expressions, which may reveal pain

66
Q

how to evaluate AROM

A
  1. have patient in an upright posture
  2. demonstrate the motion that the client needs to preform
  3. ask patient to accomplish motion on unaffected side and then on the affected side; look for limitations, breaks, symmertry and normal rythmn
  4. ask about pain/stretch/ feeling blocked
  5. measure and record finding using goniometer
67
Q

when testing AROM when should painful movements be performed

A

at the end if possible

68
Q

what happens if AROM is not full?

A

overpressure is applied with extreme care to prevent the exacerbation of symptoms

69
Q

what happens if AROM is full

A

overpressure may be carefully applied to determine the end feel of the jount

70
Q

why is the normal unaffected side tested first?

A

provides a baseline/comparaison as to what should be expected

71
Q

are active or passive movement done first in an objective exam?

A

active before passive, provides an idea of what the patient thinks he can accomplish

72
Q

what is PROM

A

ccurs when the client is resting and the therapist moves a joint through its possible range. The joint is taken through its full possible motion

73
Q

what can the PT determine from PROM?

A

the end feel of a joint or its limiting factors by applying over pressure

74
Q

what is end feel of a joint?

A

is the sensation transmitted to the therapist’s hands at the extreme end of the PROM and indicates the structures that limit the joint movement

75
Q

what can be provided by the end feel of a joint

A

significant insight into the health and function of passive or inert stabilizers (ligaments, joint capsules) as well as the ms/tendons being stretched during movement

76
Q

how should the patient be positionned when assessing PROM?

A

comfortable and supported position where support surrounding the joints is applied to protect and maximize relaxation

77
Q

what should the PT ensure as he preforms PROM?

A

Inquire about pain or discomfort that may be felt by the patient

78
Q

what should be recorded by the end of PROM?

A

THE END RANGE OF THE JOINT, IDENTIFY IF THE END FEEL IS NORMAL OR ABNORMAL AND DOCUMENT FINDINGS USING GONIOMETER

79
Q

What is end feel? what can it indicate

A

quality of resistance at end range; can indicate to the clinician the cause of motion restriction

80
Q

what is normal end feel when does it exist?

A

exists when there is full PROM at the joint and the normal anatomy of the joint stops the movement

81
Q

what are the 4 healthy types of end feel?

A
  • bony
  • capsular
  • elastic
  • soft tissue approximation
82
Q

what is a boney/hard end feel a result of? provide an example

A

he contact of the two bones is limiting the mvmt (eg. Elbow extension)

83
Q

what is capsular end feel? provide an example?

A

joint capsule provides firm limitation; hard arrest to movement with some give when the capsule or ligaments are stretched (eg. Internal rotation hip)

84
Q

what is elastic/muscular end feel?

A

stretching of ms/tendons – more elastic feel – shoulder abduction (teres major and lat dorsi)

85
Q

what is soft tissue approximation end feel? provide an example

A

tissues meet each other and stop the movement – eg. Elbow and knee flexion

86
Q

when is an abnormal end feel obtained?

A

exists when there is either a decreased or increased passive joint ROM or when there is normal PROM but structures other than the normal anatomy stop the movement

87
Q

how can abnormal end feel be determined?

A 
presence of muscle spasms
springy block or loose/soft endfeel
spongy
early capsular
hard
empty
88
Q

what is a muscle spasm in the case of abnormal end feel. provide an example

A

protection mechanism – feels jerky or shaky – injured tissue (ms, tendon or joint) e.g pain or ms strain

89
Q

what is springy block in the case of abnormal end feel?

provide an example

A

bouncy stoppage that occurs prior to end range – usually torn cartilage, or foreign body in the joint – e.g. meniscus in the knee

90
Q

what is loose/soft end feel? provide an example

A

abnormal motion is allowed where a ligament or joint capsule should prevent it e.g torn ligament

91
Q

what is spongy end feel? what does it indicate? provide an example

A

squishy or boggy – indicating swelling in the joint e.g. acute ligament sprain or inflamed bursa

92
Q

what is early capsular end feel a result of?

A

hypomobility

93
Q

what is hard end feel a result of? provide an example?

A

bone contacts bone, or a bony grating sensation when rough articular surfaces move past one another- example a joint that contains loose bodies, degenerative joint disease , dislocation or fracture

94
Q

what is an empty end feel? provide an example?

A

produced solely by pain (pt unable to tolerate more), therapist feels no tissue resistance – usually indicative of serious pathology (neoplasm, fracture, extra-articular abscess, acute bursitis or joint inflammation)

95
Q

what is important when assessing PROM?

A

For Passive ROM it is not only the amount (i.e. degree) of movement available but also the quality (end feel) of the motion that is important

96
Q

What are contractile tissues? provide examples?

A

Structures that are stressed with a ms contraction

ex: the muscle bellies, tendons, tenoperiosteal junction, submuscular/tendinous bursa

97
Q

what is inert tissue?

A

Joint capsule, ligaments, bursa, articular surfaces of the joint, synovium, dura, bone, and fascia

98
Q

when does RISOM occur?

A

Occurs when the client meets the resistance of the therapist in attempting to produce movement at the joint

99
Q

what is RISOM used to assess?

A

the health and function of contracting muscles and their corresponding tendons

100
Q

what work together in RISOM?

A

The nervous system, ms fibers and tendons all work together to generate force against gravity and the therapist’s resistance

101
Q

How is RISOM tested?

A

done with the joint in neutral or resting position so that stress on the inert tissue is minimal. patient is in a well aligned posture, therapist in in a position where it can resist movement adequately and evaluate facial expressions

102
Q

what should be done when assessing RISOM to decrease the compensation and maximize the ability to target specific muscles?

A

tabilize the joint proximal to the one being tested either positionally or with your other hand.

103
Q

what command is said to the patient in order for him/her to match the resistance your are applying?

A

dont let me move you

104
Q

should the patient overmatch the resistance you are applying?

A

no, it should results in an isometric contraction of the muscle

105
Q

what should the PT look for when assessing RISOM?

A

Look for strong/weak side

inquire about pain and discomfort

106
Q

what side should be the first assessed in RISOM?

A

UNAFFECTED SIDE

107
Q

if a muscle is identified as being weak in RISOM what is the following step?

A

proceed to manual muscle testing of the given individual muscle

108
Q

why may AROM/PROM/RISOM be repeated several times and held for a certain amount of time?

A
  • to see whether symptoms increase or decrease
  • to see if a different pattern of movement results
  • whether there is an increased weakness
  • determine if there is possible vascular insuFficency
109
Q

what information is provided by AROM?

A

gives us information on the pt’s willingness to move, if there is a contractile problem or inert problem, ms spasm, and pain

110
Q

what info is provided by PROM?

A

gives us information on inert structures (joint, ligament), contractile structures and end feel etc.

111
Q

what info is provided by RISOM?

A

gives us information on the strength and health of muscles and tendons (contractile structures)

112
Q

What is palpation

A

The examination of the body surface by touch, usually as a diagnostic aid.

113
Q

what is palpation performed?

A

performed to assess
Bony and soft tissue contours Soft tissue consistency
Skin temperature and texture

114
Q

what is involved with palpation?

A

locating a structure
becomming aware of its characteristics
assessing the quality or condition so you can determine how to treat it

115
Q

what must the PT be able to do in order to properly palpate?

A

dentify bony or soft tissue irregularities and to recognize structures that require direct treatment
locate the bony landmarks adequately
determine the presence of muscle contraction when assessing strength or conducting reeeducation exercises
locate structures that need to be stabilized to isolate jount mvmt when mobilizing a joint

116
Q

how should th patient be during palpation?

A

made comfortable
kept warm
body or body part is well supported to relax the muscles adequately to allows to palpate deep or inert structures

117
Q

what are guidelines for palpation for the PT?

A
  • short nails
  • visually observe region being palpatied
  • palpate with pads of index and middle finger
  • fingers are in direct contact with skin
  • provided a feeling of security to the patient
  • avoid poking
118
Q

how is a muscle palpated?

A

the patient will isometrically contract the muscle against resistance then followed by a relaxation, muscle is palpated in both contracted and relaxed phases

119
Q

how to palate a tendon?

A

The tips of the index and middle fingers are placed across the long axis of the tendon and gently rolled forward and backwards across the tendon

120
Q

what is required for proper palpation?

A

Receptive hands and fingers Open eyes
Listening ears
Calm breath
Quiet mind

121
Q

what are the 3 principles of palpation

A
  • move slowly
  • avoid excessive pressure
  • focus on what ut is you are feeling, be present
122
Q

what should the PT warn the patient about at the end of the objective exam why?

A

that he or she may experience exacerbation of symptoms as a result of the assessment
a good exam involves stressing different tissues and it will prevent the patient from thinking that the inital treatment has made them worse

123
Q

what happens if the conclusion following examination happens to be beyond the scope of the PT?

A

he examiner should not hesitate to refer the pt to another appropriate healthcare professional
