25
Hypermobility
ability to move a joint beyond the normal ROM excessive motion at a single or series of joints
26
Beighton criteria
general tool to measure joint looseness (laxity) or hypermobility
27
What is the classification of a contracture?
a joint hypomobility deficit
28
Contracture
loss of full PROM due to joint, muscle or other soft tissue limitations or alterations loss of PROM ranges from minimal, severe or complete where two bones are fused together there is no definite point where the loss of PROM is considered a contracture
29
Contraction
neuromuscular process that leads to tension development in muscles due to the interaction of actin and myosin (proteins)
30
3 ways contractures are named
by the action of the shortened muscle by the motion caused by the shortened tissue(s) motion opposite to the motion limited
31
What does the type of contracture influence?
whether ROM or stretching is needed the parameters of exercise
32
Myostatic contracture
musculotendinous (MT) unit is shortened causing a significant loss of ROM there is NO muscle pathology
33
Pseudomyostatic contracture
muscles appear to be constantly contracted due to a CNS lesion or response to pain/injury
34
Arthrogenic contracture
due to a joint pathology
35
Periarticular contracture
decreased extensibility of ligaments or the joint capsule
36
Fibrotic contracture
connective tissue changes (excessive deposition of ECM components, collagen) may result in a permanent loss of extensibility
37
ROM as a therapeutic exercise
planned, structured and repetitive movement of a segment within an unrestricted pattern
38
Planned
designed in advance
39
Structured
activity has an organization, pattern or parameters
40
Repetitive
activity is done more than once
41
When ROM is used as a therapeutic exercise, how should patients move within the unrestricted pattern?
only move until the point of tissue resistance and NOT beyond (that would be stretching) patients should not feel any tension, pull or stretch
42
3 types of ROM
PROM, AROM and AAROM
43
PROM
movement of a body segment within an unrestricted pattern or ROM that is produced entirely by an external force little to no muscle activity because the external force should produce all of the movement assess AFTER AROM
44
AROM
movement of a body segment within an unrestricted pattern or ROM that is produced entirely by the contraction of muscles that cross the joint assess BEFORE PROM
45
AAROM
movement of a body segment within an unrestricted pattern or ROM that is produced by both the contraction of muscles AND an external force
46
Indications of PROM
patient has a health condition where active motion might negatively affect the healing process (when acute inflammation is present or in the event of contractile tissue repair) patient is not able to actively move a body segment (not enough strength or force) patient has poor understanding of the desired movement pattern (can be used as a method of education)
47
Goals of PROM
maintain joint mobility and soft tissue extensibility maintain movement awareness minimize and prevent contractures assist blood circulation, vascular dynamics and synovial fluid movement minimize pain
48
Limitations of PROM
does not prevent muscle trophy or increase muscle strength/endurance because there is little to no muscle activity does not assist circulation as well as movements with muscle contraction (AROM or AAROM)
49
The methods of performing PROM as an intervention are based on what?
who or what provides the external force
50
Therapist or caregiver generated PROM
external force is provided by another person
51
Patient/self generated PROM
patient provides the force themselves with an uninvolved body part or via a piece of equipment
52
Gravity PROM
gravity provides the external force
53
Machine PROM
a CPM (constant passive motion) machine provides the external force
54
Indications of AROM and AAROM
patient is able to contract muscles and move the body segment with or without assistance contraction of muscles is NOT contraindicated to improve muscle performance in patients who are weak due to active muscle contraction aerobic conditioning and warm-ups relieve stress from sustained posture
55
When should AROM be used vs AAROM?
AROM: patients who are weak, but can move through the desired ROM AAROM: patients who are weak, but cannot move through the desired ROM
56
Is AROM/AAROM or PROM better for assisting vascular dynamics?
AROM/AAROM
57
Goals of AROM/AAROM
same as PROM, BUT it assists vascular dynamics better than PROM prevent thrombus formation develop motor skills and coordination prevent disuse atrophy of soft tissues due to active muscle contraction
58
Limitations of AROM/AAROM
only develops skills in the patterns used does not improve or maintain strength in muscles with normal strength
59
The methods of performing AAROM as an intervention are based on what?
who or what provides assistance
60
Therapist or caregiver assisted AAROM
therapist or caregivers assists AROM
61
Patient or self assisted AAROM
patient assists the AROM themselves
62
What is the difference between therapist/caregiver generated PROM and therapist/caregiver generated AAROM?
in AAROM, the patient is allowed actively contract their muscles and is instructed to use the involved segment as much as possible and the external force is provided as much as needed to move the limb through the desired ROM in PROM, there is NO muscle contraction and the external force produces all of the movement
63
Device AAROM
a device assists the AROM
64
When should ROM not be performed as an intervention?
if the patient is experiencing a life-threatening condition (once managed, ROM may be initiated with close monitoring) if motion would be detrimental to the healing process (protective or controlled motion might aid the healing process) if motion puts that at risk for injury or re-injury if the patient experiences muscle guarding if the patient experiences increased effusion or inflammation
65
Protective or controlled motion
minimize the physical stress applied to healing tissues by limiting the type of ROM, the specific ROM performed and the amount of ROM to protect the healing process
66
Why is complete immobilization avoided?
due to its negative effects: contractures, adhesions, decreased circulation, edema and decreased flow of synovial fluid within the joint(s), causing poor nutrition BUT after surgery, too much motion may be detrimental to the healing process (use protective and controlled motion)
67
Stretching
application of a force at the end of the available ROM causing soft tissues to elongate just beyond the point of resistance planned, structured and repetitive just like ROM
68
When is stretching prescribed by PTs?
when the restricted ROM is due to shortened tissues or when soft tissues have lost their extensibility when restricted ROM may lead to structural deformities that are preventable before/after vigorous exercise to educe muscle soreness component of fitness
69
2 types of stretching
static | dynamic
70
Static stretching
elongating tissues just beyond the point of resistance and holding this stretch for a period of time
71
Dynamic stretching
actively moving the limb just beyond the point of resistance and it is performed several times in a controlled manner
72
How does static stretching impact physical performance immediately before activity?
does not improve or may even negatively impact physical performance before activity
73
How does dynamic stretching impact physical performance immediately before activity?
may improve physical performance before activity
74
When can both static and dynamic stretching have long-term benefits on physical performance?
if they are performed on a regular basis
75
Parameters of stretching
FITT Principle volume, speed and mode
76
Frequency of stretching
number of sessions per day or per week depends on the type or severity of contracture, the cause of motion loss and the stage of healing and tissue quality
77
Intensity of stretch
amount of force applied to a tissue ORDINAL (numbers do not have real meaning, as it is related to a perception or feeling with the use of descriptors)
78
What is the difference between low intensity and high intensity stretching?
low: more effective, safe and comfortable high: more soft tissue damage and worse post-exercise soreness (more recovery time)
79
4 types of stretching
passive dynamic ballistic pre-contraction
80
Static stretching
elongating a tissue just beyond the point of resistance and holding the stretch for a period of time
81
2 types of static stretching
static-active | static-passive
82
Static-active stretching
elongating a tissue just beyond the point of resistance and holding the stretch for a period of time while the patient contracts muscles opposite to the short or stiff structures (what is being stretched)
83
Static-passive stretching
elongating a tissue just beyond the point of resistance and holding the stretch for a period of time using another body part, equipment or assistance from another person
84
Dynamic stretching
elongating a tissue just beyond the point of resistance and actively moving the body part in a controlled manner through the full ROM just beyond the point of tissue resistance at a slow velocity and then holding it for a (very) short period of time (a few seconds or less)
85
Ballistic stretching
elongating a tissue just beyond the point of resistance and then rapid, alternating movements or bouncing is performed at the end of the ROM generally NOT recommended due to the risk of injury
86
Pre-contraction stretching
contraction of the muscle being stretched followed by stretching or contraction of muscles opposite to short or stiff muscles in order promote relaxation of muscle being stretched
87
3 types of pre-contraction stretching
proprioceptive neuromuscular facilitation and inhibition techniques post-isometric relaxation post-facilitation stretch
88
Duration of stretching
time a stretch force is applied and tissues are maintained in a lengthened position
89
Short duration stretching
60 seconds
90
Long duration stretching
minutes to hours
91
Relationship between the intensity and duration of stretching
low intensity, high duration high intensity, low duration
92
Relationship between the intensity and frequency of stretching
low intensity, more frequency high intensity, less frequency (to allow for tissue healing and prevent residual muscle soreness)
93
Duration of static-passive stretching
long duration
94
Duration of static-active stretching
short duration
95
Volume of stretching
total end range (elongation) time includes the duration of stretch, number of reps and number of times per day
96
How do you increase volume?
by increasing the frequency and repetitions
97
Speed or velocity of stretching
rate at which a limb is moved or stretch force is applied
98
Slow stretch velocity
minimizes muscle activity, as less force is required to deform connective tissue less likely to active muscle spindles and the muscle stretch reflex, causing tension and resistance to stretching easier to control, making it safer (reduced risk of injury or soreness)
99
High stretch velocity
controversial (may be appropriate for highly trained individuals or high-demand athletes at the end of rehab) progression should be done slowly (static, dynamic and then ballistic)
100
3 modes of stretching
manual self-assisted mechanical
101
Manual stretching
force is applied by the therapist or caregiver at the end of the ROM
102
Self-assisted stretching
force is applied independently by the patient can be a part of either the treatment session or a HEP (home exercise program)
103
Mechanical stretching
force is applied by a device to stretch tissues
104
What are the indications of manual stretching?
when the therapist wants to determine how a patient responds to stretch intensities when optimal stabilization is needed when patient lacks the capacity to perform self-stretch either physically or cognitively
105
What is the benefit of including self-stretching in an HEP?
enables patients to maintain gains that result from interventions provided during the treatment session can increase mobility and extensibility in between sessions
106
What must we educate patients on regarding self-stretching?
appropriate technique: alignment/position, stabilization and parameters of stretching
107
When should stretching be used with caution?
patients with poor bone health patients with muscles and connective tissues that have been immobilized for an extended period of time due to poor tissue quality
108
What are the contraindications of stretching?
bony block incomplete bony union after fracture joint hypermobility (could lead to subluxation or dislocation) acute inflammation tissue trauma intense sharp pain with movement when there are shortened soft tissues needed for joint stability or functional tasks with paralysis or other neuromuscular conditions
109
Pre-stretching
warm-up to increase tissue temperature via low-intensity active exercise (walking for LE and AROM for UE) superficial heat or deep-heating physical agents can increase soft tissue extensibility and decrease stiffness in risk of complete tissue failure with stretching
110
Post-stretching
have the patient perform AROM/stretching exercises through the gained ROM ensures adequate neuromuscular control and stability as flexibility increases
111
Purpose of joint mobilizations in addition to stretching
to reduce pain and promote relaxation prior to stretching
112
Purpose of soft tissue mobilization/massage in addition to stretching
to reduce pain, promote relaxation and reduce muscle tone prior to stretching
113
Purpose of cold application in addition to stretching
given prior to stretching to patients with spasticity to reduce tone and can reduce pain, therefore increasing pain tolerance
114
What precautions should be taken when applying cold?
caution should be taken when applying cold prior to stretching, especially in the early stages of healing (cold may decrease elasticity and increase stiffness, increasing the risk of trauma during stretching)
115
How can cold be used after stretching?
cold can be applied to soft tissues in the lengthened position after stretching, which may lead to improved maintenance in tissue length and less risk for post-stretching soreness
116
Parameters for ROM
type, pattern and dosage
117
What frequency of stretching exercises can improve ROM in healthy individuals?
2-3 times per week
118
What is considered the safest form of stretch and yields the most effective changes in tissues?
low intensity, long duration stretching
