What are the modern origins of therapeutic exercise? ***
- Sweden in the 19th century with Pehr Henri Ling (a fencing instructor) who believed precise movements, scientifically applied, could remedy disease and dysfunction of the body

- Switzerland, in 1902 when Frenkel published an exercise program for ataxia; his main contribution was insistence on repetition

Macrotrauma
a single injurious force in which the pain and tissue destruction occur simultaneously
Microtrauma
a series of small injurious forces, many/most/all of which precede the patient's perception of pain
Is pain always an accurate indicator of tissue health?
No, since the chemical mediators which relay pain may dissipate long before the tissue is healthy enough to respond to the forces such as those that led to the initial injury.
Describe Phase I of tissue healing. ***
- inflammatory response
- lasts 24-48 hours, up to 7-10 days
- vasoconstriction (clot), then vasodilation (bring in WBC, etc.)
- edema, pain, redness, increased temperature, loss of function
Describe Phase II of tissue healing. ***
- repair/proliferation phase
- 48 hours to 6 weeks after injury
- tissue regeneration, vascularization, cell growth
- initially lays down Type III collagen, which is weak and thin, but exists as a foundation for further replacement with Type I collagen
- revascularization
- epithelialization - new skin/mucous/serous membranes
Describe Phase III of tissue healing. ***
- connective tissue formation/remodeling phase
- 3 weeks to 12 months after injury

Definition of therapeutic exercise ***
the systematic performance or execution of planned physical movements, postures, or activities intended to enable the patient/client to:

1) remediate or prevent impairments
2) enhance function
3) reduce risk
4) optimize overall health
5) enhance fitness and well being

(A secondary definition by Licht states that therapeutic exercise is "motions of the body or its parts to relieve symptoms or to improve function.")

The inability of a joint to move through a full ROM due to loss of elastic extensibility of the connective tissue components is known as:
passive insufficiency

(ex. women who only wear heels shorten their gastrocs and Achilles)
What could decreased ROM, reduced strength, or increased pain despite the stage of healing indicate? What should the response be?
possibly the intervention on one soft tissue exacerbating the symptoms of another, since rarely is only one soft tissue affected

response should be to decrease the load and/or increase amount of rest (work with the PT on POC)
Use of physical agents or electrotherapeutic modalities in the absence of other interventions is not considered:
physical therapy

(unless documentation justifies necessity of exclusive use)

Qualify a "normal" (5/N) grade in manual muscle testing ***
patient completes full ROM against gravity; holds against maximal resistance
Qualify a "good" (4/G) grade in manual muscle testing ***
patient completes full ROM against gravity, holds against strong resistance, but yields against maximum resistance
Qualify a "fair" (3/F) grade in MMT ***
patient completes full ROM against gravity with no manual resistance

(This is the starting point--test a 3, then try 4/5, because you obviously don't want to start with moderate or maximum resistance on someone who cannot even perform the full movement in the first place.)
Qualify a "poor" (2/P) grade in MMT ***
patient either:

- completes full ROM with gravity minimized (e.g., elbow supported on a table—partial would be a 2-/P-),

- or completes partial ROM against gravity

(gravity minimized is the more correct/better way of testing this level)

5% - T
0% - Z
What considerations must be made when applying resistance during MMT? ***
you need to be able to adjust based on the patient's:
- age
- gender
- muscle group being tested
[e.g., less force (about 2-3 fingers) used for resistance on external shoulder rotation because only the small infraspinatus and teres minor are prime movers; more force/whole hand for internal shoulder rotation because larger latissumus dorsi, pectoralis major, subscapularis, and teres major are prime movers]
How is it recorded if the patient lacks full ROM? ***
e.g., -20/G

(ask for clarification/explanation on this!!)
The therapist performing MMT must be sure to compare...
***
both sides of the body
What is important to remember about your hands when performing MMT? ***
BOTH hands are doing something at all times!!

provide stabilization to the proximal segment while adding resistance to distal segment

(for skills check this also got a foot stomp!!)
While providing support to the proximal segment, the therapist is also watching for/trying to prevent...
substitutions by other muscles

[e.g., on shoulder external rotation for a patient with grade 2 or less (patient lying prone with arm dangling for g.m.) second hand is palpating the infraspinatus/teres minor to ensure there is shoulder movement/rotation and the patient is not simply supinating the forearm)
The book's definition of ROM
the extent of osteokinematic motion available for movement activities, functional or otherwise, with or without assistance
How is gravity's affect on ROM controlled?
through positioning of the body segment during the movement

What intrinsic factors affect ROM?
- anatomic composition of the joint
- shape and congruency of the articulating bony surfaces
- pliability of the joint capsule, ligaments, and other collagenous tissues
- strength and flexibility of musculature acting on or crossing the joint

(one or more of these factors create anatomic limits to joint ROM)
What extrinsic factors affect ROM?
- age (causes decreased pliability in contractile and noncontractile tissues, thus reduced ROM)
- body segment size (related to muscle or adipose tissue bulk)
- effects of disease, injury, overuse, and/or immobilization
Upon what does hyaline cartilage nutrition depend?
on the compression and decompression that accompanies joint movement
Often, disease and traumatic injuries alter the _______ of the joint and this leads to....
biomechanics

Articular cartilage, due to its avascular state, can undergo irreversible degeneration with immobility of how long?
even short periods (i.e., days)
Why do collagenous tissues (ligaments, joint capsules, fascia, and tendons) experience tightening and stiffening during immobilization?
primarily due to the formation of excessive collagen fiber crosslinks that reduce joint motion and mechanical strength of connective tissue
What changes in muscle tissue are seen with immobilization? How rapidly can this occur?
reduction in muscle tissue size and contractile force (both strength and endurance)

after just a few days of immobilization
Which muscle tissues atrophy more quickly, fast-twitch or slow-twitch?
slow-twitch
The amount of muscle tissue contracture (adaptive shortening) is dependent on...
the positioning during immobilization (different effects on the sarcomere length and number depending on whether the muscle is immobilized in a shortened or lengthened position)
Book definition of ROM exercise
