Sample Outline: Cryotherapy

Cryotherapy- therapeutic application of cold

Cryokinetics- used of cold in therapeutic exercise

Modes of Transmission of Cold Therapy

1.Conduction – commonly used

Factors affecting magnitude change:

*temperature gradient differences between the cold and the tissue

*time and pressure

*thermal conductivity of the area being cooled

*type of cooling agent

2. Convection – least common, not practical to use

3. Evaporation – consist of highly volatile liquids that evaporate rapidly in contact with warm objects

Physiologic Effects of Cold

1. Increase blood viscosity

2. Vasoconstriction

3. Decrease metabolism thus decrease metabolic by products and decrease leukocytic phagocytic action which lead to retardation of healing

4. Decrease blood flow thus decrease bleeding and decrease removal of metabolites

Biophysical Effects

1. Hemodynamic Effects

-Quick icing can lead to cutaneous vasoconstriction

-Prolonged icing can lead to shivering and the Hunting Response of Lewis (5-10 deg C)

Causes:

a. Direct action of cold on smooth muscle of blood vessels

b. Reflex cutaneous of anterior hypothalamus as cooled blood returns, more vasoconstriction; in general, shivering and increased metabolic occurs

2. Decreased in Blood Flow

Causes:

a. Vasoconstriction

b. Increase in blood viscosity

c. Decrease production of metabolites

d. Effects of on post traumatic edema and inflammation

*less fluid filtration into the interstitium

*less inflammation and less pain

*decrease in metabolic rate

e. effects on peripheral nerve- decrease in motor and sensory nerve conduction velocity

* sensory- type A> type C

* motor- A gamma blocked before A alpha

f. effects on muscle strength

* increase in mm strength in quick icing

*decrease in mm strength in prolonged icing

g. neuromuscular effects

*transient reduction in spasticity

(note: some books say it can decrease but some researches imply that it can also increase)

Sample Outline: Electromyography Biofeedback (EMG)

Biofeedback- nearly instantaneous return of information to a person about physiologic functions of which he or she might otherwise be unaware of

- Technique using equipment to reveal to some human beings some of their internal physiologic events in the form of visual and auditory signals to teach them to manipulate these involuntary or unfelt events by manipulating the displayed signals

Types of Biofeedback:

1. Thermobiofeedback

2. Galvanic Skin Response Biofeedback

3. HR/ Blood Volume

4. Pressure Feedback

5. EMG Feedback

6. Position Biofeedback

7. Sphincter Control Training

8. Respiratory Biofeedback

9. Feedback Goniometer

Biofeedback can assist the rehabilitation process in the following ways:

1. Enable the patient to identify the faults in the body mechanics by themselves

2. Enable the patient to try gradual correction of abnormalities based on received information

3. Provide a clear treatment goal to be accomplished by the patient

4. Allows the PT and pt to experiment the possible movement strategies

5. Helps reinforcing the appropriate motor behavior

Electromyography (EMG)

-Recording of the electrical activity generated in a muscle for diagnostic purposes

-Recording and study the electrical activity of the muscle

Types of EMG

*Clinical EMG- diagnosis

*Kinesiologic – for research and rehab

Concept Use: Motor Unit Action Potential

Uses of EMG as biofeedback:

1. Help the patient to regain the function of muscle that may have been lost or forgotten following an injury

2. Measures electrical activity of muscle not muscle contraction

3. Do not directly measure the muscle contraction, measure only the electrical activity associated with a muscle

4. Patient should understand that the electrical activity implies information about the quality of the muscle contraction but does not measure the strength of that muscle contraction specifically

Principles of Biofeedback

1. Middaugh’s Conceptual Framework

· PT evaluates the patient, sets parameters in the instrument, plans the strategies and provides the px instructions about the strategies to be followed

· Patient follows the strategies, the biofeedback system records the parameter, display the information before the patient

· Patient in turn tries to perform movement strategies alter the biofeedback signal, altering the physiological changes, producing therapeutic benefits

2. It obeys the theories of motor learning and motor control

3. It makes use of two types of feedbacks:

· Intrinsic – body’s internal feedback mechanism (visual, auditory vestibular proprioceptive)

· Extrinsic- derived from external sources (PT comments, biofeedback devices)

General Uses of Biofeedback in Physical Therapy:

1. To correct disorder

· In px with hemiplegia and CP, use to control spasticity and muscle re-education

· Use to dystonic px to reduce uncontrolled movement and posture

· In postural disorder to correct abnormal posture

· In functional breathing disorder such as hyperventilation and shallow breathing

2. To improve balance control

· Standing/balance training with force plate connected to a visual display in patient with hemiplegia and paraplegia

3. To control incontinence

· Use a balloon like device in the rectum

4. To control stress in stress induced disorders

· Beneficial in inducing relaxation in tx of stress disorders

5. Training walking pattern (gait)

· Use in monitoring weight bearing through the use of pressure sensitive pad in the shoe

· Re educate muscle groups in different phases of gait

6. Conditions in which control over some defective muscle movement is attempted

EMG Biofeedback in PT:

1. Motor retraining

2. Spasticity reduction

3. General relaxation training

Components of EMG Biofeedback

1. EMG Signal – gives measure of motor unit action potential of a muscle because it is hard to quantify, it is altered to be more meaningful to px and PT

2. Equipment- basic units have one channel, 2 channels used to monitor muscle simultaneously

3. Electrodes- General Rule : 2 active or recording electrodes/ one reference electrode

Presentation of EMG Signals

1. Visual Display

- Fluctuating needle meter read

- Flashing numbers

- A series of progressively lit lights

- Oscilloscope or computer screen

2. Auditory Feedback

- either threshold or proportional type

Threshold mode- turning a tone on or off when EMG amplitude reaches a level predertermined by PT

Proportional mode- produces a sound that modulated proportionally to EMG amplitude

Techniques of Application

1. Before using EMG biofeedback, PT should be familiar with motor unit activation and device used

2. Test Machine

3. Before attaching, clean electrodes and skill with alcohol to remove dirts and oils

4. Skin hair may have to be shaved to reduce electrical impedance

5. Give rationale

6. Patient should understand that the machine will not help to cause the mm contraction but simply monitor the mm activity

Clinical Application

1. Mm relexation vs Mm recruitment

2. Criteria for best candidates for EMG-BF training:

- Potential voluntary control must exist

- Motivation and cooperation are essential

- Inability to follow commands

Specific Considerations

· Progression of training

· Types o mm contraction

· Joint segment training

Contraindications:

· Neglect

· Severe Aphasia

· Visual or Hearing problems

· Complete paralysis

· Severe sensory deficits

· Proprioception loss
