17
Administering Thermotherapy (cont.)
Moist heat applications Hot soak Hot compress Hot pack Paraffin bath Diathermy – high-frequency wave achieves deep heat penetration Ultrasound Shortwave Microwave
18
Apply Your Knowledge Correct!
What is the main difference in the effect of cryotherapy and thermotherapy that results in the physiologic response of each? ANSWER: Cryotherapy causes blood vessels to constrict, resulting in its physiologic effects, while thermotherapy causes blood vessels to dilate. Correct!
19
Hydrotherapy Use of water to treat physical problems Whirlpools
Water is agitated by jets of air under pressure Generates hydromassage Relaxes muscles Increases circulation Also used to clean and debride wounds, ulcers, and burns
20
Hydrotherapy (cont.) Contrast baths Underwater exercises
2 baths, one hot and one cold Patient moves quickly from one to the other Purpose Induces relaxation Improves circulation Greater mobility Underwater exercises Warm swimming pool Buoyancy takes pressure off joints Purpose Promotes relaxation Increases circulation
21
Apply Your Knowledge Super! What are the main effects of hydrotherapy?
ANSWER: Hydrotherapy relaxes muscles, increases circulation, and improves flexibility and mobility. Super!
22
Exercise Therapy Preventive and therapeutic benefits
Flexibility Mobility Muscle tone Strength Primary treatment for fractures, arthritis, and some respiratory diseases Minimizes symptoms Slows disease progression
23
Exercise Therapy (cont.)
Improves muscle tone and strength Maintains ROM Prevents or corrects physical deformities Promotes neuromuscular coordination Improves circulation Relieves stress Lowers cholesterol levels Aids in resumption of normal daily activities
24
Medical Assistant’s Role
Provide patient information Types of exercise programs Treatment plan Provide support and encouragement Assist with ROM exercises Teach the patient and family about ROM exercises.
25
Types of Exercise Choice based on patient’s physical condition
Active mobility Self-directed exercises Increase muscle strength and function Passive mobility Therapist or machine moves the patient’s body part Retain ROM and improve circulation Aided mobility Self-directed with assistance of a device such as exercise machine Retain or improve ROM
26
Types of Exercise (cont.)
Active resistance Works against resistance Increases muscle strength Isometric Patient relaxes and then contracts muscles while in a fixed position Maintains muscle strength if immobilized ROM exercises Move each joint through its full range of motions Improves flexibility and mobility Improves circulation and muscle function
27
Electrical Stimulation
Delivers a controlled amounts of low-voltage electric current to motor and sensory nerves Stimulates muscle Prevents atrophy Helps in healing injured joints Retrains a patient to use injured muscles
28

29
Traction The pulling or stretching of the musculoskeletal system Uses
Used to treat fractured bones and dislocation, arthritic, or other diseased joints Uses Create and maintain bone alignment Reduce and prevent joint stiffening Correct deformities Reduce and relieve muscle spasms
30
Traction (cont.) Manual Static
Stretching muscles and separating joints by gently pulling on them Improves motion and decreases stiffening Uses Muscle spasms Stiffness Arthritis Static Weight traction using harness and weights Used to relieve muscle spasms
31
Traction (cont.) Skeletal Mechanical Long-term/heavy weights
Pins, wires, or tongs surgically placed Pulleys and weights provide continuous traction Mechanical Device intermittently pulls and relaxes Promotes relaxation
32

Canes Standard Tripod (3 legs) and quad-base (4 legs)
Patient who needs only small amount of support Tripod (3 legs) and quad-base (4 legs) Create wide base of support More stable than standard canes Must be adjusted to correct height for patient
35
Walkers Used by older patients with Provides a sense of stability
Difficulty walking unassisted Balance problems Provides a sense of stability Types – Table 11-2 Adjust to proper height for patient
36
Crutches Transfers weight to the arms Types Axillary
Ground to axilla Short-term use Lofstrand, or Canadian Ground to forearm Long-term use
37
Crutches (cont.) Complications may arise if not measured properly
Pressure on nerves in axilla Strain on back, imbalance Measuring for crutches Should be 2 to 3 finger-widths between supports and axilla 30º flexion at elbow
38
Crutches (cont.) Crutch gaits
Four-point – slow gait for a patient who can bear weight on both legs Three-point – used when patient cannot bear weight on one leg Two-point – used when patient can have some weight on both legs; must have good muscle coordination and balance Swing gait – used when patient has severe disabilities
