Summary
The ThermaCare Knee Wrap significantly increases temperature in the vastus medialis oblique (VMO), knee joint capsule (KJC), and skin. This portable heat therapy is effective for pain relief when intramuscular and intracapsular heating is needed.
Area of Science:
- Orthopedics
- Sports Medicine
- Physical Therapy
Background:
- Knee pain affects active individuals and the elderly.
- Heat therapy is commonly used for pain relief.
- Existing heat modalities lack portability.
Purpose of the Study:
- To evaluate the effectiveness of the portable ThermaCare HeatWrap for the knee.
- To determine if the heat wrap increases knee joint temperature.
Main Methods:
- A 2x5 factorial design compared heat wrap vs. control over two hours.
- Volunteer subjects had muscle (VMO) and intracapsular knee joint (KJC) temperatures measured.
- Skin temperature and heat perception (VAS) were also recorded.
Main Results:
- The heat wrap increased VMO temperature by 3.19°C, KJC by 2.62°C, and skin by 7.48°C.
- The control group showed a slight decrease in all measured temperatures.
- Subjective ratings indicated increased warmth with longer wrap duration.
Conclusions:
- The ThermaCare Knee Wrap effectively increases VMO, KJC, and skin temperatures.
- This portable heat wrap offers a viable option for conditions requiring intramuscular and intracapsular heating.
- The findings support its use for pain relief in knee conditions.

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:14Assessing Body Temperature - Axilla
Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

01:27Assessing Body Temperature - Rectal
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...
