Goniometer is used for :
**Core Concept**
A goniometer is a medical instrument used to measure the angle of movement or the range of motion in a patient's joints. It is a crucial tool in physical medicine and rehabilitation, as well as in orthopedic and sports medicine. The goniometer helps healthcare professionals assess joint mobility, detect any limitations or restrictions, and monitor progress in patients undergoing physical therapy.
**Why the Correct Answer is Right**
The goniometer is specifically designed to measure the angle of movement in degrees, allowing healthcare professionals to accurately assess joint mobility. This is particularly important in patients with joint injuries, arthritis, or other conditions that affect joint movement. By using a goniometer, healthcare professionals can detect even small changes in joint mobility, which can help them develop effective treatment plans and monitor patient progress.
**Why Each Wrong Option is Incorrect**
* **Option A:** A goniometer is not used to measure blood pressure, which is typically measured using a sphygmomanometer.
* **Option B:** A goniometer is not used to measure the depth of a wound, which is typically measured using a ruler or a depth gauge.
* **Option C:** A goniometer is not used to measure the temperature of a patient, which is typically measured using a thermometer.
**Clinical Pearl / High-Yield Fact**
When using a goniometer, it's essential to ensure that the instrument is properly calibrated and that the patient's joint is in a neutral position before taking measurements. This will help ensure accurate and reliable results.
**Correct Answer: C.
