Range of Motion: Ankle Inversion
Jun 28, 2023An inclinometer is a device used to measure the angle of a joint. To test ankle inversion range of motion using an inclinometer, follow these steps:
- With their shoes and socks off, get your client to lie down in a supine position on a massage table.
- As this is a rotational test, the Measurz inclinometer will adopt its transverse plane feature. Thus, it is critical that the smart device is aligned correctly before proceeding with this protocol.
- While performing this test, the practitioner should assist the client by holding their lower leg down on the table. Doing this will allow the tibia to remain in a fixed position and therefore the ankle joint can be truly isolated.
- Once set, place the smart device in line with the second metatarsal, ensuring the Measurz inclinometer is set at 0 degrees.
- Instruct the client to rotate their foot in toward their midline. Using the inclinometer, follow the client’s foot until they have achieved their maximal rotation.
- Hit the pause, and then the save button to record and view the results. NB: Aiming for a score of at least 30 degrees of ankle inversion.
The normal range of motion for ankle inversion can vary depending on a person's age, gender, and physical activity level. However, on average, the normal range of ankle inversion range of motion is around 20-30 degrees.
