4. Not Zeroing the Goniometer
Earlier than taking a measurement, at all times zero the goniometer. This ensures that the place to begin is correct, stopping errors.
5. Misreading the Scale
Learn the angle measurement fastidiously to keep away from errors. Double-check the studying to make sure accuracy.
6. Extreme Delicate Tissue
If the particular person has extreme comfortable tissue round their knee joint, it might probably make it troublesome to precisely place the goniometer. In such instances, a modified measurement approach utilizing landmarks just like the patella and lateral malleolus could also be essential.
| Measurement Approach | Description |
|---|---|
