The different grades of the Risser sign give a measure of bone maturity and thus of the skeletal growth to be expected.

The Borg Scale is a method to measure a personâs perceived exertion rate. Developed by Stockholm University professor Gunnar Borg during the 1980s, the scale does not require any equipment, but asks participants who engage in physical activity to assess his or her perceived rate of exertion from light to strenuous. The scale measures exertion in a range between six and 20.
