What does the symmetry index compare in rehab?

Explanation:
The idea being tested is bilateral symmetry in rehab. The symmetry index is used to compare how the two limbs perform relative to each other, focusing on functional outputs like strength and range of motion. By looking at measures such as peak strength (or torque) and ROM in both sides, you get a percentage that shows how close the injured side is to the healthy side. A higher percentage indicates better symmetry and progress toward full recovery, guiding how you advance loading and exercises. It isn’t about lung capacity, heart rate, or pain levels at rest, which are separate recovery metrics.
