Goniometry Question

[KiranC]

Difference in active and passive is not always related with musculoskeltal problem because it is present in normal fit human being also.Normally passive range is more than active range because each joint has a small amount of motion available that is not under the voluntary control. The additional passive range that is available at the end of normal active range is due to stretch of tissues surrounding the joint & reduced bulk of relaxed muscles.
This additional passive range helps to protect the joint structures because it allows the joint to absorb extrintic forces.

I hope you find this information useful and I want more information about passive range of motion, please let me know.
