Types of Goniometers
A universal goniometer is a basic equipment.
It is usually made of clear plastic, sometimes metal, and some cost just a few dollars.
It is an indicator of flexibility as one ages.
Repeat use of a goniometer can help measure your improvement.
Increased (or preserved) range of motion means better mobility and injury prevention long term.
Summary
Ask your physical therapist how goniometric measurements figure into your overall rehab program and assessment.
Your PT should take both quantity and quality motion into account when assessing your condition.
