IB Biology: B3.3-Measuring Joint Angles Using Computer Analysis

How can computer analysis be used to measure joint angles?

• By measuring only the muscle contraction strength and inferring the angle indirectly.

• By visually estimating the angle during motion without any electronic equipment.

• By recording movement with cameras or sensors and using software to calculate the angle between adjacent body segments.

• By applying a constant electrical current across the joint to detect angular displacement.
