Which tool functions as an angle detector______________________?
Show answer Hide answer
Answer: C. Electrogoniometer
Explanation
An electrogoniometer is a specialized electronic instrument utilized to measure joint angles dynamically. It records continuous angular changes during movement and transmits the data to a computer. Biomechanists rely on this precise tool to analyze human joint kinematics during physical activity. Goniometers measure the range of motion around joints in clinical and research settings. Electronic versions provide real time kinematic data superior to traditional manual plastic goniometers. Sensors are strapped securely across joint axes to track flexion extension and rotational angles.
Physical therapists use electrogoniometers to track patient rehabilitation progress following joint surgery. Ergonomics researchers evaluate workplace movements using joint angle sensors to prevent repetitive injuries. Sports scientists analyze athletic running mechanics by monitoring knee and hip angles continuously. Option A names a dynamometer which measures muscular force and grip strength rather than angles. Option B suggests a spirometer which assesses pulmonary respiratory function instead of joint motion. Option D mentions none of these which is incorrect because electrogoniometer is the right tool.
