Document Summary

Then you gain velocity, but in the opposite direction going down. Need proper data collection techniques because they give us more precise information than viewing it with the eye. Function: manual: measure passive range of motion. Function: electro: measure active range of motion. Pros: inexpensive, instant output no delay/lag time, planar motion. Cons: only relative angles, may move, constraining. Measure of the electrical signal associated with neuromuscular activation of muscle. Provides temporal aspect of muscle firing: electonic impulses moving over muscle. Does not provide a measure of muscle strength. Cannot distinguish concentric from eccentric without accompanying kinematical data. Many cables associated with one system although telemetry is helping. Cons: large & lots of wires makes it difficult to record data during activity. Measuring the amount of force per unit of area. Pros: real time feedback, easy to use, full pressure map. Cons: can be affected by shoe type, units are not in force, affected by heat can effect data.
