This PROLesson describes basic reflex exercises and details hardware and software setup of the BSL Lessons System to record the reflex reaction. All data collection and analysis is done via the BIOPAC MP30 data acquisition unit and the Biopac Student Lab Lessons software.
EXPERIMENTAL OBJECTIVES
To measure reflex time of different nerves in the body under different conditions using the reflex hammer.
To compare and correlate magnitude of hammer strike to magnitude of response (via EMG activity).
Optional: To measure response via angular movement (goniometer) under varying strike force.
TASKS PERFORMED BY THE STUDENT
Subject will undergo the following tests:
ankle jerk relex,
knee jerk reflex,
knee jerk reflex - with Jendrassik Maneuver,
knee jerk reflex - with mental distraction,
flexor withdrawal reflex, and
voluntary knee jerk reflex
KEY FEATURES
Add event markers throughout the recording.
The software automates the calibration procedure for the student. There are no knobs and dials to confuse the student.
Graph template files ensure consistent setup for subsequent Subjects or repeated trials—plus, you can easily add your own lesson plan to the onscreen journal.
The lesson will also work as part of a group study.
