Measuring hip joint angle with an electrogoniometer in conjunction with the standard sit-and-reach test, the straight leg flexion test, and visual observation may allow an examiner to more effectively assess the flexibility of the individual.
To measure hamstring and back flexibility using a standard sit-and-reach test and determine whether the measures fall within accepted normative ranges.
To measure hip joint range of motion and hamstring flexibility through the use of an electrogoniometer DURING the sit-and-reach test.
To measure hip joint range of motion and hamstring flexibility, performing a supine straight-leg raise (passive or active), through the use of an electrogoniometer and compare to normative values.
Have a lab partner perform visual comparisons of the range of motion of the hip joint during each of the three activities and record the observations.
Tasks Performed by the Student
sit on the floor with feet up against the sit-and-reach box and legs next to one another
lean forward with one hand over the other and slowly reach forward as far as possible, three times, holding the position on the third reach for at least 2 seconds
slowly lift one leg (side with the goniometer), keeping the other leg flat on the floor
keep both legs straight
continue to the endpoint and then hold for several seconds
slowly lower the leg to the floor
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.

The STMEPM Programmable Stimulation System for E-Prime allows a user to interface the STMISOLA Stimulator with E-Prime to control the stimulus frequency and stimulus intensity for real-time stimulus delivery changes based on a subject’s responses. It is also possible to hardcode the stimulus intensity levels in the presentation so that predefined stimulus levels are delivered […]
The new issue of Psychophysiology has a study “Quantifying rapid changes in cardiovascular state with a moving ensemble average” using MEAP for preprocessing/analysis and BIOPAC hardware and software for data collection, display, and storage. The proof of concept study demonstrates a viable method for the adoption of ICG measures across the field of psychophysiology. MEAP (moving ensemble […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering MRI, ECG, and Laser Doppler Flow measurement. fMRI & Thermal Perception: The neural mechanisms underlying thermal perception (how hot or cold we perceive the temperature to be) have not been fully […]
