H35 ROM/Sit & Reach

View Cart “Adhesive Tapes” has been added to your cart.

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.

Experimental Objectives

  1. To measure hamstring and back flexibility using a standard sit-and-reach test and determine whether the measures fall within accepted normative ranges.
  2. To measure hip joint range of motion and hamstring flexibility through the use of an electrogoniometer DURING the sit-and-reach test.
  3. 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.
  4. 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.

fNIRS Data Analysis

In this fNIRS training, you will see a typical analysis workflow for fNIRS data in experiments featuring both event-based and continuous stimulation. Learn about a powerful yet easy-to-use software package with both a graphical user interface and scripting capability (for automation).

What You Will Learn:
• Preparing data for analysis
• Signal conditioning, noise removal, and managing artifacts
• Best practices for visualizing recorded data
• Block analysis using event markers and/or time
• Further temporal and spatial processing of data, including cell-by-cell processing
• Automation of analysis procedures
• Performing common statistical comparisons (t-test, ANOVA)
• Spatial visualization
