H35 ROM/Sit & Reach

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.
