Updated DATE BSL PRO Lesson H35: Range of Motion/Sit and Reach Lesson developed by: Heather Medema-Johnson, M.S, ATC, CSCS Introduction A well-rounded physical activity program is an integral part of a strong, overall health, wellness, and fitness program. Flexibility is a major component of a well-rounded physical activity program and is defined as the ability of a joint (or group of joints) to move through its full range of motion . Good flexibility can prove to be beneficial for the musculoskeletal system. It may prevent injuries and soreness, improve body position and alignment/posture, and improve performance in sports and other activities. Because of the importance of flexibility, fitness and sports medicine professionals typically assess an individuals’ level of flexibility before prescribing an exercise, sports training, or physical rehabilitation program. Flexibility is joint specific, so there are no tests of overall general flexibility for an individual. Instead, static flexibility tests are used, which are based on linear and angular measures of the motion of a joint or group of joints. Static measures are widely accepted as a common clinical method of measuring flexibility and range of motion about a joint through the use of traditional goniometers and inclinometers. Commonly accepted field tests of static flexibility include, among others, the sit and reach test , which evaluates combined flexibility of the lower back and hips, and the supine straight leg flexion test, which evaluates hamstring and hip flexor flexibility. Normative data values have been established, which aid the examiner in assessing an individual’s level flexibility and ROM at a specific joint. Traditional sit and reach test scores and traditional goniometry measures of the hip are difficult to record throughout the range of motion. These traditional measures are only most effective at the beginning and end of the motion. In addition, it is difficult to quantify very small changes or improvements in flexibility with a sit and reach test alone. The BIOPAC electrogoniometer, however, provides a more effective method of overcoming these limitations – it provides a means of looking at joint angle of the hip throughout the entire range of motion, and it detects very small changes in the motion, as measured in degrees. 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. An examiner using these combined measures may be able to more accurately
