    Study Notes

    Measuring Range of Motion and Flexibility Testing

    • Electrogoniometers have advantages over traditional goniometers and digital goniometers, such as flexibility and hands-free use.
    • Leighton Flexometer is a device used to measure range of motion (ROM) at the elbow joint using a weighted 360-degree dial and pointer.
    • Inclinometers, another gravity-dependent goniometer, are easier to use and do not require alignment with specific bony landmarks.
    • Validity and reliability of direct measures of ROM are highly dependent on the joint being measured and technician skill.
    • Radiography is considered the best reference method for establishing the validity of goniometric measurements.
    • Upper extremity joint measurements are generally more reliable than lower extremity joint measurements.
    • Inclination measurements have variable intertester reliability, with lumbar extension and subtalar joint showing different reliability coefficients.
    • The sit-and-reach test is included in most health-related fitness test batteries due to the belief that lack of flexibility is associated with low back pain and musculoskeletal injuries.
    • The sit-and-reach test provides an indirect, linear measurement of the ROM and is used to evaluate the static flexibility of the lower back and hamstring muscles.
    • Research indicates that the sit-and-reach test is not a valid measure of low back and hamstring flexibility and is unrelated to self-reported back pain.
    • The CSEP sit-and-reach test protocol involves a warm-up, specific measurement instructions, and a health benefit rating based on age and performance.
    • Different types of sit-and-reach tests and equipment are available, including modified versions to account for limb-length differences and discomfort during testing.

    Flexibility and Joint Range of Motion in Exercise Science (EXCI 252)

    • Static flexibility measures the total range of motion (ROM) at a joint and is limited by the extensibility of the musculotendinous unit.
    • Dynamic flexibility measures the rate of torque developed during stretching throughout the ROM.
    • Joint range of motion depends on morphological factors such as joint geometry, joint capsule, ligaments, tendons, and muscles.
    • Joint classification is based on structure and function, including gliding, hinge, pivot, condyloid & saddle, and ball & socket joints.
    • Soft tissue structures that limit flexibility include joint capsule, muscle & its fascia, tendons & ligaments, and skin.
    • The muscle-tendon unit affects both static and dynamic flexibility and is influenced by viscoelastic properties and muscular contraction.
    • Elastic and viscous deformation of the muscle-tendon unit occur during stretching, affecting tension and muscle stiffness.
    • Factors affecting flexibility include body type, age, gender, physical activity level, warm-up, and amount of stretching & flexibility training.
    • Bodybuilders and obese individuals may score poorly on ROM tests due to large hypertrophied muscles or excessive subcutaneous fat.
    • Age-related flexibility loss is attributed to increased muscle stiffness, lower stretch tolerance, decline in physical activity, and development of arthritic conditions.
    • Females are generally more flexible than males, attributed to gender differences in pelvic structure and hormones affecting connective tissue laxity.
    • Habitual movement patterns, lack of physical activity, disuse, and warm-up are important determinants of flexibility, affecting ROM and muscle tissue.
