  • Re: Janda Test?

    I assume that the authors are talking about Vladimir Janda's method for
    assessing muscle length (one of those tests is the Modified Thomas
    Test). Dr. Janda is a Czech medical doctor who has over the years
    asserted that much musculoskeletal pain is from, in part, a chronic
    shortening of certain muscles which cause alterations in normal muscle
    activation patterns.(1-6) The muscles prone to this
    shorenting are:

    Tibialis posterior
    Tensor fascial lata
    Rectus femoris
    Short hip adductors
    Lumbar Erector Spinae
    Quadratus Lumborum
    Pectoralis Major
    Upper Trapezius
    Levator scapula
    Flexors of upper limb

    Although I have most of what Janda has published in English there is
    supposedly much more published in Czech and German. However, I am
    unaware of any RCTs that have evaluated the effectiveness of his
    treatment approach even though it has become accepted by many members of
    the chiropractic and physical medicine professions. I am not aware of
    any studies that have investigated the and psychometric properties of
    these tests.
    At present Dr. Janda is in the U.S. conducting seminars.

    If my assumption is correct Janda takes a muscle to its end range and
    assesses the end-feel (i.e., the springiness of the muscle when one
    pushes it into the barrier of its motion). A hard end-feel would allow
    for a presumptive diagnosis of chronic muscle shortening. Janda then
    describes a method treatment that has been termed Post-Facilitation
    Stretching (PFS). PFS stretching is accomplished by having the patient
    contract the muscle in question against resistence with a maximum effort
    for about 10 sec. Then the muscle is stretched ballistically and held
    in the new stretch position for 10 sec. This process is repeated a few
    times per treatment session. Such treatment in my experience often
    results is an obvious change in the end-feel and an sustainable increase
    in range of motion.
