Range of Motion (ROM) ROM is the angular displacement of a joint from one extreme of movement to the other. It is a measure of the flexibility of a joint ROM is affected by: shape of the articular surfaces restraining effect of ligaments controlling action of muscles both contractile ability and tightness of muscles (length) bulkiness of muscle in the way fat tissue in the way joint adhesions - scar tissue pain ROM can be measured using: Goniometer this is a long-armed protractor centered on the fulcrum of the joint with long arms aligned with the mechanical axes of the bones

Protractor measure joint angles from pictures of the movement Leighton Flexometer a device to measure ROM when it is difficult to use a goniometer. See the diagram above. Electrogoniometer also called an "elgon" this is simply a goniometer with an electrical device called a potentiometer at its fulcrum for electronic measurement of ROM Take a motion picture film or video and trace the body segments in successive

Unformatted text preview: frames on sheets of paper. Measuring with a protractor in one tracing and subtracting it from the next tracing will enable measurement of ROM. The film is taken with the joint/segment action occurring in a plane perpendicular to the line of view of the camera. Increasing Range of Motion Use force judiciously to stretch the restrictive tissue can be passive - force externally applied can be active - force applied by self can be ballistic - rhythmic movement produces rebound stretch can be static - body part held with muscle in lengthened position Static, active stretching is: the safest - less chance of over stretching and: there is less antagonistic muscle activity because of use of reciprocal innervation Ballistic stretching is counterproductive activates the muscle spindle stretch reflex - this causes reciprocal innervation (contraction) of the very musculature you are trying to stretch...
