A primary reduction in growth would only be expected if the injury affected the whole of the plate, which is extremely rare. The healing of shaft fractures in a shortened po- sition leads to leg lengthening rather than shortening because the growth stimulation resulting from the re- modeling process overcompensates for the shortening. Of the congenital forms, a hemihypertrophy is more common than hemihypotrophy. Hemihypertrophies occur in the Klippel-Trenaunay-Weber syndrome, Pro- teus syndrome ( Chapter 4.

RESPONDENT THERAPY Background and Description Diverse pain management strategies deriving from the respondent formula- tion of pain are commonly used to treat chronic pain generic atrovent 20 mcg on line, such as progressive muscle relaxation and biofeedback buy atrovent 20mcg lowest price. The rationale identifies the pain–ten- 276 HADJISTAVROPOULOS AND WILLIAMS sion cycle as contributing to the pain experience buy discount atrovent 20 mcg online, and thus reduction of muscle tension is the characteristic goal of treatment (Linton purchase atrovent 20 mcg amex, 1982) discount atrovent 20 mcg free shipping. Central to this view is that pain elicits a response of increased muscle tension discount atrovent 20mcg with mastercard, which itself produces more pain, and contributes directly to secondary problems such as sleep disturbance, immobilization, and depression (Lin- ton, 1982). Therapy includes educating patients regarding the association between tension and pain, and learning to replace muscle tension with an incompatible response, namely, relaxation (Turk & Flor, 1984). Relaxation therapy involves teaching patients to achieve a physiological sense of relaxation. Beyond physically reducing muscle tension, and thus pain, relaxation can have other aims, including anxiety reduction, assisting with sleep disturbance and fatigue, increasing well-being, and perhaps most importantly improving a sense of control. Progressive muscle relaxation is undoubtedly the most common form of relaxation training, and involves systematically tensing and the relaxing major muscle groups throughout the body (Turner & Chapman, 1982b). Biofeedback also involves relaxation of muscles, but is achieved through monitoring bodily responses, typically through a computer or apparatus, and providing patients visual or auditory feedback about their physiologi- cal responding. With intense scrutiny and examination, it is hoped that the patient will be able to learn how to control certain physiological responses related to pain (Arena & Blanchard, 1996). Many forms of biofeedback exist, but electromyographic (EMG) feedback, aimed to reduce muscle tension, is by far the most common with chronic pain patients. The focus has also largely been on headaches, although other conditions such as low back pain (Arena & Blanchard, 1996; van Tulder et al. At times, relaxation and biofeedback strategies are used on their own, but most commonly they are used in combination with each other as well as with the other treatment approaches described in this chapter. The ex- ception to this is with headache sufferers where biofeedback and relaxation are not infrequently used as sole treatment strategies (Arena & Blanchard, 1996). Treatment is most often offered on an outpatient basis in a group or individual format (Blanchard, 1992). These techniques help the patient to recognize and alter pain behavior patterns. As such responsibility for treat- ment rests largely with the patient (Keefe & Bradley, 1984). Home practice is often encouraged with these techniques, as is application to stressful sit- uations and events. One interesting finding that has emerged with respect to headache is that home practice appears to be important with relaxation, but not necessarily with biofeedback (Blanchard, 1992). In addition to relaxation strategies and biofeedback, imagery and hypno- sis are also used to achieve similar effects with chronic pain patients 10. PSYCHOLOGICAL INTERVENTIONS AND CHRONIC PAIN 277 (Arena & Blanchard, 1996). To the extent that they rely on effective relax- ation, respondent theory is relevant to them. Imagery involves the purpose- ful use of visual images to strengthen distraction and/or to transform as- pects of the pain experience. Hypnosis involves suggestion for decreasing discomfort or transforming or altering pain into less noxious sensations (Syrjala & Abrams, 1996). Evidence A number of reviews of the effects of relaxation therapy and biofeedback have been carried out with headache (e. There is evidence in support of both biofeedback and relaxation therapy. The research, however, is ham- pered by a number of problems, including differences among studies re- lated to procedures, patient groups, and duration of treatment (Turk & Flor, 1984). Relaxation therapy alone has been found to be effective for headache (Blanchard, 1992; Compas et al.
