The amount of connective tissue in the joint capsules also increases, which explains the substantial failure of measures aimed at improving joint mobility during growth. Clinical features and diagnosis Children with severe arthrogryposis (with additional CNS abnormalities) are often incapable of survival. On clinical examination the pattern of joint involvement is symmetrical, and the movement of the joints is restricted generally.

These range from detailed coding of facial expressions (Craig safe 60 mg raloxifene, 1998) to quantification of broad band behaviors (McGrath, 1998), such as screaming or flailing. Behavioral measures have typically been developed for a partic- ular developmental period. For example, specific behavioral measures exist for assessment of premature infants (e. Behavioral measures are especially valuable in the case where self-reports of pain are not possible (e. Research has generally indicated that observer ratings underestimate children’s pain in- tensity (Chambers, Reid, Craig, McGrath, & Finley, 1998), although no re- search has documented age-dependent differences in agreement between observer and child reports of pain. Physiological measures are also employed in the assessment of pain in children (Sweet & McGrath, 1998). These include heart rate, respiratory rate, and skin blood flow, among others. Research has generally shown that such physiological responses tend to habituate over time and are not spe- cific to pain, although they can be useful in providing complementary infor- mation regarding a child’s pain experience (Sweet & McGrath, 1998). As indicated earlier, age-related differences in children’s physiological respon- siveness to pain have been reported (Bournaki, 1997). Regardless of the specific type of pain measure of interest, it is of impor- tance to give consideration to the unique developmental features of the measure and its appropriateness for use with children of particular ages. Al- though it is helpful that available measures have been tailored to children of specific ages, this approach may, in part, hinder our ability to conduct com- parisons of children’s pain responses across developmental periods. Treatment Considerations During Various Stages of Childhood Developmental factors must also be taken into account when considering pain management in children. Pain management techniques can be broadly classified into either pharmacological or cognitive/behavioral approaches. Specific guidelines for the management of children’s acute pain have been established by the American Academy of Pediatrics and the American Pain Society and are beyond the scope of this chapter (AAP, 2001).
