If the muscle contractures are severe enough to make the placement of the foot in a sufficiently correct position impossible, cast correction can rem- edy the situation and facilitate the orthotic management (⊡ Fig. Serious cases of clubfoot are problematic however, since they can lead to excessive stresses on the lateral edge of the foot with the risk of pressure ulcers. The efficiency of stretching exercises can be enhanced by the injection of botulinum toxin into the contracted muscles.

Unilateral disturbances in sudomotor function determined by quantitative sudo- motor axon reflex test (QSART) and thermoregulatory sweat test (TST) also have been reported in patients with chronic CRPS lamictal 50 mg otc symptoms 10 weeks pregnant. Sensory Dysfunction Sensory disturbances are common in patients with CRPS types I and II and predominantly consist of hyperalgesia purchase lamictal 200mg treatment viral pneumonia, allodynia, and spontaneous pain. Quantitative sensory testing (QST) demonstrates an increase in warm percep- tion thresholds and a decrease of cold pain thresholds in patients with CRPS types I and II. Sensory impairments frequently extend beyond the affected area and may involve quadratic or hemilateral regions of the body. Motor Dysfunction Motor disturbances are prevalent in patients with CRPS types I and II and are independent of sensory and autonomic complaints. The most frequently described motor disturbance is loss of function of the affected extremity. Detailed neurological examination may detect objective evidence of isolated motor weakness, muscle atrophy, tremor, dystonia, or ataxia. Furthermore, electrodiagnostic tests such as electromyography and nerve con- duction velocity can be used to document muscle and large fiber abnormalities, respectively. Similarly, muscle power can be assessed by measuring grip force strength or by manual muscle testing. A recent study has demonstrated neurophysiological evi- dence of impairment of central sensorimotor integration in patients with CRPS type I. These motor deficits may be secondary to abnormal integration of visual and sensory inputs to the parietal cortex. CNS Dysfunction Evidence suggests that certain autonomic, motor, and sensory disturbances in patients with CRPS are caused by dysfunction within the CNS whereas cer- tain aspects of the pain itself may be related to aberrant peripheral mechanisms. Potential peripheral and central mechanisms are described elsewhere [7, 44]. Occasionally, dysfunction of the sensory, motor, or autonomic nervous system may involve bilateral structures after unilateral nerve or tissue injury. In addition, several investigators have described CNS abnormalities by fMRI, Grabow/Christo/Raja 98 MRS, or SPECT. Recent investigation suggests that patients with CRPS may develop functional or structural cortical reorganization and change in central representation of sensory maps. However, it is unclear whether these abnor- malities are a result of the chronic pain or whether they represent specific regions of primary dysfunction within the CNS. Treatment Algorithm for CRPS The therapeutic strategy for patients with CRPS involves the concurrent utilization of pharmaco-, physio-, and psychotherapy. However, randomized controlled trials (RCTs) investigating the impact of psychological interventions on homogenous groups of patients with neuropathic pain, including patients with CRPS, have not been undertaken. Nevertheless, principles derived from operant and cognitive behavior theory are useful to treat chronic pain patients in general and these strategies should be used for patients with CRPS. The goal of pharmacological therapy is to reduce pain in order to facilitate functional restoration. In general, medications that are effective for the treat- ment of neuropathic pain are used for patients with CRPS. In general, desensitization and physical rehabilitation cannot proceed without adequate pain control. Most authorities believe that active participation in physical therapy is instrumental for improve- ment in patients with CRPS. To date, only the short-term efficacy of physical therapy has been demonstrated by an RCT specifically for patients with CRPS. Recent RCTs have demonstrated the efficacy of spinal cord stimulation for the treatment of pain and intrathecal baclofen for the treatment of dystonia in patients with CRPS. The use of these interventional techniques should be considered in the treatment algorithm when other therapies have failed. A sum- mary of current therapeutic strategies for CRPS has been published.
