Background:
Acute burn patients suffer pain and secondary hyperalgesia. This alters movement patterns and impairs function. Non-pharmacological methods of treatment are limited and lack rigorous testing and evidence for use. The treatment in this case series was designed to direct conscious attention to, and normalise sensation of, the injured limb in pain free way. The aim of the study was to describe a cortical training programme (CTP) in acute upper limb burn patients and to investigate the efficacy, safety and feasibility of the protocol.
Method:
The study is a descriptive case series (n=6). Study tasks engaged sensory and motor nerves to influence the perception of the injured area. Visual and tactile inputs to maintain and, or normalise the homuncular map were central to the intervention.
Results:
One patient, who commenced the study without resting pain, responded negatively. The remaining five patients had reduced pain and fear avoidance behaviours with associated improvement in arm function.
Conclusions:
The CTP approach is safe and feasible for use with acute burn patients where pain is reported at rest. Comparative studies are required to determine the relative efficacy of the program to usual interventions and the patients who may benefit from the technique.
