The use of cranial electrotherapy stimulation in the treatment of closed-head-injured patients.
This double-blind study sought to discover if cranial electrotherapy stimulation (CES), which is a known treatment of depression, anxiety and insomnia in non-head-injured patients, could be an effective, drug-free treatment of stress-related symptoms in the closed-head-injured (CHI) patient. In this study 10 CHI patients treated for 45 min daily, 4 days a week for 3 weeks, responded significantly on all negative mood factors of the Profile Of Mood States, while five sham-treated and six placebo controls did not. While the majority of the patients were known seizure cases, no patient suffered a seizure during CES therapy. No placebo effects were found, nor were any negative effects from CES treatment seen.
No evidence was provided to support the use of CES treatment for inertia, a component of apathy. Between-group statistical analyses were not conducted and it was therefore not possible to determine the efficacy of the treatment relative to no treatment or sham treatment. Results regarding the effectiveness of treatment can only be inferred, and this evidence is based on only one trial with a small sample size. More randomised controlled trials evaluating different ways of treating apathy would be valuable. Trials should have larger sample sizes and use rigorous research designs and statistical analyses appropriate for examining between-group differences.
