Abstract:
The effectiveness of hyperbaric oxygen therapy (HBO) in predicting the recovery after surgery in patients with cervical compression myelopathy was evaluated. HBO has been used to treat brain and spinal cord diseases, but the effect is generally temporary. This is the first paper to utilize HBO as a diagnostic tool to evaluate the functional integrity of the spinal cord. The study group consisted of 41 cervical myelopathy patients aged 32-78 years. Before surgery, the effect of HBO was evaluated and was categorized as four grades. The severity of the myelopathy and the recovery after surgery were evaluated by the score proposed by the Japanese Orthopaedic Association (JOA score). The correlation between many clinical parameters including the HBO effect and the recovery rate of JOA score was evaluated. The recovery rate of JOA score was found to be 75.2 +/- 20.8% in the excellent group, 78.1 +/- 17.0% in the good group, 66.7 +/- 21.9% in the fair group and 31.7 +/- 16.4% in the poor group. There was a statistically significant correlation between the HBO effect and the recovery rate of the JOA score after surgery (r = 0.641, P < 0.0001). The effect of HBO showed a high correlation with the recovery rate after surgery as compared to the other investigated parameters. HBO can be employed to assess the chance of recovery of spinal cord function after surgical decompression. Ishihara, Matsui, Kitagawa, Yonezawa, Tsuji, , , , (1997).
