What Researchers Did
Researchers investigated the effects of conservative treatment with hyperbaric oxygen (HBO) therapy in 10 patients with cervical spondylotic amyotrophy (CSA) who had not responded well to conventional rehabilitation.
What They Found
All 10 patients showed a "snake-eyes" appearance on MRI, and their mean symptom duration before HBO was 3.1 months. Manual muscle testing scores significantly improved from a mean of 1.9 pretreatment to 4.4 after HBO therapy, with all 10 patients achieving clinically satisfactory outcomes.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in Japan.
Study Limitations
The primary limitation of this study is its small sample size of 10 patients and its design as a case series, which lacks a control group.
