Ключевые выводы
- Pain at day 28: 61.2 to 33.1 mm with leeches vs 61.6 to 59.8 mm with exercise (difference -25.2 mm, p=0.0018)
- Physical impairment, function and physical quality of life also improved significantly at days 28 and 56
- Patients expected more from leech therapy, but expectations did not significantly affect the findings
Ограничения

- Small number of patients (25 and 19 analysed)
Клиническое значение
A single leech session lowered chronic low back pain in the short term and improved function and quality of life over 8 weeks, compared with exercise therapy. The authors name the lack of blinding and the small sample as the main limitations.
