Original abstract
Hyaluronan (HA) has been recently identified as a key component of the densification of thoracolumbar fascia (TLF), a potential contributor to non-specific lower back pain (LBP) currently treated with manual therapy and systemic or local delivery of anti-inflammatory drugs. The aim of this study was to establish a novel animal model suitable for studying ultrasound-guided intrafascial injection prepared from HA with low and high Mw. Effects of these preparations on the profibrotic switch and mechanical properties of TLF were measured by qPCR and rheology, respectively, while their lubricating properties were evaluated by tribology. Rabbit proved to be a suitable model of TLF physiology due to its manageable size enabling both TLF extraction and in situ intrafascial injection. Surprisingly, the tribology showed that low Mw HA was a better lubricant than the high Mw HA. It was also better suited for intrafascial injection due to its lower injection force and ability to freely spread between TLF layers. No profibrotic effects of either HA preparation in the TLF were observed. The intrafascial application of HA with lower MW into the TLF appears to be a promising way how to increase the gliding of the fascial layers and target the myofascial LBP.
Czech abstract
Hyaluronan (HA) byl nedávno identifikován jako klíčová příčina denzifikace torakolumbální fascie (TLF), která může přispívat k nespecifickým bolestem dolní části zad (LBP), jež jsou v současnosti léčeny manuální terapií a systémovým nebo lokálním podáváním protizánětlivých léků. Cílem této studie bylo vytvořit nový zvířecí model vhodný pro studium ultrazvukem řízené intrafasciální injekce připravené z HA s nízkou a vysokou molekulovou hmotností. Účinky těchto přípravků na mechanické vlastnosti TLF byly měřeny pomocí qPCR, resp. reologie, zatímco jejich mazací vlastnosti byly hodnoceny pomocí tribologie. Králík se ukázal být vhodným modelem fyziologie TLF díky své velikosti umožňující jak extrakci TLF, tak intrafasciální injekci in situ. Tribologie překvapivě ukázala, že HA s nízkou molekulovou hmotností je lepším mazivem než HA s vysokou. Byla také vhodnější pro intrafasciální injekci díky nižší injekční síle a schopnosti volně se šířit mezi vrstvami TLF. Nebyly pozorovány žádné profibrotické účinky žádného z HA preparátů v TLF. Intrafasciální aplikace HA s nižší molekulovou hmotností do TLF se zdá být slibným způsobem, jak zvýšit klouzavost fasciálních vrstev a zaměřit se na myofasciální LBP.
