Original abstract
The objective of this study is to develop a reliable tribological model to enable a more thorough investigation of the frictional behavior of fascia tissues connected to non-specific lower back pain. Several models were designed and evaluated based on their coefficient of friction, using a low-frequency, low-load reciprocating motion. The study found that two technical elastomers, layered on PDMS to simulate the fascia and underlying muscle, are suitable substitutes for biological tissue in the model. The influence of tribopair geometry was also examined, and the results showed that greater conformity of contact leads to a lower COF, regardless of the material combination used. Finally, the friction properties of HA of various molecular weights and concentrations were tested.

Cílem této studie je vyvinout spolehlivý tribologický model, který by umožnil důkladnější zkoumání třecího chování fasciálních tkání spojených s nespecifickou bolestí dolní části zad. Bylo navrženo a vyhodnoceno několik modelů na základě jejich koeficientu tření s využitím nízkofrekvenčního vratného pohybu s nízkým zatížením. Studie zjistila, že dva technické elastomery navrstvené na PDMS, které simulují fascii a pod ní ležící sval, jsou vhodnými náhradami biologické tkáně v modelu. Byl také zkoumán vliv geometrie tribopáru a výsledky ukázaly, že větší shodnost kontaktu vede k nižšímu COF bez ohledu na použitou kombinaci materiálů. Nakonec byly testovány třecí vlastnosti HA o různých molekulových hmotnostech a koncentracích.
