Uvod: Terapija udarnim valom (TUV) (od engl. shockwave therapy) je neinvazivna metoda temeljena na mehaničkim pulsovima koji se u obliku vala šire kroz ljudsko tijelo te izazivaju mikroskopske intersticijalne i ekstracelularne biološke učinke među kojima je i regeneracija tkiva. Cilj: Cilj ovog retrospektivnog istraživanja bio je ispitati učinkovitost i razlike u liječenju bola TUV-om u pacijenata s dijagnozama plantarni fascitis, kalcificirajući tendinitis ramena i lateralni epikondilitis lakta nakon upotrebe tri i pet uzastopnih tretmana. Ispitanici i metode: U radu su korišteni podatci pacijenata iz baze podataka Zavoda za fizikalnu i rehabilitacijsku medicinu Kliničkog bolničkog centra u Rijeci, a pri tome su u skladu s Helsinškom deklaracijom ostali anonimni: dob, spol, mjerenja intenziteta bola dobivena uz pomoć vizualno analogne skale (od engl. Visual Analogue Scale, VAS). Ispitanici su podijeljeni u dvije grupe za svaku dijagnozu (TUV3 i TUV5). Ispitivanje je sadržavalo ukupno 148 pacijenata: plantarni fascitis N = 50, kalcificirajući tendinitis ramena N = 50 i lateralni epikondilitis lakta N = 48. Rezultati: Primjena terapije udarnim valom kod pacijenata s dijagnozama plantarni fascitis, kalcificirajući tendinitis ramena i lateralni epikondilits lakta, s ciljem smanjenja intenziteta bola, pokazala se uspješnom. Dobivenim rezultatima utvrđeno je da primjena pet TUV tretmana dovodi do boljih rezultata smanjenja bola u sve tri dijagnoze negoli samo tri primijenjena tretmana (p <0,001; p <0,001; p <0,001). Nadalje je utvrđeno da se nakon tri primijenjena tretmana postigao bolji učinak smanjenja bola kod plantarnog fascitisa negoli kod kalcificirajućeg tendinitisa ramena i lateralnog epikondilitisa lakta, dok nakon pet primijenjena tretmana nije bilo razlike u smanjenju bola među dijagnozama. Zaključak: Ova studija preporučuje primjenu pet tretmana kod sve tri dijagnoze kako bi pacijenti imali bolji učinak smanjenja bola.; Introduction: Shock wave therapy (SWT) is a non-invasive method based on mechanical pulses widening through the human body and causing microscopic interstitial and extracellular biological effects, including tissue regeneration. Aim: The aim of this retrospective study was to analyze efficacy and differences in pain treatment with SWT in patients with plantar fasciitis, calcific tendinitis of the shoulder and lateral epicondylitis of the elbow after three and five consecutive treatments. Participants and methods: The patients data were taken from the database at the Departmentof Physical and Rehabilitation Medicine of the Clinical Hospital Center in Rijeka and used only in purpose of this work, and according to the Helsinki Declaration, stayed anonymous: age, sex, pain intensity measurements obtained using the Visual Analogue Scale. The participants were devided into two groups (TUV3 and TUV5). The data were taken from 148 patients: plantar fasciitis N = 50, calcific tendinitis of the shoulder N = 50 and lateral epicondylitis of the elbow N = 48. Results: The therapy with SWT proved to be successful in patients with diagnosis of plantar fasciitis, calcific tendinitis of the shoulder and lateral epicondylitis of the elbow. The analyzed results showed that three or five treatments both resulted in pain reduction in all three diagnosis, with five treatments being more efficient than just three applied treatments (p <0,001; p <0,001; p <0,001). It has also been established that after three applied treatments a better effect of pain reduction is achieved in plantar fascitis than in calcific tendinitis of the shoulder and lateral epicondylitis of the elbow, and after five applied treatments there was no difference in pain reduction between diagnoses. Conclusion: Therefore, this study recommends the application of five treatments in all three diagnoses in order for patients to have better pain relief.
