Lumbalni bolni sindrom (LBS) kronični je zdravstveni problem koji ugrožava tjelesnu funkciju, a posebno utječe na hod. U ovom smo radu pokazali na koje prostornovremenske parametre utječu bolovi u križima te kako i hoće li se isti oporaviti nakon primjene minimalno invazivne operacije kralježnice (MISS) i fizioterapije. Analizirali smo prostorno-vremenske parametre hoda grupe od 20 bolesnika s bolovima u križima, tjedan dana prije (grupa 1) i 3-5 tjedana nakon minimalne invazivne operacije kralježnice i fizioterapije (grupa 2). Kontrolnu grupu (grupa 3) činili su 10 zdravih osoba slične dobi i masa. Prosječna brzina hoda bila je značajno niža u grupi 1 nego u grupi 2 (P = 0,04) i u kontrolnoj – grupi 3 (P = 0,03). Duljina koraka bila je značajno manja u grupi 1 nego u kontrolnoj grupi 3 (P = 0,04) i u grupi 2 (P = 0,04). Srednja vrijednost upitnika Roland Morris i indeksa invaliditeta Oswestry bila je statistički značajno veća u grupi 1 nego u grupi 2, (P = 0,003), odnosno (P = 0,002). Studija je pokazala
značajno nižu vertikalnu reakcijsku silu tla u grupi 1 nego u kontrolnoj grupi 3 (P = 0,02). Svi prostorno-vremenski parametri i sila reakcije podloge pokazali su razlike između grupa, ali je najznačajnija razlika utvrđena u brzini hodanja, duljini koraka i vertikalnoj sili reakcije podloge (GRF). Takav rezultat ukazuje na značajno smanjenje invalidnosti i bolova nakon operacije i fizioterapije.The lower back pain syndrome (LBP) is a chronic health problem that compromises physical function, and especially affects the walk. In this paper we have shown which spatio-temporal parameters are affected by low back pain and how and whether the same recover after minimal invasive surgery (MISS) and physiotherapy. We have analysed the group of 20 patients with low back pain,
with kinetics and kinematics measures, one week before (group 1) and 3-5 weeks after minimal invasive surgery and physiotherapy (group 2). For control group (group 3) we provided the same measurements in 10 healthy people of the similar age and weight. The average walking speed was significantly lower in the group 1 than in the group 2 (P=0.04), and in control group (P=0.03). The step length was significantly less in the group 1 than in control group (P=0.04) and in the group 2 (P=0.04). The mean value of Roland Morris Questionnaire and Oswestry Disability Index was statistically significantly higher in the group 1 than in the group 2, (P=0.003) and (P=0.002), respectively. The study has showed significantly lower vertical ground reaction force in the group 1 than in control group (P=0.02). All of the spatio-temporal parameters and ground reaction force have shoved difference between groups, but the most significant difference has been found for the walking speed, step length and vertical ground reaction force (GRF). Such result indicates significant decrease of disability and pain after surgery and physiotherap
