Uvod: Indeks dinamične hoje (DGI) je zanesljivo in veljavno orodje za oceno sposobnosti hoje pri spreminjajočih se zahtevah okolja in tveganja za padce na populacijah starejših odraslih in pacientih z okvaro osrednjega živčnega sistema. Zaradi restriktivnega načina ocenjevanja so avtorji oblikovali modificirano različico (mDGI). Čeprav so za paciente z okvaro perifernega živčevja na spodnjem udu (OPŽSU) značilni atrofija, spremenjeno občutenje, slabše ravnotežje in spremenjen vzorec hoje, ne poznamo standardiziranega testa za oceno tveganja za padce pri različnih zahtevah med hojo. Validacija mDGI bi omogočila pridobitev primernega merilnega orodja. Namen: Prevesti izvirnik mDGI v slovenski jezik, pri pacientih z OPŽSU preveriti zanesljivost posameznega preiskovalca in med preiskovalci ter sočasno veljavnost s testom hoje na 10 metrov (10MWT), časovno merjenim testom vstani in pojdi (TUG) ter zgodovino padcev. Metode dela: V raziskavi je sodelovalo 20 preiskovancev, starih od 21 do 64 let. Postopek prevajanja mDGI smo izvedli po zlatem standardu prevajanja naprej in nazaj. Pet preiskovalcev je izvedlo ocenjevanje za določitev zanesljivosti. Ugotavljali smo povezanost rezultatov mDGI z izidi testov 10MWT in TUG ter s podatki o padcih. Za oceno zanesljivosti smo uporabili intraklasni korelacijski koeficient (ICC), za oceno povezanosti pa Pearsonov korelacijski koeficient (r). Rezultati: Končna ocena mDGI je pokazala odlično zanesljivost posameznega preiskovalca (ICC = 0,86–0,98) in med preiskovalci (ICC = 0,95–0,99). Zanesljivost posamezne naloge mDGI je bila visoka do odlična pri posameznem preiskovalcu (ICC = 0,76–0,98) in med preiskovalci (ICC = 0,85–0,98). Zanesljivost posamezne postavke naloge je variirala od nizke do odlične. mDGI je bil visoko do odlično povezan z 10MWT (r = –0,85) in odlično povezan s TUG (r = –0,91). Ugotovljena nizka povezanost mDGI s padci (r = –0,22) in napovedna verjetnost padcev sta bili statistično neznačilni (p > 0,05). Razprava in zaključek: Slovenski prevod mDGI je zanesljiv in veljaven na populaciji pacientov z OPŽSU. Potrdili smo dosedanje ugotovitve o zanesljivosti in sočasni veljavnosti testa mDGI, povezanosti s padci zaradi majhnega vzorca nismo mogli dokazati. Predlagamo nadaljnje visokokakovostne raziskave na večjem vzorcu in v primerjavi z drugimi merilnimi orodji.

• Title: Reliability and validity of the Slovenian translation of the modified Dynamic Gait Index in patients with peripheral nerve damage of the lower limb : master thesis

Abstract

Introduction: The Dynamic Gait Index presents a reliable and valid outcome measure for walking ability under changing environmental demands and fall risk in older adults and patients with central nervous system impairments. Due to its restrictive scoring method, the authors developed the modified version (mDGI). Even though patients with peripheral nerve damage of the lower limb (PNDLL) typically present with muscle atrophy, altered sensation, impaired balance, and abnormal gait patterns, there is currently no standardized test available to assess fall risk under varying gait demands. The validation of the mDGI would provide an appropriate measurement tool. Purpose: Translation of the original version of the mDGI into Slovene language, evaluation of its intra-rater and inter-rater reliability, assessment of its concurrent validity with the 10-Meter Walk Test (10MWT), the Timed Up and Go (TUG) test and fall history in patients with PNDLL. Methods: The study included 20 participants aged between 21 and 64 years. The translation process followed the gold-standard forward–backward method. Five raters were a part of the reliability assessment. We examined the correlations between mDGI and outcomes of the 10MWT, TUG and reported fall history. Intraclass correlation coefficients (ICC) were used to assess reliability, Pearson’s correlation coefficients (r) to assess validity. Results: Excellent intra-rater (ICC = 0,86–0,98) and inter-rater reliability (ICC = 0,95–0,99) were found for the total mDGI score. Task-level reliability of individual mDGI items was high to excellent for both intra-rater (ICC = 0,76–0,98) and inter-rater assessment (ICC = 0,85–0,98). Reliability for individual scoring components varied from low to excellent. The mDGI demonstrated a strong to excellent correlation with the 10MWT (r = –0,85) and an excellent correlation with the TUG (r = –0,91). Neither the weak negative correlation with fall history (r = –0,22) or the predictive value for future falls was statistically significant (p > 0,05). Discussion and conclusion: The Slovenian translation of the mDGI is a reliable and valid measurement tool in population of patients with PNDLL. Our findings confirm previous evidence regarding the reliability and concurrent validity of the mDGI. However, due to the small sample size, we were unable to establish a statistically significant association between the mDGI and fall history. Further high-quality studies with larger sample sizes and comparisons with other measurement tools are needed to support the clinical use of the mDGI for fall risk assessment.
