| Abstrakt: | Unlabelled: Goniometric measurement is a standard method used to quantify limited ankle dorsiflexion (DF). However, compensatory motion at the subtalar and midtarsal joints might also contribute to the amount of ankle DF obtained by goniometric measurements. The purpose of this study was to examine the effect of goniometric alignment on DF range of motion measurement among patients following ankle arthrodesis or arthroplasty and age- and gender-matched controls. A total of 22 participants were recruited to participate in this observational cohort study, including 7 patients following total ankle arthroplasty (2 male, 5 female; mean age = 67.5 years, standard deviation [SD] = 9.6 years), 4 patients following ankle arthrodesis (2 male, 2 female; mean age = 70.5 years, SD = 5.2 years), and 11 age- and gender-matched controls (4 male, 7 female; mean age 67.5 years, SD = 9.0 years). Two investigators measured and recorded ankle DF passive range of motion (PROM) using a randomly determined sequence of 2 alignment methods: (1) the distal aspect of the lateral calcaneus, and (2) the fifth metatarsal. One-sample t tests were performed to assess differences in ankle DF between the 2 different alignment methods. Significantly greater degrees of DF were obtained when aligning with the fifth metatarsal versus the lateral calcaneus on the patients' uninvolved sides and the randomly selected side of matched controls (P < .05) but not on the patients' operative side (P > .05). This study found that more degrees of DF PROM are measured when aligning a goniometer with the fifth metatarsal versus the calcaneus on the uninvolved side of patients and matched controls. Levels of Evidence: Diagnostic, Level IV. |
