Statistical methods for the comparison of measurements derived from orthodontic imaging
2000
Biometric comparison procedures for dental imaging methods with continuous outcome were reviewed, mainly concentrating on assessment and comparison of accuracy and precision according to the study design. Univariate graphical and numerical representations of corresponding deviations were summarized to derive a 'check list' of minimum information necessary to compare the measurement methods. The methods reviewed in this investigation are illustrated by the comparison of conventional (radiographic) cephalometry versus assessment using the DigiGraph in 50 female children. A paired t-test and the corresponding confidence interval approach were used to assess deviations in location of two imagin…
Efficacy of 12 weeks of proprioceptive training in patients with multiple sclerosis
2019
This pilot study aims to investigate if specific training protocol can improve the quality of life in people with multiple sclerosis through the improvement of some impaired ability like the balance. We enrolled in our project 20 subjects (age: 34,88 ± 4,45; height: 168,25 ± 8,66 cm; weight: 72,31 ± 17,28 kg) but only 5 completed the study. A proprioceptive training was administered for 12 weeks, 2 times a week, an hour for each session. At the beginning (T0) and at the end of the study (T1), static and dynamic balance parameters were tested. Statistical analyzes were performed using IBM SPSS Statistics 22.Changes in balance and strength between T0, T1 were evaluated using t Student test fo…
