RESULTS:
The sample consisted of 25 volunteers (60% female), with a mean (SD)
age of 33.1 (13.4) years, body mass of 72.6 (18.3) kg and a height of
1.7 (0.1) m, all of which were right-handed (Table 2). Similar peak
torque values were observed between the two methods, whereby the
non-fixed method had with slightly greater peak torque values in
relation to the fixed method ( Table 3). However, no statistical
difference was found for these differences between the mean torques for
any of the movements evaluated.
The reproducibility of the test and retest for the non-fixed method was
categorized as almost perfect for all ten movements evaluated (Table 4).
The Bland-Altman plot demonstrated a greater degree of agreement between
the test and retest of the non-fixed method than that of the fixed
method (Figure 1). The reliability followed a similar behavior, with
higher inter-examiner ICC values for the non-fixed method when compared
to the fixed method (Table 5). The only exception was the measurement of
elbow extension where the fixed method had a higher score (ICC :0.81;
95% CI [0.17-0.96]) in comparison to the non-fixed method (ICC:
0.91 (95% CI [0.54-0.98]) (Figure 2).
