Table 2. Relationship Between Measured Train-of-Four Ratio Threshold (0.7 or 0.9) and Clinical Weakness
Clinical weakness was detected by visual and tactile assessment of TOF and DBS fade, head lift and tongue depressor tests. Clinical assessment of TOF and DBS fade was performed in all patients (n = 526). Head lift and tongue depressor tests were correctly evaluated in only 331 and 308 patients respectively. Data are presented as actual number and percentage (in parentheses). By example, among the 85 patients having a TOF ratio less than 0.7, a tactile TOF fade was detected in 23 (27%) of them and was absent in 62 (73%).
DBS = double-burst stimulation; TOF = train-of-four.
