Objective
To investigate the relationship between maximal tongue protrusion length (MTPL) and dysphagia in post-stroke patients.
Methods
Free tongue length (FTL) was measured using the quick tongue-tie assessment tool and MTPL was measured using a transparent plastic ruler in 47 post-stroke patients. The MTPL-to-FTL (RMF) ratio was calculated. Swallowing function in all patients was evaluated via videofluoroscopic swallowing study (VFSS), PenetrationAspiration Scale (PAS), Functional Oral Intake Scale (FOIS), and Videofluoroscopic Dysphagia Scale (VDS).
Results
The MTPL and RMF values were significantly higher in the non-aspirator group than in the aspirator group (MTPL, p=0.0049; RMF, p<0.001). MTPL and RMF showed significant correlations with PAS, FOIS and VDS scores. The cut-off value in RMF for the prediction of aspiration was 1.56, with a sensitivity of 84% and a specificity of 86%.
Conclusion
There is a relationship between MTPL and dysphagia in post-stroke patients. MTPL and RMF can be useful for detecting aspiration in post-stroke patients.

Objective
To investigate the optimal sonographic method for diagnosing carpal tunnel syndrome (CTS) in patients with diabetic sensorimotor polyneuropathy (DSP).
Methods
A total of 190 participants were divided into four groups based on DSP history and electrodiagnostic results of CTS. The absolute parameters were measured at baseline and the relative values were calculated: maximal cross-sectional area (CSA) of the median nerve throughout the carpal tunnel (Mmax), median nerve CSA at the forearm level (Mf), ulnar nerve CSA at the pisiform level (Upi), difference between Mmax and Mf (∆MM), and difference between Mmax and Upi (∆MU). Then, the optimal ultrasonographic parameters for diagnosing CTS, according to the presence of DSP, using absolute and relative cutoff values were analyzed.
Results
Median and ulnar nerve CSAs were significantly larger in the DSP group than in the control group. In the DSP participants, the mean Mmax, ∆MM, and ∆MU values were significantly larger in patients with both DSP and CTS than in patients with DSP only. The Mmax thresholds of 9.5 mm2 in the control group and 11.5 mm2 in the DSP group showed the greatest sensitivity and specificity for diagnosing CTS. The ∆MM thresholds of 2.5 mm2 and ∆MU thresholds of 4.5 mm2 had the greatest sensitivity and specificity in both the DSP and control groups.
Conclusion
Measurement of Mmax, ∆MM and ∆MU is an optimal ultrasonographic evaluation method for diagnosing CTS in patients with DSP.
