ABSTRACT
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.
ABSTRACT
OBJECTIVE: To demonstrate the efficacy of the balance control trainer (BCT), developed for training patients with balance problems, as a balance assessment tool in subacute stroke patients. METHODS: A prospective cross-sectional study was carried out on 38 subacute stroke patients in their first episode of a stroke, and having the ability to maintain a standing position without aid for at least 5 minutes. Patients were assessed using the BCT (BalPro) 43.7±35.7 days after stroke. The balance was assessed using the Berg Balance Scale (BBS), the Timed Up and Go Test (TUG), a 10-meter walking test (10mWT), a 6-minute walking test (6MWT), and the Korean version of the Modified Barthel Index. The correlation and validity between the BCT and various balance assessments were analyzed. RESULTS: Statistically significant linear correlations were observed between the BCT score and the BBS (r=0.698, p<0.001). A moderate to excellent correlation was seen between the BCT score and 11 of the 14 BBS items. The BCT scores and other secondary outcome parameters (6MWT r=0.392, p=0.048; TUG r=–0.471, p=0.006; 10mWT r=–0.437, p=0.012) had a moderate correlation. CONCLUSION: Balance control training using the BCT (BalPro) showed significant statistical correlation with the BBS, and could therefore be a useful additional balance assessment tool in subacute stroke patients.

OBJECTIVE: To evaluate the effect of hospital-based cardiac rehabilitation (CR) on quality of life (QOL) and physical ability in patients with myocardial infarction (MI). METHODS: Patients with MI who were referred to the Cardiac Health and Rehabilitation Center 2 weeks after percutaneous coronary intervention were divided into CR and non-CR groups. The CR group performed supervised exercises 3 times a week for 2 months. QOL assessment, using the 36-item Short-Form Health Survey (SF-36) and physical ability evaluation were performed at the beginning and end of CR. RESULTS: The CR group demonstrated statistically significant improvements in physical functioning (PF), physical role functioning (RP), bodily pain (BP), general health perceptions (GH), vitality (VT), social role functioning (SF), emotional role functioning (RE), mental health (MH), physical component summary (PCS), and mental component summary (MCS). The non-CR group showed improvement in RP. Secondary outcomes, including resting heart rate (RHR), maximal oxygen consumption (VO(2max)), metabolic equivalent of task (MET), maximal exercise time (ET(max)), stage 3 Borg rating of perceived exertion (3RPE), maximal Borg rating of perceived exertion (RPEmax), and stage 3 rate pressure product (3RPP), improved in the CR group. The non-CR group showed improvements in VO(2max), MET, ET(max), and 3RPE. There were significant differences in improvements in PF, RP, BP, VT, SF, MH, MCS, RHR, VO(2max), MET, ET(max), 3RPE, and 3RPP between the two groups. CONCLUSION: Male patients with MI demonstrated improvements in QOL and physical ability following hospital-based CR; the impact on the mental component was greater than that on the physical component.

OBJECTIVE: To evaluate the safety of nasogastric tube (NGT) removal and change to oral feeding with a food thickener for acute stroke patients in whom a videofluoroscopic swallow study (VFSS) confirmed thin liquid aspiration. METHODS: We retrospectively examined data of 199 patients with first stroke who were diagnosed with dysphagia from 2011 to 2015. Swallowing function was evaluated using VFSS. Patients included in this study were monitored for 4 weeks to identify the occurrence of aspiration pneumonia. The penetration-aspiration scale (PAS) was used to assess VFSS findings. The patients were divided into thin-liquid aspiration group (group 1, n=104) and no thin-liquid aspiration group (group 2, n=95). RESULTS: The feeding method was changed from NGT feeding to oral feeding with food thickener (group 1) and without food thickener (group 2). The PAS scores of thin and thick liquids were 6.46±0.65 and 1.92±0.73, respectively, in group 1 and 2.65±0.74 and 1.53±0.58, respectively, in group 2. Aspiration pneumonia developed in 1.9% of group 1 and 3.2% of group 2 (p=0.578), with no significant difference between the groups. CONCLUSION: We concluded that removing the NGT and changing to oral feeding with a food thickener is a safe food modification for acute stroke patients with thin liquid aspiration. Therefore, we recommend that VFSS should be conducted promptly in acute stroke patients to avoid unnecessary prolonged NGT feeding.

We report a case of a 53-year-old male with traumatic cervical spinal cord injury (SCI). He could not maintain a standing position because of painful spasticity in his lower limbs. A magnetic resonance imaging and electromyography indicated chronic lumbosacral radiculopathy, explaining his chronic low back pain before the injury. For diagnostic as well as therapeutic purposes, transforaminal epidural steroid injection (ESI) to the right L5 root was performed. After the intervention, the spasticity decreased and his ambulatory function improved. This case illustrates that lumbar radiculopathy concomitant with a cervical SCI can produce severe spasticity and it can be dramatically improved by ESI.

OBJECTIVE: To evaluate the accuracy of the swallowing kinematic analysis. METHODS: To evaluate the accuracy at various velocities of movement, we developed an instrumental model of linear and rotational movement, representing the physiologic movement of the hyoid and epiglottis, respectively. A still image of 8 objects was also used for measuring the length of the objects as a basic screening, and 18 movie files of the instrumental model, taken from videofluoroscopy with different velocities. The images and movie files were digitized and analyzed by an experienced examiner, who was blinded to the study. RESULTS: The Pearson correlation coefficients between the measured and instrumental reference values were over 0.99 (p<0.001) for all of the analyses. Bland-Altman plots showed narrow ranges of the 95% confidence interval of agreement between the measured and reference values as follows: 0.14 to 0.94 mm for distances in a still image, -0.14 to 1.09 mm/s for linear velocities, and -1.02 to 3.81 degree/s for angular velocities. CONCLUSION: Our findings demonstrate that the distance and velocity measurements obtained by swallowing kinematic analysis are highly valid in a wide range of movement velocity.

OBJECTIVE: To investigate if adding fiberoptic endoscopic evaluation of swallowing (FEES) to the videofluoroscopic swallowing study (VFSS) will improve the detection of abnormalities related to swallowing and pharyngolaryngeal structures. METHOD: Sixty-nine subjects (47 men, aged 64.8+/-12.0 years) with dysphagia were evaluated using VFSS and FEES simultaneously. VFSS and FEES were independently interpreted by two different examiners, who were blinded to the results of the other study. The foods that were examined were a 5-ml semi-blended diet (SBD), plain yogurt, boiled rice (NRD), and 2-ml (small fluid, SF) and 5-ml (large fluid, LF) diluted liquid barium. The detection rates of penetration or aspiration and of the pharyngeal residues in VFSS and FEES were compared. RESULTS: Combining FEES with VFSS raised the detection rates of penetration (p=0.008 for SF and LF; p<0.001 for SBD, yogurt, and NRD) and of the pharyngeal residues (p<0.001 for SF, SBD, yogurt, and NRD; p=0.001 and 0.002 for LF in the vallecula and pyriform sinus, respectively) in all the food types. Adding FEES also improved the detection of fluid aspiration (p=0.03 and 0.02 for SF and LF, respectively). Oral and pharyngeal lesions such as candidiasis, and other mucosal abnormalities, were also detected by FEES. CONCLUSION: Combining FEES with VFSS raised the diagnostic sensitivities of penetration, aspiration, and pharyngeal residues compared to the evaluation using VFSS alone. It also enabled the visualization of the abnormal structural changes in the pharyngolarynx. FEES can be performed safely by physiatrists.
