To evaluate the effects of respiratory muscle training (RMT) on pulmonary function, respiratory complications, and stroke-related disabilities in patients with acute stroke. Methods: One hundred twenty-two subjects with stroke admitted to the stroke rehabilitation center of Inje Hospital between August 2016 and May 2018 were recruited. After the initial exclusion, the remaining patients were assigned to the RMT group (36 patients) or the standard rehabilitation (SR) group (28 patients who did not undergo RMT). A total of 44 patients completed the study, with 22 patients in each group. The RMT program consisted of air-stacking exercise, manually assisted coughing, inspiratory and expiratory muscle strengthening, cough exercises, and respiratory reeducation. Pulmonary function and respiratory muscle strength were evaluated before commencement and after 1 mo of RMT. The Functional Ambulation Category score, Korean version of the Modified Barthel Index, Shoulder Abduction and Finger Extension score, and handgrip power were assessed. The incidence of pneumonia was also evaluated. Results: Both pulmonary function and respiratory muscle strength significantly improved in both groups. However, differences (%) in the RMT group was greater for all parameters of pulmonary function and respiratory muscle strength. Respiratory complications at 1 yr were significantly lower in the RMT group (P = .016). Conclusion: Four weeks of comprehensive RMT in patients with acute stroke resulted in significantly greater improvements in both pulmonary function and respiratory muscle strength than SR. Therefore, RMT has the potential to reduce post-stroke respiratory complications.

ObjectiveTo investigate swallowing characteristics of patients with dysphagia caused by anterior cervical osteophytes (ACOs) and compare clinical courses according to treatment options.MethodsA retrospective analysis of 1,866 videofluoroscopic swallowing studies (VFSS) of patients with ACOs from electronic medical records was performed. Patients with other diseases that could explain the dysphagia were excluded. Dysphagia characteristics and severity and clinical and radiological characteristics of subjects with ACOs were evaluated. Dysphagia characteristics and clinical course were compared among three treatment groups: surgical treatment, swallowing rehabilitation, and conservative treatment.ResultsSubjects were 22 men and 1 woman with a mean age of 78.69±8.01 years. The mean osteophyte thickness was 9.07±3.84 mm. It was significantly thicker in the surgical group than that in other groups (p=0.01). ACOs were most frequently found at C5 level. This level also had the thickest osteophytes. However, videofluoroscopic dysphagia scales (VDS) were not significantly different among the three treatment groups. The pharyngeal phase score of the VDS was significantly higher in the surgical group (p=0.041). Dysphagia severity was decreased significantly in the surgical group at 3 months after the initial VFSS (p=0.004).ConclusionThe main swallowing characteristics in patients with ACOs were dysphagia features of the pharyngeal phase, including inappropriate airway protection, decreased laryngeal elevation, and reduced epiglottis inversion. When determining treatment options, it may be helpful to consider dysphagia severity at pharyngeal phase and osteophyte thickness.

ObjectiveTo determine the efficacy of aquatic treadmill training (ATT) as a new modality for stroke rehabilitation, by assessing changes in gait symmetry, balance function, and subjective balance confidence for the paretic and non-paretic leg in stroke patients.MethodsTwenty-one subacute stroke patients participated in 15 intervention sessions of aquatic treadmill training. The Comfortable 10-Meter Walk Test (CWT), spatiotemporal gait parameters, Berg Balance Scale (BBS), and Activities-specific Balance Confidence scale (ABC) were assessed pre- and post-interventions.ResultsFrom pre- to post-intervention, statistically significant improvements were observed in the CWT (0.471±0.21 to 0.558±0.23, p<0.001), BBS (39.66±8.63 to 43.80±5.21, p<0.001), and ABC (38.39±13.46 to 46.93±12.32, p<0.001). The step-length symmetry (1.017±0.25 to 0.990±0.19, p=0.720) and overall temporal symmetry (1.404±0.36 to 1.314±0.34, p=0.218) showed improvement without statistical significance.ConclusionATT improves the functional aspects of gait, including CWT, BBS and ABC, and spatiotemporal gait symmetry, though without statistical significance. Further studies are required to examine and compare the potential benefits of ATT as a new modality for stroke therapy, with other modalities.

Pincer nail deformity is a severe condition in which the nail bed becomes compressed and the nail shows an overcurvature. We retrospectively analyzed 13 pincer nail deformities treated using our nail plate and bed reconstruction technique. Visual analogue scale scores, the width of nail root, width of nail tip, height of nail tip, width index, and height index were assessed before and after surgery. The overcurvature was corrected after detachment of the nail plate. The nail fold was pushed underneath the nail plate and then fixed. The width of nail tip significantly increased after surgery (p < 0.05) and was maintained during follow-up. The height of nail tip decreased after surgery (p < 0.05). This nail plate and bed reconstruction technique is a simple and quick surgical method for correcting deformities and reduces risks of complications such as skin necrosis and infection compared to other existing surgical techniques. We recommend this efficient surgical technique for the treatment of pincer nails.
