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 evaluate the validity of physical examinations by assessment of correlation between physical examinations and CT measurements in children with intoeing gait and the causes of intoeing gait by age using CT measurements.MethodTwenty-six children with intoeing gait participated in this study. The internal and external hip rotation, thigh-foot angle and transmalleolar angle were measured. In addition, femoral anteversion and tibial torsion of the subjects were assessed using a CT scan. The measurements of torsional angles were performed twice by two raters. The correlation coefficients between physical examinations and CT measurements were calculated using Pearson correlation. The data was analyzed statistically using SPSS v12.0.ResultsThe correlation coefficients between physical examinations and CT measurements were not high. Before 5 years of age, intoeing gait was caused by femoral anteversion in 17.86%, tibial torsion in 32.29% and the combination of causes in 35.71% of cases. After 6 years of age, the contributions changed to 29.17%, 8.33% and 45.83%, respectively.ConclusionBefore 5 years of age, the common cause of an intoeing gait was tibial torsion, whereas after 6 years of age it was femoral anteversion. Regardless of age, the most common cause of intoeing gait was a combination of causes. This study shows poor correlation between physical examinations and CT. Therefore, it is limiting to use physical examination only for evaluating the cause of intoeing gait in clinical practice.
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.
ObjectiveTo analyze the differences in the vertical ground reaction force (GRF) variables of hemiplegic patients compared with a control group, and between the affected and unaffected limbs of hemiplegic patients using foot scans.MethodsPatients (n=20) with hemiplegia and healthy volunteers (n=20) underwent vertical force analysis. We measured the following: the first and second peak forces (F1, F2) and the percent stances at which they occurred (T1, T2); the vertical force impulse (VFI) and stance times. The GRF results were compared between the hemiplegic patients and control individuals, and between the affected and unaffected limbs of hemiplegic patients. Additionally, we analyzed the impulse of the unaffected limb according to the motor assessment scale (MAS), Brunnstrom stage, and a Timed Up and Go Test.ResultsThe F1s and F2s of the affected and unaffected limbs were significantly less than those of the normal control individuals (p<0.05). The T1s of both the affected and unaffected limbs of the patients were greater than control individuals, whilst the T2s were lower (p<0.05). Greater impulses and stance times were recorded on both sides of the patients than in the limbs of the control individuals (p<0.05). The MAS, Brunnstrom stage and Timed Up and Go Test results were significantly correlated with the VFI of the unaffected limbs (p<0.05).ConclusionThe high impulse values of the unaffected limb were associated with complications during gait rehabilitation. Therefore, these results suggest that unaffected limbs should also be taken into consideration in these patients.
