Effect of Core Stability Training on Trunk Function, Standing Balance, and Mobility in Stroke Patients: A Randomized Controlled Trial.

Background. Trunk function is important for standing balance, mobility, and functional outcome after stroke, but few studies have evaluated the effects of exercises aimed at improving core stability in stroke patients. Objective. To investigate the effectiveness of core stability training on trunk function, standing balance, and mobility in stroke patients. Methods. An assessor-blinded, randomized controlled trial was undertaken in a stroke rehabilitation ward, with 32 participants randomly assigned to an experimental group or a control group (n = 16 each). The experimental group received 400 minutes of core stability training in place of conventional programs within total training time, while the control group received only conventional programs. Primary outcome measures were evaluated using the Trunk Impairment Scale (TIS), which reflects trunk function. Secondary outcome measures were evaluated by pelvic tilt active range of motion in the sagittal plane, the Balance Evaluation Systems Test–brief version (Brief-BESTest), Functional Reach test, Timed Up-and-Go test (TUG), and Functional Ambulation Categories (FAC). A general linear repeated-measures model was used to analyze the results. Results. A treatment effect was found for the experimental group on the dynamic balance subscale and total score of the TIS (P = .002 and P < .001, respectively), pelvic tilt active range of motion (P < .001), Brief-BESTest (P < .001), TUG (P = .008), and FAC (P = .022). Conclusions. Core stability training has beneficial effects on trunk function, standing balance, and mobility in stroke patients. Our findings might provide support for introducing core stability training in stroke rehabilitation.

Asymmetrical skull deformity in children with cerebral palsy: Frequency and correlation with postural abnormalities and deformities

OBJECTIVE Asymmetrical skull deformity is frequently seen in children with cerebral palsy, and may contribute to postural abnormalities and deformities. The aim of this cross-sectional- survey was to determine the frequency of asymmetrical skull deformity and its correlation with clinical parameters. METHODS A 10-item checklist for asymmetrical skull deformity, postural abnormalities, and deformities was developed, and its inter-rater reliability was tested. A total of 110 participants aged 1-18 years (mean age 9.3 years (standard deviation 4.7)) was assessed using the checklist. The frequency of asymmetrical skull deformity was analysed and related to the Gross Motor Function Classification System (GMFCS), postural abnormalities, and deformities. RESULTS The reliability of the checklist was satisfactory (κ > 0.8). Asymmetrical skull deformity was observed in 44 children, 24 showing right and 20 showing left flat occipital deformity. Its frequency was significantly related to GMFCS and with the patterns of asymmetrical posture and deformities (p < 0.05). Children with right flat occipital asymmetrical skull deformity showed predominantly rightward facial direction and right-side-dominant asymmetrical tonic neck reflex, left convex scoliosis, right-side-elevated pelvic obliquity, and left-sided hip dislocation. Those with left flat occipital asymmetrical skull deformity demonstrated the reverse tendency. CONCLUSION Asymmetrical skull deformity is frequent in cerebral palsy and closely related to asymmetrical posture and deformities. This information will be useful to manage these problems.

Stroke Impairment Assessment Set (SIAS). (2). Reliability and Validity of Motor Function Assessment Items of SIAS.

脳卒中の総合的機能障害評価法Stroke Impairment Assessment Setの麻痺側運動機能評価項目群(SIAS-M)の信頼性と妥当性を検討した.脳血管障害20例での検討の結果,一致係数(weighted kappa)はSIAS-M, Brunnstrom stage (BS)およびMotricity Index (MI)いずれも0.80以上であり,3者とも同程度の信頼性を有すると思われた.脳血管障害65例における検討から,SIAS-MとMIおよびSIAS-MとBSとの相関は高く,SIAS-Mの併存的妥当性が示された.しかし散布図から,同一BSにおけるSIAS-Mのばらつきが目立ち,SIAS-Mの方がBSより麻痺の回復をより鋭敏に反映することが推察された.

A comparison of swallowing dysfunction in Becker muscular dystrophy and Duchenne muscular dystrophy

Abstract Purpose: Swallowing dysfunction has been reported in Duchenne muscular dystrophy (DMD), but has not been studied in Becker muscular dystrophy (BMD). The aims of this study were to report the characteristics of swallowing dysfunction in BMD compared with DMD. Materials and methods: The study participants were 18 patients with BMD and 18 patients with DMD. All the patients were examined using videofluorography during swallowing of 5 mL of fluid. The penetration–aspiration scale (P–A scale) and the videofluorographic dysphagia scale (VDS) were used to evaluate dysphagia. Results: Swinyard functional ability stage was not significantly different between the BMD and DMD groups. Rate of aspiration, P–A scale score, and total VDS score did not differ across groups, but the VDS item score for laryngeal elevation was lower in the BMD group than in the DMD group (median scores 4.5 and 9, respectively; p < 0.001). In the BMD group, total VDS score significantly correlated with Swinyard stage (r = 0.78, p < 0.001), but not with age or lung function. Conclusion: Patients with BMD have swallowing problems similar to those observed in patients with DMD when matched according to physical functional status. These patients should be evaluated and followed-up for the duration of their disease. Implications for rehabiliation Dysphagia is one of the most critical problems in patients with progressive neuromuscular disease but dysphagia in patients with Becker muscular dystrophy (BMD) was not well known. Eighteen patients with BMD and 18 patients with Duchenne muscular dystrophy were examined with videofluorography. Patients with BMD have swallowing problems similar to those observed in patients with DMD.

Feasibility of a Respiratory Movement Evaluation Tool to Quantify Thoracoabdominal Movement for Neuromuscular Diseases

BACKGROUND: An objective method to evaluate thoracoabdominal movement is needed in daily clinical practice to detect patients at risk of hypoventilation and to allow for timely interventions in neuromuscular diseases. The clinical feasibility, reliability, and validity of a newly developed method for quantifying respiratory movement using fiber grating sensors, called the Respiratory Movement Evaluation Tool (RMET), was evaluated. METHODS: The time needed to measure respiratory movement and the usability of the measurement were determined by 5 clinicians using the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) 2.0 questionnaire. Thoracoabdominal movement was measured using RMET 3 times in 10 healthy subjects to evaluate intraclass correlation coefficients (ICC). The subjects were encouraged to breathe 10 times while voluntarily changing the amount of air during ventilation simultaneously with the RMET and a spirometer, and their correlations were evaluated to test validity using Pearsons product-moment correlation coefficients. The same measurements were also performed in 10 subjects with Duchenne muscular dystrophy. RESULTS: Real-time recordings of thoracoabdominal movements were obtained over a mean time of 374 ± 23.9 s. With QUEST 2.0, the median score of each item exceeded 3 (more or less satisfied). In healthy subjects, ICC(1,1) ranged from 0.82 to 0.99, and ICC(2,1) ranged from 0.83 to 0.97. Significant correlations were observed between the respiratory amplitudes measured with RMET, and the amount of air during ventilation was measured with a spirometer (r = 0.995, P < .001). In subjects with Duchenne muscular dystrophy, ICC(1,1) ranged from 0.87 to 0.97, and ICC(2,1) ranged from 0.84 to 0.99. The respiratory amplitudes measured with RMET correlated significantly with the amount of air during ventilation with a spirometer (r = 0.957, P < .001). CONCLUSIONS: We developed a novel method of quantifying respiratory movement called RMET that was feasible to use in daily clinical practice.
