ABSTRACT
Objective Discuss the effect of the Rhythmic auditory stimulation with treadmill training on freezing of gait in patients with parkinson's disease.Method 68 patients with parkinson's disease randomly divided into 2 groups.The control group uses conventional drug treatment in parkinson's disease patients according to the condition of patients.The comprehensive training group using body weight support treadmill training combined with rhythmic stimulation training for 8 weeks.The two group subjects were proceeded gait tests by freezing of gait questionnaire 、functional independence measure、five time sit to stand test、timed up and go test、berg balance Scale eight weeks after training.Result The comprehensive training group had a significant difference compared with the control group (P ＜ 0.01)in decreased freezing of gait questionnaire score,decreased functional independence measure score,decreased five time sit to stand test times,decreased timed up and go test score,increased berg balance Scale score.Conclusion Rhythmic auditory stimulation with treadmill training can improve freezing of gait function of patients with parkinson's disease.
ABSTRACT
Objective To investigate the imaging features of the nigrosomes-1 region in the substantia nigra at 3.0 T with enhanced gradient echo T2 star weighted angiography(ESWAN), and to explore its clinical value in the evaluation of Parkinson disease (PD). Methods Fifty-four patients diagnosed with PD (PD group), and 51 non-PD volunteers (N-PD group) were scanned with 3.0 T ESWAN, who had selected randomly. The widths of the typical high signal correspondence with the nigrosomes-1 region (a), the width at the middle of the substantia nigra (b) and the width of the banded high signal of which the oval structure were not displayed (c) were measured and collected. The result of reclassification performed by 2 physicians were compared with clinical gold standard. Specificity and sensitivity were calculated; Eleven outpatients with clinically suspected PD but undiagnosed (UD group) were continusouly selected. They received the same scanning and were performed with imaging diagnosis according to the conclusions of previous studies, then compared the imaging diagnosis with the final clinical diagnosis. Results In non PD group, hyperintensity of nigrosomes-1 were shown in 49 cases (96.1%) in bilateral or unilateral of the SN, the hyperintensity were shaped as“drop”, wedge or oval and the average size (a/b) was (0.31 ± 0.07)mm approximately; PD group, all 54 cases (100.0%) of the oval rear the“drop”were completely disappeared. The sensitivity of the loss of the hyperintensity of nigrosomes-1 for the diagnosis of PD was about 100.0%(54/54)and the specificity of it was about 96.08%(49/51). In UD group, 7 cases with the“drop”completely missed and 1 case with smaller“c”were clinically proven to PD, 2 cases with the typical hyperintensity and 2 case with larger“c”were proven to Parkinson plus syndrome. Conclusions The nigrosomes-1 typical hyperintensity in PD patients' substantia nigra on the 3.0 T ESWAN are disappeared. There may be an effective method for PD and Parkinson's plus syndrome identification that by analyzing of the presence or absence of the typical hyperintensity and its size in the patients with symptoms of PD.
