人行走时骨盆上下运动参数的模型分析

为了研究正常人行走过程中骨盆在垂直方向的运动特征,提出了一种以测量数据为基础建立骨盆运动参数数学模型的新思想。介绍了基于跑步机的骨盆运动轨迹测量系统,并对30名健康男性青年进行了获取骨盆运动参数的实验研究。实验结果得到了不同受试者分别以不同速度行走时的骨盆在垂直方向的多组运动轨迹,以及运动幅值、周期、初始相位等与行走速度和受试者身高的关系曲线。通过对曲线拟合,建立了各参数及骨盆运动轨迹的数学模型。通过对该模型进一步完善,可使其对康复评定、类人机器人等领域具有一定的应用价值。     

Pain, Anxiety, and Cooperativeness in Children with Cerebral Palsy After Rhizotomy: Changes Throughout Rehabilitation

Assessed pain, anxiety, physical functioning, and cooperativenessin 32 childrenn with spastic cerebral palsy. This is the firststudy to assess children throughout rehabilitation followingselective posterior rhizotomy. Results of the ObservationalScale of Behavioral Distress and observer Likert ratings confirmedthe hypothesis that children's pain and anxiety decrease overtime. Children's physical functioning and cooperativeness improveover time. No significant correlation was found between painand changes in physical functioning. Cognitive impairment, parentalinvolvement, and children's pain behaviors explained 77% and56% of the variance in two forms of cooperativeness. Researchand clinical implications are discussed, and special considerationsregarding pain assessment and management in this populationare addressed     

脑卒中后抑郁及其对神经功能康复的影响

目的:观察脑卒中后抑郁(Post-Stroke Depression,PSD)的发生率和相关因素;探讨选择性5-HT抑制剂对脑卒中后抑郁神经功能康复的影响.方法:选取急性脑脑卒中患者132例(脑梗死78例,脑出血54例),分别在病程2周、1,3,6,12月时给每一位入组患者行PSD诊断、神经功能缺损评分、日常生活能力评分(Activity of Daily Living Scale,ADL)、汉密尔顿抑郁量表(Hamilton Depression Scale,HAMD)评分;同时完成Zung's抑郁自评量表(Self-Rating Depression Scale,SDS)和焦虑自评量表(Self-Rating Anxiety Scale,SAS).结果:①脑卒中患者中约44.70%出现抑郁症状;②脑卒中类型和性别与PSD发生率无相关性(P＞0.05);③PSD的发生率和严重程度与神经功能缺损和日常生活能力下降程度有关.④PSD与病变部位、病灶大小、病灶单侧性均无明显相关(P＞0.05);⑤氟西汀抗抑郁治疗能明显改善病程3、6个月时的神经功能缺损,病程12月时不仅抑郁症状减轻,日常生活能力改善,神经功能缺损减轻尤为显著.结论:脑卒中后抑郁是急性脑血管病患者常见的长期并发症,并可影响患者功能康复的速度和程度.抗抑郁剂治疗能在抑郁症状明显改善的同时,促进患者日常生活能力和神经功能的恢复.     

Eccentric visual acuity in patients with macular disease

A series of cards each containing a two dimensional array of identical Snellen "E's" was used to determine best eccentric visual acuity in patients with macular disease having Snellen visual acuity of 20/70 or worse. Each "full field E" card simultaneously presents the same letter to foveal and parafoveal areas. This test can therefore determine quickly if potentially useful vision is present in any area of the central visual field. In our study of 37 eyes, 70% demonstrated potential visual acuity at least two times better than visual acuity measured by conventional methods, and 20% demonstrated at least a fourfold improvement. This suggests that most patients with macular disease do not spontaneously employ their best remaining area of retina for fixation.     

中药蜡疗结合康复护理对气滞血瘀型腰椎间盘突出症患者腰椎功能的影响

目的 探讨中药蜡疗结合康复护理对气滞血瘀型腰椎间盘突出症患者腰椎功能的影响。方法 选择本院于2019年2月—2020年3月间收治的腰椎间盘突出症患者90例,按随机数字表法分为2组,各45例。对照组行常规康复护理联合单纯蜡泥外敷治疗,在此基础上,研究组行中药蜡疗干预。比较2组疼痛程度、腰椎功能、生活质量。结果 干预后,研究组视觉模拟评分法(VAS)评分(0.45±0.06)较对照组(0.85±0.10)低,腰椎日本骨科协会(JOA)评分(25.26±2.05)较对照组(20.68±3.09)高,差异有统计学意义(t=23.009、8.285,P<0.001);研究组躯体疼痛、生理职能、活力、总体健康、生理功能、社会功能评分(71.30±8.21、75.24±7.98、74.12±8.65、67.59±9.94、79.30±10.01、85.60±6.85)较对照组(62.20±7.28、57.54±6.20、58.89±7.02、49.01±8.04、72.23±8.32、79.15±5.85)高,差异有统计学意义(t=5.563、11.750、9.171、9.749、3.644、4.803,P<0.05)。结论 中药蜡疗结合康复护理可有效减轻气滞血瘀型腰椎间盘突出症患者疼痛程度,改善腰椎功能,提高生活质量。

Machine Learning Algorithms to Predict Mortality and Allocate Palliative Care for Older Patients With Hip Fracture

ObjectivesTo evaluate a machine learning model designed to predict mortality for Medicare beneficiaries aged >65 years treated for hip fracture in Inpatient Rehabilitation Facilities (IRFs).DesignRetrospective design/cohort analysis of Centers for Medicare & Medicaid Services Inpatient Rehabilitation Facility–Patient Assessment Instrument data.Setting and ParticipantsA total of 17,140 persons admitted to Medicare-certified IRFs in 2015 following hospitalization for hip fracture.MeasuresPatient characteristics include sociodemographic (age, gender, race, and social support) and clinical factors (functional status at admission, chronic conditions) and IRF length of stay. Outcomes were 30-day and 1-year all-cause mortality. We trained and evaluated 2 classification models, logistic regression and a multilayer perceptron (MLP), to predict the probability of 30-day and 1-year mortality and evaluated the calibration, discrimination, and precision of the models.ResultsFor 30-day mortality, MLP performed well [acc = 0.74, area under the receiver operating characteristic curve (AUROC) = 0.76, avg prec = 0.10, slope = 1.14] as did logistic regression (acc = 0.78, AUROC = 0.76, avg prec = 0.09, slope = 1.20). For 1-year mortality, the performances were similar for both MLP (acc = 0.68, AUROC = 0.75, avg prec = 0.32, slope = 0.96) and logistic regression (acc = 0.68, AUROC = 0.75, avg prec = 0.32, slope = 0.95).Conclusion and ImplicationsA scoring system based on logistic regression may be more feasible to run in current electronic medical records. But MLP models may reduce cognitive burden and increase ability to calibrate to local data, yielding clinical specificity in mortality prediction so that palliative care resources may be allocated more effectively.
