Background:Following the COVID-19 pandemic,majority of paediatric cochlear implantees(CI)lost follow ups for rehabilitation and tele-therapy was initiated.Present study thus compared the outcome measures of paediatric CI users on tele-therapy versus conventional face to face therapy following COVID-19 pandemic.Method:Twenty seven unilateral paediatric cochlear implantees in the age range of 2e11 years were divided into two groups based on the therapy modality,viz,tele-and face-to-face therapy.Based on the hearing age,participants were further divided into three groups,viz,0e2,2e4,and greater than four years.A complete the test battery comprising Integrated Scales of Development,Speech Intelligibility Rating scale,and Revised Categorical Auditory Perception were administered.The speech&language test battery was performed prior to initiating the rehabilitation and post 12 months of rehabilitation.Results:Results of the present study revealed that conventional rehabilitation had better outcomes compared to teletherapy.The rate of progress after one year of rehabilitation with respect to hearing-age showed a significant difference for the hearing-age group of 0e2 years across the domains of audition,speech and language.Conclusion:The present study indicates that conventional method of the speech-language and auditory rehabilitation is far better compared to the tele rehabilitation services especially for those visiting tertiary care hospitals as most of them belong to lower and middle socioeconomic status.From the results,it can be delineated that with lesser hearing experience,paediatric CI users always need to initially enroll for conventional therapy for better speech-language and auditory outcomes. 展开更多

目的观察远程康复治疗运用在单侧膝关节周围骨折(FAK)内固定术后患者中的可行性、有效性和是否可以作为一种康复模式替代门诊康复。方法46例单侧FAK内固定术后患者,按照个人意愿分为对照组、观察组,每组23例。两组患者在围手术期均实施... 目的观察远程康复治疗运用在单侧膝关节周围骨折(FAK)内固定术后患者中的可行性、有效性和是否可以作为一种康复模式替代门诊康复。方法46例单侧FAK内固定术后患者,按照个人意愿分为对照组、观察组,每组23例。两组患者在围手术期均实施常规护理、康复指导及健康宣教。对照组患者到医院门诊与治疗师面对面进行康复治疗,观察组患者出院前与治疗师相互添加微信并建立远程康复组群聊进行远程康复治疗。比较两组患者治疗前后的膝关节功能及日常生活活动能力。结果治疗前,对照组改良Barthel指数(MBI)评分为(62.22±6.90)分,纽约特种外科医院(HSS)评分为(51.55±7.92)分;观察组MBI评分为(62.50±6.17)分,HSS评分为(52.45±8.04)分。治疗后,对照组MBI评分为(91.66±5.42)分,HSS评分为(88.83±6.34)分;观察组MBI评分为(90.75±4.94)分,HSS评分为(88.30±6.05)分。治疗后,两组患者HSS评分与MBI评分均高于本组治疗前,差异具有统计学意义(P<0.05);两组患者治疗后HSS评分与MBI评分组间比较,差异无统计学意义(P>0.05)。结论远程康复应用在单侧FAK内固定术后患者中具有可行性和有效性,且由于远程康复独特的优点,使其可以作为门诊康复治疗的替代方式。 展开更多
