新版明目功运动处方对大学生视疲劳的干预疗效研究OA

Background In the current digital era,the unprecedented abundance of mobile video content has led to a high prevalence of visual fatigue among individuals who engage in prolonged screen exposure.This issue is particularly prominent among adolescents and university students,who often face heavy academic demands.Existing studies have confirmed that the prevalence of visual fatigue among Chinese university students is 53.3%,and this figure continues to rise.Therefore,there is a need to explore proactive health management approaches to promote recovery and implement preventive strategies.Objective This study investigates the rehabilitative effects of a new eyesight improving Qigong exercise prescription on visual fatigue symptoms among university students with prolonged screen exposure.It aims to provide empirical evidence supporting the use of traditional Chinese exercise therapy as an innovative approach for alleviating visual fatigue in this population.Methods From September 2021 to January 2024,a total of 101 university students with visual fatigue were recruited from 3 universities(including 30 students majoring in Optometry from Nanjing University of Chinese Medicine,18 students majoring in Sports Medicine from Beijing Sport University,and 53 students from majors including Rehabilitation Therapy from Nanjing Sport Institute).Participants were randomly divided into an experimental group(new edition eyesight improving Qigong exercise prescription)and a control group(outdoor walking).After 30 days,the following parameters were assessed in both groups:refractive diopters of the left and right eyes,uncorrected visual acuity of the left and right eyes,attention level,total score on the Convergence Insufficiency Symptom Survey(CISS)scale,average heart rate,total sleep duration,rapid eye movement(REM)sleep duration,light sleep duration,and deep sleep duration.Results After treatment,compared with before treatment,the uncorrected visual acuity of both eyes in the experimental group showed statistically significant differences(P<0.05),and the refractive diopter of the right eye in the experimental group showed a statistically significant difference compared with before treatment(P<0.05).After treatment,the time spent on attention reading tests(6×6 and 7×7 grids)in the experimental group was lower than in the control group(P<0.05);the time spent on the 7×7 grid attention reading test in the experimental group after treatment was lower than before treatment(P<0.05).After treatment,the total CISS scale score in the experimental group was lower than in the control group(P<0.05),and the total CISS scale score in the experimental group after treatment was lower than before treatment(P<0.05).After treatment,the total sleep duration and deep sleep duration in the experimental group were higher than in the control group(P<0.05);the total sleep duration and deep sleep duration in the experimental group after treatment were higher than before treatment(P<0.05).After treatment,all five items of visual dysfunction symptom scores in the experimental group were lower than in the control group(P<0.05).After treatment,all three items of periocular discomfort symptom scores in the experimental group were lower than in the control group(P<0.05).After treatment,both items of psychological and physical discomfort symptom scores in the experimental group were lower than in the control group(P<0.05).Conclusion The new version of eyesight improving Qigong exercise prescription effectively alleviates visual fatigue symptoms across three dimensions,visual disturbances,periocular discomfort,and physical and mental discomfort,while significantly improving sleep quality and duration,as well as enhancing attention levels.It also leads to mild improvements in uncorrected visual acuity in both eyes,thereby promoting recovery from visual fatigue in a safe and effective manner.
