Evaluation Of Rehabilitative Effect Of Lower Limb Fracture Based On Motion Capture

With the development and popularization of higher education,college students have become a large social group,and the number of injuries in sports has increased year by year.Among them,the probability of fracture of the lower extremities is becoming higher and higher.The postoperative rehabilitation effect of lower limb fracture directly affects the further treatment plan.Therefore,it is very necessary to study the rehabilitation effect evaluation of lower limb fracture.In this paper,based on the optical motion capture system,combined with the human gait analysis and kinematics analysis,an evaluation method for the rehabilitation of lower limb fracture of college students is proposed,and the corresponding evaluation and analysis software system is developed in combination with the related technologies such as Motionbuilder,C and database.First,the college students aged 18?25 years were divided into groups according to sex,height and weight.Secondly,the gait test,data collection and data analysis were carried out in order according to the groups.Then a method of evaluating the rehabilitation effect of lower limb fracture corresponding to the medical weight method was put forward.Through the patient's experimental data test,the evaluation method and software system are verified.The main contents of this paper are as follows:(1)Experiment design based on motion capture technology.It includes selection of sample population,crowd grouping,pace grouping,Marker point calibration,and experimental path planning.(2)The design of the data screening program.In order to accurately select the data needed for research and analysis in a large number of data,based on the Microsoft Visual Studio 2015 development platform and the C#programming language,the data separation and extraction program is developed,and the rapid and accurate screening of data is realized.(3)Test gait data post-processing.It includes the output of gait data,the fitting and output of standard data,the comparison between volunteers and standard data and the output,the error analysis of volunteers and standard data,and the comparison and analysis of volunteers and standard data.(4)The establishment and verification of the evaluation method.Based on the previous standard database,a method of evaluating the rehabilitation effect corresponding to the medical weight load method is proposed,and the data collection is carried out to the fracture patients,and the data analysis and drawing are completed.The difference between fracture data and standard data is mainly evaluated,and the difference between them is evaluated.(5)The development of the evaluation system.Based on database technology,user features,Marker point location module and walking frequency data table are created respectively.On the Microsoft Visual Studio 2015 development platform,the software development of lower limb fracture rehabilitation evaluation system based on action capture is implemented by C#programming language.
