    摘要:

    目的:利用运动捕捉技术量化摇拔戳手法治疗外侧踝关节扭伤的运动学操作特征,为手法的规范化操作及教学传承提供客观依据。方法:由专业的医师在60例外侧踝关节扭伤的受试者上进行摇拔戳手法治疗,在手法操作过程运用运动捕捉系统软件提取有效的运动学指标来进行分析和总结规律。结果:获得了摇拔戳手法的运动学参数量化值:将踝关节摇转6周的平均用时为11.36s;对踝关节实施拔伸和戳按手法各1次,两手法的平均用时为3.42s;对踝关节实施拔伸手法后其位移的平均值为36.94mm,戳按踝部后位移的平均值为22.44mm;将踝部拔伸时运动角度的平均值为23.27°,将踝部戳按时运动角度的平均值为22.76°;摇拔戳手法治疗过外侧踝关节扭伤时,踝关节摇转时的线速度平均值为58.28mm/s,对踝关节实施拔戳手法的线速度的平均值为23.81mm/s;将踝关节摇转时的线加速度值为0.43mm/s2,拔伸戳按踝关节的线加速度值0.54mm/s2。结论:摇拔戳手法可应用推广于临床,在操作时应遵循“顺势而为、和缓匀速、连续进行”的原则,在遵循踝关节生理特点的前提下,缓慢匀速的对扭伤的外侧踝关节连续进行摇拔戳手法治疗。

    Abstract:

    Abstract Objective:Motion capture technology is used to collect the kinematic parameters of the ankle roating-traction-poking manipulation (RTPM), analyze the operation characteristics of the manipulation and summarize the rules for the technique can be more consistent with the norm, which could lay the root for education inheritance and clinical promotion. Methods:A total of 60 volunteers who had ankle sprains participated in the study. A single physiotherapist specializing in RTPM worked with each of the subjects. Motion capture technology were used to acquire kinematic data during the RTPM. Results: The average time of rotating for six circles was 11.36s and the average time of pulling and thrusting once per ankle was 3.42s. The average value of the traction was 36.94mm and the average movement of the poking by the ankle was 22.44mm. The average angle of motion of the traction ankle was 23.27°, the average poking angle by ankle was 22.76°. The average linear velocity of the ankle joint was 58.28mm/s during the ankle RTPM, the average linear velocity of ankle traction-poking was 23.81mm/s. The linear acceleration value when the ankle joint was rolled was 0.43mm/s2 and the linear acceleration value of the ankle traction-poking manipulation was 0.54mm/s2.Conclusion: The RTPM can be applied repeatedly in clinical practice and also has features of gentleness, rhythmicity, and continuity.Under the premise of following the physiological characteristics of ankle joint, the treatment of the sprained ankle should be carried out with slow and uniform speed continuously.
