【摘要】：小腿肌肉在走、跑、跳等基本肢體活動(dòng)中起驅(qū)動(dòng)和控制作用。脛前肌和腓腸肌是小腿肌肉中體積較大的表淺肌,分別負(fù)責(zé)踝背屈和踝跖屈。然而,目前對(duì)二者的狀態(tài)評(píng)估多是從功能角度出發(fā)以功能量表的方式完成,一般忽視了結(jié)構(gòu)信息。此外,小腿肌肉的研究普遍存在研究對(duì)象年齡跨度大,受試者數(shù)量少的問題。與此同時(shí),偏癱是中樞神經(jīng)損傷疾病常見的后遺癥,典型癥狀為足下垂,多由前肌運(yùn)動(dòng)功能受損所致。臨床上常采用電針治療足下垂,然而治療過程中,肌肉的收縮活動(dòng)缺乏量化監(jiān)控,治療的刺激持續(xù)時(shí)間和強(qiáng)度等參數(shù)選擇嚴(yán)重依賴臨床醫(yī)生的經(jīng)驗(yàn)和患者的反饋,易造成治療效果差。鑒此,本文先基于小腿肌肉中的脛前肌和腓腸肌,對(duì)健康青年人在性別、肢體左右側(cè)和經(jīng)常鍛煉與否進(jìn)行了統(tǒng)計(jì)差異分析,發(fā)現(xiàn)脛前肌有較突出的敏感性,之后開展了對(duì)偏癱患者脛前肌在電針治療下的收縮活動(dòng)量化方法進(jìn)行了相關(guān)探索。具體地,本文采用超聲影像技術(shù)采集了健康青年受試者在不同動(dòng)作時(shí)脛前肌或腓腸肌的超聲影像圖,并從中提取了肌肉多種參數(shù),發(fā)現(xiàn)相比外側(cè)腓腸肌,脛前肌對(duì)性別、左右側(cè)、經(jīng)常運(yùn)動(dòng)與否的變化較敏感;對(duì)電針治療下脛前肌量化研究,本文采集了超聲圖像、肌動(dòng)圖數(shù)據(jù)和慣性數(shù)據(jù),從不同角度采用10種指標(biāo)探索脛前肌的收縮活動(dòng),實(shí)驗(yàn)發(fā)現(xiàn),其中6種量化指標(biāo),更加適合用于量化分析電針治療時(shí)肌肉的收縮活動(dòng),它們反映了隨著電針治療,脛前肌收縮活動(dòng)的幅度有下降的變化,脛前肌收縮活動(dòng)的頻率有增加的變化。該變化可望為臨床上電針治療的刺激時(shí)間的設(shè)定提供初步的、量化的信息和依據(jù)。綜上所述,本文對(duì)小腿肌肉收縮活動(dòng)的量化方法探索研究主要分為兩方面:一方面分析了健康青年受試者的脛前肌和外側(cè)腓腸肌因性別、左右側(cè)、經(jīng)常鍛煉與否所存在的差異;另一方面從多種角度探索了電針治療時(shí),脛前肌的收縮活動(dòng)情況。希望本文的工作可幫助從事體育科學(xué)、康復(fù)工程等領(lǐng)域的工作人員對(duì)脛前肌和腓腸肌的了解。
[Abstract]:The calf muscles drive and control basic limb movements such as walking, running and jumping. The tibial anterior muscle and the gastrocnemius muscle are the larger superficial muscles in the calf muscles, which are responsible for ankle dorsiflexion and ankle plantar flexion, respectively. At present, most of the state assessment of the two is done by functional scale, and the structural information is generally ignored. In addition, there is a large age span in the study of leg muscles. At the same time, hemiplegia is a common sequelae of central nervous system injury disease. The typical symptom is foot droop, mostly caused by the impairment of anterior muscle motor function. In clinic, electroacupuncture is often used to treat foot droop, however, in the course of treatment, The lack of quantitative monitoring of muscle contractile activity, the treatment of stimulation duration and intensity of the choice of parameters rely heavily on clinicians experience and patient feedback, prone to poor therapeutic effect. Based on the tibial anterior muscle and gastrocnemius muscle in the calf muscles, the statistical differences of gender, left and right limbs and regular exercise in healthy young people were analyzed, and it was found that the tibial anterior muscles had prominent sensitivity. After that, the quantitative method of contraction activity of the anterior tibial muscle of hemiplegic patients under electroacupuncture treatment was explored. Specifically, In this paper, ultrasonic images of tibialis anterior muscle or gastrocnemius muscle in different movements of healthy young subjects were collected, and a variety of muscle parameters were extracted. It was found that compared with lateral gastrocnemius muscle, tibial anterior muscle was gender opposite, right and left. For the quantitative study of electroacupuncture treatment of lower tibial anterior muscle, the ultrasonic images, actin data and inertia data were collected, and 10 indexes were used to explore the contractile activity of the anterior tibial muscle from different angles. Six of them are more suitable for quantitative analysis of muscle contractility during electroacupuncture treatment, which reflect a decrease in the amplitude of the contraction of the anterior tibial muscle with electroacupuncture treatment. The frequency of tibial anterior muscle contraction has increased. This change is expected to provide preliminary, quantitative information and basis for the setting of stimulation time in clinical electroacupuncture therapy. In this paper, the quantitative research on the contractile activity of calf muscle is mainly divided into two aspects: on the one hand, the differences between the tibialis anterior muscle and the lateral gastrocnemius muscle due to sex, left and right side, regular exercise or not were analyzed. On the other hand, the contractile activity of tibialis anterior muscle during electroacupuncture treatment was explored from various angles. It is hoped that the work of this paper can help the workers in sports science, rehabilitation engineering and other fields to understand the tibial anterior muscle and gastrocnemius muscle.
