Abstract

This paper aims to evaluate the clinical curative effect of wrist-ankle acupuncture combined with Ashi acupuncture point for the treatment of muscular strain in aerobics athletes and to provide scientific reference for future clinical treatment. 190 aerobics athletes with muscle strain treated in our hospital from March 2014 to March 2016 were randomly divided into two groups according to the random double blind method. The 95 patients in the observation group were treated with wrist-ankle acupuncture combined with Ashi acupuncture point, while the patients in the control group received body acupuncture alone. The improvement of muscle strain was compared between two groups and effective rate of treatment was evaluated. The average time of improvement in muscle strain was (3.75±1.23) d for the observation group and (6.17±1.42) d for the control group. Comparison between the two groups (p<0.05) was with significant statistical significance; the overall effective rate was 98.95 % (94/95) in the observation group and 90.53 % (86/95) in the control group. There was significant difference between the two groups (p<0.05). However, the cure rate was 81.05 % (77/95) for the observation group, but 60 % (57/95) for the control group. Comparison between the two groups (p<0.05) was with significant statistical significance. Wrist-ankle acupuncture combined with Ashi acupuncture point can effectively shorten the wound healing time and improve the cure rate of muscle strain, which has high clinical application and popularization value.

Aerobics is a new sport in recent years, in which the athletes complete a variety of actions with rhythmic music accompaniment in order to achieve the purpose of fitness, body building and health. Aerobics training objectives and action requirements are different, which are divided into public fitness and athletic body building. Public fitness gymnastics has lower requirement for action, smaller exercise intensity and load. However, athletic gymnastics requires a high degree of movement, with smaller exercise intensity and load and anaerobic functional metabolism as the main. But both need basic quality such as flexibility, sensitivity, strength as a guarantee and so they are more prone to sports injuries. The statistical results show that injury rate of gymnastics is about 58.72 % due to poor technical level, excessive physical activity and environmental factors, while muscle strain is the most common injury except for joint sprain and ligament injury.

Muscle strain (fig. 1-3) is a muscle injury caused by sharp contraction or excessive traction in the movement. It can be easily caused in trample, chin up and sit ups exercises[1]. After muscle strain, the strain parts suffer sharp pain, one can touch block like lumps with significant pain due to muscle tension. Due to local swelling or subcutaneous bleeding, activity will be significantly limited. In sports, due to improper preparation, physiological function of a part of muscle has not yet reached the required state to adapt to the movement; training level is not enough, muscle flexibility and strength is poor; fatigue or excessive load results in muscle function decline and weakening and reduced coordination; wrong technical action or no concentrated attention during exercise, overexertion or roughness; too low humidity and too much humidity, poor quality of the site or equipment can lead to muscle strain.

Clinical treatment of muscle strain usually follows basic principles of relieving pain, preventing stasis, promoting menstruation, laying bones, expelling wind and removing cold. Ashi acupuncture point therapy is a very common treatment method. But according to research results of Zhou Bencheng, Shenjian, cure rate of Ashi acupuncture point was only 61.3 % for muscle strain in aerobics, which cannot meet the requirement of restoring patient’s physical activity ability as soon as possible[2]. Therefore, in our study, our hospital tried to combine Ashi acupuncture point therapy with wristankle acupuncture therapy, in order to further improve the cure rate.

Materials and Methods

General Information

The subjects of this study were 190 cases of aerobics athletes with muscle strain treated in our hospital from March 2014 to March 2016, who was randomly divided into two groups with double blind method, each group with 95 cases. The observation group consisted of 42 males and 53 females aged between 12 and 26 y. The course of the disease ranged from 0.5 to 13 d. The control group consisted of 44 males and 51 females aged from 11 to 27 y. The course of the disease ranged from 1 to 15 d. The two groups were in line with the clinical diagnosis of muscle strain (fig. 4 and fig. 5). The injury sites included 10 cases of back muscle, 18 cases of shoulder muscle, 42 cases of gastrocnemius, 27 cases of sartorius muscle, 34 cases of popliteus muscle and 59 cases of quadriceps femoris, which were evenly distributed among the two groups (Table 1).

Inclusion and exclusion criteria[3]: Have a history of significant sports injury; partial muscle pain, tenderness, swelling and subcutaneous bleeding, resistance pain (+); some patients may have palpable block like mass, with accompanying tearing of muscle fascia; patients with complete rupture of muscle fascia and presence of other types of injury were excluded; all patients were willing to participate in treatment research and signed informed consent and the relevant information was approved by the Ethics Committee.

Therapeutic method

The control group was treated with body acupuncture only. For acupuncture of strain site, neck and shoulder include Yanglao, Jian Jing, Dazhui, neck and back include Tianzong, Xuanzhong, anterior part of chest includes Neiguan through Wai kuan, lateral thorax part includes Taichong, center of the waist includes Renzhong, both sides include Yanglao, lateral thigh includes Zusanli, Yanglingquan, posterior leg includes Feiyang. For a large area of strain, add 4-6 needles at upper and lower, left and right edge of the pain zone[4]. Lift and pull to produce a sense of needle, manipulate needle once every 5 min, each treatment lasts 30 min, once a day. Every 3 d represent completion of a course of treatment.

The observation group was treated with wrist-ankle acupuncture combined with Ashi acupuncture point. First, find the most painful point in the affected side of the patient, that is, Ashi point. Conduct routine disinfection for local skin and choose appropriate needle according to the injured muscle depth, generally 50-75 mm in length. Pierce the pain center, lift, thrust, swirl and rotate for 1 min after arrival of qi[5]. And then select acupoint by referring to the wrist-ankle acupoint selection method based on the injury site, take upper 4, 5 acupuncture of the affected side of the shoulder; take upper 5 acupuncture of the affected side of the elbow; take upper 5 acupuncture of the affected side of the wrist; take double lower 5,6 acupuncture of the waist; take lower 3, 4 acupuncture of the affected side of the knee; take lower 5 acupuncture of the affected side of the lateral malleolus; take lower 2 acupuncture of the affected side of the malleolus medialis. Before treatment, conduct routine skin disinfection and then select No. 30-32, 30-40 mm long stainless steel needle[6], make a 30º angle between the needle body and the skin surface, slightly spin the needle and quickly penetrate it into the skin and then lay the needle flat, point the needle to the lesion, gently push the needle along the skin about 2.5 cm until needle protrusion can be seen on the body surface. When pushing the needle, the doctor should not have a sense of resistance in the fingers, the patient should not have acid, hemp, swelling or heavy pain feeling, otherwise, withdraw the needle to repenetrate it. Retain the needle for 30 min[7], generally no hand manipulation of needle is needed during needle retention. For some patients, to enhance the analgesic effect, scraping needle approach can be used. Treat once daily and for 3 d represent the course of treatment.

Clinical observation indicators

The time of improvement in muscle strain in the two groups was recorded in detail and the effect was further determined according to the symptoms, palpation examination, functional recovery and the actual situation of the patients[8,9]. Invalid: After 15 times of treatment or more, there was no significant relief of symptoms, patient could not carry out daily training. Improved: After treatment, pain, swelling, tenderness was relieved, but the functional recovery was poor, patient could not engage in training of moderate or above intensity. Markedly: After treatment, pain was significantly reduced, swelling and tenderness subsided, function basically recovered, there was no or only mild symptoms during rest, symptoms slightly heightened after training, patient could not engage in high intensity training in daily training, but moderate intensity training was allowed[10]. Cured: After treatment, pain and local tenderness disappeared, swelling subsided, function recovered, routine training was as usual and patient could carry out normal moderate, high intensity training.

Statistical methods

In this study, the clinical effects of wrist-ankle acupuncture combined with Ashi acupuncture point in treatment of muscle strain of aerobics athletes were analyzed. The data was analyzed and processed with SPSS 19.0 statistical software. The count data were expressed as (n, %) and tested by chi square, while the measurement data was expressed as (x?±s) and tested by t. The difference was statistically significant only if p<0.05 was satisfied.

Results and Discussion

The average time of improvement in muscle strain was (3.75±1.23) d for the observation group and (6.17±1.42) d for the control group. The difference between the two groups (t=12.555, p=0.000<0.05) was with significant statistical differences (Table 2).

From the perspective of traditional Chinese medicine, muscle strain belongs to “injured tendon”, a symptom of damaged muscle meridian and collaterals. The main pathogenesis is adverse muscle meridian, blood barrier. For treatment, it is better to activate blood and remove stasis, promote qi circulation to relieve pain. Ashi point is the main point of pathological response. Based on principle of adjacent acupoint selection, to stimulate the point, we can activate blood, remove stasis and clear the meridians, so it is more commonly used[12].

Wrist-ankle acupoint is a subcutaneous needle retention method, which works mainly through stimulation of twelve skin areas which are corresponding parts of twelve meridians function reflected in the body surface, also area with collaterals distribution. The stimulation of twelve skin areas can regulate twelve meridians, dredge the meridians, regulate qi and blood and stimulate channel qi running of the skin. Wrist-ankle acupuncture, through the neural and humoral regulation and the combined effect of a variety of automatic control systems of the living organism, can mitigate spasm of the lesion site, improve local blood circulation and nutrition of injured limb and promote absorption of edema and inflammation to achieve analgesic effect. As this method features less acupoint selection than pure acupuncture, slight pain and does not need soreness which is required by general acupuncture, it enjoys greater advantages in clinics. The study results showed clear advantage in treatment effect of observation group compared with the control group. Also, time of improvement in muscle strain was significantly shorter than that of the control group, which further demonstrated effectiveness of Ashi point combined with wrist-ankle acupuncture.

In summary, wrist-ankle acupuncture combined with Ashi point for muscle strain in aerobics can effectively improve the treatment efficiency, which enjoys greater advantages in efficiency and cure rate compared with simple body acupuncture treatment. Hence, it is recommended that this combination therapy can be widely used in clinics.
