Do you know what is a hamstring strain?
The hamstring (Hamstring) is located behind the thigh. It is a group of muscles rather than a single muscle. It consists of three muscles of the semitendinosus, semimembranosus and biceps. One or more muscles are damaged. Pulling the hamstring muscles. The common starting point of these muscles lies in the ischial tuberosity of the pelvis, which spans the knee joint. The semitendinosus and semimembranosus are stopped at the medial side of the humerus, and the biceps femoris terminates at the humeral head outside the knee joint. The main function of the hamstring is to straighten the hip and flex the knee. Acute hamstring damage, from mild to severe, is common in running and hurdle sports. It is also very common in sprint sprints and more sports, such as football and rugby. [Why is there a hamstring strain?] The hamstring strain is more common in sports that require sprinting during exercise. If the treatment is correct after injury, it is easy to relapse and then damage. In acute injury, mainly due to active traction, it occurs mostly in the abdominal abdomen joint, which is most common in the biceps femoris. The hamstrings slow down the swinging calf throughout the start. When the foot is landing, the hamstrings are stretched as far as possible to extend the hips to make the hips straight. This alternates and reciprocates, so that the legs move forward. During the whole exercise, before the foot is hit and hit the ground, the hamstring muscle is pulled up to the maximum extent (close to the longest muscle length), and if it is not well controlled, it is more likely to be injured. In addition, passive stretching exercises, such as leg presses, splits, etc., may also cause acute strain on the hamstring. Chronic injury is more common in exercise, after repeated traction, and acute injury is not treated properly, repeated attacks. [What are the typical symptoms of hamstring strain?] Most cases occur in sprints or high-speed running, and sudden pain occurs behind the thighs; Pain occurs behind the thigh during knee extension and flexion; Swelling and bruising appeared locally behind the thigh; If a severe tear occurs, a partial depression can be felt on the muscle belly. [How to know if a hamstring strain has occurred] It is generally difficult to detect hamstring damage or tear by simple palpation. If you just feel that there is discomfort in the back of the thigh after exercise, and you are not aware of the possible hamstring damage, it is easy to be mistaken for a simple soft tissue contusion. If there is obvious pain in the back of the thigh after exercise and there are symptoms similar to the above, it is recommended to seek medical advice promptly. Depending on the location of the pain, the doctor will usually allow the patient to carry a leg straight leg pull and an anti-obstruction knee test. If it can induce pain behind the thigh, it can help diagnose. Professional sports trauma doctors will combine the patient's medical history and physical examination to make a comprehensive judgment. Imaging studies include B-mode or magnetic resonance imaging (MRI) to help identify the location of the injury. Sometimes, the pain behind the thigh is not a simple hamstring injury, and it is easily confused with diseases such as groin-adductor injury, sciatica, ankle pain, and hip bursitis. Prompt medical treatment also helps to rule out the possibility of such diseases. [Which factors may increase the risk of hamstring injury] Age: Older people, hamstrings are more susceptible to injury when pulled; History of injury: patients with previous hamstring and muscle injury are susceptible to injury again; Flexibility: Studies have shown that people with better flexibility in hamstrings are less susceptible to damage; The hamstring muscle strength: related research found that the hamstring muscle strength is relatively easy to damage; Lumbar plexus plexus compression: The compression of the L5-S1 plexus can cause fatigue of the hamstring muscle and easily induce injury; Fatigue and adaptability: When an athlete experiences fatigue, some of his muscle groups lose mutual coordination. At this time, the two heads of the hamstring muscle are dominated by different nerves because of the two parts of the hamstring muscle, and the original synchronous coordination effect is easily lost in the fatigue, and finally the hamstring muscle is torn. [How to treat hamstring damage] It is very important to start treatment immediately after the hamstring injury. The best time to treat is within 48 hours of the injury. 1. Emergency treatment (FirstAid): Stop any exercise immediately and reduce the muscle pull on the back of the thigh Ice injury is about 15-20 minutes, every 2-3 hours (depending on the situation), lasting 1-2 days, until the swelling and pain gradually improve An elastic bandage can be used to properly secure the injured thigh to prevent further swelling; or to use the intramuscular sticking method for swelling A soft pillow under the leg, raising the injured limb Severe pain or even paralysis, can take NSAIDs anti-inflammatory analgesics and muscle relaxants under the guidance of a doctor If the pain can be tolerated, straighten the knee as much as possible, so that the injured muscle is in the extension position to prevent scarring. 2, regular processing: Timely medical treatment Severe pain, under the guidance of a doctor, can continue to take NSAIDs anti-inflammatory analgesics and muscle relaxants. If there is no further guidance from a doctor, elderly people over the age of 65 should not take NSAIDs for anti-inflammatory painkillers for more than 7 days. Affecting the pain of walking, it is recommended to use crutches; Physical therapy, treatment of injured muscle tissue with ultrasound or microwave; Rehabilitation training, early activity injured lower limbs is an important one in the correct rehabilitation program. This includes stretching and strength training within the limits of pain. This type of exercise helps to relieve local tissue swelling. The risk of secondary injury can be reduced through reasonable training; Sports massage can speed up muscle recovery and is very important in the healing process of injuries. Because massage can destroy collagen, rearrange normal fibers, minimize scar tissue, and increase blood circulation in the damaged area. It is recommended to use intramuscular protection when exercising. Conservative treatment is generally used. Severe hamstring breaks can be considered for surgery to repair damaged tissue During the recovery phase, it is recommended that you change the previous exercise and activity to avoid exacerbating or recurring the injury. For example, you can replace the original running sport with swimming. [How long does it take to resume normal activities?] How long it takes to recover depends on many factors such as the age of the injured person, the rehabilitation status, and whether there has been a history of hamstring damage. It also depends on the degree of damage. Mild hamstring damage can be recovered within a few weeks, while severe injuries can take up to 6 weeks or even longer to recover. During the recovery of the treatment, stop all activities that may cause hamstring pain, otherwise the symptoms may be repeated. The movement of people, the time to resume exercise after injury, due to individual differences, but also different, mainly depends on the activity and strength recovery of the hamstring muscle. Generally, before the regular treatment, the longer the symptoms last, the longer the recovery time. The goal of rehabilitation is to be able to return to exercise as safely as possible, rather than as fast as possible. How to safely resume exercise can be judged according to the following enumeration: Compared with the healthy side, has the full activity been restored? Compared with the healthy side, has you recovered enough muscle strength? When walking straight ahead, there is no pain or discomfort, no limp. [How to prevent hamstring damage] One of the more important ways to prevent hamstring damage is to warm up properly before exercise. It has been shown to be effective in reducing the risk of hamstring damage. Warm-up exercises include a moderate amount of aerobic training. The stretching and strength training rehabilitation program specially designed for the hamstring muscle group can effectively reduce the risk of injury in the application of sprinters and high-speed sports. By distinguishing between muscle tension points and weakness points, regular deep tissue exercise massage relaxes to help prevent muscle strain. Wear tight-fitting warm pants during winter sports to reduce the risk of injury. TV Stand, mirrored tv cabinet, modern tv stand Hongsing Glass Hardware Porduct Co Ltd , https://www.hongsingglass.com
