Exercise Reduces Symptoms from Fibromyalgia | Central Chiropractor

Fibromyalgia is a mysterious disorder that has been misunderstood for many years, however, there are lots of treatment options available to relieve its symptoms. When it comes to fibromyalgia, exercise can be beneficial to relieve it.

How does exercise help fibromyalgia?
Exercise will be an essential part of fibromyalgia therapy, although your chronic pain and fatigue may make exercising seem excruciating. Physical activity reduces symptoms such as fatigue, depression, and can even help you sleep better. Exercise can be a fundamental part of managing your symptoms.

Exercise for Fibromyalgia
Getting regular physical activity 30 minutes per day, helps reduce perceptions of pain in people with fibromyalgia, according to a 2010 study published in Arthritis Research & Therapy. The signs of fibromyalgia may make exercising a challenge, although exercise is a commonly prescribed treatment for chronic pain.

During a research study, the research team separated 84 minimally active patients…

Snow Sports: Injury Prevention Science


When the northern hemisphere winter approaches, millions head for the slopes. With that in mind, El Paso, TX. Chiropractor, Dr. Alexander Jimenez looks at what recent research has to say regarding injury and injury prevention...

Skiing and (increasingly) ski have become mass-participation sports, appreciated by participants of all ages and skills. Moreover, the popularity of family holidays means that snow sports are not only appreciated by adults, but by younger participants also. Studies have demonstrated that 20% to 30% of snow game participants are children and teens, while an estimated 15 percent of Canadians over the age of 12, and 4 percent of the US population over the age of seven, reported participating in Alpine skiing, cross- country skiing or snowboarding at least one time in 2008-2009(two).

But with increasing snow sport participation comes an elevated rate of traumatic injury as well as the information points to a substantial risk. Figures from US ski hotels revealed that in 2002, an estimated 77,300 ski and 62,000 ski injuries were treated in US emergency departments alone, such as 10,700 traumatic brain injuries(3). Still another study found that snowboarding is responsible for an estimated 25% of non-fatal outdoor injuries requiring emergency care(4).

Studies conducted in a number of countries across Europe and North America have suggested that the risk of injury for skiers and snowboarders is approximately 2 to 4 injuries per 1000 participant times, with the maximum threat in snowboarders(5-9). Children and teens at the 7-17 years age bracket appear to have higher rates of injury than younger and older participants(2).

There is recent evidence that the incidence of traumatic brain injury and spinal cord injury in skiing and snowboarding is increasing worldwide. This growth in severe injuries may be associated with greater risk-taking, such as jumping and acrobatic activities, both on new terrain and in snow resorts/parks specifically made for snowboarding(15).

Typical Injuries Sustained In Snow Sports

A number of reviews have been published that summarize the epidemiology of skiing and snowboarding injuries. Skiers tend to maintain injuries to the lower extremities; snowboarders, on the other hand, are much more likely to sustain injury to the upper extremities (see Figure 1)(16-17). Knee injuries are the most frequent type of injury in ski and constitute around 36% of all ski injuries, according to the literature(18). Snowboarders sustain more ripped ligaments and sprains/strains, brought on by a) position sideways on the board and b) that the absence of a safety binding that opens on its own in the event of a collapse. In a snowboard autumn, the wrists are particularly vulnerable to trauma, especially on impact.


It reported that in Alpine skiing, the most common injury site is the lower extremity (40% to 60 percent of all injuries); knee injuries (eg fractures and sprains) are common and observed more frequently in younger children. Other typical injuries are to the head and neck (10% to 20 percent), upper extremity (15% to 25%), and thumb (10% to 20%). In ski, the most commonly injured site is that the wrist (22%), together with upper-extremity accidents (like wrist injuries) at roughly 50 percent of cases. Of them, 10% required emergency treatment and 30% to 40% requiring following admission for trauma treatment.

Personal details, snow sports-related factors, diagnosis, and treatment have been recorded, and control data were gathered at random from uninjured people at all three areas. A total of 732 accidents were listed at 674 people and the injury rate for the study was 3.7 injuries per 1000 skier days -- very much in accordance with the studies above(5,6,8). Yet again, snowboarders lasted more injuries to the upper limb and axial areas than their skiing counterparts, also ski- boarders and snowboarders also suffered a higher incidence of fracture. Table 1 demonstrates how these injuries were broken down by sport type and anatomical location.

Injury Trends Over Time

Much of the information on snow sports injury was collected in the late 1990s and early 2000s -- coinciding with a time of rapidly growing popularity. But have the injury tendencies changed over time and what would be the implications for injury prevention? A current (2012) US study looked at snow- boarding injury trends at a ski resort in Vermont within a span of 18 seasons (1988-2006) and compared these with Alpine skiing injuries over precisely the same interval(21). The researchers also looked at the differences in injury patterns between snowboarders and Alpine skiers according to age, experience, and sex.

The injury rates were assessed as mean days between injuries (MDBI -- the lower the number, the greater the injury rate). The findings were as follows:

● The average MDBI for all harms among snowboarders has been 345 as compared with 400 for skiers. The most frequent type of harm for snowboarders was a wrist injury (MDBI, 1258), although for skiers it had been an anterior cruciate ligament (ACL) sprain (MDBI, 2332).

● Wrist injuries accounted for 27.6% of all snowboard injuries and 2.8 percent of skiing injuries.

● ACL injuries composed 1.7% of all snowboard injuries and 17.2% of skiing injuries.

● Among snowboarders, more wrist injuries, shoulder soft tissue injuries, ankle injuries, concussions, and clavicle fractures were seen, while skiers had more ACL sprains, medial collateral ligament (MCL) sprains of the knee, lateral collateral ligament (LCL) sprains of the knee, lower extremity contusions, and tibia fractures.

● There was a trend towards an increased incidence of clavicle fractures and a decrease in MCL injuries and ankle injuries among snowboarders over time.

● Skiers had a decrease in thumb metacarpophalangeal-ulnar collateral ligament (MCP-UCL) injuries and MCL injuries of the knee over time.

● The highest rate of injury was among young, inexperienced, female snowboarders.

Overall, whilst injury rates in snowboarders have fluctuated over time, they now remain higher compared to skiers. This may be partly because of changing demographics -- snowboarding is frequently portrayed as a youthful, 'trendy' sport and the data indicates that injured snowboarders were significantly younger, less experienced, and more likely to be female than wounded skiers or snowboard management participants. The growth in rates of clavicle fracture might be connected to a heightened interest in snowboarding acrobatic/airborne maneuvers.

Injury Prevention In Snow Sports

Snowboarding equipment -- Since its inception, snowboarding has always been associated with a higher incidence of upper limb injuries compared to alpine skiing, with the wrist being the single commonest site of injury. In case of a collapse, the natural tendency for a snowboarder is to stretch out (and land on) the hand. Back in 1999, the evidence indicated that less than 10% of snowboarders were utilizing wrist guards to defend the wrist in these falls, despite there being a few epidemiological and laboratory evidence to support their use(22-24). With an increasing emphasis on security, you may think that the situation now is radically different but the evidence is less encouraging.

A 2011 meta-study by US researchers studied all of the published literature about wrist guard use, trauma prevention, the biomechanical effects of wrist guards, and the various kinds of wrist guards commercially accessible for snow- boarders(25). The authors concluded that the use of protective equipment for the wrist is a helpful method for preventing injury. However, they pointed out that while numerous studies looked at the impact of wrist guards, there was no consensus about which particular kind of wrist guard would be most effective; the vast majority of the studies did not mention a brand name or a description of the type of wrist protector that was used by participants. It was also apparent that the literature generally reported low usage of wrist guards by snowboarders -- as low as 6 percent -- possibly because of aesthetics, societal acceptance, match or wrist guard and availability.

Some research has suggested that using wrist guards might increase the possibility of sustaining an elbow, upper arm or shoulder injury -- by transferring the loading during a fall further up the arm. On the other hand, the evidence for this can be conflicting and has not yet been confirmed in a controlled trial or well-designed prospective study and the present best guidance for snowboarders is to use a wrist guard to help avoid injury.

Skiing equipment -- Injury prevalence among skiers has declined over a few decades, largely because of improvements in ski gear, particularly boots and bindings; proof proves that modern bindings decrease the incidence of foot, ankle and lower tibial injuries providing they are properly mounted, adjusted and maintained(26,27). Many accidents are the result of poorly adjusted bindings; in one analysis of adult lower extremity equipment- related injuries it had been determined that in 96% of cases the ski bindings did not release when the accident happened(28). Non-release of bindings has also been reported as an injury contributor in different studies of the two youths and adults. In one study, skiers younger than 13 decades of age with poorly adjusted bindings were much more likely to be injured than children with correctly adjusted bindings(29). Unsurprisingly, therefore, some investigators have proposed that a professional should adjust children's and beginners' ski bindings at the start of every lesson and that these groups should be taught to check their bindings at the beginning of each ski day(30).

Snowboarding and skiing equipment -- One place where there's little doubt over powerful equipment-based harm prevention is helmet use. A new systematic review found that helmets significantly lessen the risk of head injury(31). Skiers and snowboarders wearing a helmet were far not as likely to have a brain injury, and this threat was further reduced when research which included children younger than 13 decades of age were included. Overall, the pooled results showed that helmet use reduces the chance of head injury by around 35%.

Some researchers have raised concerns that while helmet use during skiing and snowboarding reduces head injury rates, it may increase the risk of cervical spine injuries. However, these concerns are not supported by many of case control studies(32-35) and also a 2010 systematic review also concluded that helmets weren't related to an increased risk of neck injury(31). Moreover, there's also no proof that helmet usage in skiing and snowboarding is connected with riskier behaviour (36,37). The obvious conclusion here is that helmet usage ought to be considered compulsory at all times where safety is an issue.

Physical Conditioning: Snow Sports & Injury Prevention

Power, endurance and cardiovascular fitness are all central components in sports injury prevention throughout a vast range of sports, and yet in snow sports, there appears to be a much greater emphasis on equipment-based and third party alternatives. A comprehensive and systematic overview of the literature printed in 2013 looked at injury prevention recommendations specific to recreational Alpine skiers and snowboarders. The attention was to discern recommendations that concentrated physical fitness, exercise and/or training in preventing musculoskeletal injuries in these two sports(38). Studies were included if they dealt with injury prevention, recreational Alpine skiing or snow- boarding and musculoskeletal injuries and articles on elite athletes were excluded.

Overall, 80 recommendations for the prevention of musculoskeletal injuries in recreational Alpine skiers and snowboarders were identified and classified into five main categories:

● Equipment use(n=24)

● Education and knowledge(n=11)

● Awareness and behavior

● Experience(n=10)

● Third-party involvement(n=20)

Amazingly, there was no research that made recommendations pertaining to physical fitness, exercise and/or training per se, or its role in preventing injury! The authors commented thus about the frequent recommendations for preventing ski and snowboarding injuries by an equipment-based or third party approach: "The dominance of equipment-related steps in the injury prevention literature may be rationalized from a sports biomechanics perspective, because these activities involve high velocities and impact forces. Nonetheless, this also suggests a need for proper levels of power, conditioning and endurance to fulfill the technical requirements of the sports." To put it differently, while it makes sense to take precautionary measures regarding proper equipment use, consciousness, behavior etc, neglecting essential physical conditioning could be counterproductive. Unfortunately, there are no peer-reviewed studies about which type of conditioning system is the most suitable for snow sport injury prevention, but some of the general principles that are very likely to be useful are summarized in Box 2 below.

Overview

Skiing and snowboarding by their very nature carry a substantial risk of injury, which could sometimes be serious. The most common injuries are to the knees in skiers and wrists in snowboarders, and the rate of injury is greatest in novices, the less experienced and the young. Along with equipment-based measures, (eg bindings when skiing and wrist guards when snowboarding) is critical for reducing injury risk. Helmet use is also vital to reduce the incidence and severity of head injury in both skiers and snowboarders. In addition a proper pre-skiing/snowboarding conditioning system may also play an important part in ensuring a visit to the slopes is memorable for all the right reasons.

Pain in the Quadratus Lumborum Muscle

A majority of the population have at some point experienced low back pain in their lifetimes. Although low back pain is recognized to result from numerous conditions or injuries on the lumbar spine, muscle strains such as a quadratus lumborum muscle strain, are believed to be a leading cause for the recognizable symptoms of pain and discomfort.
The quadratus lumborum muscle is a sizable muscle in the shape of a triangle, located deep on each respective side of the lower back. The role of the wide muscular tissue is to grant mobility to the lumbar spine in sequence for the torso to move laterally from side to side as well as extend and stabilize the lower spine to improve posture. When this muscle is strained or pulled, the symptoms can restrict movement on the lower back and since the muscular tissue is so extensive, recovery from this type of injury usually requires more time and patience to fully heal.

Achilles Tendon Injury

Achilles tendonitis is a medical term used to describe a condition resulting in irritation of the large tendon, the Achilles tendon. Found in the back of the ankle, this condition is recognized as a common cause for injury among athletes. Excessive use of the Achilles tendon results in inflammation together with swelling and pain.
The development of Achilles tendonitis can be associated with two important factors, most frequently among athletes, which are, lack of flexibility and over-pronation. With age, the tendons will begin to lose flexibility, just the same as other tissues in the body. This change causes the tendons to become more rigid and more vulnerable to injury. For some people, the ankle may roll too far downward and inward with each step they take. This is called over-pronation, which places more stress on the tendons and ligaments of the foot, contributing to injury if not corrected.
Achilles tendonitis may also develop from other factors. An increase in an athlete’s …

5 Common Causes for Shoulder Pain

The shoulders are the most mobile joints in the human body. Because the ball of the humerus is designed to be larger than the shoulder socket that holds it, the shoulders need to be supported by muscles, tendons, and ligaments to secure them in a stable or natural position. Since the shoulder can be unstable, it is often a site for many common complications. Below are 5 common causes of shoulder pain and their associated symptoms.
Rotator Cuff Tear
Rotator cuff tears within the shoulder are a very common type of shoulder injury. The rotator cuff consists of a set of four muscles: the supraspinatus, the infraspinatus, the subscapularis, and the teres minor. All of these muscles are attached to the bones of the shoulders by tendons, which purspose is to support, stabilize, and grant the arm movement to move up, down and rotate. The rotator cuff ensures that the arm remains in the shoulder socket. Damage or injury from an accident or gradual wear and tear can result in inflammation to t…
