Kinesio-Taping and Ankle Instability in Recreational Runners

Running as a recreational sport has been considered a very popular sport that has been practiced by people of both genders and in different age groups. This sport does not need a special place or equipment for practice, this advantage further increased its popularity, as well as, it has a great effect on physical and mental health and decreases the mortality rate by 25-40%. Running is contributing to lowering body fats, reduction of weight, increase of lean body mass, improving resting heart rate, enhancing cardiovascular fitness, and helping in the cessation of smoking.

The incidence of people who practice running as an activity is high in European civilization as it reaches up to 12.5-31% of the population. Recreational runners might be at high risk for running-related injuries as reported 6.3 injuries per 1000 training hours in comparison to 3.4 injuries in the other types of sports activities.

It is worth mentioning that, the prevalence of studies for running-related injuries increases with time. Studies have identified the incidence of injuries extends from 25%-85% in running activities. The ankle joint occupies the second place, after the knee joint, as the most vulnerable joint to injury during running. These numbers indicate the importance of injury prevention and emphasize the methods that help in the reduction of recurrence as it was recorded the average time for recovery is 72 days which means a long period of caseation of all activities and a burden on the economy.

While most of the running-related injuries are either gradually onset or due to overuse, sudden ankle injuries might also occur. One of the most common ankle injuries is the lateral sprains of the sub-talar joint. This injury may lead to trauma to the soft tissues and bony components and consequently affect the function of the injured joint.

Ankle sprain causes a decrease in postural stability and neuromuscular control due to improper somatosensory functioning which is linked to this injury on both sides of the lower limbs either on the affected or non-affected one. postural stability is one of the major functions that depend mainly on the cues originating from proprioceptors. Cutaneous stimulation, especially skin stretching, has been considered as an influential factor in joint proprioception. More accurate joint position sense was reported when the skin was stimulated.

Consequently, any therapeutic intervention which can stimulate skin receptors might have positive effects on the related joint proprioception and may enhance the sensorimotor functioning so it might help lower the risk for ankle injuries.

Kinesio tape (KT) is the application of an adhesive and elastic cotton tape on the skin. This tape is anti-allergic and can be left in place for 3 to 5 days without adverse effects. This therapeutic method has gained increasing interest in the field of rehabilitation and sport. It provides a stretching effect on the skin and may stimulate the cutaneous aspect of the proprioception which in turn may affect the somatosensory function.

A study was conducted with KT on medial tibial stress syndrome which showed a reduction of the loading stress in these patients. This syndrome is usually resulted from repeated microtrauma to the tissues and usually reported in physically active persons as recreation runners. Various studies reported significant improvement in postural control, dynamic, static balance, and improving strength after applying the taping on the participants with ankle instability. Even though, a recently published systematic review reported there is limited scientific evidence regarding the use of KT in the rehabilitation of musculoskeletal injuries.

Exercise is still the best intervention for the treatment of patients with ankle instability as it is designed to stimulate proprioception and decrease the risk of ankle injuries. However, specially designed programs and their preventive effect are still inconclusive and need further research. In addition, there is still controversy in using the KT in the rehabilitation of ankle instability as there was a study that reported no significant improvements in the balance measurements.

Most of the studies are conducted on healthy subjects or athletes but no one takes care of non-athletes who are practicing regular activities as recreational runners, as well as, one of the main components of the prevention of injuries and their recurrence is the building up of awareness especially the increase of the popularity of the taping through different media and the increase of using it during competitive matches. So the purpose of this study is to compare the KT versus special proprioceptive training on the postural stability in recreational runners.
