Can Dry Needling Help Stabilize A Sprained Ankle?
Understanding Ankle Sprains and How Dry Needling Can Help
As any athlete knows, twisting or turning your ankle can be one of the most painful and frustrating things that happens during athletics. And ankle sprain can literally change your ankles structure, making it weaker and more unstable, even changing the alignment of the joint, which can lead to more sprains in the future. Any athletic endeavor is susceptible to ankle sprains. Anything that causes quick movements, jumping, and high joint reactive forces places the ankle at risk. Even worse, spraining your ankle once makes it far more likely that you will sprain your ankle again. In fact, according to one research article, 70% of basketball players who have sprained their ankle will sprain it again within 6 weeks to 18 months.
Recurring sprains can lead to a condition known as chronic ankle instability. If the ankle has not been protected and rehabilitated properly, joint laxity will occur due to weakened ligaments, tendons, and muscles. This makes balance more difficult and decreases the reactivity of the joint, making repetitive sprains more likely.
How Does CAI Affect Muscle Control?
In particular, people with chronic ankle instability may develop motor control issues in specific muscles such as the fibularis muscles (also known as the peroneal muscles) as well as the tibialis anterior muscle on the front of the shin. These muscles may not react in the proper sequence or at the primer time, and this delay increases the risk of injury, especially when jumping, cutting, and landing.
In Rehabilitation literature we have found that one of the reasons for this is because myofascial trigger points (MTrPs) develop which hinders normal muscle function. These trigger points are usually small, sensitive areas within muscles that may or may not be painful. Trigger points can be thought of as a protective mechanism due to localized dysfunction. Normal functional patterns are down regulated in the body’s attempt to protect against further injury, and trigger points play a big role.
If you have spent any time at all on this blog you know that Dry Needling (DN) is used by physical therapists to relieve myofascial trigger points, decrease muscle tightness and stiffness, and improve overall joint function while also decreasing pain..
The Goal of the Study
This study aimed to find out whether DN could help basketball players with CAI by improving muscle activation and balance. Specifically, researchers wanted to see if DN would increase muscle activation before landing from a jump (pre-activation) and if it could improve balance during a one-legged test. They also wanted to understand if DN could reduce the amount of sway (side-to-side movement) when balancing.
The researchers believed that Dry Needling would help these athletes by reducing the activity of trigger points, which could lead to better muscle activation and improved balance. If the study’s results support this idea, it could mean that Dry Needling is a valuable treatment for athletes with CAI.
To study the effects of dry needling on basketball players with a history of chronic ankle instability, the researchers chose an experimental group and a control group. The experimental group consisted of those basketball players who would receive actual dry needling. A trained physical therapist would treat the athlete by locating the most painful trigger points. He or she would choose a trigger point in the fibularis or anterior tibialis muscle, insert a needle into those points, using a specific technique to trigger a response in the muscle. For the control group, the athletes would receive Placebo dry needling. This entails the physical therapist penetrating the skin but not actually piercing the muscle, ensuring there would be no response triggered within the muscle.
Here’s what the researchers found:
- Muscle Pre-Activation: Basketball players who received the Dry Needle treatment demonstrated significantly improved responsiveness of these stabilizing muscles that better prepared them for impact when landing.
- Balance and Sway: The researchers found that the basketball players who received the dry needle treatment had significantly less “sway” when balancing on one leg.
Clinical Implications: These findings Demonstrate that dry needle therapy can offer significant help to athletes with chronic ankle instability. Athletes who have a history of previous ankle sprains typically demonstrate decreased balance and reactivity of joint awareness and control which places them at higher risk for repeat injury. Studies such as this one demonstrate that dry needling improves muscle activation as well as postural control. Both of these are important in helping to reduce the risk of future injury.
So have you been struggling with an unstable ankle that causes you movement limitations or pain? It’s not too late to make a change! Dry needling, when performed by a qualified physical therapist, presents a promising approach for improving ankle mobility and function as well as reducing discomfort. This along with treatments like frequency specific microcurrent can make significant changes in your ankle joint motion and function. Do you think this could be a good fit for you?
