If you are an athlete of any kind then it is likely that you have experienced a very painful ankle sprain or strain. This is a highly common injury within court sport athletes. Compex can aid you by preventing this type of injury from occurring and also assisting in recovery if you have experienced an injury.

So how can the use of a Compex muscle stimulation device help?

First of all we need to take a look into the anatomy. This will give you a clear understanding of how the body works, what you need to target and why.

Ankle Twist Prevention with Compex

Anatomy of the Ankle

The peroneus muscles also called fibularis muscles or peroneals or peronæus, are a group of muscles in the leg. The muscle group normally consists of three muscles: peroneus longus, brevis, and tertius, although it exists in many variations.

These muscles help control key actions around the foot. They will need to be strong and robust allowing you to resist and control the very actions they allow you to perform. Something that the use of a Compex device can enhance whilst training. The reason that the use of Compex is highly effective with this set of muscles is that they are very difficult to activate.

So where are these muscles located and what do they do?

Lower Leg Muscles

Ankle Strengthening and Injury Prevention

You can train these muscles either statically or through a range of traditional ankle mobility, stability, and strengthening exercises. You can do this by placing Compex electrode pads on the peroneus muscles and selecting frequencies between 45-70Hz. This will help to increase muscle volume similar to that experienced whilst training for hypertrophy by promoting optimised tissue formation.

Once you have completed a period of adaptation for increasing muscle volume, typically lasting 6-10 weeks, then you can move into a strength phase for a similar length of time. This requires your muscles to be exposed to frequencies between 75-100Hz.

Completing these two phases routinely will continually allow for the peroneus muscles to increase in volume and strength. This makes you more stable and helping you to prevent ankle sprains and strains.

Acute Injury Management and Rehabilitation

If you have experienced an ankle injury, it would have stretched, strained, and damaged the peroneus muscles along with tendons and ligaments around the foot and ankle.

The use of a Compex device can not only aid with strengthen the muscles as highlighted above. They can also aid the recovery process.

During the initial phase of recovery, dealing with inflammation, Compex can help to reduce muscle soreness (1Hz). Additionally, muscle pain can reduce (5Hz) and capillarisation increased (8Hz). These varying levels of increased blood flow will help improve the supply of oxygen and nutrients to the damaged region. During this phase it is recommended to place the electrode pads around the site of the injury (ankle and foot) rather than the peroneus muscles unless major trauma has also occurred in this area.

During the second phase of recovery with Compex, the profilation phase, frequencies between 10-35Hz can help minimise stiffness. You can minimise muscular atrophy while managing lingering discomfort and swelling..

Once the symptoms have subsided, it is time to start remodeling the muscular tissue within the affected area, similar to any traditional rehabilitation process. Firstly by increasing muscular volume (45-70Hz). Then by increasing strength (75-100Hz) which are both mentioned in more detail above in ‘Strengthening and Injury Prevention’.
