Physio Health Advice > Shin Splints
What is it?
Medically known as Medial Tibial Stress Syndrome, shin splints is a term used to refer to pain along the inside of the tibia or shin bone. The exact pathology that causes the pain of shin splints is unclear and imaging such as ultrasound produces similar results when compared to persons who don’t have shin splints. The pain of shin splints is usually felt over the area where two particular muscles insert into the tibia. These are Tibialis Posterior and Flexor Digitorum Longus, these muscles act to extend the foot and toes respectively.
Despite having an unclear pathology, this can be a debilitating condition that can impact activity levels significantly. The pain can be quite limiting and may even be an early warning sign of a stress fracture and this will need to be ruled out by a medical professional.
What are the symptoms?
Shin splints are typified by persistent leg pain, usually the inside of the shin, halfway down the lower leg. The pain might be felt during exercise or directly after. Some people experience a dull ache over their shin that lasts for quite a while after exercise stops, while for others the pain may be sharp and fades quickly.
The pain is often progressive, becoming worse with shorter distances. Eventually shin splints can severely impact activity levels as the pain becomes too severe to continue exercise.
What are the causes?
Shin splints are predominantly seen in runners who increase their distances quickly, often while training for an event. Activities that require repetitive weight bearing of any kind, such as marching or high impact sports have also been shown to cause shin splints. Although the pathology of shin splints is unclear, studies have been able to identify certain risk factors that may predispose someone to shin splints. These include;
- An abrupt increase in activity level
- Improper foot wear and support
- Higher BMI
- Training on hard or uneven surfaces
- Tight calf muscles
- Flat feet
- Increased external rotation range of the hips
- Females are more likely to develop shin splints than males.
- Prior history of shin splints
- Wearing or having worn orthotics
How can physiotherapy help?
The first step for your physiotherapist will be to address any contributing factors and
help to adapt your training program to a level that is optimum for you. A period of relative rest may be recommended along with a targeted strengthening and stretching program for any tight or weak muscles.
Switching to low-impact activities such as swimming, cycling and yoga may also help to maintain fitness during recovery. Your running technique will be analyzed and any training errors may be corrected. When getting back into your training routine, it is usually recommended that distances are not increased by more than 10% per week as this allows the tissues of the body to react to the increased demands and adapt accordingly.
