To the skier, the thought of watching friends and family clumping off in their boots towards the lift whilst sitting with a leg up, packed with ice and the daily paper, is intensely frustrating. Injuries happen. In many cases with the right early treatment, perhaps surgery and definitely a thorough rehabilitation programme, the symptoms resolve and the leg works again, good as new. However, there are a number of cases when this does not follow suit and the pain and limitations continue. There are reasons for this occurrence and they extend beyond the health of the tissues that almost always go through a healing process.
There are some complex mechanisms at play in the nervous and immune systems that are really useful when we first have an injury. This of course includes pain that is part of the way the brain defends the body when we damage ourselves. The way in which we go about protecting and treating ourselves is driven in part by the pain that motivates these actions: rest, seek advice or take analgesia. That is what pain really is, a motivator to take action to promote healing and survival. In the early stages of having injured tissues, often ligaments at the knee, this is really useful and important. Briefly, the damaged tissues release chemicals that sensitise the local nerve endings, stimulating a volley of danger signals to be sent to the spinal cord. Here, secondary neurons send this information to the brain for scrutiny. On deeming there to be a threat, the brain engages protective responses including pain, changes in movement and healing. Sometimes we can injure our tissues and the brain decides that something else is more important, perhaps escaping from the mountain, and will send signals down to the spinal cord to interfere with those coming from the tissues. The end result is the feeling of no pain and therefore you can take yourself to safety. Then it can start hurting. All in all, the responses will vary as will our ability to cope.
The early bombardment of the spinal cord and brain with danger signals that can also be influenced by the context of the injury, e.g. really scary, leads to changes in the properties of the neurons in the spinal cord. This means that subsequent signals can be amplified. It also means that normal signals (e.g. light touch) can start to provoke a painful response as can areas not directly involved. In the latter case one can find that the area of pain grows (click here). The on-going activity in the nervous system and other systems such as the immune system, endocrine system and autonomic system underpin the experience of persisting pain and protection, including altered movement that is so important to normalise.
In the case that the problem persists, the treatment is different. The tissues are addressed as one would expect with manual therapy, massage and other local treatments. However, alongside these traditional techniques are a range of strategies and treatments that are based upon the latest pain sciences that target the changes aforementioned and others. These strategies target the mechanisms at play and at source reduce the threat and hence the pain, normalise motor control and sensation of the affected area and restore function so that there can be a progression back to pre-injury activities.
