What is MS?
Multiple Sclerosis (MS) is a neurodegenerative disorder of the central nervous system (CNS) caused by immune system imbalance. The principal consequence is damage and/or destruction to the myelin sheath, the protective coating that insulates nerve axons throughout the body. This causes axon damage and disruption to or loss of electrical signalling within CNS. While there are 4 principal types, relapsing-remitting is by far the most common (85% of cases). It is characterised by attacks of symptoms (‘relapses’) then a period of remission. Over time, there is usually progress into the other 3 more 'progressive' forms of the disease, characterised by a gradual worsening of symptoms. Eventually all forms of the disease lead to an accumulation of irreversible neurological deficits.
Prevalence and risk factors associated.
An estimated 2.5 million individuals suffer from the disease worldwide and it at least twice as common in females than males. The exact cause of MS is not known, but some of the main risk factors identified include genetic predisposition (a range of different genes have been linked), vitamin D deficiency, and smoking.
- Loss of muscle strength and tone.
- Loss of balance and coordination .
- Numbness, tingling and tremors.
- Decreased functional ability.
- Increased fatigue.
- Sensory disturbance (often heightened).
- Bladder and bowel dysfunction.
- Loss of motivation and concern about being involved in social activities.
- Decrease in general quality of life.
While there is no known cure, a range of pharmaceutical and non-pharamaceutical interventions are recommended. These will vary depending on the form or the disease and severity of the symptoms. However common treatment involves at least one or all of the following:
- Pharmaceuticals – Used to:
- Slow severity and frequency of relapses.
- Aid with inflammation.
- Diet – A balanced and healthy diet is recommended to increase energy levels.
- Exercise and lifestyle interventions – aerobic and resistance training to help prevent disability progression.
Resistance training is a form of exercise generally used to strengthen skeletal muscles. In MS patients, it has been shown to be effective in slowing disability progression of the disease and may be particularly useful in targeting specific symptoms, such as generalised muscle weakness.
- Improving muscle strength.
- Improving balance/coordination.
- Increasing functional capacity.
- Decreasing fatigue.
- Encouraging social interaction.
- Improving mood, feelings of wellbeing and quality of life.
- Train all major muscle groups at least 2 times per week.
- Slowly build up to 2 sets of 10-15 repetitions.
- Use weights heavy enough that repetitions can only just be completed.
- Rest for at least 1 day between sessions.
- Weight machines, free weights, cable pulleys, elastic resistance bands or bodyweight may all be used.
- Program should be individualised depending on severity of symptoms and disability.
- Exercise program should be designed by a qualified health professional and progress should be frequently reviewed.
- Potential interaction with medications should be considered.
- Exercise in an appropriate environment - due to decreased ability to thermoregulate, exercise should be undertaken at cooler parts of day and appropriate clothing/footware should be worn to encourage ventilation.
While MS can be a physically and mentally debilitating disease, exercise, and in particular strength training, has been shown to drastically help improve some of the associated symptoms and help slow disability progression. As long as patients follow a properly designed program catered to their individual case, they should look forward to a range of positive benefits, including improved muscle strength, functional capacity, and decreased fatigue.
