Editor’s note: Tamara Sellman continues her occasional series on the MS alphabet with this column referencing terms starting with the letter P. This post comes fourth in a series of seven.
Symptoms of MS
Tremors (specifically, cerebellar tremors) are a common symptom of MS. A postural tremor basically refers to any kind of tremor that occurs while one is upright (either sitting or standing). It can also happen any time you extend a limb outward and hold it against gravity.
Tremors occur because of lesions in the cerebellum, which is the part of the brain and central nervous system that regulates nerves that signal and coordinate motor movements.
PT (physical therapy)
Physical therapy is a proactive, nonpharmaceutical approach to treating symptoms of MS involving movement. PT encompasses a broad range of therapeutic activities to provide relief and support, such as:
- Improving balance (and preventing falls).
- Improving coordination of hands and arms, and legs and feet for more efficient movement.
- Improving control over physical effort to improve daytime energy.
- Providing safe modifications for physical tasks no longer performable in the usual way.
- Improving overall muscular strength.
- Providing relief from pain and fatigue in muscles.
- Learning new stretches to ease or prevent spasticity.
- Improving range of motion.
- Learning to safely and effectively use assistive devices.
- Providing ways to overcome specific MS symptoms like foot drop.
- Assisting with assessments when applying for disability.
Common MS terms
This word is used to describe one’s disease course when they have MS. Progression might be measured by the number of exacerbations (or relapses and flare-ups), but not always. It depends on the type of MS diagnosis.
To better understand progression, it’s important to differentiate between the five key forms of MS.
Clinically isolated syndrome (CIS) is MS that doesn’t progress.
Relapsing-remitting multiple sclerosis (RRMS) shows progression during relapses (periods of exacerbation or “flares”). There is no progression during remission, which is considered a recovery period.
Primary progressive multiple sclerosis (PPMS) progresses without any obvious pattern of flare-ups or recovery.
Secondary progressive multiple sclerosis (SPMS) begins as RRMS, but over time, the symptoms grow steadily worse in a steady disease course that most resembles PPMS.
Progressive relapsing multiple sclerosis (PRMS) gives the appearance of PPMS at first, but symptoms steadily worsen, and exacerbations can also occur independently, with or without a remission period.
The biology of MS
The plantar reflex happens when an instrument, stroked across the side of the sole of the foot, produces a reflex response in the big toe. This is considered normal. When the reflex response does not happen as expected, it is termed an extensor plantar reflex (otherwise referred to as Babinski’s sign).
Conducting this sensory test is common among neurologists who are looking at reflexes to check brain function. In the case of an abnormal plantar reflex test, results suggest problems in the pyramidal tract of the brain, which is related to MS.
This alertness-promoting medication is used off-label to treat MS fatigue. Initially developed to treat narcolepsy and idiopathic hypersomnia, Provigil (modafinil) is also used in people with sleep disorders such as sleep apnea and shift work disorder (a kind of circadian disruption related to working at night).
Provigil is not a stimulant, per se. Its chief function is to improve the brain’s regulation of a wakefulness neurotransmitter called hypocretin (also referred to as orexin).
This medicine belongs to a class of medications popularly referred to as “performance” medications, or nootropics. It is labeled with a “black box warning” as a federally controlled substance (C-IV), due to risks with abuse and dependence. Selling or giving away Provigil is against the law, as it may harm others.
