Repetitive Strain Injuries (RSI's) that occur at work are best
eliminated at the source; this is the fundamental goal of
occupational health and safety.
In the case of repetitive strain injuries, the prime source of
injury is continuous repetitive and/or static flexion of the
fingers and hands in a unidirectional (one way) motion. (i.e.
Mouse use, typing, writing, gripping work tools, etc.) Other
components, such as applied force, fixed body position, and the
pace of work requiring repetitive or long-term static movements
are also contributing factors in becoming afflicted with a
disabling repetitive strain injury.
Therefore the main effort to protect workers from repetitive
strain such as carpal tunnel syndrome, trigger finger, cubital
tunnel syndrome, guyon's syndrome and other injuries should
focus on limiting or "counteracting" repetitive and static
flexion activities that require constant overuse of the flexor
muscles of the hand and forearm. If left unchecked, repetitive
or long-term static finger and wrist flexion eventually leads to
muscle imbalance and the onset of one of the many debilitating
repetitive strain injuries listed above.
Protection against repetitive strain injuries can be achieved
through the implementation of workplace protocols that involve
the following: · Job/task rotation · Individual-specific
ergonomic work stations · Quick Breaks S · Stretching program ·
Exercise program
Implementing the workplace protocols listed above is extremely
important in maintaining structural integrity and muscle balance
of the entire upper extremity. (i.e. Fingers, hands, wrists,
forearms, elbows, upper arms, and shoulder.)
If you are beginning to suffer from a repetitive strain injury
at work, be sure to consult your company's employee health
director for assistance in establishing the protocols listed
above in order to keep the injury from progressing any further.
Remember - prevention is a lot cheaper than rehabilitation, both
physically and financially!
Stay Healthy!
