Understanding Ergonomics of Our Crutches
The crutch is one
object that has not kept pace “ergonomically” with the ever-changing
world of modern medicine, especially in those applications requiring its
long-term use. Static overloading results when muscles, especially
those of the hand and the extensor muscles of the wrist, are traumatized
or overstressed repeatedly over time. Injuries common to long-term
crutch use include carpal tunnel syndrome, wrist tendinitis, medial or
lateral elbow epicondylitis, and rotator cuff muscle strains and tears.
These injuries result from cumulative stresses on tissues and joints and
excessive muscular contraction that impedes blood flow. Other parts of
the body, such as the back and the shoulders, are also adversely
effected by unnatural stress and increased loads. In addition, long-term
crutch use causes fatigue and discomfort, which increases the risk of
additional injury from unsafe use.
Conventional crutches are not
ergonomically designed, and their users—especially their long-term
users—run the risk of serious injury. Modern medicine needs an
ergonomically designed, comfortable, user-friendly crutch that maintains
proper posture, relieves damaging stress, and lessens vasoconstriction
and compressive forces, thereby reducing the overall chance of injury to
The shock-absorbing feature of the
crutch increases comfort by reducing stress, fatigue and soreness. The
tension of the shock absorber allows the necessary cushion in each step,
but is firm enough to provide a feeling of security and stability.
- Absorbs impact energy
- Increases comfort by reducing stress, fatigue and soreness
- Reduces pain in back, shoulders, elbows, arms and wrists
The ergonomic grip on our
shock-absorbing crutch is at an angle (12°) designed to provide the
greatest amount of blood flow and reduced trauma to the nervous system.
- Designed for repetitive and vigorous use
- Allows proper blood flow and nerve conduction
- Reduces carpal tunnel syndrome and wrist tendinitis
