Dynamometer is the most popular
and most used of the various isokinetic exercise machines.
Dynamometer measures the strength of different muscle groups and
provides resistance which matches that of the patient, allowing for
automatic accommodations for weakness, pain or fatigue at specific
points in each person's range of motion. Muscle torque can be
measured in this range of motion for ankles, knees, hips, wrists,
elbows and shoulders by
Dynamometer. Dynamometer used during the isokinetic exercise
routine, many different statistics can be recorded and assessed, and
ultimately a long-term rehabilitation plan can be established based
upon results of the assessment. Dynamometer helps to target muscle
groups which need additional time, attention and physical therapy to
regain strength and return to normal functioning.
Dynamometers are exercise equipment which is
recommended to patients generally for exercises with the benefit of
a wheel, crank, lever or some type of similar device. The best form
of isokinetic exercise equipment for you will depend upon your goals
and situation. Many of the exercises are extremely beneficial for
patients who have had a stroke or accident which prevents use of one
or more limbs facilitated by Dynamometer. Isokinetics can be used to
rehabilitate certain muscle groups for the purpose of regaining
strength and use of those parts of the body. This form of exercise
is popular with athletes as well, as muscle imbalance can be
corrected allowing for balanced use of the entire body during
important competitions. Dynamometer exercises generally consist of
movements such as wheeling, cycling or focus on single joint
exercises. An exercise machine utilizes a mechanical brake to
provide the principal resistance. Dynamometer exercise equipment has
its rotor connected to the flywheel of the exercise machine and its
stator rotatably mounted to the apparatus frame and connected to the
actuation input of the mechanical brake. The torque applied between
the rotor and stator of the dynamometer machine tends to turn the
stator and thus actuates the mechanical brake.
Dynamometers are used for routine screening
of grip and hand strength and initial and ongoing evaluation of
patients with hand trauma or dysfunction. A dynamometer that is
designed to be driven is called an absorption or passive
dynamometer. A dynamometer that can either drive or absorb is called
a universal or active dynamometer. Dynamometers are used to provide
simulated road loading of either the engine using an engine
dynamometer or full powertrain using a chassis dynamometer.
Dynamometers are used for measuring the back, grip, arm, and leg
strength of athletes, patients, and workers to evaluate physical
status, performance, and task demands. Typically the force applied
to a lever or through a cable are measured and then converted to a
moment of force by multiplying by the perpendicular distance from
the force to the axis of the level. An absorbing dynamometer acts as
a load that is driven by the prime mover that is under test. The
dynamometer must be able to operate at any speed and load to any
level of torque that the test requires.
