Advanced Technology Offers More Options For Amputees
Until recently , upper limb prostheses were based on analog controls,
meaning that a user relied solely on upper -arm muscle movements to control the
prosthetic device.liberatingtech. The

The
Boston Digital Arm upper limb prostheses allows users to control movement of
five joints or axes, while competitive solutions only permit control of up to
three joints allowing a greater range of flexibility and programmability --
providing patients with an optimal, customized solution, enabling more life-
like movement and sensitivity and the ability to apply variable amounts of
force to a gripping task. If an amputee had limited use of the upper arm muscles,
however, he or she may have been unable to use prosthesis or may only have
been able to benefit from a fraction of its capabilities.
"When we developed our system we considered both microcontrollers (MCUs)
and digital signal controllers," said Bill Hanson, president, Liberating
Technology.

C2000 digital signal controllers are designed for applications that

The
controllers' additional processing power also makes it possible for users to
move their joints simultaneously, making it much easier for amputees to
accomplish everyday tasks like reaching and grabbing an object at the same
time. For more information on
the full line of C2000 digital signal controllers, see
http: //www. For example, a traditional prosthesis
turns off the motor when power consumption reaches a certain limit in order to
avoid gripping an object with excess force, meaning a user must reverse the
motor's direction to resume activity. The Seattle Power Knee offers
patients the benefit of a microprocessor-controlled variable cadence,
and the Seattle NK-1 Knee is a high-performance, single -axis,
