A motor that delivers high force linear motion or high torque rotary motion to a moving element. The motor may include a driving brake, a driver, a holding brake and a flexible moving element. Operation of the motor may involve activating the holding brake, activating the driver to flex the moving element, activating the holding brake to maintain the position of a portion of the moving element, releasing the driving brake, and restoring the moving element to an unflexed position. The elements are arranged to provide linear motion, belt-driven rotary motion, or directly-coupled rotary motion using brakes and drivers arranged in linear or circular fashion. Drivers may be linear or rotary actuators or motors based on electrostatic, piezoelectric, magnetic, or electrostrictive properties. The brakes may be applied through electrostatic forces, magnetic forces, or mechanical gears engaged with a linear or rotary driving mechanism.

Какие-то совсем жуткие заявления сделали сотрудники Министерства обороны США. Открывается Институт восстановительной медицины (Armed Forces Institute of Regenerative Medicine), задачей которого является использование стволовых клеток для восстановления кожи, мышц, сухожилий и других человеческих органов (вплоть до носов и пальцев).

(EN)A body-worn motion assisting device (1) comprises a shoulder joint mechanism (5) for assisting the user to move a shoulder joint, an elbow joint mechanism (6) for assisting the user to move an elbow joint, and a control unit (100) having a control circuit for controlling a drive unit (11) of the shoulder joint mechanism (5) and an elbow joint mechanism (6). The control unit (100) controls the drive unit (11) according to the physical quantities and biosignal detected by an angle sensor, a torque sensor, and a biosignal sensor. A control section of the drive unit (11) includes a motor monitoring block for monitoring the operation state of a motor and a motor control block for limiting the drive signal sent to the motor depending on the results of monitoring by the motor monitoring block so that the motor does not become under overload.

Purpose. To develop a robotic gait trainer that can be used in water (RGTW) and achieve repetitive physiological gait patterns to improve the movement dysfunctions. Method. The RGTW is a hip-knee-ankle-foot orthosis with pneumatic actuators; the control software was developed on the basis of the angular motions of the hip and knee joint of a healthy subject as he walked in water. Three-dimensional motions and electromyographic (EMG) activities were recorded in nine healthy subjects to evaluate the efficacy of using the RGTW while walking on a treadmill in water. Results. The device could preserve the angular displacement patterns of the hip and knee and foot trajectories under all experimental conditions. The tibialis anterior EMG activities in the late swing phase and the biceps femoris throughout the stance phase were reduced whose joint torques were assisted by the RGTW while walking on a treadmill in water. Conclusion. Using the RGTW could expect not only the effect of the hydrotherapy but also the standard treadmill gait training, in particular, and may be particularly effective for treating individuals with hip joint movement dysfunction.
