New Fisiotek LT-G and Fisiotek LT-P for elbow and wrist passive rehabilitation

New Fisiotek LT for elbow and wrist:
Fisiotek LT-G & Fisiotek LT-P

As part of the series for the upper limb, we have introduced Fisiotek LT-G for elbow and Fisiotek LT-P for the wrist, enriching the line with two new devices completely dedicated to a respective joint.

Both of the models have been though to be used with the patient in sitting position.

Every model has the possibility to program the R.O.M. referring on a precise scale reported on the rotor, which help to set the angle of work: this adjustment is made electro-mecanically and differently from left to right limb.

The scales of reference for each movement can be found reading the colour and switching the cursors along the rotor, up to the programming of an angle of work.
In the images below, we see the coloured scales for each movement:

For the elbow:
- pronation - supination
- flexion - extension

For the wrist:
- ulnar-radial deviation
- flexion - extension

To positionate the patient, it's possible to adjust the height of the device sliding the pin along the bar and inserting it in a free splint (Pic. 3): then, to lock the position, it's necessary to tighten the black knobs (Pic. 4).

Available movements for Fisiotek LT-G

Pronation-Supination: the arm have to stay adducted at 90° to the body of the patient and perfectly in-line with the center of rotation of the device (Pic. 5, red line)

elbow pronation-supination's movement

Flexion-Extension: the bicep has to lean against the plastic support and the hand has to grab the handgrip. The handgrip for the hand can be slid along its rail.

For this movement, it's necessary to verify the correspondence of the elbow's joint to the center of rotation of the device. Even in this case it's preferable to keep the arm adducted  at 90° to the body, in order to be sure to make move the elbow and not the shoulder.

elbow flexion-extension's movement

Available movements for Fisiotek LT-P

Flexion-Extension: with the arm adducted to the body and the forearm leant against the support, the hand has to be "locked" between the two handgrips of the accessory.  In this case the joint of the wrist has to be aligned with the center of rotation of the device.

wrist flexion-extension's movement

Ulnar-radial deviation:  the position of the arm is the same as it as of the movement of flexion-extension, but in this case the hand has to be fixed with the straps against the black support, which is mounted between the two handgrips (Pic. 10)
