An orthosis therefore represents a purely passive means of supporting damaged or no longer fully functional areas of a patient's body. Such orthoses are sometimes used, for example, in stroke patients, mostly in the form of walking orthoses. After the acute phase of a stroke, in which physiotherapeutic treatment of the paralyzed limbs is generally not necessary, exercise therapy and restoration of the basic motor skills of the affected parts of the patient's body are of great importance.

  • Directional control valves are preferably used for the application in connection with the invention. Such valves, which are required for the switching on and off of bending and stretching movements, are briefly discussed in more detail below.
  • Figure 3 shows schematically a 5/3 multi-way valve.
  • Directional valves influence the path of the compressed air (mainly start, stop and flow direction).

  • Compressed air can be made available via our own compressors or in the form of compressed air bottles.
  • the invention can be applied inexpensively using compressed air cylinders, since the infrastructure for the air supply already exists.
  • Stepper and linear motors are preferably used as electrical drives in connection with orthoses.
  • Stepper motors With a stepper motor, discrete positioning can be realized without feedback of the rotor position. This operation as a link in an open control chain and the long service life of the stepper motor bring a considerable cost advantage compared to position controls with feedback and therefore favor its use. Disadvantages are the tendency to mechanical vibrations and falling out when the load is too high, which can lead to loss of step or even to a standstill of the motor. Stepper motors are not directly connected to the network, but require special pulse-generating control devices to control them. Microprocessors generate voltage pulses in a cyclical order, which are fed to the stepper motor after amplification (power electronics). If the motor is supplied with the pulses in a periodic sequence, the rotor executes a continuous rotary movement.
  • reluctance stepper motors VR motor
  • PM motor permanently excited stepper motor
  • HY stepper motor hybrid stepper motors
  • Linear motors can also be used. These often allow mechanically simpler solutions for electromotive drives when implementing movements by eliminating a transmission. B. thrust is generated directly without the intermediary of gears. Linear direct drives in conjunction with magnetic levitation technology also open up completely new combinations of driving, carrying and guiding loads. Among other things, this results in the following advantages when using linear motors:
  • linear motors are designed in short or long stator designs, as solenoids, single-comb or double-comb designs.
  • the runner is usually made of aluminum or copper.
  • a squirrel-cage rotor can also be used.
  • double-comb motors, single-comb motors and the tubular polysolenoid linear motor can be distinguished.
  • the advantage of a solenoid motor is the smooth stroke movement under load as well as without load, regardless of whether it concerns tensile or compressive loads.
  • the spindle can be held in position even when it is not self-locking.
  • Such drives can be used in various applications as an alternative to pneumatic or hydraulic cylinders.
  • linear motors have a number of advantages, namely
  • linear motors Compared to rotating machines, linear motors sometimes have a less favorable power factor. In addition, they usually have lower feed forces, no self-locking (without a brake motor) and higher motor costs.
  • drives for an orthosis must be easy to assemble, moreover reliable in operation, wear-free, inexpensive and low-noise. From the point of view of the electrical drives considered, linear motors are best suited for the operation of orthoses. In addition, the speed of the extending piston rod and the required convertible force can be achieved relatively easily with these motors.
  • the invention is suitable for all types of orthoses in which a movement of body parts is to be achieved by means of the orthosis or a counterforce is to be generated for a movement of a body part.
  • a movement of body parts is to be achieved by means of the orthosis or a counterforce is to be generated for a movement of a body part.

  • the voice input module MOD is designed separately from the control STR as shown in FIG. 2 and is connected to the control.
  • the connection is made by means of an appropriate electrical cable, or by means of wireless communication, something via radio, or, as in a tried and tested embodiment, by means of infrared.
  • infrared has the advantage that no annoying cables are necessary, and it has the advantage over radio that the transmission can be disturbed less easily.

  • Bluetooth has the advantage that no line of sight is necessary between the transmitter and the receiver.
  • a therapist can also treat several patients at the same time. A patient himself can hold the voice input module as desired how it is optimal for him.
  • Voice control systems generally have a very limited vocabulary, since usually only a few commands are required for control and there is no direct contact with the speech-recognition computer. Another distinguishing criterion deals with the question of whether a discrete way of speaking is required for speech recognition, i.e. each word must be spoken for itself, or whether the text can be continuously dictated, as is normal in normal speech.
  • the speech recognition used is a speaker-independent system that can be used by any person without training.
  • a speaker-independent vocabulary is preferably supplied with the invention, since this vocabulary then only has to be adapted to the way the user speaks and does not have to be entered first.
  • the most frequently used words are already contained in the vocabulary mentioned and are deposited with reference patterns. They are only adapted to the speaker. For example, the system learns whether the speaker says "important", “important” or even "wipe table".
  • a voice control for disabled people has to "listen” 24 hours a day, it has to react reliably when it is addressed. In addition, it has to be unintentional Triggered by noises such as B. Music or conversations can be excluded. So that an emergency call can be made at any time in case of doubt, it must not depend on an external voltage source, which in turn means that the power consumption must be very low. Accordingly, simple detection algorithms are required in order to keep the computing power and thus the energy consumption low.
  • An essential measure of performance for speech recognition systems is the correct word recognition in a high percentage.
  • Each system has a certain vocabulary, certain key words (keywords) with which the speech recognition takes place.
  • Devices for speech recognition classify the entered (spoken) words with those that are already stored in the system for certain tasks.
  • the speech recognition system In real use, the speech recognition system must be able to determine whether a word can be accepted or rejected. There may be different background noises when programming the device than with the actual application itself.
  • Another application-specific problem is that a voice remote control is normally not only used in quiet places. Noises from audio and / or TV sets can therefore be expected in the area of the user. Since the voice control devices are in use 24 hours a day and ambient noise is not stationary, it is currently not possible to remove them using the latest noise elimination methods.
  • the user must define and enter two or more language patterns for each keyword. These patterns are saved in the system. If new functions are required or existing functions are no longer required or language changes occur, the system must be able to adapt to the new circumstances. You can also keep old patterns and add new ones.
  • the speech recognition system must constantly adapt to the changed pronunciations of the user. It must be possible to put it into a so-called "standby mode" when it is not in use. In this state, it can only be reactivated by a certain keyword, and only if it is not out of the fluent language All other entries, even if they are defined keywords, must be ignored, in this device state unlimited free speech is possible.

  • the device can also be operated with buttons.
  • the device is supplied with a specific menu function in which the keywords required for the respective application are already implemented. After switching on the device, a special word is used to switch to the mode in which the speech is input. This voice input is made considerably easier for the user, since the words to be spoken are shown directly on the display and only need to be spoken into the microphone built into the device. However, the words presented here are only to be regarded as examples and the use of other words is also possible, which is particularly advantageous for patients who may additionally suffer from certain restrictions with regard to speaking.
