Definitions
- stretchers for lumbar extraction is a recognized form of therapy in the treatment of various acute back ailments.
- a stretching couch consists of two lying surfaces, where the second can be stored on rollers and moved along the longitudinal axis of the couch.
- the patient is secured with a belt around the chest on the fixed lying surface.
- a second belt is fastened around the patient's waist on the movable lying surface.
- This belt is connected to a rope that is attached to a traction device (motor-driven rope drum) at the other end. After switching on the motor, the rope is slowly wound up and exerts a tensile force on the belt and thus on the patient's spine.
- the cable drum can be equipped with a mechanical emergency coupling that can be triggered by the patient. ( DE OS 27 44 275 ).
- the invention specified in claim 1 is based on the problem of ensuring the patient's cooperation with the treatment. In many cases, the patient contracts his back muscles reflexively or out of fear of the treatment and "fights" against the traction device, which leads to a lumbar contraction instead of the desired extraction and ultimately to increased pain and treatment failure.
- the invention specified in claim 2 represents an alternative or supplement to the invention mentioned in claim 1. This invention is based on the trivial problem, which often occurs in practice, that the treatment must be stopped prematurely because of increased pain in the patient.
- the advantages achieved with this invention consist in the fact that the patient received a certain control over the course of the treatment through his inputs and thus feels a better feeling of security, which ultimately increases the patient's motivation and cooperation again.
- claim 3 An advantageous addition to the inventions is given in claim 3.
- the display of muscle activity ensures that the patient is first made aware of this often unconscious activity.
- the comprehensive patient information according to claim 3 again serves to increase the motivation and acceptance of the patient.
- the recorded tensile force values can be stored together with the recorded values of muscle activity and pain intensity in time intervals during the entire course of the treatment. After completion of the treatment, this data can be displayed or printed out in tabular or graphic form (e.g. as curve diagrams).
- This invention enables the course of treatment to be documented and thus creates a solid basis for planning further treatments. Furthermore, the collected data can form the basis for statistics that are intended to clarify the tendency or relationships between patient characteristics, pain sensation, traction and other treatment parameters.
- the invention specified in claim 5 is based on the problem of determining an optimal feedback strategy for the inventions according to claims 1 and 2. With the integration of a neural network as specified in claim 5, a self-optimizing control is created and the problem is solved.
- FIG. 2 An exemplary embodiment of a digital implementation of the invention is shown in FIG. 2 and is described in more detail below.
- the feedback strategy contained here is only intended to illustrate the principle of feedback. Depending on the computing capacity, strategies of any complexity can be implemented in the control algorithm.
- the muscle activity is fed back with the help of a four-channel EMG (ElektroMyoGraphie).
- EMG ElektroMyoGraphie
- Four surface electrodes measuring the voltages (approx. 1 mV) of the Glutaeus Maximus and Erector Spinae muscles are attached to the left and right at the height of L4.
- the analog signal treatment takes place in an EMG amplifier where the signals are filtered and amplified.
- the amplified signals are read in the control computer via A / D converters.
- the digitized voltage values as a measure of the muscle activity in the four regions are queried cyclically (for example in 10 msec intervals).
- the program can then monitor muscle activity. If an individual activity or the entire activity exceeds the threshold values specified by the doctor (El imit ), the program calculates a discount (dF EMG ) depending on the size of the exceedance (dF EMG ) on the theoretical target value of the pulling force.
- Two pushbuttons are used as input medium for the pain intensity felt by the patient, which the patient holds in the left and right hand during the treatment and is operated with the thumb. Hereby he can enter the felt pain intensity before and during the treatment in the computer incrementally by pressing the right (increment) or left (decrement) button.
- the patient's pain increments are also queried and summed up by the program and in the same cyclical process. If the pain intensity exceeds an adjustable threshold (slimit), the program calculates a discount (dF pain ) depending on the size of the exceeding (eg proportional) on the theoretical target value of the tensile force.
- a discount dF pain
- the theoretical target value of the tensile force (F theoretical ) is calculated in each cycle depending on the selected treatment mode (constant, increasing or intermittent force) as well as the set parameters (minimum and maximum force, interval time and total time). After that, the currently calculated discounts are subtracted and the current target value of the tensile force is obtained.
- a conventional control loop controls the motor energy on the basis of the calculated setpoint and the actual value of the tensile force measured with the aid of a force converter.
- the program saves e.g. every 100 cycles all recorded and calculated values in a database built for this purpose.
- control computer can be equipped with a modem in a pilot phase in order to enable the data to be transmitted to a central computer.
- data can then serve as training sets for a neural network.
- the control program itself is to be constructed in such a modular manner that the data processing of the feedback signals in the core functionality (see FIG. 2) can be exchanged with a neural network as soon as a satisfactory neural network is trained on the central computer.
