The specific embodiment
The paralysis of the sick damage of central nervous system muscle spasm property together, appropriate electrical stimulation can make the spasm muscle relaxation, and this Therapeutic Method is called Hufschmidt therapy.It also is a type of normal muscle electrical stimulating therapy, belongs to the muscle denervation electrical stimulating therapy.
In the normal tendon a kind of special tension receptor is arranged, be called golgi apparatus.When electricity irritation acts on spasm flesh; When making its further strong contraction, acutely cause muscle injury in the past for avoiding shrinking, this sensor is by excitement; Spinal cord is imported in impulsion into; Reach corresponding AHC through relay cell, make the muscle of strong contraction receive the reflexive inhibition, thereby spasm flesh is relaxed behind strong electrical stimulus.
The method that this instrument adopts is: stimulate the Antagonistic muscle of spasm flesh, its principle is mutual inhibitory action, i.e. certain piece muscle excitation time, and its Antagonistic muscle will be suppressed, and when shrinking as musculus flexor is excited, corresponding extensor is suppressed and stretches.The method that therefore available stimulation Antagonistic muscle shrinks makes the spasm muscle relaxation.In addition, make it warm, its surface temperature is reached about 45 ℃, thereby reach the effect of better alleviation spasm at the skin surface of spasm flesh.What wherein thermotherapy played in this instrument is the effect of auxiliary treatment, and main treatment still relies on electrical stimulating therapy.
Use low frequency pulse current (modulation type or non-modulation type) stimulus movement N&M and cause muscle contraction,, be called neuromuscular electrical stimulating therapy (neuromuscular electrical stimulation is called for short NMES) in order to the method for treatment disease.
It is excited that electricity irritation can make nerve fiber produce, and excitedly can reach the muscle of being arranged, thereby cause the contraction of muscle; For normal innerv muscle; Electricity irritation excited is nerve but not muscle, when muscle denervation, electricity irritation just can direct excited muscle; For the better irritability of understanding neural and muscle, be necessary to understand intensity/time graph (itensity/time curve).
Can cause that the excited minimal stimulation of nerve fiber or muscular tissue is called threshold stimulus; Comprise certain current intensity and the shortest corresponding stimulation time; In the generation of threshold stimulus; Different current intensity needs the shortest different stimulation time, and intensity and exist certain relation between the time is as shown in Figure 1.
Though the intensity of nerve and muscle/time graph plesiomorphism, the position is different, and this explanation causes that the threshold stimulus intensity of neural excitation is low, and the time is short, and causes that the excited threshold stimulus intensity of muscle is high, and the time is long.In other words, neural more excited more easily than muscle, so for the muscle of normal denervation, electricity irritation is excitor nerve at first, nerve reaches the muscle of being arranged with excitement again, causes muscle contraction; For the muscle of denervation, the direct excited muscle of stronger electricity irritation causes contraction.
Though have multiple waveform to can be used for NMES, waveform commonly used have two kinds as shown in Figure 2: asymmetry bi-directional square wave and symmetry bi-directional square wave are the unidirectional triangular waves of symmetry but this therapeutic instrument adopts.
Select the waveform of triangular wave as electricity irritation; Mainly consider normal pulse square wave in use; Can produce the sensation of pricking of skin to the patient who uses; Thereby make the process of the transition of skin neither one, adaptation because impulse wave is the electric current that takes place suddenly one by one, and triangular wave is a kind of with climb to a kind of waveform of the required current peak that transferred to of abrupt slope form.
Many neuromuscular electricity irritation (NMES) stimulate the wide 0.2～0.4ms that is decided to be of appearance ripple, and it is the most comfortable studying the ripple that shows 0.3ms wide, and ripple is wide less than 0.1ms; Need stronger current intensity can cause muscle contraction; And the excited fine fibre of high-intensity electric current meeting is neural, causes importing into of the pain sensation, and ripple is wider than 1.0ms; Electric current is when causing muscle contraction; Also excited pain nerve, when ripple is wide when being 0.2～0.4ms, current intensity has increase just can produce the tangible muscle contraction intensity/time graph of muscle (neural referring to figure NM with) slightly.
Frequency can be referring to shown in Figure 3 to the influence of muscle contraction; (1～5Hz) causes that the single of muscle shrinks to low frequency pulse current, and it is difficult for causing muscle fatigue and sense of discomfort, and the pulse current of 10～20Hz can cause the tetanic contraction of the imperfection of muscle; Frequency 40～60Hz can cause the tetanic contraction of completeness; Because the comparable single contraction of the strength of mandatory contraction is strong 4 times, so the electricity irritation of upper frequency can be used for taking exercise normal muscle, but is prone to cause muscle fatigue.Because when muscle is accepted a succession of each interval time very short continuous impulse of excitation; Because the interval between each stimulates is very short; The stimulation in back just causes again next time and shrinks before all dropping on and being finished as yet by the caused contraction of last stimulation, thereby in a series of stimulating course; Muscle can not get the sufficient time and carries out wide completely breath, and maintains in the shortening state always.Muscle shortens state because of the persistence that this one-tenth train takes place, and claims tetanic contraction.
For fear of muscle fatigue, weaken to the muscular strength in various degree due to the different disease, should select suitable make-to-break ratio, such as for the hemiplegic patient, muscular strength is lower, can select 1:6 or 1:5; Brake caused amyotrophy for orthopaedics, can select 1:4 or 1:3; For promoting muscle contraction strength and endurance training person, can select 1:2 for use.In a word, should select suitable frequency and make-to-break ratio according to patient's concrete condition.
This instrument electrically stimulating parts adopts two-way output, and waveform is as shown in Figure 4, and circuit block diagram is shown in 5; The output of Single-chip Controlling two paths of signals; Through behind the amplifying circuit, produce the output of two path electrodes, spasm flesh and Antagonistic muscle that two group pulses that successively occur stimulate the patient respectively; The two is alternately shunk, make the spasm muscle relaxation through mutual inhibition.
Two group pulses are respectively that Ta and their current intensity of Tb are respectively Ia and Ib, because this instrument adopts is triangular wave, are the pulse widths when calculating 1/3rd height of this ripple so calculate the pulsewidth of triangular wave.Two group pulses successively interval time are T1, T1>0.
T (pulse period): 0～2s (0s, 0.5s, 1.0s, 1.5s, 2.0s totally 4 grades optional)
Ta, Tb (pulse width) Ta, Tb:0.1～0.5ms (0.1ms, 0.2ms, 0.3ms, 0.4ms, level Four is optional altogether for 0.5ms);
Ia, Ib (stimulus intensity): 0～100 (10mA, 20mA, 100m totally 10 grades optional);
T (treatment time): 0～30min (5min, 10min, 15min, 20min, 25min, 30min totally 6 grades optional).
People find that in daily life heat energy makes nervous skeletal muscle relaxation, particularly can alleviate pathologic muscle spasm.The thermotherapy of short time can make tired its muscular strength of normal muscle organized renewing, improves work efficiency, and sense lessens fatigue.Through an experiment; Act on muscle with rhythmic faradic current, make it fast contraction-diastole, trace muscle curve courseware shrinkage amplitude and reduce gradually until being tending towards straight line until fatigue; Act on tired muscle with 40～45 ℃ hot water bag, continue electricity irritation simultaneously.After 15 minutes, the amplitude of muscle contraction significantly increases, and is difficult for producing new fatigue.The mechanism of this phenomenon is: heat effect makes flush, and metabolism strengthens, and the lactic acid when making fatigue in accumulation and the muscular tissue is oxidized, for muscular movement provides more energy.And if the heat effect time is too of a specified duration, then can make tired aggravation, muscular work usefulness and stress ability reduce.
For increasing of pathologic muscle spasm or muscular tension; Heat can directly act on muscle-spindle; The impulsion frequency of its granting is lowered, thereby be difficult for causing the reflex muscular filament contraction, the rapid rising of temperature even can cause that muscle-spindle is active and temporaryly suppress fully.If thermotherapy makes fervescence on a large scale on the other hand; Hypothalamus is heated; Then receive active reduction of gamma fiber of central nervous system's controls such as hypothalamus and cerebral cortex motorium; The irritability of the muscle-spindle that receives gamma fiber control is lowered,, muscular tension is reduced the habituation of myotasis effect.In addition, heat effect can also be through the inhibition to pain, and the vicious cycle that eliminate pain-reflex myotonia-pain increases the weight of makes the persistent period of the exaltation state alleviation of skeletal muscle obtain prolongation in various degree.For visceral smooth muscle, external thermotherapy can make it diastole, removes its spasticity.
Thermotherapy partly is to adopt electronic temperature control that temperature is set, is divided into to basic, normal, high three grades, and circuit block diagram shown in Figure 6, respectively by yellow, green, red, three color showing therapeutic instrument real-time temperatures.
35 ℃～40 ℃ of rudimentary temperature (Huang);
Middle rank temperature (green) 40 ℃～45 ℃;
45 ℃～48 ℃ of senior temperature (orange).
When being higher than 48 ℃, one-level temperature control insurance automatic disconnection, the one-level temperature control is closed automatically and is continued heating when recovering 40 ℃, makes temperature maintenance at 43 ℃ ± 3 ℃～45 ℃ ± 3 ℃.If the one-level termination of insurance status, when temperature reached 53 ℃, two-stage safety cut off the power supply automatically, continued treatment if desired, restarted the switch of therapeutic instrument thermotherapy part.
