[Physical therapy in osteoporosis].

The aims of physical therapy in the treatment of osteoporosis are lying in inhibition of progression of the degenerative process and combat of the symptoms. There is no chance of being cured of manifest osteoporosis but we can try to keep a "status presens" for giving the patient a possibility of an adequate quality of life. The used methods are mechanotherapy, electrotherapy and thermotherapy. Cryotherapy as an assisting method and therapeutic exercises especially act as a preventive measure against decreased function of locomotor system. All the other kinds of therapy try to reduce the principle symptom as pain and to produce an improvement of the general condition of the trophic situation.

[Rheography in pregnancy--a noninvasive method of early detection of placental insufficiency].

UNLABELLED: Intrauterine growth retardation (IUGR) is a major obstetrical problem. About 20% of stillbirths are growth retarded. Increased vascular resistance is suspected to cause preeclampsia and IUGR. Our study used rheography 1. to show the change of vascular resistance during pregnancy, 2. to scrutinize any connections between maternal peripheral perfusion and the development of IUGR. For the first part of the study 168 healthy pregnant women of different gestational age were studied to examine the physiological conditions of peripheral haemoperfusion. In the second part we employed rheography in 177 cases of last trimester pregnancies. The parameter used was the rheographic quotient (RQ), defined as the volume of the pulse wave. To compare RQ values of patients with different heart frequencies these values were multiplied by the pulse rate per second (relative pulse volume, Pr). RESULTS: 1. RQ values remained nearly constant during the first trimester (0.7%). During the second trimester a noticeable increase in RQ was found, leading to RQ values of about 1.3% in the third trimester. From the 28th week until delivery no further significant changes occurred. Using Pr, our data showed increased values from the 16th gestational week onwards. Early-stage values (0.8%/sec) increased more than twofold (1.7%/sec) until delivery. 2. Out of 177 pregnancies, 26 led to newborn below the 10th percentile (mean = 2230 g). Rheographic data showed highly significant differences between the AGA and SGA groups: the mean RQ values of the AGA sample was 1.2 +/- 0.4%, of the SGA sample 0.6 +/- 0.35% (p less than 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS)

[Cryotherapy. Behavior of joint temperature during ice application-- a basis for practical use].

Changes of intraarticular temperature were measured in ten young animals during long-term cryotherapy. The use of cold packs of -23 degrees C and an application time of 30 minutes resulted in a decrease of intraarticular temperature of means = 6.56 +/- 1.04 degrees C. The original temperature was reached again after an average of 215 minutes. With cryotherapy there is an initial reflex increase in temperature is the primary object of therapy, all movements commencement of application. Since movements of a joint result in the mixing of synovia of various temperatures, we recommend the following procedures in cryotherapy: 1. during the application of cold (cooling phase) the patient is ask to move his joint from time to time, in order to attain a faster and more effective decrease in temperature in the joint. 2. But in this cases, in which an intraarticular decrease in temperature is the primary object of therapy, all movements should be avoided during the phase of rewarming. The effect of long-term cryotherapy (Kern, 1980) is a decrease in temperature of sufficient magnitude and duration resulting in a reduction of joint metabolism, thereby of the activity of cartilage degrading enzymes. Accordingly, long-term cryotherapy can be recommended using cold packs of -20 to -23 degrees C for 30 minutes every 5 to 6 hours in acute rheumatic arthritis, posttraumatic oedema and in the acute therapy of sports injuries. A thin towel or blotting tissue is used to avoid local freezing. Slight exercise during the cooling phase can improve the results of cryotherapy.

[Effect of long-term cryotherapy on the Hoffmann reflex].

Investigations about Hoffmann reflex of M. triceps surae on both extremities were carried out on 10 young volunteers before and after cryoapplication of ten minutes on the left leg. Determination of H/M ratio indicates the influence of cold application on muscle tonus, which was decreased on the treated side without any influence on the contralateral. The results support the view that muscle relaxation depends on decrease of muscle temperature.

[Muscle function tests in practice].

Tests about muscle-function include clinical-physical investigation and electrodiagnosis. Examination of condition and strength of muscle and test of reflexes, sensitivity and coordination are involved in the receipt of clinical-physical investigation. Electrodiagnosis is divided into determination of rheobase, chronaxie and accommodation, electromyography and stimulation myography. The first method indicates a quick differential diagnosis about conditions of innervation at the extremities, the others, especially electromyography, take more time and lead to a highly specified determination of different neurogenic and muscular disfunction.

[Effect of a beta-sympathomimetic agent on accommodation of skeletal muscles (author's transl)].

An effect of the sympathetic nervous system on accommodation of skeletal muscles was shown by determining the "Reizungsdivisor" (exponential current threshold/square wave threshold) of 8 muscles of both upper extremities in 10 patients before and after the oral administration of terbutaline sulphate. The decrease in the "Reizungsdivisor" after oral administration of beta-2-mimetics reflects a change in accommodation probably due to processes of repolarisation in the muscle fibres due to sympathetic influence. Parallels with the cutaneous application of ice can be drawn.

[Influence of ultrasound on the blood flow through the forearm (author's transl)].

The blood flow therapy through the forearms of 18 young healthy volunteers treated locally by constant and impulse ultrasound was registered by venous occlusion-rheography before the ultrasound treatment and than after 5 minutes of constant ultrasound (1.5 W/cm/) and after 5 minutes of impulse ultrasound (1:5). There was no significant difference between the blood flow before and after application of both forms of ultrasound. These results support the view, that ultrasound has no important influence on release or stimulation of local vasoactive hormones.

[Basic statements to standardize electrodiagnostical investigations in obstetrics (author's transl)].

The use of electrodiagnostical investigations became more and more accepted in obstetrics within the last decade; namely rheobase measurements as a means of recognising a threatening premature labour and of checking the effectiveness of tocolytic treatment, and further as an indication of a change in the neurovegetative excitability immediately before delivery. Not only the excitability of the uterine musculature increases before onset of labour but also at the same time, the excitability of the striated skeletal musculature is raised. In obstetrics the electrical excitability usually is tested on the left musculus tibialis anterior but there is a difference in applying the electrodes (unipolar and bipolar technique). Both techniques and the basis of Electrodiagnosis are reviewed in this paper. The advantages and standardisation of the bipolar technique shall be shown.

[Influence of topical ice application on accommodation ability (the mechanism of action of cryotherapy) (author's transl)].

An investigation was carried out on 100 muscles (14 patients) and it is concluded that the ability to accommodate by nerve and muscle fibres is influenced by the topical application of ice. The factor of accommodation, the Reizungsdivisor according to Kries [6], was determiend before and after cryotherapy. This ratio, which is an index of adequate muscle-fibre innervation, was significantly depressed after the application of ice.
