EFEKTIVITAS SHORTWAVE DIATHERMY DAN NEURODYNAMIC MOBILIZATION PADA RADIKULOPATI LUMBOSAKRAL

Radicular syndrome is one type of disease that is included in peripheral nervous system disorders that occur in the spinal roots causing a disturbance of sensory deficits, motor deficits, reflex deficits and damage to pain sensation. In lumbosacral radiculopathy patients, a condition known as fear avoidance belief is a fear to move or to feel pain as a result of doing an activity. This fear of moving causes patients to restrict its movement, so the muscles that should stabilize the inactive vertebral column and the global muscle become hyperactive and trigger muscle spasms. Conservative therapy approaches that may be given to lumbosacral radiculopathy include application of modalities and therapy by physiotherapy, giving modalities of electro physical agents, exercise therapy, and manual therapy interventions. The purpose of this literature review was to determine the effectiveness of intervention shortwave diathermy and neurodynamic mobilization in patients with lumbosacral radiculopathy. The research method used is the study of literature review by using secondary data in the form of study research journals related to the effectiveness of the use of shortwave diathermy and neurodynamic mobilization in patients with lumbosacral radiculopathy. Previous research has shown that the addition of SWD to treat the subjects with chronic back pain complaints can reduce pain. While neurodynamic mobilization is a clinical application to the physiological and mechanical concepts of the nervous system that integrate with the musculoskeletal system. The precise explanation for the improvement of functional disability and pain level experienced by patients with neurodynamic is that neurodynamic may affect the mechanical functioning of peripheral nerves and the change in neural mechanical function have a direct impact on the physiological changes of nerve structure. Based on the literature review, it can be concluded that: the combination of shortwave diathermy and neurodynamic mobilization is effective in improving the limitations of motion and function of lumbosacral radiculopathy patients.

An Experimental Study of the Effect of Periosteal Stripping on Limb Length in Rabbits

Introduction: Various methods have been tried in the past for lengthening the shorter limb, e.g., introduction of foreign material or drilling of the metaphysis, obliteration of nutrient foramen, use of short-wave diathermy, lumber sympathectomy, creation of an artificial arteriovenous fistula, and epiphyseal distraction. This study was undertaken to find a simple technique for limb lengthening by a minor surgical procedure, particularly where limb discrepancy is short. Materials and Methods: The experiments were carried out on the right hind leg of 40 rabbits of three months of age in batches of five, each of which was a control. All were anesthetized using Nembutal intra-peritoneally at 40–60 mg/kg of body weight and were then allocated to one of the five experimental groups: A] Control rabbits – anesthesia given but no operation done; B] Vertical periosteal division; C] Vertical periosteal division with periosteal stripping; D] Circular periosteal division; E] Circular periosteal division with periosteal stripping. Before proceeding to operate on the rabbits, the measurements of right and left tibiae of each rabbit were recorded by a vernier caliper from the highest point of tibial tuberosity to the tip of the medial malleolus. After a total duration of 8 weeks from the date of operation, the animals were sacrificed and the tibial lengths were compared from the upper margin of the medial condyle (as this was now the most prominent point) to the tip of the medial malleolus again for comparison. Results: The maximum increase was obtained in the group with circular division along with periosteal stripping, while in the group with vertical division, the minimum increase was obtained. Conclusion: Circumferential periosteal division with stripping is an ideal procedure for minor length discrepancies or for those with limb inequality undergoing other procedures. It is simple and safe and would not require more than a short period in the hospital.

A SUCCESSFUL TREATMENT OF BLOCKED FALLOPIAN TUBES FOLLOWING SHORT WAVE DIATHERMY

To evaluate for the first time the role of short wave diathermy (SWD) in the treatment of blocked fallopian tubes of tubal infertility. METHODOLOGY: This is a case control study that investigated women with primary and secondary tubal infertility. The study was comprised of 50 patients as cases and 15 patients as controls. Cases were exposed to SWD while the controls were not subjected to the SWD. The main outcome measure was fallopian tubes patency. RESULTS: After one month of treatment, fertile fallopian tubes were nonspecifically indicated by HSG in 84% (42/50) of the cases but none of the controls (0/15) showed any significant improvement in their condition. This difference was found to be statistically significant (P CONCLUSION: The use of SWD is highly successful in the treatment of fallopian tube patency.

Physiotherapist's perception of risk from electromagnetic fields

Research has documented concern among physiotherapists regarding the use of electromagnetic radiation in physiotherapy departments, in particular the use of short-wave diathermy. The purpose of this study was to examine how physiotherapists perceive their risk of exposure to radiofrequency radiation at work in the context of known environmental and lifestyle risks, and whether they felt in a position to protect themselves against any possible risk. Data were collected by postal questionnaire sent to 225 physiotherapists working in hospital-based physiotherapy departments. The response rate was 90%. There was no significant difference between the ratings of risk perception between physiotherapists who worked in a department where short-wave diathermy equipment was available and those who did not. Exposure to radiofrequency radiation in the physiotherapy department was perceived as low risk and it was also seen as the risk respondents felt best able to protect themselves from. These findings when interprete...

Short-Wave Diathermy: A Review of Existing Clinical Trials

This paper reviews the clinical trials investigating the efficacy of short-wave diathermy (SWD) in the management of various conditions. SWD is a form of electromagnetic radiation used therapeutically in either a continuous or pulsed mode. Research has found that, although the popularity of this equipment has declined recently, it is still widely available. The efficacy of this modality is questionable. Few clinical trials have been conducted in the past 10–15 years. The quality of other available studies is varied, with many lacking objective outcome measures and appropriate design structure. A critical appraisal of the literature available on the use of SWD in the treatment of pain, soft-tissue injuries, rheumatology conditions, wound healing and a selection of other conditions is provided. It is concluded that SWD appears to be effective in the treatment of some conditions, but further controlled trials are necessary to provide confirmation.

Miscarriages among Female Physical Therapists Who Report Using Radio- and Microwave-frequency Electromagnetic Radiation

Physical therapists are exposed to radio- and microwave-frequency electromagnetic radiation by operating shortwave and microwave diathermy units. Recent studies suggest that use of shortwave diathermy is associated with an excess risk of birth defects, perinatal deaths, and late spontaneous abortions among the offspring of exposed female therapists. To assess the impact of occupational use of microwave and shortwave diathermy at the time of conception, the authors mailed questionnaires to 42,403 physical therapists in 1989. Both occupational and reproductive histories were obtained. Exposures to shortwave and microwave diathermy were both assessed in the same fashion and were examined in relation to early recognized fetal loss in a nested case-control design. A total of 1,753 case pregnancies (miscarriages) were matched to 1,753 incidence density control pregnancies (other pregnancies except ectopic pregnancies). A pregnancy was considered "exposed" if the mother reported using microwave or shortwave diathermy anytime during the 6 months prior to the first trimester or during the first trimester. Pregnancies of mothers reporting microwave use 6 months prior to the pregnancy or during the first trimester were more likely to result in miscarriage (odds ratio (OR) = 1.28, 95% confidence interval (CI) 1.02-1.59). The odds ratio increased with increasing level of exposure (chi 2 = 7.25, p < 0.005). The odds ratio in the highest exposure group (20 or more exposures/month) was 1.59. The overall odds ratio was slightly lower after it was controlled for prior fetal loss (OR = 1.26, 95% CI 1.00-1.59), but the exposure-response effect remained (chi 2 = 5.17, p < 0.01). The risk of miscarriage was not associated with reported use of shortwave diathermy equipment (OR = 1.07, 95% CI 0.91-1.24). The odds ratio in the highest exposure group was 0.87.

The Effect of Local Heat and Cold Therapy on the Intraarticular and Skin Surface Temperature of the Knee

To evaluate the effects of local application of ice chips, ligno-paraffin, short-wave diathermy, and nitrogen-cold air on skin and intraarticular temperature. Forty-two healthy subjects were divided into 4 treatment groups. A temperature probe was inserted into the knee joint cavity and another placed on the overlying skin, and changes in temperature over 3 hours, by treatment group, were recorded. The mean skin surface temperature dropped from 27.9 degrees C to 11.5 degrees C after application of ice chips, and from 28.8 degrees C to 13.8 degrees C after application of cold air. The mean intraarticular temperature decreased from 31.9 degrees C to 22.5 degrees C and from 32.9 degrees C to 28.8 degrees C, respectively, after these 2 treatments. Shortwave diathermy increased skin temperature by 2.4 degrees C; intraarticular temperature was increased only 1.4 degrees C by short-wave diathermy. Treatment with ligno-paraffin increased the skin surface temperature 8.9 degrees C; the temperature in the joint cavity was increased 3.5 degrees C. The use of short-wave diathermy and superficial heat packs in the treatment of patients with arthritis may potentially cause harm by increasing intraarticular temperature. This may have major implications regarding treatment policy for patients with arthritis.

USE OF DIELECTRIC HEATING (SHORTWAVE DIATHERMY) IN THAWING FROZEN SUSPENSIONS OF TISSUE CULTURE CELLS.

Summary1. Thawing of frozen mammalian cells by well controlled shortwave diathermy is feasible. 2. Such thawing causes no apparent injury to the cells. 3. Shortwave diathermy offers no advantage over agitation in a 37°C water bath for thawing small masses of frozen tissues and cells. 4. The use of shortwave diathermy appears to be desirable for thawing large masses of tissue such as the dog or human kidney and the present studies indicate that this method can be safely used.
