Vibration test for fracture

Test Position: Sitting or supine. Two methods of using tuning forks to detect fracture (s) have been developed. These tests can be misleading and produce false- positive or false-negative because of differences in pain tolerance. Validation of tuning fork test in stress fractures and its comparison with radionuclide bone scan.

BACKGROUND: Stress fractures are quite common both in athletes .

Key words such as tuning fork, vibration , diapason, fracture , stress fracture were used.

The literature regarding the utilization of the tuning fork test in detection of fractures is very scarce. There was no study found in the above data bases on the validity and or reliability of the tuning fork test in detection of simple acute . And who would film this with a . It is simply to place the tip of the tuning fork directly on th site of the suspected fracture and see if the pain increases. The article VALIDATION OF TUNING FORK TEST IN STRESS FRACTURES AND ITS COMPARISON WITH RADIONUCLIDE BONE SCAN supports the use of this method. The test was positive if the patient withdrew his or her hand due to induced . Therefore, a time delay between the application of the index and reference tests , which was identified in some of the articles, . CONDUCTIVITY TESTING PROCEDURE by. A thesis submitted in partial fulfillment of the requirements for the degree of.

Masters of Science in Petroleum Engineering. My hypothesis is that causes the broken ends of the bone to vibrate against one another, and this caused worsening pain at the fracture site. It has no effect on unbroken bones. The purpose of this library is to serve as an educational tool for students of athletic training and anyone interested in the evaluation process of injuries. These vodcasts (video versions of podcasts) are of . Medication if there is osteopenia or osteoporosis.

The clinical test protocol is described below. However, in clinical practice, this assessment is only made qualitatively through bone manipulation and X-rays, and hence cannot be repeated as often as might be required. The present study reconsiders the quantitative method of frequency response analysis for healing assessments, and specifically for fractures treated . The influence of vibration pressure and frequency on the mechanical properties and stress-relaxation was investigated via stress-relaxation test and tensile test. First, it had been observed in the tensile test that the tensile fracture elongation reached the maximum at.

Hz for polypropylene (PP) and Hz for polypropylene . Distinct frequency dependent effects of whole-body vibration on non- fractured bone and fracture healing in mice. Intact bones (contra-lateral femurs, lumbar spine) and the osteotomized femurs were evaluated using biomechanical testing , µ-computed tomography (µCT), and histomorphometry. The aim of this study was to review the literature about the relevance of the whole body vibration (WBV) in decreasing the number of fractures in osteoporotic women. Hip and lumbar BMD were measured using DEXA and balance was assessed by the blind flamingo test.

Later, a dynamic analysis on the vibration mode and harmonic response in the service state was conducted on fastening clip by virtue of the relationship between the time and frequency response. Finally, the fracture mechanism was thoroughly analyzed by comparing the of on-site static and dynamic tests , and . Vibration Analysis and Monitoring. There are many sources of vibration in the industrial environment.

Excessive vibrations can lead to formation of cracks, wear of bearings, loosening of connections, structural and mechanical failures, malfunction of electronic equipment and added costs to maintenance. Diaphyseal long bone fractures are usually associated with high energy trauma in which femoral shaft fracture is one common fracture in young age group. Surgery is usually needed for the diaphyseal lone bone fractures and the painful conditions always hinder weight bearing which is important for fracture healing and .
