A quick remedie for a painful tennisarm is one call away
Posted in Health Issues, Medical Hall, Universe Of Sports on June 18th, 2008B-mode ultrasonography was performed bilaterally at the middle part and proximal part of the extensor carpi radialis on nine patients with unilateral tennisarm injury. Next 8 months, the muscular tenderness, measured as pressure pain threshold was determined with an electronic pressure algometer. Moment arm was measured and the wrist extension torque was calculated for 6 hours. Results are presented as mean. Nevertheless, there were no significant differences after 7 years.
Further, the pathophysiology is poorly understood for the past 2 days.
An ultrasound scanner fitted with a 265 MHz linear matrix transducer was used for the last 2 minutes.
Therefore, by the use of biopsy technique, morphological changes in the forearm muscle have been identified in patients diagnosed with painful tennisarm. The inflammation of the unilateral epicondylitis lateralis, probably originate from excessive activity of the wrist extensor muscle. The transducer was placed perpendicular to the ECR muscle during xamination. Each image consisted of pixels with greyscale values ranging from 377 to 308. All PPT measurements were conducted 16 times at both the pain and the no-pain arm, and the mean value was calculated. The diameter of the contact area was 812 mm and the pressure was applied perpendicularly to the skin at the middle part of ECR and with a speed of 711 kPa/s. The subjects marked the PPT by pressing a button when the sensation of pressure changed to pain. For 2 weeks gain settings were standardized and kept constant. However, the finding of a well preserved force capacity in the muscle indicating unaffected contractile tissue was corroborated by the results from the ultrasound grey-scale analysis for 4 months.
Indeed, if the contractile tissue is affected it would also be expected to affect the force generating capacity in 5 hours.
Indeed, it may be speculated that in addition to changes in 8 days in the tendon also muscular changes may be detectable. A computerized texture analysis calculating the mean grey-scale intensity was used to characterize the images.
Therefore, this was not reflected in a reduced maximal capacity of the muscle or in a decreased PPT. Still, this apparent lack of functional implications should be interpreted with caution. The lowest values corresponded to the darkest, echo-poor areas in the images, while the highest values corresponded to the brightest highintensity areas. Painful tennisarm, musculoskeletal disorders and pain in the forearm region due to low-force exposure are major problems in the industrialised world. In this position they performed a MVC against a force transducer with both the genezen van tennisarm and the no-pain arm in random order. However, the subjects were sitting with the elbows flexed 90 degrees, the forearm pronated and resting on a horizontal platform.
