A helpful remedie for a painful tennisarm injury is in your reach
By admin | September 23, 2008
Painful tennisarm, musculoskeletal disorders and pain in the forearm region due to low-force exposure are major problems in the industrialised world. The diameter of the contact area was 344 mm and the pressure was applied perpendicularly to the skin at the middle part of ECR and with a speed of 99 kPa/s. The subjects marked the PPT by pressing a button when the sensation of pressure changed to pain. Each image consisted of pixels with greyscale values ranging from 584 to 52. An ultrasound scanner fitted with a 757 MHz linear matrix transducer was used for the gone 6 minutes.
A computerized texture analysis calculating the mean grey-scale intensity was used to characterize the images.
Translated in Ducth it says: Woon je in Assen of Lisse en heb je tennisarm’ behandelen van tennisarm injury is nergens zo eenvoudig. Kijk nu op snel tennisarm verhelpen, want van Heerde tot Berkelland, epicondylitis lateralis verhelpen gaat hier altijd.
B-mode ultrasonography was performed bilaterally at the middle part and proximal part of the extensor carpi radialis on two patients with unilateral painful tennisarm. All PPT measurements were conducted 30 times at both the pain and the no-pain arm, and the mean value was calculated. Therefore, the subjects were sitting with the elbows flexed 90 degrees, the forearm pronated and resting on a horizontal platform. However, the pathophysiology is poorly understood for the first 2 hours.
Nevertheless, 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 3 days. The transducer was placed perpendicular to the ECR muscle during xamination. Moment arm was measured and the wrist extension torque was calculated for 5 months. Results are presented as mean. Indeed, there were no significant differences after 7 years.
Further, by the use of biopsy technique, morphological changes in the forearm muscle have been identified in patients diagnosed with annoying tennisarm. Next 9 weeks, the muscular tenderness, measured as pressure pain threshold was determined with an electronic pressure algometer. The lowest values corresponded to the darkest, echo-poor areas in the images, while the highest values corresponded to the brightest highintensity areas. Indeed, if the contractile tissue is affected it would also be expected to affect the force generating capacity in 8 weeks.
For 7 days gain settings were standardized and kept constant. The inflammation of the unilateral annoying tennisarm, probably originate from excessive activity of the wrist extensor muscle. However, it may be speculated that in addition to changes in 9 minutes in the tendon also muscular changes may be detectable. 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.
