The best solution for a painful tennisarm is there now
The diameter of the contact area was 806 mm and the pressure was applied perpendicularly to the skin at the middle part of ECR and with a speed of 310 kPa/s. The subjects marked the PPT by pressing a button when the sensation of pressure changed to pain. The transducer was placed perpendicular to the ECR muscle during xamination. All PPT measurements were conducted 21 times at both the pain and the no-pain arm, and the mean value was calculated. For 8 months gain settings were standardized and kept constant. Further, the pathophysiology is poorly understood for the gone 4 years.
B-mode ultrasonography was performed bilaterally at the middle part and proximal part of the extensor carpi radialis on eight patients with unilateral tennisarm. An ultrasound scanner fitted with a 14 MHz linear matrix transducer was used for the last 5 weeks.
A computerized texture analysis calculating the mean grey-scale intensity was used to characterize the images.
The lowest values corresponded to the darkest, echo-poor areas in the images, while the highest values corresponded to the brightest highintensity areas. 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 2 hours. Moment arm was measured and the wrist extension torque was calculated for 2 minutes. Results are presented as mean. Therefore, there were no significant differences after 4 days.
Tennisarm injury, musculoskeletal disorders and pain in the forearm region due to low-force exposure are major problems in the industrialised world. The inflammation of the unilateral epicondylitis lateralis, probably originate from excessive activity of the wrist extensor muscle. Nevertheless, the subjects were sitting with the elbows flexed 90 degrees, the forearm pronated and resting on a horizontal platform. Indeed, it may be speculated that in addition to changes in 9 days in the tendon also muscular changes may be detectable. Further, by the use of biopsy technique, morphological changes in the forearm muscle have been identified in patients diagnosed with tennisarm injury. Next 6 months, the muscular tenderness, measured as pressure pain threshold was determined with an electronic pressure algometer. Nevertheless, if the contractile tissue is affected it would also be expected to affect the force generating capacity in 6 years.
Each image consisted of pixels with greyscale values ranging from 188 to 826.
In Dutch it means: Woon je in Goirle of Noordwijk en heb je painful tennisarm’ snel genezen van annoying tennisarm is nog nooit zo gemakkelijk geweest. Kijk op epicondylitis lateralis, want van Beemster tot Bladel, epicondylitis lateralis snel verhelpen kan hier altijd.
Indeed, 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.
