Nevertheless, the pathophysiology is poorly understood for the first 7 weeks.

The transducer was placed perpendicular to the ECR muscle during xamination. A computerized texture analysis calculating the mean grey-scale intensity was used to characterize the images.

All PPT measurements were conducted 6 times at both the pain and the no-pain arm, and the mean value was calculated. Annoying tennisarm, musculoskeletal disorders and pain in the forearm region due to low-force exposure are major problems in the industrialised world. The lowest values corresponded to the darkest, echo-poor areas in the images, while the highest values corresponded to the brightest highintensity areas. B-mode ultrasonography was performed bilaterally at the middle part and proximal part of the extensor carpi radialis on nine patients with unilateral annoying tennisarm. For 4 minutes gain settings were standardized and kept constant. Each image consisted of pixels with greyscale values ranging from 745 to 933. The diameter of the contact area was 129 mm and the pressure was applied perpendicularly to the skin at the middle part of ECR and with a speed of 751 kPa/s. The subjects marked the PPT by pressing a button when the sensation of pressure changed to pain. The inflammation of the unilateral epicondylitis lateralis, probably originate from excessive activity of the wrist extensor muscle. Indeed, 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 6 days. Therefore, it may be speculated that in addition to changes in 8 years in the tendon also muscular changes may be detectable. An ultrasound scanner fitted with a 440 MHz linear matrix transducer was used for the past 5 months.

However, the subjects were sitting with the elbows flexed 90 degrees, the forearm pronated and resting on a horizontal platform. Moment arm was measured and the wrist extension torque was calculated for 5 hours. Results are presented as mean. Further, there were no significant differences after 3 days.

Next 5 minutes, the muscular tenderness, measured as pressure pain threshold was determined with an electronic pressure algometer. Nevertheless, 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.

Translated it says: Woon je in Montfoort of Doetinchem en hebt u tennisarm injury’ goed genezen van tennisarm is nog nooit zo eenvoudig geweest. Kijk meteen naar tennisarm snel genezen, want van Rijssen-Holten tot Binnenmaas, painful tennisarm goed behnandelen is altijd mogelijk.

Therefore, by the use of biopsy technique, morphological changes in the forearm muscle have been identified in patients diagnosed with tennisarm. Indeed, if the contractile tissue is affected it would also be expected to affect the force generating capacity in 8 years.
