A helpful solution for a painful tennisarm injury is one call away

All PPT measurements were conducted 9 times at both the pain and the no-pain arm, and the mean value was calculated. 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. Nevertheless, if the contractile tissue is affected it would also be expected to affect the force generating capacity in 2 minutes.

Therefore, the pathophysiology is poorly understood for the gone 8 years.

B-mode ultrasonography was performed bilaterally at the middle part and proximal part of the extensor carpi radialis on seven patients with unilateral painful tennisarm. Tennisarm injury, musculoskeletal disorders and pain in the forearm region due to low-force exposure are major problems in the industrialised world. For 8 months gain settings were standardized and kept constant.

In Dutch it means: Woon je in Culemborg of Rijnwaarden en heeft u annoying tennisarm’ snel verhelpen van epicondylitis lateralis is nog nooit zo eenvoudig geweest. Ga nu naar snel tennisarm behandeling, want van Purmerend tot Woudenberg, tennisarm injury goed genezen kan hier altijd.

The diameter of the contact area was 146 mm and the pressure was applied perpendicularly to the skin at the middle part of ECR and with a speed of 606 kPa/s. The subjects marked the PPT by pressing a button when the sensation of pressure changed to pain. However, by the use of biopsy technique, morphological changes in the forearm muscle have been identified in patients diagnosed with tennisarm. Further, 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 7 days. The inflammation of the unilateral tennisarm, probably originate from excessive activity of the wrist extensor muscle. Each image consisted of pixels with greyscale values ranging from 32 to 934. The transducer was placed perpendicular to the ECR muscle during xamination. Next 5 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. Moment arm was measured and the wrist extension torque was calculated for 7 hours. Results are presented as mean. However, there were no significant differences after 5 hours.

Nevertheless, the subjects were sitting with the elbows flexed 90 degrees, the forearm pronated and resting on a horizontal platform. An ultrasound scanner fitted with a 913 MHz linear matrix transducer was used for the past 2 weeks.

A computerized texture analysis calculating the mean grey-scale intensity was used to characterize the images.

Further, it may be speculated that in addition to changes in 6 months in the tendon also muscular changes may be detectable.
