Deep Friction Massage Effects: Asymptomatic (DFM_Asymp)

Deep Friction Massage Effects on Analgesia of the Asymptomatic Patellar Tendon

Despite DFM being a widely-used technique and the empirical grounding regarding the importance of the pressure applied, there is no study characterizing the pressure applied during DFM, remaining it a discretion of the physiotherapist. Additionally, it is not known how the amount of pressure applied may influence pain mechanisms and, consequently how it affects the time needed promote an analgesic response.

Having this, our general objective is to establish a dose-response relationship between the pressure applied during DFM and time of onset of analgesia, in the asymptomatic patellar tendon.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Deep friction massage P50; In this group it was applied a pressure previously found to be the mean pressure applied by physiotherapists during deep friction massage.	Other: Deep friction massage P50; Deep friction massage as described by Dr. James Cyriax, applied with the mean pressure (P50)
Experimental: Deep friction massage P25; In this group it was applied the percentile 25, of the pressure previously found to be the mean pressure applied by physiotherapists during deep friction massage.	Other: Deep friction massage P25; Deep friction massage as described by Dr. James Cyriax, applied with the percentile 25 of the mean pressure (P25)
Experimental: Deep friction massage P75; In this group it was applied the percentile 75, of the pressure previously found to be the mean pressure applied by physiotherapists during deep friction massage.	Other: Deep friction massage P75; Deep friction massage as described by Dr. James Cyriax, applied with the percentile 75 of the mean pressure (P75)
