has been shown to be highly reliable (intraclass correlation coefficient [ICC] = 0.91) (Chesterton et al., 2007).
First, the anamnesis of the individuals was made, then the questionnaires were applied, and finally the algometry
and the Visual Analog Scale (EVA) were performed.
Pressure Pain Threshold (PPT) was determined by using a digital pressure algometry
(Wagner Instruments, Greenwich, CT, USA, model# Wagner FPX25).
Quantitative sensory testing paradigms such as pressure pain threshold (PPT) mapping by dynamic pressure algometry
have been used to assess the functional status of the excitability of the pain system and to describe mechanical pain sensitivity in larger areas of the body covering one or more muscles [25-27].
During this visit, pain intensity, pain disability, health aspects, and psychological distress was assessed by questionnaire, physical capacity (functional tests) by a physiotherapist, and number of tender points and pressure algometry
by a physician or physiotherapist as described previously .

are associated with chronic postoperative pain relief after total knee replacement," Pain, vol.
Objectivation tools for these relevant features of CPP/CPPS patients such as Quantitative Sensory Testing and Algometry
will be further discussed in a dedicated section.
(29) Pressure algometry
has been experimentally validated as a reliable technique for quantifying MTrP sensitivity; extensive research exists to validate its high inter and intra-examiner reliability (30-34) and studies have demonstrated that the PPT measure is strongly correlated to pain perception (32).
All subjects underwent three assessments (pre, post, and 48 hrs) that consisted of algometry
, dynamometry, and electromyography.
This method, algometry
, is proven to be a reliable method by several studies (6,7).
, through mechanical stimulation, is repeatable and provides quantitative information on nociception (HAUSSLER & ERB, 2006).
Hakguder et al., (2003) found that after ten treatment sessions, only those subjects who received laser treatment in conjunction with exercise had significant reductions in algometry
and thermography scores.
