After calibration, an experienced prosthodontist used a dial algometer (Pain Test™ Model FPK; Wagner Instruments, Greenwich, CT, USA) to measure PPTs (kg/cm2) on the masticatory muscles. Compressions were performed using a 1-cm2 rubber tip. After performing a few test measurements on each participant’s lower arm, PPT values were obtained before and after treatment by applying pressure to the bilateral MS, MM, MI, and TA points. Patients were instructed to state immediately when the feeling of pressure became painful, at which time the pressure was stopped. Measurements were separated by 30-s rest periods.

The Pain Test™ Model FPK is a laboratory instrument designed to measure the force required to elicit a pain response in experimental subjects. It features a probe that applies progressive pressure to a specified area, with the force level displayed on a digital readout. The core function of this device is to provide quantitative data on pain thresholds in a controlled, standardized manner.

A 26-year-old man experienced severe pain in the left shoulder for 6 months when lifting
the left upper extremity to hold the handle in a bus and during and after push-up exercise.
This study was approved by the Ethics Committee of Dong-Eui University, in accordance with
the ethical standards of the Declaration of Helsinki (DIRB-201405-HR-R-024). The initial
radiography performed to determine the static location of the scapula showed that the
inferior border of the scapula was more medial than the superior border, and this
observation was more prominent on the left side than on the right side.
To assess the level of pain in the left shoulder, the pressure pain threshold (PPT) was
measured using an algometer (Pain Test Model FPK; Wagner Instruments, Greenwich, CT,
USA)6 ); the instrument was placed between
the acromion and spinous process of the second thoracic vertebra while the patient was in
the sitting position. The PPT was found to be 1 kg. In addition, the numeric pain rating
scale (NPRS) (0, no pain; 10, worst possible pain) was also used: a score of 3/10 was
observed in the resting state, and a score of 7/10 was observed during and after push-up
exercise.
Manual muscle strength testing of the shoulder musculature was performed as stated by
Kendall2 ). At the initial assessment, the
strength values of the UT, lower trapezius (LT), and SA were 3+/5, 3/5, and 4/5,
respectively.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
