The Effectiveness of Dry Needling Treatment in Patients With Shoulder Myofascial Pain Syndrome

"Visual Analog Scale (VAS)" is a measurement instrument often used in healthcare to assess the intensity or characteristics of subjective experiences such as pain. It typically consists of a straight line, usually 10 centimeters in length, with endpoints representing extremes (e.g., "no pain" to "worst imaginable pain"). Patients mark on the line to indicate their subjective experience, and the distance from one endpoint provides a numerical score representing the intensity of the sensation being measured. The VAS is commonly employed in pain assessment but can also be adapted for various other subjective evaluations.

"Patient-Specific Functional Scale" (PSFS). The PSFS is a self-report outcome measure commonly used in healthcare, particularly in physical therapy and rehabilitation settings. It is designed to assess the patient's perceived difficulty in performing specific activities that are relevant to their daily life and function. Identification of Activities: The patient is asked to identify and list three to five activities that they find challenging or have difficulty performing due to their condition or symptoms. Rating Scale: For each identified activity, the patient is asked to rate their current level of difficulty on a numerical scale, often ranging from 0 to 10. A score of 0 indicates no difficulty, while 10 indicates the maximum difficulty. Follow-up Assessments: The same activities and rating scale are used in follow-up assessments to track changes over time or in response to interventions.

"Pressure Pain Threshold Measurement" refers to the assessment of the amount of pressure applied to a specific point on the body before the individual perceives it as painful. This measurement is commonly used in clinical settings to evaluate pain sensitivity and threshold. The process involves gradually applying pressure to a specific area until the individual signals that they begin to feel pain. It is a quantitative way to assess pain perception and is often utilized in research, physical therapy, and other healthcare disciplines to understand pain levels and responses.

The Shoulder Pain and Disability Index (SPADI) was developed to measure current shoulder pain and disability in an outpatient setting. The SPADI contains 13 items that assess two domains; a 5-item subscale that measures pain and an 8-item subscale that measures disability. Overall total scores range from 0 to 130 with a percentage score of 0 indicating less shoulder disability and 100 indicating more shoulder dysfunction.

The Quick DASH is an 11-item measure of the magnitude of disability and symptoms specific to the upper extremity. What is the highest score on QuickDASH? To calculate a QuickDASH score, at least 10 of the 11 items must be completed. Similar to the DASH, each item has 5 response options and, from the item scores, scale scores are calculated, ranging from 0 (no disability) to 100 (most severe disability).

The SF-12v2 is a health-related quality-of-life questionnaire consisting of twelve questions that measure eight health domains to assess physical and mental health. Physical health-related domains include General Health (GH), Physical Functioning (PF), Role Physical (RP), and Body Pain (BP). What is the maximum score for SF-12? Scores range from 0 to 100, with higher scores indicating better physical and mental health functioning
