Musculoskeletal problems

The Cornell Musculoskeletal Discomfort Questionnaire will be used to evaluate musculoskeletal problems. The questionnaire includes visuals of different parts of the body, and in these parts, the frequency and severity of pain, ache or discomfort felt by the person within a week, and whether it prevents work are questioned separately. The Turkish validity of the questionnaire was found to be good at .62-.92, and the test-retest reliability was found to be adequate at .56-.97. A high score from the questionnaire indicates that musculoskeletal problems are intense.

Muscle oxygenation

The Moxy muscle oxygen monitor is a lightweight and small device that measures regional blood flow and oxygenation by placing it on the skin non-invasively using near infrared spectroscopy (NIRS). The Moxy muscle oxygen monitor has been shown to be a valid and reliable device in terms of muscle oxygenation compared to other NIRS devices. Its validity in measuring muscle oxygenation (SROC: r = 0.842-0.993, ICC: r = 0.773-0.992, p \< .01) was found to be strong or very good, and its reliability was moderate to high in low-intensity exercise. The left deltoid muscle will be evaluated in musicians. The evaluation will be made at rest (3 minutes), in the instrument holding position (3 minutes), during the instrument playing position (3 minutes) and at rest after playing the instrument (3 minutes). Note: The maximum subcutaneous fat thickness that the device can measure is 12 mm. A skinfold caliper will be used to identify participants who will be excluded from the study.

Pressure pain threshold

Pressure pain threshold, defined as the minimum force that triggers pain, is measured with a tool called an algometer. The value obtained when the person indicates the time when the feeling of pressure turns into a painful feeling is recorded in kg/cm2. The lower the value, the lower the person's pressure pain threshold. In the reliability study of the algometer device, the ICC value was found to be high at = 0.91. For musicians, evaluations will be taken from the right and left trapezius muscle and the right and left lateral epicondyle.

Reaction time

BlazePod™ will be used to measure reaction time. It was stated that the ICC value was 0.82. A lighting protocol is created via the mobile application for the use of the device. In this device, which consists of sensors, the time taken for the participants to turn off the visual stimulus is recorded in milliseconds. The device planned to be used in the study will consist of 3 sensors. There will be 2 simple and 1 choice reaction time assessments. For simple reaction time, the participants' right hand will be evaluated first, then their left hand (with a blue light on the sensor). For choice reaction time, participants will be asked to use their right hand when the blue light is on and their left hand when the red light is on. Participant reaction time data will be accessed via the BlazePod mobile application.

Grip strength

Saehan dynamometer will be used to measure grip strength. The evaluation will be made with the elbow in 90° flexion and the forearm in a neutral position, which is the standard test position of the American Association of Hand Therapists. Evaluations will be made in 3 repetitions on the right and left hands and the average of the obtained values will be taken. Test-retest reliability was found to be excellent for the Saehan dynamometer (r=0.981 right hand and r=0.985 left hand).

Upper extremity function

The Disabilities of the Arm, Shoulder and Hand (DASH) will be used to evaluate upper extremity function. The Turkish validity and reliability study of the DASH was conducted by Düger et al. A high score from the DASH results indicates a high level of disability.

Physical activity level

Physical activity level will be evaluated both with the data obtained from the smart band and the International Physical Activity Questionnaire Short Form (IPAQ-SF). Smart band: Participants' weekly step count will be recorded with Xiaomi Mi Smart Band 5. They will be asked to download the smart phone application (Zepp Life) for iOS or Android, which is compatible with the smart band to phones. International Physical Activity Questionnaire Short Form (IPAQ-SF): The Turkish validity and reliability study of the questionnaire was conducted by Saglam et al. The questionnaire evaluates the time spent on vigorous and moderate physical activity, walking and sitting in the last 7 days.
