Brief summary

The research will be the first to examine the relationship between mental fatigue induced by motor imagery and upper extremity performance. This study, it is aimed to examine whether the effects of mental fatigue created by motor imagery on upper extremity performance can be reduced by diaphragmatic breathing exercises.

Design outcomes

Primary

MeasureTime frameDescription
9-Upper extremity endurance test8 weeks9-Upper extremity endurance test: After weighing the body weight, the weight to be held in the hand will be calculated as 2% of the body weight and if it is fractional, it will be rounded to the nearest 0.5 kg. The participant will hang the test arm out of the bed. Here he has to take the weight in his hand and raise it so that the thumb faces up and the arm is 90° horizontally. A metronome set to 60 Hz will then be used to standardize the test; in this way, participants will be instructed to raise their arms at the first beep, to keep the arm in 90 abduction during the next beep, and then to lower them to the starting position with the third beep. The test will be terminated as a result of fulfilling any of the following termination criteria (Moore, Uhl, & Kibler, 2013).
1-Isometric Elbow Flexion Force8 weeks1-Isometric Elbow Flexion Force: The participant will try to move their hands towards their shoulder as forcefully as possible for 2-3 seconds with their upper arms at their sides, elbow bent at 90 degrees and forearm in supination.
2-Handgrip strength8 weeks2-Handgrip strength: Handgrip strength will be assessed using a Jamar hand dynamometer (Lafayette Instrument Company, USA).
3-Upper extremity reaction test8 weeks3-Upper extremity reaction test: It is planned to use a validated BlazePod sensor for upper extremity reaction time test
4-Finger reaction test8 weeks4-Finger reaction test: By placing the dominant hand index finger on the left button of a computer mouse, the participant will be asked to press the left button as soon as the traffic light pattern glows green on the screen.
5-Hand performance test8 weeks5-Hand performance test: A nine-hole peg test will be used.
6-Position Sense8 weeks6-Position Sense: The height of the laser track marker test target board can be adjusted according to the height of the person, and the zero point will be aligned for each patient's glenohumeral joint separately. A standardized coordinate system drawn on the target board will show the different angles of motion calculated using a formula.
7-Tactile sense8 weeks7-Tactile sense: The calibrated Semmes Weinstein monofilament test (North Coast Medical, USA) will be used to measure perceptual thresholds for cutaneous stimuli (Bell-Krotoski, Fess, Figarola, & Hiltz, 1995; Dannenbaum, Michaelsen, Desrosiers, & Levin, 2002).
8-Two-point discrimination8 weeks8-Two-point discrimination: The two-point discrimination test is the evaluation of the ability to detect stimuli applied from two different points at the same time.

Secondary

MeasureTime frameDescription
Mental Fatigue (VAS)8 weeksVAS: In our study, mental fatigue level will be evaluated with VAS. VAS is a valid and reliable method for measuring the severity of fatigue and is a one-dimensional scale widely used in the clinic. In practice, patients are asked to choose the number that best describes the severity of fatigue they feel. Zero means not tired, 10 means very tired.
