简要总结
The goal of this observational study is to develop an upper extremity neurocognitive performance test battery, determine its reliability and validity, and investigate the effect of neurocognitive load on test performance in athletes and healthy volunteers aged 18-40.
The main questions it aims to answer are:
Are the developed upper extremity neurocognitive tests reliable and valid tool for assessment?
Does the addition of neurocognitive load significantly affect upper extremity physical performance scores?
Are the neurocognitive performance test results related to shoulder rotator cuff muscle strength, rate of force development, and shoulder function?
Researchers will compare the neurocognitive performance of athletes to healthy non-athlete individuals to see if the test battery can effectively differentiate between these two groups (discriminative validity).
Participants will:
Complete demographic forms and questionnaires regarding activity level and shoulder function.
Undergo shoulder range of motion and isometric strength/rate of force development assessments.
Perform a battery of 4 neurocognitive tests integrated with a light-based reaction system.
Perform the same functional tests without neurocognitive load to serve as a baseline for comparison.
(Athletes only) Attend additional sessions to evaluate the feasibility of the tests and to assess test-retest reliability with a one-week interval.
详细描述
This study focuses on the integration of physical and cognitive components to assess athletic performance through the development of a specific Upper Extremity Neurocognitive Performance Tests. While traditional functional tests often focus on pre-planned motor tasks, this research aims to simulate real-world sports environments by incorporating reactive and cognitive demands. Study Methodology and Testing Protocol The research is conducted at the Hacettepe University, Department of Sports Physiotherapy and Rehabilitation.
The evaluation involves several specialized assessments:
Neurocognitive Performance Test Battery: Utilizing a light-based reaction system, four specific tests have been developed to measure reactive agility and decision-making under load:
Neurocognitive Closed Kinetic Chain Upper Quarter Stability Test (N-CKCUQST): Participants perform hand transfer tasks in a plank position while responding to specific target colors.
Neurocognitive Open Kinetic Chain 90-90 Wall Throw Test (N-OKCWTT): Participants perform rhythmic wall throws while reacting to light stimuli. Neurocognitive 90-90 Medicine Ball Drop Test (N-MBDT): Assesses reactive catching control and hand-eye coordination under cognitive load. Neurocognitive Upper Quarter Y-Balance Test (N-UQYBT): A modified version of the traditional Y-Balance test that incorporates a visual-motor response at 80% of the participant's maximum reach.

研究组 & 干预措施
Athlete Group
This group consists healthy, physically active individuals aged 18-40 who are currently active in sports clubs in Ankara or have applied to the Hacettepe University, Department of Sports Physiotherapy and Rehabilitation. Participants must have been training at least three times a week for the past year and have no history of upper extremity injury or surgery in the last 12 months. This cohort will participate in three separate sessions to assess the feasibility, validity, and test-retest reliability of the neurocognitive test battery.
Non-Athlete Group
This group consists healthy individuals aged 18-40 who meet the general inclusion criteria but do not engage in regular physical activity (defined as exercising fewer than three times a week over the past year). These participants are recruited from healthy individuals applying to the Hacettepe University Sports Physiotherapy and Rehabilitation Unit. This cohort will undergo a single evaluation session to determine the discriminative validity of the test battery by comparing their results to the athlete group.
结局指标
主要结局
Test-Retest Reliability of the Neurocognitive Test Battery
时间窗: Baseline (Session 2) and 1 week later (Session 3)
Evaluated using the Intraclass Correlation Coefficient (ICC) to determine the consistency of scores obtained from the four neurocognitive tests when administered one week apart to the athlete group.
Concurrent Validity
时间窗: During the second evaluation session (approx. 60 minutes).
Measured by analyzing the correlation (Pearson or Spearman coefficients) between the neurocognitive performance test results and physical parameters, including shoulder rotator cuff isometric strength and Rate of Force Development (RFD).
Discriminative Validity
时间窗: Single evaluation session (approx. 60 minutes).
Measured by comparing the neurocognitive performance scores between the athlete group and the healthy control group to determine if the battery can distinguish between different activity levels.
次要结局
- Dual-Task Interference(During the second evaluation session (approx. 60 minutes))
