Validity and Reliability of the 6-minute Pegboard Ring Test in Obese Individuals

Condition(s) studied

Investigational drug(s) / intervention(s)

Patients with obesity: Six-Minute Pegboard and Ring Test: It will be used to evaluate upper extremity exercise capacity. There are 20 rings on 4 iron bars on the board used and patients will be asked to attach the rings with both hands, first from top to bottom and then from bottom to top. At the end of the six minutes, the total number of rings attached will be recorded. Heart rate, blood pressure, respiratory rate, dyspnea and fatigue will be evaluated according to the Modified Borg Scale before and after the test.

Study summary

Obesity is a major public health problem that causes numerous diseases and problems that threaten human health. The prevalence of obesity has increased worldwide in the last \~50 years and has reached pandemic levels. Similar results are seen in Turkey, and according to the results of the Turkey Health Survey, 20.2% of people aged 15 and over were obese and 35.6% were pre-obese in 2022. Obesity represents a major health problem as it significantly increases the risk of diseases such as type 2 diabetes mellitus, fatty liver disease, hypertension, myocardial infarction, stroke, dementia, osteoarthritis, obstructive sleep apnea and various cancers, thus contributing to a decrease in both quality of life and life expectancy. Obesity is also associated with unemployment, social disadvantages and reduced socio-economic productivity, thus representing an increasing economic burden.

Obesity is associated with physiological changes at the muscle level, including a decrease in capillary density and blood flow, thus limiting the supply of oxygen and energy resources. Along with the limited blood flow, muscle cells in obese individuals have a decrease in the relative number and size of mitochondria required for energy supply. This leads to a limitation in upper limb activities.

This activity restriction is related to many activities of daily living that involve unsupported upper extremity movements that lead to dyspnea and fatigue in patients with cardiopulmonary disease. Therefore, determining the strength, endurance and exercise capacity of the upper extremities emerges as an important issue in obesity management. One of the tests that serve this purpose is the 6-minute pegboard ring test (6PBRT), which has been found to be valid and reliable in patients with chronic obstructive pulmonary disease and asthma. However, when the literature is examined, it is seen that 6PBRT has not been studied in obese individuals. Therefore, the aim of the study is to investigate the validity and reliability of 6PBRT in obese individuals.

The main question it aims to answer is:

\- Is 6PBRT a valid and reliable method to assess upper extremity functional capacity in patients wit obesity?

Eligibility

Primary outcome measure(s)

• Six-Minute Pegboard and Ring Test — 1 hour
  Used to evaluate upper extremity exercise capacity. There are 20 rings on 4 iron bars on the board used, and patients are asked to attach the rings with both hands, first from top to bottom and then from bottom to top. At the end of six minutes, the total number of rings attached is recorded. Before and after the test, heart rate, blood pressure, respiratory rate, dyspnea and fatigue will be evaluated according to the Modified Borg Scale.
