Determinants of Balance in Patients With Chronic Obstructive Pulmonary Disease

July 4, 2023 updated by: Hikmet Ucgun, Biruni University
The primary aim of our study is to examine the relationship between balance and respiratory function, respiratory and peripheral muscle strength, functional capacity, and cognitive function in patients with Chronic Obstructive Pulmonary Disease (COPD). The secondary aim of our study is to compare respiratory function, respiratory and peripheral muscle strength, functional capacity, balance, and cognitive functions of COPD patients and healthy individuals. This study will examine and record the participant's sociodemographic information and medical records. Balance, respiratory function, respiratory and peripheral muscle strength, functional capacity, and cognitive function will be assessed. Since the patients are included in this study, no intervention will be made, no additional tests will be performed, or no changes will be made in the routine treatments of the patients during the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Patients with COPD aged between 40-65 years and healthy adults aged between 40-65 years will be included in the study. Informed consent forms for the study prepared for both the COPD group and the control group will be carefully explained and the participants will be included in the study after they have read, understood, and accepted.

Cohorts and Interventions

Group / Cohort

Group / Cohort

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
COPD Group
Balance assessment, Pulmonary function test, Respiratory muscle strength test, Peripheral muscle strength test, 6-minute walk test, Cognitive assessment
Other: Balance Assessment
Balance assessment will be done with the "Biodex Balance System®" (Biodex Medical Systems, Shirley, New York, United States). Postural stability test overall score, stability limits test overall score, and sensory integration test of balance composite score will be recorded.
Other: Pulmonary function test
Pulmonary function test will be performed with a spirometer ("COSMED Pony FX" (COSMED; Italy) in accordance with ATS/ERS criteria. Forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, peak expiratory volume measured at 25% and 75% of forced expiratory time (FEF 25-75%), and peak expiratory volume (PEF) parameters will be measured. The results will be recorded both as a percentage of measured values and expected values.
Other: Respiratory muscle strength test
Respiratory muscle strength will be measured in accordance with ATS/ERS criteria using an electronic, mobile, (MicroRPM, Micro Medical; UK) intraoral pressure measuring device. Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) values will be recorded. Three measurements will be repeated for each maneuver and the highest value recorded as cmH2O.
Other: Peripheral muscle strength test
Peripheral muscle strength will be assessed by measuring M. Quadriceps muscle strength with a digital handheld dynamometer (MicroFET® Hoggan Scientific; USA). The test will be done in three measurements for the dominant side lower extremity. The average of the obtained values will be recorded in kilograms.
Other: 6-minute walk test
Functional capacity will be assessed with the 6-minute walk test (6MWT). 6MWT will be performed in accordance with the criteria of the American Thoracic Society. The 6MWT distance will be recorded in meters.
Other: Cognitive assessment
Cognitive function will be assessed with the Montreal Cognitive Assessment (MoCA) test. The MoCA test is a questionnaire developed to evaluate different cognitive functions and mild cognitive impairment. The maximum score that an individual can obtain from the test is 30, and a score of 21 or above is considered as mild cognitive impairment. Test; will be administered by a certified physiotherapist who has received training on practice and scoring directives
