Not yet recruiting
Conditions
Idiopathic Pulmonary Fibrosis (IPF)
Registration Number
NCT06756230
Lead Sponsor

Brief Summary

In this study; will examine the effects of downhill walking (eccentric exercise training) on exercise capacity, quality of life, and blood lactate levels in individuals with IPF. After the initial assessment, patients will be randomized into two groups: downhill walking PR group and Standard PR Group.

Detailed Description

Individuals diagnosed with idiopathic pulmonary fibrosis who come to the Pulmonary Rehabilitation Unit of Istanbul Süreyyapaşa Chest Diseases and Chest Surgery Education and Research Hospital will be included in this study. Those who meet the inclusion criteria will be randomized into two groups: Downhill Walking Pr Group (n=17) and Standard Pr Group (n=17). Patients will have exercise sessions twice a week for 8 weeks. Patients will be evaluated immediately before the rehabilitation program and the end of 8 weeks exercise programme. In our study, downhill walking training will differ from traditional walking training only in terms of treadmill training protocol. Traditional walking training involves walking on a motorized treadmill with a neutral incline, progressing with increases in speed, while downhill walking training will be performed at a constant -10% incline.

Primary Outcome Measures
NameTimeMethod
6 Minutes Walking Distance (6MWD)Baseline and the end of the 8 weeks exercise program

6 MWD means the distance the patient walked in 6 minute walk test. Its unit is meters.

Saint George Quality of life questionnaireBaseline and the end of the 8 weeks exercise program

The St. George's Respiratory Questionnaire (SGRQ) is designed to measure quality of life. Four scores are calculated Symptoms, Activity, Impacts, and Total. Saint George Respiratory Questionaire (SGRQ) score: The SGRQ ranges from 0 (no impairment of quality of life) to 100 (highest impairment of quality of life).

Secondary Outcome Measures
NameTimeMethod
Spirometric measurements (Forced vital capacity)Baseline and the end of the 8 weeks exercise program

It is used to evaluate respiratory functions. It is evaluated with a spirometer. Forced vital capacity (FVC): the maximum amount of air that can be forcibly exhaled from the lungs after fully inhaling. It can be recorded in percentages or liters.

Spirometric measurements (First second forced expiratory volume)Baseline and the end of the 8 weeks exercise program

It is used to evaluate respiratory functions. It is evaluated with a spirometer. First-second forced expiratory volume (FEV1): the amount of air that can be exhaled with force in 1 second. It can be recorded in percentages or liters.

Spirometric measurements (FEV1/FVC ratio)Baseline and the end of the 8 weeks exercise program

It is used to evaluate respiratory functions. It is evaluated with a spirometer. It is calculated by dividing FEV1 by FVC. It is expressed as a percentage.

Peripheral muscle strengthBaseline and the end of the 8 weeks exercise program

Peripheral muscle strength will be assessed using a digital dynamometer. Quadriceps femoris muscle strength; will be measured by applying maximum resistance 2-3 cm above the ankle malleolus of the patients in a sitting position using an digital dynamometer.

Hand grip strengthBaseline and the end of the 8 weeks exercise program

Hand grip strength will be assessed in a sitting position. During the test, the arm will be measured next to the body, with the shoulder adducted, the elbows flexed at 90°, the forearm and wrist in a neutral position, and patients will be asked to grip and release the dynamometer as strongly as possible, and the measurement will be repeated 3 times on both dominant and non-dominant extremities and the averages will be recorded. A one-minute rest will be given between each trial.

Modified Medical Research Council Dyspnea ScoreBaseline and the end of the 8 weeks exercise program

Modified Medical Council Dyspnea score will rate the sensation of dyspnea as the person perceives it.The severity of dyspnea is rated on a scale of 0 to 4."0 point" means no dyspnea perception and "4point" means severe dyspnea perception.

Fatigue severity scaleBaseline and the end of the 8 weeks exercise program

Fatigue levels of individuals will be assessed with the Fatigue Severity Scale (FSS). The FSS consists of 9 questions scored using a 7-point Likert scale, indicating a perception of fatigue that may require medical intervention.

Hospital anxiety depression scale (HADS)Baseline and the end of the 8 weeks exercise program

A scale consisting of 14 items developed by Zigmond and Snaith. Seven of these items evaluate anxiety symptoms and seven evaluate depression symptoms. The items in the scale are evaluated with a 4-point Likert scale and are based on a scoring system between 0-3.

Determination of blood lactate levelBaseline and the end of the 8 weeks exercise program

Blood lactate level will be measured by fingertip sample using a portable lactate meter after a standardized exercise protocol applied before and after the intervention. Blood samples will be recorded in mmol/L after being analyzed by the device.

Carbon monoxide diffusion capacityBaseline and the end of the 8 weeks exercise program

Carbon monoxide diffusion capacity (DLCO) is the measurement of the passage of carbon monoxide gas in inspired air into the lung capillary blood. Diffusion test is performed in the pulmonary function test laboratory.
