The dynamic gait parameter will be assessed with the BTS G-Walk Device, a wearable movement analysis system. The BTS G-Walk sensor system is a wireless magnetic sensor device that can be used to determine spatio-temporal parameters as well as pelvic movements during walking. The system consists of many parameters that analyze movements such as walking, running and jumping. In gait analysis, this system compares bilateral right and left limbs with normal values, and provides kinematic analysis of the pelvis in 3 planes.

The test will be performed along a 30 meter long by 1.5 meter wide corridor according to standard procedures developed by the American Thoracic Society. Participants will be instructed to walk along the 30-meter corridor from the starting point to the end at the best speed they can within 6 minutes, using standard encouragement phrases at the beginning of each minute. Modified Borg Scale will be used for dyspnea and leg fatigue perception. At the end of the test, the total distance covered will be recorded in meters (m). The calculation of percentage values will be based on the reference values formulated by Enright et al. in healthy population.

To assess intermittent claudication, the Turkish adaptation of the 21-item self-report scale Decreased Walking Distance Scale developed by Dr. Regensteiner et al. (1995) will be used. The scale consists of claudication, differential diagnosis, distance, speed and stair parameters. The sub-parameters (distance, speed and stairs) are rated on a Likert scale ranging from 0 (unable, very difficult) to 4 (no difficulty at all) and each item has a weighted score. The claudication and differential diagnosis section is assessed individually, while the subscales are assessed on a scale of 0 to 100 points, calculated according to the weight of each question. The subscale score is obtained by dividing the Likert scale score by the maximum weighted score and multiplying by 100. Each subscale score is evaluated between 0-100. A high score indicates high performance. Total and combined scores are calculated by averaging the subscales.

The physical activity enjoyment scale is an 18-item scale developed to assess the enjoyment of physical activity in young adults (Kendzierski & DeCarlo, 1991). The short form of the physical activity enjoyment scale (8 questions) was adapted from the original 18-item scale by Raedeke. The Turkish validity and reliability of the scale was conducted by Soylu et al. The Exercise Enjoyment Scale consists of 8 items with a 7-point Likert-type rating and a single dimension. The scale evaluates positive emotions such as enjoyment and pleasure from exercise. A high mean score on the scale indicates that the level of enjoyment from exercise is high, while a low mean score on the scale indicates that the level of enjoyment from exercise is low.
