Effect of Bariatric Surgery on Physical Activity, Gait, Flexibility and Quality of Life

Support times

Participants's support times of gait were evaluated by a wearable sensor. The wearable sensor is named BTS G-Walk sensor (BTS Bioengineering S.p.A.,Italy) and was attached L4-5 region by a belt. The data were transferred by Bluetooth connection to software while participants' walking.

Step Length

Participants's step lengths of gait were evaluated by a wearable sensor. The wearable sensor is named BTS G-Walk sensor (BTS Bioengineering S.p.A.,Italy) and was attached L4-5 region by a belt. The data were transferred by Bluetooth connection to software while participants' walking.

Levels of physical activity

Physical activity levels were evaluated by the International Physical Activity Questionnaire- Short Form. This form include seven questions. With these questions, it is possible to obtain information about the time individuals spend in walking, moderate and vigorous activities and also time spent sitting. As a result of the calculations, the level of physical activity is divided into three groups. These groups are as follows: Less than 600 metabolic equivalent-minute inactive; between 600-3000 metabolic equivalent-minute are minimum active; more than 3000 metabolic equivalent-minute are very active.

Sit-Reach Test

The flexibility of the lumbar extensors, hamstrings and gastrocsoleus muscle group was evaluated with the Sit-to-Sit Test. Individuals were asked to sit in a long sitting position, hold their feet in 90 degrees dorsiflexion and reach for their toes with their hands without bending their knees. The test was repeated three times and the mean value was recorded. Positive values were used if this value reached beyond the toes. Higher positive values indicate better flexibility.
