Whole Body Vibration Therapy in Individuals With Type 2 Diabetes

Vastus lateralis muscle oxygenation will be evaluated with Near-Infrared Spectroscopy at rest, during and after the 6-Minute Walk Test (6MWT)

The sense of vibration will be assessed with a 128 Hz diapason. The lower end of the device will be brought into contact with the plantar surface of the first metatarsal bone, the medial malleolus, and the medial tuberosity of the tuberositas tibia in both lower extremities of the individual. The moment the diapozone touches the tested areas will be considered as the zero-second (0th second, start), and the test will be terminated when the individual perceives that the vibration disappears completely and the time will be recorded in seconds. Three trials will be performed on the areas in both lower extremities, and the average will be reported.

It is a measurement that evaluates functional mobility, dynamic balance, fall risk and postural stability that can be applied for different purposes in different age and patient groups. The activities that make up the test evaluate the transition from sitting to standing position, walking, turning, and sitting again, which are necessary for functional mobility and dynamic balance. The TUG test measures the time it takes for an individual to get up from a standard chair with armrests and walk a distance of 3 meters, return from a designated or marked place, return to the chair, and sit back down.

The individual is asked to walk on a certain track for 6 minutes. The test is performed in a closed area, on a flat surface of 30 m in length and under the supervision of the evaluator. After six minutes, the total distance walked is recorded in meters.

In a chair with a sitting height of 43.2 cm and a back supported, the patient is asked to sit and stand as quickly as possible. The patient sits in the chair. They cross their hands on their chest. Before the test, 2 attempts are made. The number of sitting down times is noted by keeping a 30-second timer with a stopwatch. Less than 10 sit-ups in 30 seconds indicates lower extremity muscle weakness.

Balance assessment will be performed with the Biodex Balance System (Biodex Medical Systems Inc., Shirley, NY, USA). The static balance test (eyes open-closed) test, which measures the angular movement of the center of gravity, will be used in the study.
