Introduction. A number of diseases, namely atrophy, paralysis, including neuromuscular spinal deformities and spinal muscular atrophy, ankylosing spondylitis, impose special medical and technical requirements on the design and appointment of wheelchairs.
Aim. Registration of physiological movements in the cervicothoracic and thoracolumbar spine segments at the entrance and exit of the ramp.
Materials and methods. During the study, the movements of a person in a wheelchair were recorded at the entrance to the ramp with a tilt angle of 13 degrees, and exit from it, with the help of an assistant. The movement was registered using the H.MotionLab research complex, which includes the Kinect v.2 sensor. The study involved 5 healthy people and 5 people with disabilities and disabled children who use the wheelchair on a daily basis.
Results. It was established that the moment of occurrence of physiological stabilization movements (the moment of changing the position of the head relative to the horizon in the sagittal plane) is clearly defined when entering the ramp, and when leaving it at a speed of 0.4 m/s. At the exit at a higher speed, the reflex tension of the muscular corset of the body occurs, stabilization of the head position occurs with a delay.
Conclusion. Objective data on movements in the cervicothoracic and thoracolumbar spine in the sagittal plane were obtained at the entrance and exit of the ramp. The data can be used in the design of wheelchairs with a seat position stabilization system, namely in the formation of technical requirements for the sensitivity and speed of the adaptation mechanism of the position.
