Differences in wheelie maneuver performance in wheelchair users with different trunk motor control

Differences in Wheelie Performance in Manual Wheelchair Users with Varying Trunk Motor Control The wheelie represents one of the key skills necessary for the independence and mobility of manual wheelchair users. Trunk control is considered one of the factors influencing the success of this manoeuvre. However, the manner in which it affects the wheelie and its biomechanical parameters has not yet been sufficiently described. The aim of this study was to analyse the course of the wheelie in wheelchair users with differing levels of motor trunk control. The study included ten participants who were divided into two groups based on the results of the Manual Muscle Test (MMT > 80 %; MMT < 10 %). Both groups included participants with spinal cord injury, and the sample also comprised individuals with amputations, arthrogryposis, or transverse myelitis. Each group included at least one female participant. All participants performed five repetitions of the wheelie manoeuvre. During these trials, five IMU sensors were used to evaluate five key biomechanical parameters: trunk position, trunk angular velocity, wheelchair tilt angle, angular velocity of wheelchair tilt, and angular velocity of the rear wheels. The results indicated that both groups were able to perform the wheelie manoeuvre in a stable manner....
