A Reliability of the Prototype Trunk Training System for Sitting Balance

[Purpose] Cerebral palsy is a disorder that affects balance in the sitting position.Cerebral palsy patients need trunk muscle strengthening and balance training. In order toimprove trunk control sensory-motor control training is carried out on an unstablesurface. We have developed a Trunk Training System (TTS) that can provide visual feedbackusing a tilt sensor for balance training in the sitting position. Before using the TTS fortraining children with cerebral palsy experiments were conducted with healthy adultsubjects and the TTS to gather basic data for its improvement. [Subjects] The subjectswere 11 healthy men (n=3) and women (n=8). [Methods] Subjects trained at two levels (5°,10°), in four different directions (anterior, posterior, left, right), three times each.TTS outcome indices (stability index, performance time) were measured. [Results] Thestability index and performance time showed high correlation (−0.6Trunk training system, Reliability, Cerebral palsy
