  • Title: Clinical evaluation of a new biofeedback standing balance training device.
    Author: Lee MY, Wong MK, Tang FT.
    Journal: J Med Eng Technol; 1996; 20(2):60-6. PubMed ID: 8836924.
    Abstract:
    For patients with neurological damage of the central nervous system, such as that due to cerebrovascular accident (CVA), standing balance training is a critical therapeutic procedure to be undertaken before walking and self-care training. The identification and characterization of neurological disorder in postural steadiness will enhance our understanding of the postural control system, and help to identify patients at risk of falls in the CVA population. This paper discusses the design and clinical evaluation of a new biofeedback training device for static (postural steadiness) performance of the standing balance system. The device includes a height adjustable standing table, an instrumented force sensing platform, an on-line weight bearing audio/visual biofeedback system, a postural correction mirror, and a belt suspension system for the upper extremities. A quantitative evaluation protocol of bilateral asymmetries in weight distribution and postural sway to characterize standing balance with the force sensing platform is discussed. Finally, the clinical evaluation results of sixty patients with hemiplegia from acute stroke for a period of four weeks are discussed. With this economic standing training device, the static standing steadiness can be trained effectively through weight bearing biofeedback and a postural correction mirror in the clinical and home caring environments.
