Therapeutic devices that are able to effectively reduce the amount of muscular co-contractions have significant potential in arthritis care. The proof of effectiveness of such devices is today not possible. The surface electromyography as the only non-invasive method for the measurement of muscle activity is subject to strong methodological challenges. These include very high inter- and intra-individual variability, strong susceptibility to noise and cross-talk, and the need for extensive signal processing. Our own preliminary investigations that SEMG, at least in the current state of the technology, is not selective enough to reproducible detect clinically relevant differences in muscular co-contractions.Instrumented orthotics, that allows the measurement of forces and moments between the body segments, are not used in the current arthritis research today. The aim of this project is to develop and to validate new measurement method for assessment the muscular co-contractions in osteoarthritis, based on a combination of instrumented orthosis with SEMG.

能够有效减少肌肉协同收缩的治疗设备在关节炎治疗方面具有巨大的潜力。如今，要证明这种装置的有效性是不可能的。作为唯一一种非侵入性测量肌肉活动的方法，表面肌电图法面临着强大的方法学挑战。这些问题包括个体间和个体内的高度变异性，对噪声和串扰的强烈敏感性，以及需要广泛的信号处理。我们自己的初步研究表明，表面肌电信号至少在目前的技术状态下，没有足够的选择性来重现肌肉收缩的临床相关差异。目前的关节炎研究中没有使用允许测量身体节段之间的力和力矩的器械矫形术。本项目的目的是开发和验证新的测量方法，以评估骨性关节炎的肌肉协同收缩，基于仪器化矫形器和表面肌电信号的组合。
