  • influence of Spine Orthosis and sit to stand motor strategies on ground reaction force and lower extremity muscle activity
    2006
    Co-Authors: Dokyun Kim, Tackhoon Kim, Jungsuk Roh, Heonseock Cynn
    Abstract:

    The purpose of this study was to assess the influence of Spine Orthosis and sit-to-stand motor strategies on ground reaction force (GRF) and lower extremity muscle activity. Twenty healthy adult men participated, and subjects randomly performed sit-to-stand motions in three different conditions: Momentum-transfer strategy (MTS); MTS with Spine Orthosis; and zero-momentum strategy (ZMS) with Spine Orthosis. GRF data, onset time, and muscle activity were determined and compared using force plate and electromyography. Data were statistically analyzed by the SPSS version 13.0. One-way repeated analysis of variance (ANOVA) was used to determine the statistical significance, and least significant difference was used as a post hoc test. The level of significance was .05. The results of this study were as follows: 1. Peak GRF and relative time to peak GRF were not significantly different in the three different conditions (p>.05). 2. Onset time of four muscles, tibialis anterior, gastrocnemius, biceps femoris and rectus femoris, in the three different conditions were significantly different (p

  • British Journal of Rheumatology 1996;35:771-774 A STIFF COLLAR FOR THE TREATMENT OF RHEUMATOID ATLANTOAXIAL SUBLUXATION
    2014
    Co-Authors: M. Kauppi, P. Anttila
    Abstract:

    Conservative treatment of atlantoaxial subluxation (AAS) has tended to be rather passive, since there has been a lack of effective tools. The stabilizing effect of a stiff collar in the treatment of AAS was evaluated. Fifty successive rheumatoid patients with unstable AAS were interviewed and examined clinically. Lateral view radiographs of the cervical Spine were taken in neutral position, during flexion and extension without a collar, and during flexion with a stiff collar. Seventeen patients did not have cervical symptoms. A stiff collar was able to significantly stabilize AAS in more than half of the cases, the effect being predictable from neutral-position radiographs. The improvement in bearing enhanced the effect of the collar. The means and strategy of conservative treatment of AAS are discussed. KEY WORDS: Atlantoaxial subluxation, Atlantoaxial joints, Cervical Spine, Orthosis, Rheumatoid arthritis. ATLANTOAXJAL subluxation (AAS) is a common and significant abnormality in rheumatoid arthritis (RA) [1-4], with a reported prevalence of between 19 and 70 % in RA patients [3]. It was found in 33 % of a population-based series of RA patients [4]. The rheumatoid inflammatory process often injures the stabilizing structures of the atlantoaxial area i
