“…Demura et al [23] reported that ICCs of the step test with maximal effort on the spot were over 0.9. Hashidate et al [38] proposed the modified step test to measure the time required for repeated lateral stepping (5 times ) on 10 cm high plates , and reported that the ICCs were also over 0.9 in any direction. Moreover, Shin and Demura [22] reported that the ICC of the time difference between foot contact on the spot and a stipulated tempo of 40 bpm was 0.73.…”

This study aimed to examine trial-to-trial reliability of a new clinical test, rapid reaction step cued on a screen test, and its relationship with fall risk score, independence in activity of daily living score, and various leg muscle function tests. One-hundred fifty seven older women participated in this study. Nine square plates (32 × 32 cm) were lined up with three plates. Participants stood on a center plate and were instructed to step, using one leg, to one of the other eight plates, as quickly as possible, when that plate changed in color from white to red. The mean total time and the mean total error time of rapid reaction step cued on a screen and, fall risk score, activity of daily living score, lower muscle function (isometric muscle strength: toe flexion, plantar flexion, knee extension, hip flexion; balance: one leg standing time with eye open, functional reach test; gait: 10 m walk time with maximal speed). Results: trial-to-trial reliabilities of step parameters were high (intraclass correlation coefficient [ICC] = 0.75 -0.85). The step parameters correlated significantly with the other parameters except for toe flexion and hip flexion strengths. In conclusion, the present step test was found to evaluate physical function related to prevention of falls in older people.

Objectives: To examine the reliability and fall experience discrimination of the Cross Step moving on Four spots Test (CSFT) including a rapid crossover steps and the relationship between the CSFT scores and the fall-related physical function.Design: The reliability of the CSFT was examined in a test-retest format with the same tester. Results: The trial-to-trial reliability test indicated good reliability of the CSFT in both sexes (intraclass correlation coefficient = 0.833 in men, 0.825 in women). However, trial-to-trial errors increased with increase in the CSFT values in both sexes. Significant correlations were observed between the CSFT values and scores for most fall-related physical function tests in both sexes. However, the correlation coefficient for all significant correlations was <0.5. Two-way analysis of variance (sex × fall experience) revealed that the fall experience is a 1 significant factor affecting the CSFT values; the values in fallers were significantly lower than those in nonfallers. The odds ratios in logistic regression analysis were significant in both sexes (men: 1.35, women: 1.48). As determined by Youden's index, the optimal cutoff value for identifying fall experience was 7.32 s, with an area under the curve of 0.676. Conclusion:The CSFT can detect fall experience and is useful in the evaluation of different fall-related physical functions, including muscle strength, balance, and mobility.

Purpose] The aim of this study was to evaluate the reliability, validity and clinical utility of the basic balance ability test (BBT) which we designed.[Subjects] Subjects were 122 patients with balance disorders hospitalized in five hospitals.[Methods] The BBT is composed of 25 tasks which are divided into three balance levels, including static balance, weight-shifting in the sitting and standing positions, step movement, and standing up from a therapeutic bed and sitting down. Each task was scored on a 3-point scale, 0 to 2, according to the stability levels of performance. Reliability of the BBT was evaluated by the test-retest method. The validity of the BBT was evaluated using the correlation between the total score of the BBT and the Berg balance scale (BBS). The utility of the BBT was assessed by the measurement time of BBT, and the relation between BBT and gait ability of the patients.[Results] The average ratio of agreement between two measurements was 81.6%. The correlation coefficient between the BBT and the BBS was 0.88. The mean measuring time for BBT was 8.6 minutes. And the total score of the BBT changed in accordance with the gait ability of the patients. [Conclusion] From the above results, we conclude that BBT has reasonable reliability, validity and clinical utility. 要旨：〔目的〕パフォーマンスに基づくバランス能力評価指標(以下，基本バランス能力テスト)を考案し，その信頼性，妥当性，および臨床における実用性を検討することを目的とした。〔対象〕検査対象者総数は種々の疾患によりバランス能力低下を呈する患者122 名であった。〔方法〕基本バランス能力テストは，端座位における姿勢保持と重心移動，立位における姿勢保持・重心移動・ステップ動作，および立ち上がり動作を検査課題とした。検査項目は25 項目とし，各項目を不可：0 点，不安定：1 点，安定：2 点で評定し，合計で 50 点満点とした。信頼性は理学療法士20 名が 3ヵ月おいて 2 回測定を実施し，検査項目の評定の一致度を調査した。妥当性は Berg balance scale との相関により検討した。実用性は基本バランス能力テストの測定に要する時間，歩行能力との対応関係より検討した。〔結果〕再評価の各検査項目の一致率は平均で81.6 ± 10.9％であった。Berg balance scale との相関はｒ＝0.88(p ＜ 0.01)であった。測定時間は平均で 8.6 ± 5.2 分であり，合計点は対象者の歩行能力に従って推移した。〔結語〕以上の結果，考案した基本バランス能力テストは臨床的なバランス能力評価指標として有用と考えた。キーワード：バランス能力，臨床的評価指標，臨床的実用性 1) 文京学院大学保健医療技術学部：埼玉県ふじみ野市亀久保1196(〒356-8533)TEL 049-261-7891 2) 首都大学東京健康福祉学部受付日 2008年11月20日受理日 2009年1月7日
