Abstract

Purpose: This study aimed to estimate the intra- and inter-rater reliability of the JTECH computerized, wireless apparatus and its validity (compared to established devices) for measurements of maximal shoulder isometric strength and handgrip strength among healthy adults with no shoulder pathology. Methods: Twenty healthy young adults had shoulder strength tested with JTECH and Micro-FET2 hand-held dynamometers, and the handgrip strength was tested using JTECH and Jamar handgrip dynamometers. Assessments were performed by the same rater to determine intra-rater reliability and convergent validity, at least two days apart, while on a third visit, the other rater performed measures to determine inter-rater reliability. Results: The JTECH computerized, wireless devices demonstrated good to excellent intra-rater reliability (ICCs (2,1) = 0.78-0.97) and inter-rater reliability for strength measures (ICCs (2,1) = 0.76-0.95). The JTECH computerized device compared to the Micro-FET2 hand-held dynamometer showed substantial concurrent validity for shoulder flexion (R² = 0.87), extension (R² = 0.87), abduction (R² = 0.88), and adduction (R² = 0.85). Substantial concurrent validity was shown for the JTECH computerized device and Jamar handgrip dynamometers (R² = 0.92). Conclusions: The JTECH computerized, wireless devices demonstrated high intra- and inter-rater reliability and substantial concurrent validity for shoulder isometric strength and handgrip strength in healthy adults.

肩部和手部力量测试的可靠性和有效性。

目的：本研究旨在评估 JTECH 计算机化无线仪器的内部和评定者之间的可靠性及其有效性（与现有设备进行比较），以测量无肩部病变的健康成年人的最大肩部等长力量和手握力量。测量方法使用 JTECH 和 Micro-FET2 手持式测力计对 20 名健康的年轻人进行肩部力量测试，并使用 JTECH 和 Jamar 手持式测力计测试手握力量。评估由同一评分者进行，以确定评分者内部信度和收敛效度，至少相隔两天；在第三次访问时，由另一名评分者进行测量，以确定评分者之间的信度。结果：JTECH 计算机化无线设备的评分者内部可靠性（ICCs (2,1) = 0.78-0.97）和评分者间强度测量可靠性（ICCs (2,1) = 0.76-0.95）均达到良好至优秀水平。与 Micro-FET2 手持式测力计相比，JTECH 计算机化设备在肩关节屈曲（R2 = 0.87）、伸展（R2 = 0.87）、外展（R2 = 0.88）和内收（R2 = 0.85）方面显示出很高的并发效度。JTECH 计算机化设备和 Jamar 手握式测力计（R2 = 0.92）显示出很高的并发有效性。结论：JTECH 计算机化无线设备在健康成年人的肩部等长力量和手握力量方面表现出较高的评分者内部和评分者之间的可靠性以及较强的并发有效性。

期刊介绍： Physiotherapy Canada is the official, scholarly, refereed journal of the Canadian Physiotherapy Association (CPA), giving direction to excellence in clinical science and reasoning, knowledge translation, therapeutic skills and patient-centred care. Founded in 1923, Physiotherapy Canada meets the diverse needs of national and international readers and serves as a key repository of inquiries, evidence and advances in the practice of physiotherapy. Physiotherapy Canada publishes the results of qualitative and quantitative research including systematic reviews, meta analyses, meta syntheses, public/health policy research, clinical practice guidelines, and case reports. Key messages, clinical commentaries, brief reports and book reviews support knowledge translation to clinical practice. In addition to delivering authoritative, original scientific articles and reports of significant clinical studies, Physiotherapy Canada’s editorials and abstracts are presented in both English and French, expanding the journal’s reach nationally and internationally. Key messages form an integral part of each research article, providing a succinct summary for readers of all levels. This approach also allows readers to quickly get a feel for ‘what is already known’ and ‘what this study adds to’ the subject. Clinician’s commentaries for key articles assist in bridging research and practice by discussing the article’s impact at the clinical level. The journal also features special themed series which bring readers up to date research supporting evidence-informed practice. The Canadian Physiotherapy Association (CPA) is the national professional association representing almost 15,000 members distributed throughout all provinces and territories. CPA’s mission is to provide leadership and direction to the physiotherapy profession, foster excellence in practice, education and research, and promote high standards of health in Canada.
