BACKGROUND
The alteration of forces across joints can result in instability and subsequent disability. Previous methods of force measurements such as pressure-sensitive films, load cells, and pressure-sensing transducers have been utilized to estimate biomechanical forces across joints and more recent studies have utilized a nondestructive method that allows for assessment of joint forces under ligamentous restraints.
METHODS
A comprehensive review of the literature was performed to explore the numerous biomechanical methods utilized to estimate intra-articular forces.
RESULTS
Methods of biomechanical force measurements in joints are reviewed.
CONCLUSIONS
Methods such as pressure-sensitive films, load cells, and pressure-sensing transducers require significant intra-articular disruption and thus may result in inaccurate measurements, especially in small joints such as those within the wrist and hand. Non-destructive methods of joint force measurements either utilizing distraction-based joint reaction force methods or finite element analysis may offer a more accurate assessment; however, given their recent inception, further studies are needed to improve and validate their use.
背景
关节受力的改变会导致不稳定及随后的功能障碍。以往的力测量方法，如压敏薄膜、测力传感器和压力传感换能器，已被用于估计关节的生物力学力，并且最近的研究采用了一种无损方法，该方法允许在韧带约束下评估关节力。
方法
对文献进行全面综述，以探索用于估计关节内力的众多生物力学方法。
结果
对关节生物力学力测量方法进行了综述。
结论
诸如压敏薄膜、测力传感器和压力传感换能器等方法需要显著的关节内破坏，因此可能导致测量不准确，特别是在诸如手腕和手部内的小关节中。利用基于牵张的关节反作用力方法或有限元分析的关节力测量无损方法可能提供更准确的评估；然而，鉴于它们最近才开始应用，需要进一步研究以改进和验证其用途。
