How would your life change if you could not use your hands effectively? An estimated 2.7 million people in the UK suffer from a debilitating loss of manual dexterity, which has a dramatic effect on their quality of life. The wrist is the most common site of traumatic injury in the human body, but despite this, treating hand and wrist injuries remains a challenge for the hand surgeon and therapist. Methods of treatment often vary from clinician to clinician and the success of their outcomes is difficult to assess. A reason for this is the complexity of the wrist - it is comprised of eight bones that move relative to those in the forearm and the hand.One method for determining the effects of treatment is to study the forces in the muscles and the motions that result. This can be done using computer models. However, many parameters are needed in order to create a computer model that accurately represents the complex anatomy. An alternative way in which we can evaluate the interactions between the many joints in the hand and wrist, is through the use of joint motion simulators. These simulators replicate joint movement in human specimens by applying forces to the tendons, enabling us to measure the forces in the muscles and joints. This allows us to compare the effects of different surgical and therapeutic procedures in a way that is simply not possible with patient volunteers. In this way we can objectively assess treatment regimens, testing the biomechanical outcomes, before applying them to patients.My research group has developed and tested a joint motion simulator for the wrist that includes six major muscles. However, it is well known that the function of the muscles that control the fingers is highly linked to those that control the wrist. Therefore, the aim of this project is to use our expertise to create a new custom-made joint motion simulator for the wrist that also includes the finger muscles. This work will create a unique and innovative device that possesses greater realism and functionality by enabling us to replicate the motions of the fingers in addition to the wrist. Motors will be used to create the effects of the muscles. Specialised cameras will be used to monitor and control the motion of the joints in real-time. Testing will be performed in collaboration with colleagues in surgery, who will also ensure the clinical impact of the work.The result of this research will produce a device that can be used in the design and testing of implants and other orthopaedic devices, the validation of computational models of the musculoskeletal system, the design of prosthetics, and the training of clinicians.

如果你不能有效地使用你的双手，你的生活会发生什么变化？据估计，英国有270万人患有手灵活性的衰弱，这对他们的生活质量产生了巨大的影响。手腕是人体中最常见的创伤性损伤部位，但尽管如此，治疗手部和手腕损伤仍然是手部外科医生和治疗师的挑战。治疗方法往往因临床医生而异，其结果的成功是难以评估的。这是因为手腕的复杂性-它由八块相对于前臂和手的骨头移动的骨头组成。确定治疗效果的一种方法是研究肌肉中的力和由此产生的运动。这可以通过计算机模型来实现。然而，需要许多参数来创建准确表示复杂解剖结构的计算机模型。我们可以评估手和手腕中许多关节之间的相互作用的另一种方法是通过使用关节运动模拟器。这些模拟器通过向肌腱施加力来复制人体标本的关节运动，使我们能够测量肌肉和关节中的力。这使我们能够比较不同手术和治疗程序的效果，而这在患者志愿者身上是不可能的。通过这种方式，我们可以客观地评估治疗方案，测试生物力学结果，然后再将其应用于患者。我的研究小组已经开发并测试了一种用于手腕的关节运动模拟器，其中包括六块主要肌肉。然而，众所周知，控制手指的肌肉的功能与控制手腕的肌肉高度相关。因此，该项目的目的是利用我们的专业知识为手腕创建一个新的定制关节运动模拟器，其中还包括手指肌肉。这项工作将创造一个独特的和创新的设备，拥有更大的现实主义和功能，使我们能够复制除了手腕的手指的运动。马达将被用来创造肌肉的效果。专门的摄像头将用于实时监控和控制关节的运动。测试将与外科同事合作进行，他们也将确保工作的临床影响。这项研究的结果将产生一种可用于植入物和其他骨科器械的设计和测试，肌肉骨骼系统计算模型的验证，假肢设计和临床医生培训的设备。
