4 远程康复 第一篇——概述 Teamwork Two groups are loosely defined as the TeleRehab “experts” or specialists and those at TeleRehab personnel “rural” sites. However it is very important to understand that in order for the client to receive the best care the “expert” and the rural individuals are members of a team each of whom has different and equally pertinent information vital to a good outcome. Constituencies It is generally assumed that the two groups would be split as indicated in the slide, but it may well be that there is considerable overlap, depending on local resource issues. That is, in a particular health care system, who are the health care providers visiting clients in their homes or places of work.

6 远程康复- 需求 资源与距离 大约 200 英哩 宾州- 西部/中心 没有足够的熟练人员 大量的服务不周 过于遥远 病人过早出院 死亡率
伤残率 帮助技术 The major issues revolving around the need can be summarized simply as distances, lack of local expertise, high cost of delivery in rural areas. The problems of delivery of Rehabilitation Service provision in rural areas parallels the delivery of health care to rural areas where the proportion of people with chronic illnesses is higher and the means to pay for them is reduced services (Witherspoon, Johnston, & Wasem, 1993). Large distances mean long travel times increasing costs associated with any service delivery and the time of travel consumes valuable time skilled professionals could be using to provide services. 大约 200 英哩 宾州- 西部/中心

7 远程康复- 为什么使 用基于电话的系统? AT&T, top picture 1994 ($1500) 性能差 ViaTV, 1998
1998, 普遍使用的基础部件 (POTS)- 价廉，性能好。如 ViaTV, Starview 新部件：价格超过300美元 The potential of modern low cost technologies as tools in the delivery of Assistive technology have been discussed (Shapcott, 1994). An example of the technology of the time was shown, the AT&T video phone- this was little better than an ordinary phone call in getting information to a remote party because of small picture size, low resolution and slow frame rates. New low cost POTS based video conferencing technologies are appearing rapidly. These are based around low cost digital video chips and sophisticated video compression techniques. These can cost little as approximately $400 (US) for each unit. See picture below. The units consist of a camera and all required electronics in a small box and are relatively easy to use. These systems are now able to transmit and receive reasonable video images and are being further developed to accept RS232 computer inputs which have the potential of enabling the transmission of accompanying electronic data.

8 远程康复的潜在效益 为居住在大城市外的人提供更方便的健康监护 缩短病人与医师到诊所和医院的路程 更多专家可参与到诊断评价
对出院病人实现疗效随访跟踪

9 远程康复 第二篇 —— 技术术语 This lecture is designed to introduce you to the main features and concepts that we currently understand about TeleRehabilitation. 1. Overview of Telemedicine and TeleRehabilitation 2. Technologies and nomenclature 3. Report on local findings 4. Future developments 5. Opportunity for interactive web based discussion

10 带宽- (信息速率) 已有和正在发展的技术 有线-T/4 光缆- 高带宽 有线 -ISDN 数字电话线- 中等带宽
有线 -POTS- 简单电话服务- 低带宽 有线 –Cable- 中等/高带宽 有线 - Power Utilities- 未知 有线 - *DSL 技术- 中等/高带宽 无线- Cell Phone 3G- 中等/高带宽 无线- 2 Way Satellite (0.5m)- 中等/高带宽 Bandwidth can be imagined as being analogous to the internal diameter of a water pipe, the larger the diameter the more water will flow- thus the larger the bandwidth the more data can flow and in this case, the better the video. Compression is a mathematical technique used in the software and hardware which uses "tricks" to squeeze better quality video for a particular available bandwidth. Technologies listed here are as of 1999 and by observation change on a 3-6 month cycle with new technologies appearing and old ones fading out. As time passes some of the older technologies repackaged an reappearing at more advantageous times.

13 临床讨论的问题 谁对病人的安全性负责 具体操作的人 帮助移动的人 培训 指挥操作的人和具体操作的人要资格认证
双方都要接受专业培训，建立相互默契和理解 远程康复在认知上的限制来源于 没有触觉 去感受病人运动的范围 不能感受病人的抖动 需要更多的工具 ，如压力计等 需要多视角观察

14 用有线电话远程康复系统 评价轮椅系统处方的功效
目标与方法 为使用有线电话传输声、光信号来进行辅助技术远程处方服务的电视会议系统建立评价其可靠性与局限性的科学基础。 确定在由于地理、交通、经费原因而不能提供良好服务的社区中，增加辅助技术的处方服务能力的潜力。 用远程康复系统对患者所需轮椅或座位进行评价，并与现场康复评价的结果相比较。

15 用有线电话远程康复系统 评价轮椅系统处方的功效
研究问题 有经验的临床医师用远程康复技术和已定义的操作协议能否： 可靠地确定远程康复流程对特殊病人是否合适而安全？ 可靠地、在细节水平上提供关于所需轮椅精确决定？ 可靠地获取关于病史与体检结果的准确评估？

16 用有线电话远程康复系统 评价轮椅系统处方的功效
评估 面谈-从标准信息表获得病人信息以组成“模 型患 者”；与患者面谈确定灵活的目标、目标的合适性、诊断以及身体健康状况的任何变化。 坐垫评价- 由临床医师亲自进行运动测量评价或通过远程康复系统由临床医师指导助手进行评价。坐垫评价的目标是建立被动和主动的上、下肢运动范围、任何病理移动方式、坐姿和移动技术、脊椎定向，及与运动和其它目标相关的功能性能力。 测量- 临床医师或其助手用数据收集表要求记录线性或角度测量结果。
