During the last 40 years, there have been revolutionary advances in power wheelchairs. These unique wheelchair systems, designed for the physically immobile patient, have become extremely diversified, allowing the user to achieve different positions, including tilt, recline, and, more recently, passive standing. Because of this wide diversity of powered wheelchair products, there is a growing realization of the need for certification of wheeled mobility suppliers. Legislation in Tennessee (Consumer Protection Act for Wheeled Mobility) passed in 2003 will ensure that wheeled mobility suppliers must have Assistive Technology Supplier certification and maintain their continuing education credits when fitting individuals in wheelchairs for long-term use. Fifteen other legislative efforts are currently underway in general assemblies throughout the US. Manufacturers, dealers, hospitals, and legislators are working toward the ultimate goal of passing federal legislation delineating the certification process of wheeled mobility suppliers. The most recent advance in the design of powered wheelchairs is the development of passive standing positions. The beneficial effects of passive standing have been documented by comprehensive scientific studies. These benefits include reduction of seating pressure, decreased bone demineralization, increased bladder pressure, enhanced orthostatic circulatory regulation, reduction in muscular tone, decrease in upper extremity muscle stress, and enhanced functional status in general. In February 2003, Permobil, Inc., introduced the powered Permobil Chairman 2K Stander wheelchair, which can tilt, recline, and stand. Other companies are now manufacturing powered wheelchairs that can achieve a passive standing position. These wheelchairs include the Chief SR Powerchair, VERTRAN, and LifeStand Compact. Another new addition to the wheelchair industry is the iBOT, which can elevate the user to reach cupboards and climb stairs but has no passive standing capabilities. In addition, the physically immobile patient must be seated on an ERGODYNAMIC Seating System 2000, which is inflated by the alternating pressure compressor 8080. This seating system has a deep center seam between the two ischial-support chambers, which provides a recess for the coccyx. The pre-ischial crossbar compartment inflates during each cycle to prevent the pelvis from slipping forward. It is essential that the physician of the immobile patient order two ERGODYNAMIC Seating Systems 2000 because the patient must have an additional seating system in the case one leaks. Moreover, two compressors are necessary because each compressor must be serviced after 2500 hours of use. For the protection of the consumer, these pressure relief systems must be supplied and serviced by a Certified Rehabilitation Technology Supplier such as Wheelchair Works Inc. Despite the indisputable scientific evidence of the medical benefits of passive standing for the immobile user, few individuals have access to these revolutionary wheelchairs. Consequently, it is mandatory that the medical community, headed by specialists in physical and occupational therapy as well as rehabilitation medicine, CRTS, and manufacturers collaborate in a national education campaign to convince Medicare/Medicaid and all commercial insurance companies to approve immediately these assisted technologies. This program is essential so that the physically immobilized patient can achieve the undisputed physical benefits of passive standing.
在过去的40年里,电动轮椅取得了革命性的进展。这些专为身体不能活动的患者设计的独特轮椅系统变得极为多样化,能让使用者实现不同姿势,包括倾斜、后仰,以及最近出现的被动站立。由于电动轮椅产品种类繁多,人们越来越意识到有必要对轮式移动设备供应商进行认证。田纳西州于2003年通过的立法(《轮式移动设备消费者保护法》)将确保轮式移动设备供应商必须具备辅助技术供应商认证,并在为长期使用轮椅的个人进行适配时保持继续教育学分。美国各地的州议会目前正在进行另外15项立法工作。制造商、经销商、医院和立法者正在朝着通过联邦立法来界定轮式移动设备供应商认证程序的最终目标努力。电动轮椅设计的最新进展是被动站立姿势的开发。全面的科学研究已经证明了被动站立的有益效果。这些益处包括减轻座位压力、减少骨质流失、增加膀胱压力、增强直立循环调节、降低肌肉张力、减轻上肢肌肉压力以及总体上提高功能状态。2003年2月,Permobil公司推出了电动的Permobil Chairman 2K Stander轮椅,它可以倾斜、后仰和站立。其他公司现在也在生产能够实现被动站立姿势的电动轮椅。这些轮椅包括Chief SR Powerchair、VERTRAN和LifeStand Compact。轮椅行业的另一项新成员是iBOT,它可以将使用者升高以够到橱柜和爬楼梯,但没有被动站立功能。此外,身体不能活动的患者必须坐在ERGODYNAMIC Seating System 2000上,该座椅由交替压力压缩机8080充气。这个座椅系统在两个坐骨支撑腔之间有一条深深的中央接缝,为尾骨提供了一个凹槽。坐骨前横杆隔层在每个周期充气以防止骨盆向前滑动。不能活动的患者的医生必须订购两台ERGODYNAMIC Seating System 2000,因为如果一台漏气,患者必须有额外的座椅系统。此外,需要两台压缩机,因为每台压缩机在使用2500小时后都必须进行维修。为了保护消费者,这些减压系统必须由经过认证的康复技术供应商(如Wheelchair Works Inc.)提供和维修。尽管有确凿的科学证据表明被动站立对不能活动的使用者有医疗益处,但很少有人能使用这些革命性的轮椅。因此,必须由物理治疗、职业治疗以及康复医学方面的专家、CRTS和制造商牵头,医疗界开展一场全国性的教育活动,说服医疗保险/医疗补助机构以及所有商业保险公司立即批准这些辅助技术。这个项目至关重要,这样身体不能活动的患者才能获得被动站立带来的无可争议的身体益处。
