Standard Framework

The use of haptic devices in rehabilitation of impaired limbs has become rather popular, given the proven effectiveness in promoting recovery. In a standard framework, such devices are used in rehabilitation centers, where patients interact with virtual tasks, presented on a screen. To track their sessions, kinematic/dynamic parameters or performance scores are recorded. However, as Internet access is now available at almost every home, and in order to reduce the hospitalization time of the patient, the idea of doing rehabilitation at home is gaining wide consent. Medical care programs can be synchronized with the home rehabilitation device; patient data can be sent to the central server that could redirect to the therapist laptop (tele-healthcare). The controversial issue is that the recorded data do not actually represent the clinical conditions of the patients according to the medical assessment scales, forcing them to frequently undergo clinical tests at the hospital. To respond to this demand, we propose the use of a bilateral master/slave haptic system that could allow the clinician, who interacts with the master, to assess remotely and in real time the clinical conditions of the patient that uses the home rehabilitation device as the slave. In this paper, we describe a proof of concept to highlight the main issues of such an application, limited to one degree of freedom, and to the measure of the stiffness and range of motion of the hand.

Design And Construction

If one were to identify the most beneficial tangible apparatus for nonverbal individuals, undoubtedly, the communication board would rate highly. For those who are not familiar with the use of such devices, this paper presents the basics of their design, function, and construction. Many variables are considered whenever an individual requires such intermediary devices to enhance and expand expressive language. Selection of the most appropriate language is a primary consideration. In conjunction with language selection, the person's level(s) of functioning need to be assessed both physically and cognitively. Sensorial evaluations are also needed to detect audition problems, agnosia, aphasia, or defective vision. Finally, the construction variables of size, range of motion, costs, and materials must be pre-determined if a functional board is to be produced. Without such planning, the design of hastily derived boards may be as haphazard as its eventual usage.

Abstract Recurrent radiculopathy is evaluated by a different approach in the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, compared to that in the Fourth Edition. The AMA Guides, Fifth Edition, specifies several occasions on which the range-of-motion (ROM), not the Diagnosis-related estimates (DRE) method, is used to rate spinal impairments. For example, the AMA Guides, Fifth Edition, clarifies that ROM is used only for radiculopathy caused by a recurrent injury, including when there is new (recurrent) disk herniation or a recurrent injury in the same spinal region. In the AMA Guides, Fourth Edition, radiculopathy was rated using the Injury Model, which is termed the DRE method in the Fifth Edition. Also, in the Fourth Edition, for the lumbar spine all radiculopathies resulted in the same impairment (10% whole person permanent impairment), based on that edition's philosophy that radiculopathy is not quantifiable and, once present, is permanent. A rating of recurrent radiculopathy suggests the presence of a previous impairment rating and may require apportionment, which is the process of allocating causation among two or more factors that caused or significantly contributed to an injury and resulting impairment. A case example shows the divergent results following evaluation using the Injury Model (Fourth Edition) and the ROM Method (Fifth Edition) and concludes that revisions to the latter for rating permanent impairments of the spine often will lead to different results compared to using the Fourth Edition.

Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, was published in November 2000 and contains major changes from its predecessor. In the Fourth Edition, all musculoskeletal evaluation and rating was described in a single chapter. In the Fifth Edition, this information has been divided into three separate chapters: Upper Extremity (13), Lower Extremity (14), and Spine (15). This article discusses changes in the spine chapter. The Models for rating spinal impairment now are called Methods. The AMA Guides, Fifth Edition, has reverted to standard terminology for spinal regions in the Diagnosis-related estimates (DRE) Method, and both it and the Range of Motion (ROM) Method now reference cervical, thoracic, and lumbar. Also, the language requiring the use of the DRE, rather than the ROM Method has been strengthened. The biggest change in the DRE Method is that evaluation should include the treatment results. Unfortunately, the Fourth Edition's philosophy regarding when and how to rate impairment using the DRE Model led to a number of problems, including the same rating of all patients with radiculopathy despite some true differences in outcomes. The term differentiator was abandoned and replaced with clinical findings. Significant changes were made in evaluation of patients with spinal cord injuries, and evaluators should become familiar with these and other changes in the Fifth Edition.

Combined Injuries

Einleitung: Kombinierte Verletzungen des Capitulum humeri und des Radiusköpfchens sind selten. Meist sind neben den osteocartilaginären Schäden am Gelenk auch Verletzungen der Kollateralbänder assoziiert. Behandlungsempfehlungen für diese seltenen schwerwiegenden Ellenbogenverletzungen fehlen. Studientyp: In einer retrospektiven Analyse werden fünf Fälle untersucht, bei denen die osteocartilaginären Verletzungen des Capitulum humeri durch den gleichen Zugang, der zur Versorgung des Radiusköpfchens verwendet wurde, versorgt wurden. Die Osteosynthese erfolgte mit Mini-Titanimplantaten z.T. kombiniert mit resorbierbaren Pins. Patienten und Methode: Zwischen 1996-1999 wurden fünf Patienten (vier Männer, eine Frau) mit einer Kombinationsverletzung von Radiuskopf und Capitulum humeri operativ stabilisiert. Das Durchschnittsalter beträgt 34 Jahre (31-40 Jahre). Alle Frakturen wurden über einen direkten radialen Zugang mittels 1.5mm oder 2.0mm Zugschrauben, zum Teil mit resorbierbaren Pins stabilisiert. Anschliessend wurden die Patienten radiologisch und klinisch gemäss dem Mayo-elbow-performance Score beurteilt. Resultate: Alle Patienten konnten persönlich durch einen nicht in die Initialtherapie involvierten Untersucher nach durchschnittlich 12.8 Monaten (8-24 Monate) nachuntersucht werden. 4/5 Patienten konnten bezüglich ihrer subjektiven Einschätzung befragt werden. Radiologische Zeichen einer Nekrose des Capitulum humeri oder Arthrosezeichen fanden sich nicht. Bei drei Patienten fanden sich periartikuläre Verkalkungen. Der range of motion beträgt durchschnittlich 124 Grad (Extension 5-30 Grad, Flexion 110-145 Grad) in drei von fünf Fällen waren Sekundäreingriffe zu Mobilitätsverbesserung nötig. Der Mayo-elbow-performance Score beträgt im Mittel 85 Punkte (range 70-100 Punkte). Schlussfolgerung: Die direkte Verschraubung mit Miniimplantaten zum Teil in Kombination mit resorbierbaren Pins ermöglicht eine stabile anatomische Rekonstruktion des Capitulum humeri durch den gleichen Zugang wie er für die Stabilisierung des Radiusköpfchens notwendig ist. Die transartikuläre Fixation der kleinen Schalenfragmente des Capitulum humeri erlaubt eine sichere interfragmentäre Kompression und damit eine frühfunktionelle Rehabilitation. Sekundäreingriffe zur Verbesserung der Gelenkbeweglichkeit waren in drei von fünf Fällen nötig.
