Eye patching in unilateral spatial neglect : Efficacy of two methods

OBJECTIVES To determine whether patches obscuring half the visual field affect eye movement in subjects with unilateral spatial neglect and whether there is consequent improvement in the subjects everyday life, and to interpret the potential changes observed with the aid of a theoretical model. DESIGN Prospective and randomized study. SETTING Rehabilitation medicine department in an urban general hospital. PATIENTS Twenty-two subjects with left unilateral neglect. INTERVENTION Two eye-patching procedures-right half-field patches (n = 7) and right mononuclar patch (n = 7)-and control group (n = 8). MAIN OUTCOME MEASURES Functional tests (FIM) and analytical tests (measurement of right eye movements by photo-oculography) at admission and after 3 months. RESULTS Results of the paired comparison tests showed (1) significant differences between the control group and the group with the half-eye patches for total FIM score (p = .01) and the displacements of the right eye in the left field (p = .02), and (2) no significant differences between the control group and the group with the right monocular patch. CONCLUSION Patching the right half-field helped subjects initially regain voluntary control over the deficit. The actual interpretation is based on physiologic and psychophysiologic models.

Health related quality of life and related factors in 539 persons with amputation of upper and lower limb

Purpose : Limb amputation is followed by an important rehabilitation process, especially when a prosthesis is involved. The objective of this study is to assess the nature of factors related to health related quality of life (HRQL) of persons with limb amputation. Method : The Nottingham Health Profile (NHP) treated 1011 subjects with major amputation of one or several limbs. Correlations were sought in multivariate regression model analyses between the six categories of distress explored by the NHP and age, sex, cause and level of amputation and rehabilitation programme. Results : Response rate was 53.3%. HRQL measured by the NHP was mostly impaired in the categories of physical disability, pain and energy level. Controlling for sex and age, young age at the time of amputation, traumatic origin and upper limb amputation were independently associated with better HRQL. Conclusion : It is concluded that HRQL is largely related to factors which are inherent to the patient and the amputation.

Influence of terrain on metabolic and temporal gait characteristics of unilateral transtibial amputees.

The difficulties confronted by amputees during overground walking are rarely investigated. In this study, we evaluated, in real-world situations, the influence of ground surface on walking in young, active amputees by measuring temporal and spatial gait parameters (free walking speed [FWS], step length [SL], step rate), energy expenditure (EE) (e.g., oxygen uptake, oxygen cost [O(2)C]), and Rating of Perceived Exertion (RPE). Ten active transtibial amputees and ten nondisabled control subjects walked at self-selected speeds on three types of ground surface (asphalt, mown lawn, and high grass). No significant differences were observed between the two groups on asphalt and mown lawn. Differences between nondisabled subjects and amputees occurred for FWS (p = 0.03) and O(2)C (p = 0.04) on asphalt and mown lawn and for all variables in high grass. When amputees (even though very active) were exposed to a particularly difficult environment, their FWS decreased (p = 0.008) and their EE and RPE increased (p = 0.005) compared with nondisabled subjects. In high grass, both groups reduced their self-selected speeds (-15% for control subjects and -16% for amputees). Control subjects reduced their velocity by reducing both SL (-8.7%) and cadence (-7.1%), whereas amputees reduced their velocity by reducing SL (-17%) only.

Effect on balance and gait secondary to removal of the second toe for digital reconstruction: 5-year follow-up.

Foot anatomy and lower limb function were analyzed in 11 children (aged 6.5–12.5 y) 5 years after removal of one or two second toes for digital reconstruction. In addition to physical examination and x-rays, postural balance and three-dimensional measurements of gait were analyzed. Among the 15 operated feet, five had bridle scars, three had claw deformities of the third toe, five had pain in the first intermetatarsal space, and seven had overt or early-stage hallux valgus (including five after unilateral toe removal). Hallux valgus deformation was also observed in three nonoperated feet. Maintenance of balance and rate of displacement of the center of pressure when standing on one foot with eyes closed were significantly altered for operated limbs compared with nonoperated limbs. Gait was rapid because of increased step cadence. Foot progression angle and ankle and knee joint sagittal kinematics during walking were normal. Although children appeared to not be affected in their daily life by the removal of the second toe(s), related foot anatomic and functional modifications require further follow-up.

Bursitis, adventitious bursa, localized soft-tissue inflammation, and bone marrow edema in tibial stumps: the contribution of magnetic resonance imaging to the diagnosis and management of mechanical stress complications.

OBJECTIVE To assess the contribution of magnetic resonance imaging (MRI) in the diagnosis of tibial stump bursitis, in the establishment of differential diagnosis, and in the therapeutic management prosthetic-stump interface, mainly by adaptation of the prosthetic device. DESIGN Two-year, prospective, consecutive series. SETTING University-affiliated prosthetic and rehabilitation center and university department of radiology. PARTICIPANTS A group of 17 persons with stump problems identified from a total of 139 consecutive below-knee amputees with prosthesis problems. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Clinical symptoms and MRI. RESULTS Clinical symptoms (variable stump volume, fluctuating mass at palpation with or without mechanical pain) were suggestive of bursitis in 10 patients. MRI confirmed bursitis in 9 and identified 1 in whom clinical signs suggested neuroma, giving an incidence of 10 of 139 amputees (7.2%). MRI identified 13 sites of bursitis (adventitious bursa, 11; synovial bursitis, 2) and 5 localized areas of soft tissue inflammation. MRI showed diffuse muscular edema at 1 site of clinically suspected bursitis, and bursitis at another site of suspected neuroma. Calcified bursitis was observed in 1 case. Bone abnormalities associated with bursitis (n=7) included osteophytes or fracture (n=4) or bone marrow edema (n=3). Two asymptomatic neuromas were also identified. MRI-guided modifications of the prosthetic interface led to favorable outcome in all cases. CONCLUSION Bursitis, adventitious bursae, and areas of localized soft-tissue inflammation are different aspects of the same disorder resulting from a mechanical conflict between the stump and the prosthesis socket. Besides contributing to diagnosis, MRI provides a precise assessment necessary for correcting the prosthesis-stump interface in a way that reduces mechanical stress and subsequently cures bursitis.

Violence to and maltreatment of people with disabilities: a short review.

OBJECTIVE Violence to disabled persons constitutes a major ethical problem. The European Academy of Rehabilitation Medicine has debated the matter; it presents this short report to alert a wider audience to the problem, with the aim of provoking debate and facilitating prevention. DESIGN The Academy has produced a full report on the literature. The present short report summarizes the essential features of this and significant references to violence. This is defined, types described, and risk factors and signs identified with the aim of informing rehabilitation practitioners. CONCLUSION Violence may take many forms, often being subtle, insidious and difficult to recognize. However, the members of the rehabilitation team may be able to provide significant help and act preventively as they work towards the better social integration of the disabled individual helping them gain more control of their lives. European legislation may help us in this task; we are reminded that our roles are set within the context of our civic duties of respect for and tolerance of all.

Mirror asomatognosia in right lesions stroke victims

The objectives of this prospective study were: to search for mirror-induced disorders of the body image in right hemisphere stroke victims using a description task of the contralateral upper limb, to analyze their clinical features, and to discuss possible mechanisms. Sixteen consecutive patients with documented unilateral right hemisphere stroke were examined for asomatognosia at the acute phase of stroke, then at least 2 months after stroke under three test conditions: without a mirror, with a conventional mirror, with an inverted mirror. Video recordings of the tests were analyzed to assess performance. The diagnosis of asomatognosia was retained if the subject reported at least one of three sensations: limb transformation, limb strangeness, and/or limb alienation. During the acute phase, 14/16 patients presented manifestations of asomatognosia. All of these spontaneous manifestations had disappeared 2 months later, but were reactivated in 12 patients when exposed to mirror images. The mirror tests revealed four situations: no disorder (n = 4), asomatognosia with both mirrors (n = 5), asomatognosia with the conventional or inverted mirrors (n = 1 and 5), and asomatognosia with the inverted mirror (n = 1). These manifestations were designated as mirror-asomatognosia, a disorder resulting from adaptations of the procedures leading to reorganization of the internal representations of the body image. These findings suggest there are several such internal representations of the body image and that direct body image and mirror body image would be two specific ones. These clinical manifestations and their evolution over time are an expression of the progressive nature of the underlying compensatory mechanisms made possible by brain plasticity.

Detection of visual field deficits and visual neglect with computerized light emitting diodes

A computer test for visual field deficits and visual neglect was developed and evaluated by testing 63 patients with brain damage. This computer test controls the sequence of unilateral or bilateral lights series, and stores the responses. Test results are compared to clinical and ophthalmological tests and neuropsychological assessment. Visual field deficits were present in 17 patients on the computerized test, in 16 patients on ophthalmological test, and in 13 patients on clinical examination. Neglect was present in 12 patients on the computerized test, and in 10 patients on the neuropsychological assessment. Eighteen patients had mixed disorder (hemianopia and neglect). Results of the chi 2 statistic confirm the greatest correlation between the computerized test and the ophthalmological (phi = 0.93; p < 0.001) and neuropsychological (phi = 0.90; p < 0.001) tests. Correlation between the computerized test and the clinical examination was poorer (phi = 0.85; p < 0.001). The computerized test makes it possible to detect mixed disorder with the same tool, during the same examination.

IRM et névromes des moignons dˈamputation des membres inférieurs

OBJECTIVE To describe RMI aspects of leg stump neuroma and to evaluate RMI scan interest for neuroma diagnosis and management. POPULATION AND METHOD During a 2 years period, 224 amputated patients consulting for pain or prostetics problems were studied. In 10 cases, a characteristic pain leads to neurona diagnosis. This is described as a sensation of ascending or descending electric shock induced by the stimulation of an identified point with a reproducible topography. In all these cases, RMI scans were performed. In thirty two other cases, a RMI scan was performed to confirm a pathology (bursitis, bone abnormality) or in order to establish an etiologic diagnosis. Twelve neuromas were diagnosed. RESULTS RMI scan showed a neuroma in the ten cases with a clinical suspicion and two asymptomatic neuromas were diagnosed out of the 32 patients without clinical suspicion. Medium delay between amputation and neuroma diagnosis is 11,6 year. In six cases, staking was modified and in six other cases, surgery was necessary. In aIl cases, clinical manifestations disappeared. Vanous RMI aspects ofneuromas are described and illustrated. Neuroma is observed on the extremity of a nerve that have a wavy aspect on its top. The neuroma is an oblong structure, with clear limits. There is an hyposignal with Ti sequence and variable signal with T2 and after gadolinium injection. DISCUSSION RMI scan is a good way to diagnose amputee neuroma. It makes it possible to demonstrate the pathological character of the neuroma. It has to be performed when a neuroma is suspected. It enables to confirm the diagnosis and establish the exact topography and anatomic connection. Mechanical strains role as a factor of discovering the neuroma is discussed because of the concomitant evolution of associated lesions (bursitis, bone edema). Surgical repair takes place after correcting abnormal mechanical strains.

Care protocol for persistent vegetative states (PVS) and minimally conscious state (MSC) in Lorraine: retrospective study over an 18-year period.

OBJECTIVES Retrospective analysis of the efficiency of a protocol for care of chronic vegetative states (CVS) and minimally conscious state (MCS) in Lorraine. MATERIAL AND METHOD Two indicators are used: protocol activity (number of patients hospitalized between 1988 and 2006, number of admissions per year, of requests per year, origin of requests, waiting time) and the epidemiological data (age, sex ratio, etiology, length of stay, geographic origin, number of deaths, number of hospital discharges). The number of CVS and MCS and patients having progressed towards arousal is specified as well as the technical procedures (orthopedic surgery, number of tracheotomies). RESULTS Forty-seven patients (30 males and 17 females) were hospitalized in a 12-bed unit. The number of admissions per year was 2.4, and the annual number of requests varied between five and 15. Hospitalization times ranged from six to 18 months. The average length of hospitalization was 41 months. Eighty-eight percent of the cases were residents of Lorraine. The etiology was traumatic (53%), vascular (38% including 12% anoxia), miscellaneous (9%). Fifteen percent rate of return to arousal (average time period: 28.41 months, traumatic etiology) with hospital discharge in four cases. CONCLUSION The protocol is managed as part of a local scheme and enables an appropriate response to a specific clinical profile by providing up-to-date multidiscipline follow-up care and a rapid solution should intercurrent events occur (signs of arousal, orthopedic deterioration, change of environment). Typical limitations are geographical remoteness and difficulties with family support care.
