Abstract
The prevalence of obesity among the population is increasing, including in many elderly people. The purpose of this study was to evaluate whether lumbar spinal surgery in elderly patients with different body mass indices influences pain, satisfaction rate, and activities of daily living. Two hundred ninety-eight elderly patients (older than 65 years), 153 women and 145 men, who had decompressive laminectomy, discectomy, or combinations of these procedures during 1990 to 2000 were followed up. Indications for surgery included limitation in doing activities of daily living, severe pain, or both. The patients were classified into one of four categories in terms of their body mass index. The operative parameters, pain reduction, satisfaction rate, and activities of daily living using the Barthel index were assessed. The more obese patients were younger, tended to be female, and were more symptomatic. All four groups of patients had reduction in pain, improvement in activities of daily living, and were satisfied with the operation. Our data suggest that it is reasonable to operate on patients who are elderly and obese and who have lumbar symptoms, with the appropriate indications.

Abstract
BACKGROUND Little information is available about the survival, neurological recovery, and length of stay in hospital for rehabilitation (LOS) of patients with spinal neurological deficit following disc herniation (DH). STUDY DESIGN Retrospective cohort study. OBJECTIVE To report on outcomes and factors affecting these. SETTING The Spinal Research Laboratory, Loewenstein Rehabilitation Hospital, Israel. SUBJECTS A total of 158 patients with DH spinal neurological lesions (DHSNL). METHOD Data were collected retrospectively. Survival was assessed using the Kaplan-Meier method; relative mortality risk by the Cox proportional hazard model. Neurological recovery was evaluated by calculating the change in Frankel grades, and factors that affect it were assessed by logistic regression. LOS associations were analyzed with ANOVA. RESULTS The median age at lesion onset was 48 years, and the median survival 29 years. Age and gender had a significant effect on survival, but not so lesion severity, level, or decade of onset. Of the 69 patients who had Frankel grades A, B, or C on admission, 72% achieved useful recovery to grades D or E. The severity and level of the spinal neurological lesion (SNL) had a significant effect on recovery. The mean LOS was 87 days; it was significantly affected by lesion severity and level and by the decade of admission to rehabilitation, and decreased with time. CONCLUSIONS Patients with DHSNL who were admitted for rehabilitation have favorable survival and recovery rates compared with previously studied patients with other types of SNL. Their LOS is probably a function of medical requirements, but is decreasing with time.

Abstract
STUDY DESIGN Intercostal nerve to spinal nerve root anastomosis in chronic spine-injured patients. OBJECTIVES To analyze the effectiveness of neurogenic bladder reinnervation in spinal cord-injured patients through artificial creation of sprouting (intercostal nerve to spinal nerve root anastomosis). SETTING Center of Neurosurgery, Moscow, Russia. Operations were performed by Professor A Livshits. (At present, Professor A Livshits is working at the Spinal Care Unit, Meir General Hospital, Kfar Saba, Israel.) METHODS A total of 11 patients with spinal cord injury of the L1 level were operated on in the late (chronic) stage. The neurological status and urodynamics were investigated before and 12 months after operation. A laminectomy from T11 to L3 was performed. Next, a neurolysis of the 11th and 12th intercostal nerves was carried out, at a distance of 20-21 cm, and transferred to the vertebral canal. The S2-S3 roots were then cut in their proximal portion and anastomosed end-to-end to the intercostal nerves. The results of urodynamic studies were calculated by the Wilcoxon signed rank test for comparison before and 12 months after operation. RESULTS OF URODYNAMIC STUDIES: Bladder capacity (ml) before operation - 489+/-79, after operation - 350+/-39, urine volume (ml) before - 18.2+/-17, after - 306.4+/-39.8, residual urine (ml) before - 459+/-99.4, after - 50+/-11.8. Detrusor tone (rel. units) before - 0.6+/-1.5, after 1.2+/-0.2; voiding pressure (cmH(2)O) before - 4.4+/-5.2, after - 30.5+/-4.9. Force of detrusor contraction before - 5+/-5.8, after - 32.8+/-5.5. Sphincter resistance (cmH(2)O) before - 6.5+/-3.8, after - 21.1+/-4.2. Significant improvements in bladder function were observed during the 10th to 12th postoperative months. Restoration of reflex voiding occurred in all patients; in eight of the 11 paresthesic in the groin and scrotum and reappearance of the bulbocavernous, anal and cremasteric reflexes were noted. CONCLUSION These results suggest that a restitutive process occurs in the bladder under novel conditions of its nerve supply provided by the intercostal nerve and by new connections established between it and the bladder nerves. Spinal cord lesions that might benefit from nerve crossover surgery would be located at the conus, so functional intercostal nerves could be connected to sacral roots to bypass the injury in an attempt to restore central connections to the bladder.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To monitor length of stay (LOS) in a specialist spinal cord lesion (SCL) department in Israel, evaluate factors that affect it, and assess its association with other outcome measures. SETTING Loewenstein Rehabilitation Hospital, Raanana, Israel. METHODS In all, 1367 SCL patients treated between 1962 and 2000, and a group of 44 patients admitted between 1996 and 2002 were recruited. LOS, factors that affect it, and Spinal Cord Independence Measure second version (SCIM-II) gain and efficiency were measured. Data were collected from hospital charts and from the Population Registry of the Israel Ministry of Internal Affairs. LOS associations were analyzed with ANOVA, ANCOVA, Pearson's chi(2) test, Pearson's correlation, and Cox proportional hazard model. RESULTS The mean LOS was 239 days for traumatic SCL (SD=168) and 106 days for non-traumatic SCL (SD=137). SCL etiology, SCL severity, and decade of admission to rehabilitation, were associated with the LOS (P<0.001). SCIM II gain correlated with LOS in the first 70 days after admission (r=0.81-0.82; P<0.001). In some patients, longer LOS was associated with a considerable increase in ability, through 5-8 months from admission. CONCLUSIONS LOS of patients with SCL in Israel is within the customary LOS range in Europe. Longer LOS in a specialist SCL department may be positively associated with improved rehabilitation outcome. Further study is required to determine the LOS that allows optimal achievements.

Abstract
Radiofrequency (RF) ablation is a method that has been gaining popularity over the past few years among spinal surgeons. It has a role when dealing with pain of spinal origin, either mechanical or neuropathic, after conservative treatment has failed. In the present study, 122 patients with a minimal follow up of 1 year were examined at our institution after having undergone RF heat lesion of the medial branch for mechanical spinal pain (low back pain, thoracic pain or cervical pain). They were followed up 1, 3, 6 and 12 months after treatment. Twenty-two of them were additionally followed up at 18 months. After 1 month, 91 patients (75%) were satisfied with the results. After 3 months, 87 patients (71%) had significant pain relief, while in 35 patients (29%) there was no improvement. After 6 months of follow-up, 80 patients (66%) had pain relief and in 42 patients (34%) there was no effect. At 12-months follow-up, 77 patients (63%) showed good results and 45 patients (37%) had no effect. In the case of the 22 patients who were followed for 18 months, all showed significant pain relief. Minor complications occurred in 27 patients (22%), who had transient discomfort and burning pain. We concluded that RF is a safe and partially effective procedure for mechanical back pain.

Abstract
Complications of the donor site after the harvest of corticocancellous bone graft from the posterior iliac crest are very common. The most common are chronic donor site pain, tenderness, and sensory disturbances. This study investigates the results of the midline, lumbar fascia splitting approach for harvesting bone graft in lower lumbar spine fusion and compares them with the classic separate incision approach. A retrospective study of 107 patients compares two groups. The first group of 56 patients (35 males and 21 females with an average age of 41.8 years) had bone graft taken by splitting the two layers of the lumbar fascia down to their attachment to the iliac crest. The second group of 51 patients (29 males and 22 females with an average age of 43.7 years) had a separate incision over the iliac crest. In the first group, 82.1% had no tenderness, 8.9% mild, 7.1% moderate, and only 1.8% severe tenderness over the donor site. In the second group, 45.1% had no tenderness, 21.6% mild, 17.6% moderate, and 15.7% severe tenderness over the donor site. Five patients of the separate incision group (9.8%) had a lump in the donor site compared with none in the "same incision" group. Sensory disturbances over the donor site were found in 5.4% of the first group and in 21.6% of the second group. Harvesting bone graft from the posterior iliac crest for lower lumbar spine fusion through a midline, fascia splitting approach was found superior to the traditional, separate incision approach.

Abstract
BACKGROUND Survival following spinal cord injury (SCI) has greatly improved since the unsuccessful attempts to repair the damaged spinal cord were replaced by systematic prevention and treatment of complications caused by the neural damage. OBJECTIVE To evaluate the main outcome measures in patients with spinal cord injury. DESIGN Retrospective cohort study. SETTING Loewenstein Rehabilitation Hospital, the major referral center for rehabilitation medicine for hospitals throughout Israel. SUBJECTS 250 consecutive patients, injured between 1959 and 1992. MAIN OUTCOME MEASURES Survival rates and mortality risk factors. METHOD Demographic, clinical, and mortality data were collected from the hospital charts and from the Population Registry of the Israel Ministry of Internal Affairs. Survival rates were estimated using the product limit (Kaplan-Meyer) method, and their association with known risk factors was analyzed with the Cox proportional hazard model. RESULTS The survival rate after injury was 81% after 10 years, 75% after 20 years, and 62% after 30 years, and 50% after about 36.5 years. Survival was found to be negatively associated with age (P=0.01) and with high spinal level of injury (P=0.003). CONCLUSIONS Survival rates in the studied population are similar to those reported in other countries, and are close to those of the general population living in Israel in the same time period. The study demonstrates that developing countries can reach survival rates comparable to those of developed countries, and may contribute to better survival predictions of patients with SCI.

Abstract
BACKGROUND The Spinal Cord Independence Measure (SCIM) is a new disability scale developed specifically for patients with spinal cord lesions (SCL). Its original and second versions (SCIM and SCIM II) were found to be reliable and more sensitive than the Functional Independence Measure (FIM) to functional changes in SCL patients. OBJECTIVE To further validate the SCIM II, examining its components on a larger population. DESIGN Retrospective cohort study. SETTING Two rehabilitation centers in Israel. SUBJECTS Two hundred and two inpatients with SCL. INTERVENTIONS Routine SCIM assessments by staff nurses. Rasch and accompanying analyses. MAIN OUTCOME MEASURES Unidimensionality of subscales (areas of function); goodness of fit of the tasks to the Rasch model; relationship of total-patient and single-task performance-ability; usability of task categories and the order of threshold locations between them; subscale discrimination of ability and difficulty and hierarchical nature; discrimination of task-categories ability, ie, distribution of thresholds along ability levels; and differential task behavior by age, gender and examination subgroups. RESULTS Four unidimensional subscales were identified, and an acceptable goodness of fit to the Rasch model was demonstrated in most of their tasks (infit mean square=0.8-1.2, outfit mean square=0.6-1.4). However, some tasks showed overfit (bathing lower body) and some showed misfit (wheelchair-car transfer). Additional analyses performed to check for reasons for less than acceptable fit revealed flaws in a minority of the outcome measures. CONCLUSIONS The findings of this analysis confirm the validity and reliability of the SCIM II. To a large extent we can infer that the SCIM II construct allows for the detection of any level of disability in any patient with SCL. A few item categories, however, should be rephrased or removed.

Abstract
PURPOSE To examine the suitability of the revised Spinal Cord Independence Measure, the Catz-ltzkovich SCIM, for evaluation of patients with spinal cord lesions, as compared to the original SCIM and to the Functional Independence Measure (FIM). METHOD The revised SCIM was applied by paired independent teams of occupational therapists, physiotherapists and nurses and the FIM by a single nurse. The examiners assigned scores to the functional capabilities of 28 patients with spinal cord lesions. The scores by the revised SCIM were analysed for reproducibility as between the two teams of examiners (interrater reliability) and for their correlation with the FIM scores. RESULTS The frequency of identical scoring by two independent examiners (total agreement) was 80% or higher for 13/18 individual functions listed in the revised SCIM. In the self-care category it was 80-99%, as compared to 75-87% before revision. In neither bowel management nor bed mobility was there an increase over the original SCIM in the frequency of identical scores, despite rephrasing and restructuring of the scoring criteria. A high correlation was noted between the paired scores for all functions listed as well as for those comprising each of the four functional categories (r = 0.90-0.96, p <0.001). The total revised-SCIM scores were significantly correlated with those derived by the FIM (r = 0.835, p < 0.001). CONCLUSIONS The findings indicate that the newly revised SCIM (Catz-Itzkovich) is a valid and highly reproducible measure of daily function in patients with spinal cord lesions, and is superior to the original SCIM. We recommend that it supersede the original SCIM.

Abstract
PURPOSE/METHOD SPIM Spinal Pain Independence Measure. a new disability scale designed for patients with chronic low back pain disability, has been developed and studied at the Spinal Department of Loewenstein Rehabilitation Hospital. The SPIM differs from other existing scales for evaluation of chronic back disability, in that it is designated particularly for patients with deficits in primary ADL and evaluates function by observation. RESULTS/CONCLUSIONS This study shows the SPIM to be reliable: it supports the validity of the scale and points out a possible advantage of the SPIM over existing scales in sensitivity to functional change of patients with prominent disability. Further elaboration and examination of the SPIM is still needed.

Abstract
BACKGROUND The spinal cord independence measure (SCIM) is a newly developed disability scale specific to patients with spinal cord lesions (SCL). Its sensitivity to functional changes in a whole cohort of SCL patients was found to be better than that of the functional independence measure (FIM). OBJECTIVE o compare the sensitivity to functional changes of the SCIM and the FIM in SCL subgroups. DESIGN A comparative self-controlled study. SETTING The Spinal Department, Loewenstein Rehabilitation Hospital, Raanana, Israel. SUBJECTS 22 SCL inpatients. INTERVENTIONS Monthly SCIM and FIM assessments of the subgroups. MAIN OUTCOME MEASURES Functional change detection rate (FDR) and mean differences between consecutive scores (DCS). RESULTS The outcome measures of the SCIM were higher than those of the FIM for tetraplegia and paraplegia, complete and incomplete lesions (the FIM missed 25-27% of the functional changes detected by the SCIM; DSC 8.2-11.4 vs 5.2-9; P<0.05 in most comparisons). The SCIM did not exhibit this advantage, however, in the functional areas of self-care and mobility in the room and toilet. Further subgrouping yielded similar results. CONCLUSIONS The SCIM is more sensitive than the FIM to functional changes in the subgroups studied, and has the potential to serve as a universal tool for disability assessment of SCL patients.

Abstract
Therapeutic injection of botulin toxin is well-recognized for reducing tonus in local dystonia. However, its efficacy in reducing spasticity in spinal cord injuries is still unproven. 4 men and 1 woman (mean age 39 years, range 20-56) with spinal cord injury and debilitating spasticity, and no response to standard treatment for spasticity received injections of botulin, 200-300 U, into 4-8 points in their legs to block muscle-nerve synapses. In all 5 tonus was reduced in the area of the block, while in some it was also reduced in more distal muscles. In 1 there was reduced tonus in both the injected and contralateral leg. The therapeutic effect on tonus persisted for 3 months. In spite of objective improvement in tonus in all 5, only 3 felt subjective improvement, but in none was there improvement on standard functional scaling. We found injection of botulin toxin effective in reducing tonus in the spinal cord-injured, and to some extent in improving subjective feeling of well-being in some of them. Objective measurement might show functional improvement after larger doses of toxin injected into more muscles. This might be necessary because the muscle mass of the legs is large and the intensity of involuntary contraction is especially high in these patients.

Abstract
PURPOSE The aim of the present study was to compare the functional effect of conservative and surgical treatment in post-traumatic syringomyelia. METHOD The files of 10 male patients treated for posttraumatic syringomyelia were retrospectively reviewed from 1986 to 1996. RESULTS The spinal lesion was complete in five patients and incomplete in five. All patients underwent rehabilitation, five of them following surgery. The operative procedures included drainage by syringosubarachnoid shunting (four patients) and decompressive laminectomy (one patient). Rehabilitation alone improved the functional status in all five patients so treated. After surgery, function deteriorated in four of the five operated patients, and rehabilitation failed to restore the preoperative functional status in any of them. CONCLUSION In view of the results it is suggested that patients with post-traumatic syringomyelia undergo rehabilitation with very close clinical and magnetic resonance imaging follow-up.

Abstract
OBJECTIVE To evaluate the feasibility of a computerized mattress system based on a novel concept in sore prevention: continuous monitoring and adjustment of the interface pressure in small segments of contact between the skin and the supporting surface. DESIGN A preliminary observational study. SETTING The Spinal Department, Loewenstein Rehabilitation Hospital, Raanana, Israel. SUBJECTS Twelve patients with spinal cord lesions. INTERVENTIONS Patients were examined for signs of impending sores after lying on the mattress for up to 4 successive hours. The pressure within each of the mattress's air cells was continuously measured and adjusted. RESULTS No evidence of redness or excessive perspiration was found in any of the areas considered to be high risk for bed sores. Maximal interface pressure was 22-30 mm Hg in most of the examinations. Most of the patients felt comfortable on the mattress and the staff adapted easily to its operation. CONCLUSIONS The system is apparently safe, and at least as efficient as other existing means for preventing sores. In addition, it may allow for increased intervals between bed positionings. We conclude that this approach of pressure control has the potential to improve bed sore prevention in a rehabilitation hospital setting.

Abstract
The Spinal Cord Independence Measure (SCIM) is a new disability scale developed specifically for patients with spinal cord lesions in order to make the functional assessments of patients with paraplegia or tetraplegia more sensitive to changes. The SCIM includes the following areas of function: self-care (subscore (0-20), respiration and sphincter management (0-40) and mobility (0-40). Each area is scored according to its proportional weight in these patients' general activity. The final score ranges from 0 to 100. This study was performed to evaluate the reliability of the SCIM and its sensitivity to functional changes in spinal cord lesion patients compared with the Functional Independence Measure (FIM). Thirty patients were included. Scores were recorded one week after admission and thereafter every month during hospitalization. Each area of function was assessed by a pair of staff members from the relevant discipline. The comparison of scores between each pair of rates revealed a remarkable consistency (r = 0.91-0.99; P < 0.0001; slope approximately 1; constant approximately 0). The total SCIM score (mean = 51, SD = 21) was lower than the total FIM score (mean = 87, SD = 23) owing to the difference in scale range structure and the relatively high cognitive scores of our patients; however, a relationship was noted between the scores of both scales (r = 0.85, P < 0.01). The SCIM was more sensitive than the FIM to changes in function of spinal cord lesion patients: the SCIM detected all the functional changes detected by the FIM total scoring, but the FIM missed 26% of the changes detected by the SCIM total scoring. The mean difference between consecutive scores was higher for the SCIM (P < 0.01). We conclude that the SCIM is a reliable disability scale and is more sensitive to changes in function in spinal cord lesion patients than the FIM. The SCIM when administered by a multidisciplinary team, may be a useful instrument for assessing changes in everyday performance in patients with spinal cord lesion.

Abstract
For the last three decades external sphincterotomy has been well accepted as a treatment for bladder outlet obstruction in patients with a spinal cord lesions. Recently, however, its value has been brought into question. To assess the current place of this procedure in the treatment of the neuropathic bladder of spinal origin, we studied the outcomes of sphincterotomy in 32 patients. Post-voiding residual urine volume decreased after surgery in 27 patients (84%), considerably in 22 (69%) of them. Clinical infection resolved in 14 out of 19 patients (74%), hydronephrosis disappeared in two out of three (66%), and vesicourethral reflux improved in three out of five (60%) and was cured in two (40%). Six of the patients (19%) were freed from catheterization, but two patients (6%) lost partial continence. Sphincterotomy is an important tool in the treatment of spinal patients with bladder outlet obstruction and should be considered when the proper indications exist.

Abstract
Saccadic characteristics were examined in 15 patients with unilateral hemispheric stroke. Eye movements were measured by a standard electro-oculogram technique. In patients with cortical infarcts, mean gain values were lower than in the control subjects for eye movements directed away from the infarct (contralateral), but higher for eye movements towards the infarct (ipsilateral) (p < 0.025). We suggest that impairment of efferent neural signals from the affected hemisphere of stroke patients may decrease excitation of the contralateral neural circuits and inhibition of the ipsilateral neural circuits of the brainstem saccade generator.

Abstract
Patients with hemispheric lesions frequently suffer from equilibrium impairment that may be prolonged and may interfere with rehabilitation. In an effort to clarify whether this phenomenon is related to vestibular dysfunction, we examined the relationship of the horizontal vestibulo-ocular reflex (VOR) with stability in 15 patients with unilateral hemispheric stroke. The study included electro-oculographic recording of the VOR while the patients were rotated in a vestibular chair. Stability was scored in accordance with the patients' ability to maintain equilibrium in six graded positions. The findings demonstrated relationship between VOR gain (eye/head displacement) and equilibrium. It is suggested that the "loss of balance" after stroke may be related to an impairment of the corticovestibular modulation of the vestibular function.

Abstract
This study examined vestibular function following hemispheric ischemic strokes, by testing the suppression of the vestibulo-ocular reflex (VOR). Fifteen patients with cortical or subcortical infarcts several months after a unilateral hemispheric stroke were compared with control subjects. The results indicated impairment of VOR suppression in patients with cortical infarcts. It is suggested that cortical infarcts may induce a mild and symmetrical impairment of vestibular activity which may be responsible for mild and transient imbalance in patients who undergo stroke.

Abstract
Papilledema, is a known complication of various spinal pathologies. It has, however, been only infrequently reported following spinal injury, and may be overlooked in these cases. Presented herein is a 27 year old male who suffered thoracic and lumbar spinal injuries. Papilledema following mild increase in intracranial pressure (IICP) developed 3 weeks following trauma, and subsided within 8 weeks. The importance of routine repeat ophthalmoscopic examinations following spinal injury to detect changes characteristic of IICP is emphasized.

Abstract
A new device for elbow extension, developed as a dynamic orthosis and also as a static splint for a C5 tetraplegic arm, is presented. A patient with tetraplegia, probably related to infection of the central and peripheral nervous system, had a paralysed right triceps muscle, with a very strong corresponding biceps. Extension by force of a posterior stretched rubber ring made the arm useful, while the possibility to lock the elbow hinges of the orthosis at any desired angle enabled static splinting of the elbow to increase the range of motion.
