Aim.
The general aim is to understand neurocognitive basis of Brain-Computer Interfaces (BCIs). We study the sensorimotor cortical activity of tetraplegic patients without any hand movements during attempted finger movements. We have earlier characterised such activity in able-bodied subjects performing finger movements.

Methods.
Eight tetraplegic patients have been studied in co-operation with Käpylä Rehabilitation Centre. Simultaneous whole-head MEG and EEG recordings were made at the Low Temperature Laboratory of Helsinki University of Technology. One of four visual stimuli instructed the subjects to attempt to lift either the left, right or both fingers, or not to attempt any movement. The stimuli were presented in random order every 3 seconds.

Results.
When the subjects did not attempt movements, 20-Hz MEG activity was suppressed bilaterally during attempted movement. The suppression was not followed by a contralaterally-dominant enhancement of the 20-Hz activity (“rebound”) as in able-bodied subjects.

Conclusions.
Our preliminary data show that the sensorimotor cortex of the paralysed patients responded to attempted movements of the paralysed limbs. Because of the lack of the strongly lateralized rebound, the separation of cortical correlate of the attempted left and right movement is not straightforward.

Introduction:
It is well known that the agreement of rehabilitation team and patients upon expected independence of the patients is of primary importance for the success of inpatient rehabilitation. Our hypothesis is that SCI patients will have a different preference for recovery of activity daily living and mobility outcome than that of the rehabilitation team.

Objective:

To compare SCI patients/rehabilitation team preferences for functional and walking outcome.

Participants and Methods:

Five SCI rehabilitation professional constituted the first panel and five complete SCI patients the second one. Consumer preference for walking was compared to the other motor functional domains of the Functional Independence Measure. Methods involved trading levels of independence (resources) across different items (features) utilising the Feature-Resource Trade-off Game developed by Steinman.

Results:

Patients moved first wheelchair autonomy and only later walking; this was not a consequence of the distance from the lesion, since most patients had a distance of less than four months. On the contrary professionals moved walking early during the game. Bowel and bladder autonomy was comparable in the two groups.

Conclusion:

Differences in consumer and clinician preferences emphasize the importance of establishing consumer oriented goals.

Main institution where the work was done: Combined Neurosurgical and Orthopaedic Spine Program, Vancouver Hospital and Health Sciences Centre, BC, Canada

Design:
Retrospective cohort with cross-sectional follow-up.

Objectives:

  • Primary: determine motor recovery in patients with CSCI.
  • Secondary: determine factors predicting local recovery; assess outcome (Functional Independence Measure (FIM), Short Form-36 (SF-36)).

Background:
Motor recovery following CSCI has been described. The definition has evolved, spinal shock is often not addressed, and few studies differentiate between local and caudal neurologic recovery.

Methods:
Patients admitted with CSCI between 1994 and 2000 had initial and follow up ASIA motor scores. Patients were excluded if incomplete following resolution of spinal shock. Minimum two-year follow-up consisted of an ASIA motor score (AMS), FIM and the SF-36. Changes were evaluated using the Wilcoxon two-sample test.

Results:
Of 133 patients, 94 were eligible and 70 completed follow-up. For tetraplegics (N=30) the average admission AMS was 12 and 20 at follow-up, reflecting local recovery only; for paraplegics (N=41) the scores were 49 and 52. In the tetraplegic group, 67% showed recovery 1 level, 16% 2 levels, and 3% 3 levels below the injury level, age and energy of injury predicting local recovery. SF 36 scores are presented.

Conclusions:
Motor recovery does not occur below the zone of injury for patients with CSCI. Varying degrees of local recovery can be expected in individuals with tetraplegia.

Aim:
To look at prevalence, change over time and effects of pain in a sample of people with long standing spinal cord injury (SCI).

Method:
373 participants from UK, USA and Canada were interviewed in the 2002 follow-up of the International Study of Ageing with SCI.

Results:

The sample was 85% male, mean age was 58.7 and mean duration of injury 35.9 years. 35.5% were tetraplegic, 43.7% paraplegic and 20.8% incomplete. Pain was reported by 327 participants (87.7%). The most common types of painref were secondary, mechanical and deafferentation. Pain negatively affected all activities of daily life, life satisfaction, quality of life and depression. Management strategies included medication (55.6%), lifestyle changes (21.9%), technical adaptations (21.3%), coping (17.4%) and alternative therapies (12.8%). Younger participants, females and Canadians reported higher levels of pain, greater negative impact on daily life and more use of management strategies, while older participants more frequently reported increasing levels of pain. Level of injury did not influence any of the above.

Conclusions:
Pain is an issue in majority of patients with long standing SCI, tends to increase over time and has a negative effect on daily life, life satisfaction, quality of life and depression.

Introduction:
Upright posture confers numerous medical and social benefits to a spinal cord injured (SCI) patient. However, doing so is limited in many (particularly if a high lesion and complete) by symptoms of orthostatic hypotension (OH). Amongst these patients, rehabilitation can be prolonged and social integration may be more difficult.

Objective:
Ascertain the number of spinal cord injured patients reluctant to try the standing frame or wheelchair because of their fear of OH symptoms. Also, determine the proportion of standing apparatus users in which symptomatic OH has restricted their use.

Method:
Population-based survey conducted by Internet-accessible electronic questionnaire.

Results:
293 respondents. Mean age 44.6; 76% male. Median time from injury: 7 years. 38% suffered with OH; majority were complete injuries and all (except one – T12) were T5 or above level. 52% replied that were using standing wheelchairs or frames. Of these, 59 (20% of total) stated that OH symptoms were limiting the use of their upright apparatus. Of those who did not use standing wheelchairs or frames, 16 (5.5% of total) reported that this was because of the fear of worsening their OH.

Conclusion:
OH restricts standing apparatus use in a significant proportion (a total of 25.5% of respondents in this survey) of SCI patients. New treatments that offer control of blood pressure when becoming upright are needed.

The legal system in Israel differentiates between four groups of disabled people: Defense Ministry insured – DMI, Work Accident Disability – WAD, Car Accident Disability – CAD, and Non Specified Disabled – NSD.Despite the fact that the disabled are entitled to the same medical and rehabilitation services, differences between these four groups can already be seen in the early stages of hospitalization.

The purpose of the paper is to study the impact of these differences on the paraplegics’ quality of life.

There were 82 paraplegics: 24 DMI, 21 WAD, 19 NSD, 18 CAD. Age range: 18-55. Treatment completed at least five years prior to the research. Five questionnaires were used: the SCI QU-23, the SCL-90, the Psycho-Social Adaptation to Illness, the World Assumption Scale and a life situation questionnaire.

The DMI and NSD had less hospitalizations and problems regarding employment when compared with CAD and WAD. The NSD and WAD reported a better family situation and a better perception of their social life. The NSD and the WAD reported fewer signs of psychiatric stress compared with CADNo significant differences were found in signs of mental stress between the NSD and others. No differences were found in life assumptions in the four groups.

INTRODUCTION
Outcomes of neuro-urological management of paediatric spinal cord injury (SCI) patients.

PATIENTS AND METHODS

Ten SCI patients (2 cervical, 7 thoracic, 1 lumbar), six males, four females, mean age at injury, 13.6 years (6 complete / 4 incomplete), followed, for mean period of 13.1 years. Three diagnostic subgroups - neurogenic detrusor overactivity (NDO), acontractile detrusor and low compliance. Complications and operative procedures noted.

RESULTS
In NDO, (n=6) initial management, supra pubic catheterisation (SPC), (n=1), condom drainage (n=2), urge voiding (n=2) and self-intermittent catheterisation (SIC), (n=1) changed to, ileal conduit (n=1), SARSI (n=1), SIC (n=3) and urge voiding (n=1). Complications were reflux, kidney scarring with decreased GFR, hydronephrosis, kidney and bladder stones and small capacity bladder. Operations included, ileal conduit , sacral anterior root stimulator implant (SARSI), sphincterotomy with stent, STING, Cystolitholapaxy. In acontractile detrusor, (n=2), management was SIC and complications were small noncompliant bladder, stress incontinence. Operations, Mitrofanoff and clam ileocystoplasty. In low compliance, (n=2) management included SIC and urge voiding with SIC. Complications were urethro-perineal fistula, kidney stone.

CONCLUSION

Bladder management in paediatric SCI is dependent on level of injury and changing bladder neurology. Complications are avoided by regular follow up and management based on up to date investigations

Objectives:
1) Assess reliability of motor and sensory examination of the International Standards for Classification of Spinal Cord Injury (SCI),
2) Assess differences in reliability between physician and physical therapist examiners.

Methods:

Sixteen examiners (8 physicians, 8 physical therapists), with a minimum of two years clinical SCI experience, examined three in a pool of 16 SCI patients. The study was done in preparation for Proneuron’s Phase II autologous incubated macrophage study for treatment of acute SCI patients. Inter-rater reliabilities were assessed using intraclass correlations (Model 1).

Results:
The intraclass correlations were high: 0.97 for motor scores; 0.96 for light touch scores; and 0.88 for pinprick scores. Computing individual examiner intraclass reliabilities (across three patients) we obtained coefficients of 0.91-1.00 for motor; 0.62-1.00 for light touch; and 0.56-0.99 for pin prick. Differences between physicians and physical therapists were non-significant. The correlation between light touch and pin prick reliabilities was 0.70 (p = 0.003).

Conclusions:
1) The scales are generally reliable, exceeding normally recommended reliability values, and appropriate for clinical trials, 2) The few low examiner reliabilities observed are not attributable to professional training (physician versus physical therapist), 3) Examiners who were reliable on light touch tended to be reliable on pin prick and vice versa.

Name of ISCoS Member (Author): Linda Jones, PT, MS (membership to be submitted)
Main institution where the work was done: Kessler Institute for Rehabilitation, West Orange, NJ

Background:
Despite its widespread use, the accuracy of the AIS (American Spinal Injury Association Impairment Scale) classification of spinal cord injury (SCI) using the 2002 International Standards for Neurological Classification (the Standards) has not been evaluated.

Methods:

Eight physicians attending an investigators meeting for the Proneuron Phase II autologous incubated macrophage study for treatment of SCI Patients participated in a study of AIS grade reliability. Each physician determined AIS grade on 15 sample cases. For each of these cases, an expert analyst’s AIS grade was used as the comparison standard.

Results:

Overall Kappa for agreement between physicians and the expert opinion was 0.685 (p < 0.001). Individual physician Kappas ranged between 0.444 and 0.907. The overall proportion of correct responses across physicians and cases was 77.5%. However, accuracy varied by true patient grade: 97.5%, 66.7%, 67.5%, 68.7% for Grades A, B, C, and D respectively (p = 0.003). Agreement for Grade A cases was higher than that for other Grades (p < 0.05), which did not differ significantly among themselves.

Conclusions:
1) The reliability of the AIS, as measured by Kappa, is reasonable on average but should be improved. 2) Reliability training should focus on Grades B, C and D, as physicians already demonstrate high accuracy in determining Grade A.
