A preliminary study on the relationship between proprioceptive deficits and motor functions in chronic stroke patients.

Although motor and sensory impairments of the upper limb after stroke have been widely studied, the relationship between sensory deficits and motor functions has been less thoroughly explored. In this ongoing study, we investigated the relationship between proprioceptive impairments and motor functions with 20 chronic stroke survivors. Their proprioceptive abilities were assessed with a passive joint position matching test using H-Man and their motor functions were assessed with ARAT (Action Research Arm Test) and FMA (Fugl Meyer Upper Extremity Assessment) clinical scores. The assessments were conducted before, during and after the therapy. Results indicated a significant difference between the proprioceptive outcomes of healthy and stroke participants (at baseline) in both matching accuracy (absolute error, p=0.02) and precision (variability of the signed error, p=0.03). Significant correlations were found between the proprioceptive assessment outcomes (assessed before the beginning of the motor rehabilitation) of stroke participants with impaired proprioception and their ARAT clinical scores assessed at the first follow-up (week 12) (rho =- 0.74 and p=0.047 for the absolute error; rho =-0.78 and p= 0.03 for the variability of the signed error). The results from this preliminary study indicated a significant relationship between proprioceptive impairments and motor function performances in proprioceptively impaired chronic stroke participants.

Factors associated with delayed discharges after inpatient stroke rehabilitation in Singapore

<p><b>INTRODUCTION</b>This study determines the extent of, and factors associated with, delayed discharges for stroke patients from inpatient rehabilitation.</p><p><b>MATERIALS AND METHODS</b>A retrospective cohort study utilising medical notes review was conducted at an inpatient rehabilitation centre in Singapore. Acute stroke patients (n = 487) admitted between March 2005 and December 2006 were studied. The primary measure was delayed discharge defined as an extension in inpatient stay beyond the planned duration. Factors associated with delays in discharge were categorised as individual, caregiver, medical and organisational.</p><p><b>RESULTS</b>There were a total of 172 delayed discharges (35.6%). The mean [standard deviation (SD)] length of stay was 40.5 days (SD, 19.5 days) and 25.8 days (SD, 11.4 days) for patients with delayed and prompt discharges, respectively. Mean extension of stay was 9.7 days (SD, 13.8 days). Caregiver-related reasons were cited for 79.7% of the delays whereas organisational factors (awaiting nursing home placement, investigations or specialist appointments) accounted for 17.4%. Four factors were found to be independently associated with delayed discharge: discharge to the care of foreign domestic helper, nursing home placement, lower admission Functional Independence Measure (FIM) motor score and discharge planning process.</p><p><b>CONCLUSIONS</b>Our study suggests that caregiver and organisational factors were main contributors of delayed discharge. Targeted caregiver training and the provision of post-discharge support may improve the confidence of caregivers of patients with greater motor disability. The use of structured discharge planning programmes may improve the efficiency of the rehabilitation service. To reduce delays, problems with the supply of formal and informal post-discharge care must also be addressed.</p>

A brief review of traumatic brain injury rehabilitation

<p><b>INTRODUCTION</b>This article aims to provide an overview of the epidemiology, medical and rehabilitation issues, current evidence for traumatic brain injury (TBI) rehabilitation, recent advances and emerging practices. Special TBI population groups will also be addressed.</p><p><b>MATERIALS AND METHODS</b>We included publications indexed in Medline and the Cochrane Database of Systemic Reviews from 1974 to 2006, relevant chapters in major rehabilitation texts and Physical Medicine and Rehabilitation Clinics of North America and accessed Internet publications.</p><p><b>RESULTS</b>TBI has been implicated by the World Health Organisation to be a 21st century epidemic similar to malaria and HIV/AIDS, not restricted to the developed world. One third of patients may suffer severe TBI with long-term cognitive and behavioural disabilities. Injuries to the brain do not only damage the cerebrum but may give rise to a multisystem disorder due to associated injuries in 20% of cases, which can include complex neurological impairments, neuroendocrine and neuromedical complications. There is promising evidence of improved outcome and functional benefits with early induction into a transdisciplinary brain injury rehabilitation programme. However, TBI research is fraught with difficulties because of an intrinsically heterogeneous population due to age, injury severity and type, functional outcome measures and small samples. Recent advances in TBI rehabilitation include task-specific training of cognitive deficits, computer-aided cognitive remediation and visual-spatial and visual scanning techniques and body weight-supported treadmill training for motor deficits. In addition, special rehabilitation issues for mild TBI, TBI-related vegetative states, elderly and young TBI, ethical issues and local data will also be discussed.</p>
