    ABSTRACT: Objectives: To investigate the long-term effects of the toe spreader on gait characteristics, pain, activity level and balance in individuals with chronic stroke who exhibited tonic toe flexion reflex. The secondary objectives were to determine the sample size for future studies and to assess compliance to the use of the toe spreader.Design: Single-blind, randomized controlled pilot trial.Setting: Outpatient clinic of a tertiary hospital in Singapore.Subjects: Nine ambulatory participants with tonic toe flexion reflex more than six months post stroke.Intervention: Control or customized toe spreader groups for six months. The toe spreader was made of Rolyan Ezemix elastomer putty and worn with sport sandals during ambulation.Main measures: Gait speed and plantar surface contact area, pain visual analogue scale (VAS), Berg Balance Scale, Modified Ashworth Scale, activity level measured on pedometer and compliance via logbook.Results: There were no significant differences between the groups. Both groups showed non-significant improvements in gait speed (toe spreader 0.34 (0.26) versus 0.37 (0.29) m/s; control 0.40 (0.27) versus 0.50 (0.17) m/s), activity level, step length of the hemiplegic leg and stride length at six months. All participants in the intervention group used the toe spreader less than 50% of the days, indicating suboptimal compliance.Conclusion: The use of the toe spreader did not result in significant improvements in any outcomes. Studies with sample sizes of at least 56 participants and strategies to increase compliance to the use of the toe spreader are recommended.

    ABSTRACT: Longitudinally extensive transverse myelitis (LETM) is usually associated with neuromyelitis optica and other autoimmune and inflammatory disorders but this is the first report linking it with dengue fever. Dengue infection can cause a variety of neurological complications which may result in poor recovery and long-term disability. The authors report here a patient who developed LETM in the para-infectious stage of dengue fever. The patient had a complicated clinical course resulting in severe paraparesis and urinary retention. Treatment with immunoglobulins and antiviral agents supported by a spell of early intensive rehabilitation programme produced excellent results in terms of recovery.

    ABSTRACT: A prospective study of 91 consecutive traumatic brain injury admissions to rehabilitation over a 2-year period to determine factors impacting on rehabilitation charges. Discharge records of 91 adult traumatic brain injury patients comprising total unsubsidized billings for each completed inpatient rehabilitation episode were used to derive total charges. Co-variates analysed included demographic, acute traumatic brain injury and rehabilitation variables including the Modified Barthel Index score. The total median rehabilitation charge per episode was S$7845.50 (range: S$970.55-$44,817.20) [1 Euro=S$2.10]. The top 3 contributory median total charges/episode included bed, board and nursing (S$5616.00), occupational therapy (S$606.00), and physical therapy (S$526.00). Patients with lower admission Glasgow Coma Scale scores, longer post-traumatic amnesia duration, dysphagia and medical complications during rehabilitation, lower admission Modified Barthel Index scores, longer acute and rehabilitation length of stay had significantly higher rehabilitation charges (p<0.001). Using multiple regression analyses, only rehabilitation length of stay and change in Modified Barthel Index were significantly correlated with total rehabilitation charges (p<0.001). Measures to reduce rehabilitation length of stay, to prevent medical complications, to facilitate transfers to rehabilitation, and expedient discharge planning may help to reduce rehabilitation charges. This study has potential implications for healthcare resource planning for traumatic brain injury rehabilitation.

    ABSTRACT: Rehabilitation improves functional outcomes, but there is little data on the profiles and outcomes of patients undergoing inpatient rehabilitation in Singapore. The aims of this paper were to document the clinical characteristics and functional outcomes, using the Functional Independence Measure (FIM), of all patients admitted to an inpatient rehabilitation unit in a tertiary teaching hospital, and to identify and analyse factors significantly associated with better discharge functional scores and higher functional gains. In this prospective cohort study over a 4-year period, clinical and functional data for 1502 patients admitted consecutively to the Singapore General Hospital inpatient rehabilitation unit were charted into a custom-designed rehabilitation database. The primary outcome measures were the discharge total FIM scores, FIM gain and FIM efficiency. Multiple linear regression analysis was used to identify independent variables associated with better discharge FIM scores and FIM gain. The mean age was 61.3 +/- 15.0 years and 57.2% of the patients were male. Stroke (57.9%) followed by spinal cord injury (9.7%) were the most common diagnoses. The average rehabilitation length of stay was 21.5 +/- 19.0 days. The mean admission total FIM score was 70.3 +/- 23.2 and the mean discharge total FIM score was 87.3 +/- 23.0, with this gain being highly significant (P <0.001). The mean FIM gain was 17.0 +/- 13.4 and FIM efficiency was 0.95 +/- 0.90 points/day. Factors associated with better functional outcomes were higher admission motor and cognitive FIM scores, male gender, a longer rehabilitation length of stay and the use of acupuncture. Factors associated with poorer functional outcomes were older age, clinical deconditioning, ischaemic heart disease, depression, pressure sores and the presence of a domestic worker as a caregiver. The FIM is an easy-to-use, standardised and robust general measure of functional disability. Multiple demographic, clinical and socio-cultural variables are associated with the primary functional outcomes and should be taken into account in rehabilitation and discharge planning. Nevertheless, rehabilitation improves functional outcomes across a wide range of diagnoses. Further research should be aimed at evaluating long-term disability postdischarge from inpatient rehabilitation and translating these findings into improving rehabilitation and healthcare resource utilisation.
