AIM: The main aim of the present study was to design a new tool called neck pain functional limitation scale (NPFLS) for measuring disability related to neck pain and observe its reliability, concurrent validity and criterion validity.

SETTING AND DESIGN: This study was performed at the institutional hospital.

MATERIALS AND METHODS: A total of 157 subjects (neck pain group) and 25 control subjects (control group) without neck pain were recruited for this study. NPFLS was framed as a new tool for this study, which consisted of 5 domains - pain intensity, activities of daily living, social activities, functional activities and psychological factors. Neck Bournemouth questionnaire (NBQ) was used as a gold standard to measure the concurrent validity and criterion validity of the NPFLS.

STATISTICAL ANALYSIS: Criterion validity and concurrent validity between the neck Bournemouth questionnaire (NBQ) and NPFLS scores were tested statistically using Mann-Whitney U test and Spearman correlation test. The reliability was tested by examining the internal consistency to calculate the Cronbach's alpha value for each item in NPFLS.

RESULTS: No significant difference between NPFLS and NBQ was observed using Mann-Whitney U Test, with P value greater than 0.05 (P= 0.557). Besides that, NPFLS had a high concurrent validity (r= 0.916) and good internal consistency with high Cronbach's alpha value of (r= 0.948), which demonstrated strong correlation between the items of NPFLS and NBQ.

AIM: The study aimed to investigate the effect of P.s on atherosclerotic changes in hypercholesterolemic rabbits.

METHODS: Forty two male New Zealand white rabbits were divided into seven groups. C - control group fed normal rabbit chow, CH - cholesterol diet (1% cholesterol), W1 - 1% cholesterol with water extract of P.s (62.5 mg/kg), W2 - 1% cholesterol with water extract of P.s (125 mg/kg), W3 - 1% cholesterol with water extract of P.s (250 mg/kg), W4 - 1% cholesterol with water extract of P.s (500 mg/kg) and Smv - 1% cholesterol supplemented with simvistatin drug (1.2 mg/kg). All rabbits were treated for 10 weeks. Following 10 weeks of supplementation, the animals were sacrificed and the aortic tissue was taken for histological study.

RESULTS: Rabbits fed only with high cholesterol diet 1% cholesterol (CH) showed focal fatty streak lesions compared to the C group and 1% cholesterol supplemented with simvistatin drug (Smv) group. Atherosclerotic lesions in the 1% cholesterol group supplemented with P.s (500 mg/kg) i.e. W4 group showed significant reduction (30 + or - 6.0%, p < 0.05) in fatty streak compared to the high cholesterol group (85.6 + or - 4.1%) under Sudan IV stain. The atherosclerotic lesions under transmission electron microscope showed reduction in foam cells in the treatment groups compared to the CH groups.

METHODS: Forty two male New Zealand white rabbits were divided equally into seven groups; (i) C- control group fed normal rabbit chow (ii) CH- cholesterol diet (1%cholesterol) (iii) X1- 1% cholesterol with water extract of P.s (62.5 mg/kg) (iv) X2- 1% cholesterol with water extract of P.s (125 mg/kg (v) X3- 1% cholesterol with water extract of P.s (250 mg/kg) (vi) X4- 1% cholesterol with water extract of P.s (500 mg/kg) and (vii) SMV group fed with 1% cholesterol supplemented with simvistatin drug (1.2 mg/kg). All animals were treated for 10 weeks. Blood serum was taken for observing the inflammatory markers at the beginning and end of the experiment.

RESULTS: Rabbits fed with 1% cholesterol diet (CH) showed significant increase in the level of VCAM-1, ICAM-1 and CRP compared to the C group. The levels of VCAM-1, ICAM-1 and CRP in the 1% cholesterol group and supplemented with P.s (500 mg/kg) were significantly reduced compared to the cholesterol group. Similar results were also reported with simvistatin group.

METHODS: Self-administered questionnaires adapted from the Nordic Musculoskeletal Questionnaire were sent to 105 physiotherapists at three main public hospitals in Kuala Lumpur, Malaysia. The questionnaire had 12 items that covered demographic information, areas of musculoskeletal problems and physiotherapy techniques that could contribute to work-related musculoskeletal disorders. The data obtained were analyzed using the Statistical Package for Social Science version 14 software.

RESULTS: The overall prevalence of work-related injuries during the past 12 months was 71.6%. Female therapists reported a significantly higher prevalence of work-related musculoskeletal disorders than the male therapists (73.0%, p,0.001). Significant differences were observed between the proportion of therapists who had work-related musculoskeletal disorders and those who did not for the group with a body mass index (BMI) .25 (x² = 9.0, p = 0.003) and the group with a BMI of 18-25 (x² = 7.8, p = 0.006). Manual therapy (58.6%) and lifting/transfer tasks (41.3%) were the two physiotherapy techniques that most often contributed to work-related musculoskeletal disorders.

AIMS: We assessed outcomes of a pilot long-term stroke care clinic which combined secondary prevention and rehabilitation at community level.

SETTINGS AND DESIGN: A prospective observational study of stroke patients treated between 2008 and 2010 at a primary care teaching facility.

SUBJECTS AND METHODS: Analysis of patients was done at initial contact and at 1-year post treatment. Clinical outcomes included stroke risk factor(s) control, depression according to Patient Health Questionnaire (PHQ9), and level of independence using Barthel Index (BI).

STATISTICAL ANALYSIS USED: Differences in means between baseline and post treatment were compared using paired t-tests or Wilcoxon-signed rank test. Significance level was set at 0.05.

RESULTS: Ninety-one patients were analyzed. Their mean age was 62.9 [standard deviation (SD) 10.9] years, mean stroke episodes were 1.30 (SD 0.5). The median interval between acute stroke and first contact with the clinic 4.0 (interquartile range 9.0) months. Mean systolic blood pressure decreased by 9.7 mmHg (t = 2.79, P = 0.007), while mean diastolic blood pressure remained unchanged at 80mmHg (z = 1.87, P = 0.06). Neurorehabilitation treatment was given to 84.6% of the patients. Median BI increased from 81 (range: 2-100) to 90.5 (range: 27-100) (Z = 2.34, P = 0.01). Median PHQ9 scores decreased from 4.0 (range: 0-22) to 3.0 (range: 0-19) though the change was not significant (Z= -0.744, P = 0.457).

METHODS: In this controlled trial, the experimental group received 30 minutes of virtual reality balance games in addition to 90 minutes of standard physiotherapy. The control group continued with their two hours of routine standard physiotherapy. Both groups received 12 therapy sessions: two-hour sessions twice per week for six continuous weeks. Changes in physical function, activities of daily living and balance ability were assessed using the Timed Up and Go test, 30-second Sit to Stand test, Timed Ten-Metre Walk test, Six-Minute Walk test and the Barthel Index, and static balance was assessed using a probalance board.

RESULTS: Twenty-eight participants completed post-intervention assessments. The results showed a significant within-subject effect on the Timed Up and Go test: F (1, 26) = 5.83, p = 0.02; and the 30-second Sit to Stand test; F (1, 26) = 13.50, p = 0.001. The between-subject effect was not significant (p > 0.05) for any of the outcome measurements.

CONCLUSION: Substituting a portion of the standard physiotherapy time with virtual reality games was equally effective in maintaining physical function outcomes and activities of daily living among community-dwelling stroke survivors.

METHODS: Rats were devided into five groups consisting of three treatment groups and two control groups. Baseline blood investigations were done before and following commencement of treatment. Spontaneous hypertensive rats were treated for 28 consecutive days and the blood pressure was measured weekly.
