ABSTRACT

STUDY DESIGN: Cross-sectional study. OBJECTIVES: To assess the interrater reliability and validity of the test-table-test (TTT) with which paralympic sports participants involved in Nordic sit-ski sports may be classified. SETTING: Movement laboratory in a rehabilitation centre, The Netherlands. METHODS: Thirty-three persons with a spinal cord injury caudally to Th2, a leg amputation, poliomyelitis affecting the trunk and/or lower extremities, or cerebral palsy participated. Subjects were classified according to a classification system for Nordic skiing (that is, five subclasses between LW10 and LW12) by two raters, involving, among others, a combination of four balance tests called TTT. The validity of the TTT was investigated using a gold standard, involving balance perturbation tests on a force plate and centre of pressure (CoP) displacement measurements. RESULTS: As for the interrater reliability, Spearman's rank-correlation coefficient was 0.95 (P<0.001). As regards the validity of the TTT, correlation coefficients ranging from 0.61 to 0.74 (P<0.001) were found when comparing the data with the gold standard. CONCLUSION: Interrater reliability was high in both scoring and classification. With regard to TTT validity, strong positive correlations between CoP displacement and TTT classification were found. Overall, the results of this study show that the TTT is a reliable and valid test. However, the relations between TTT and CoP displacement in the LW10 and LW10.5 subclasses found in this study are somewhat vague, which could be due to the small number of participants in these subclasses. For the LW10 and LW10.5 subclasses further refinement of the four tests within the TTT is warranted.

ABSTRACT

In The Netherlands it has been shown that people in contact with pigs have a higher risk of meticillin-resistant Staphylococcus aureus (MRSA) carriage than the general population. Isolates of closely related spa types, corresponding to multilocus sequence type (MLST) ST398, were found in pig farmers, pig veterinarians and pigs. The objective of this study was to investigate whether contact with pigs and veal calves or other livestock is a risk factor for MRSA carriage in Dutch healthcare workers (HCWs). HCWs at four general hospitals and one university hospital were asked to fill in questionnaires covering contact with animals and to take MRSA cultures of their throat and nares. Cultures of HCWs in contact with livestock were processed with samples from HCWs with no contact with livestock as controls. Seventy-seven of 1721 HCWs (4.4%) reported direct or indirect contact with pigs and/or veal calves and 145 reported contact with other livestock animals. The MRSA carriage rate in the group in contact with pigs and veal calves was 1.7% and in the control group was 0.15%. No carriers were found among HCWs in contact with other livestock. An estimated 3% of hospital staff working in Dutch hospitals serving rural populations belong to a high risk group for MRSA carriage according to the Dutch guidelines. Although MRSA carriage in HCWs in contact with livestock is 10-fold higher than in other HCWs, the difference is not statistically significant.
