Dysfunction of the pelvic girdle causes alteration of the lumbopelvic muscle supporting function and thus disruption of the load transference through the pelvis.

Walking loads symmetrically the muscles that provide stability to the pelvis for load transference and is an easy way to evaluate bilateral muscle function.

The aim of this study was to find out if mobilisation of the symptomatic sacroiliac joint (SIJ) in chronic low back pain patients could alter the lumbopelvic muscle activity measured by surface EMG (sEMG) on the symptomatic side during walking.

The resulting change in the muscle activity seemed to be relaxation of the muscles evaluated.

The muscles whose activity changed for the most during walking after mobilization of the symptomatic SIJ were biceps femoris, on the right side 17,8% (p= 0.007) and on the left side 12.8% (p= 0.012). The right gluteus medius relaxed 14.4% (p=0.016) and left side 6.1% (p=0.033). Lumbar multifidi reacted more on the right side 14.5% (p=0.003) and on the left the decrease was 8.3% (p=0.021). Oblique abdominal externus muscles showed very little change after intervention.

This study gives us the point of view that the main influence the mobilisation has on SIJ is neurophysiological, reflectoric on muscle tone.

Purpose of the study: There are no previous studies for psychometric properties of Finnish version of Tampa Scale of Kinesiophobia questionnaire (TSK-FIN). The aim of this study was to examine test-retest reliability and comparability of two different methods (paper and computer) for the completion of the TSK-FIN among chronic pain patients.

Material and methods: Reliability was tested by 94 subjects who participated in the in-patient rehabilitation program. Mean age was 46.8 yrs(SD 7.5). The mean Oswestry index was 34.4% (SD 15.2). All subjects completed both versions at the interval of eight hours in two consecutive days. Test-retest reliability of TSK-FIN for the paper and computer sum scores were tested by Intra-class Correlation Coefficient (ICC). Internal consistency was measured by Chronbach’s alfa.

Results: Mean (SD) scores of the paper version were 35.3 (7.8) and 35.6 (7.8). Mean (SD) scores of computer version were 37.1 (8.2) and 36.3 (8.5). Test-retest reliability (ICC) for the paper and computer versions were 0.887 and 0.877 respectively which are both excellent. Intertest reliability (ICC) between paper and computer versions was 0.773 which is acceptable. Both versions demonstrated good internal consistency, Cronbach’s alpha was 0.797 for the paper version and 0.815 for the computer version.

Conclusion: Reliability and internal consistency found in this study were consistent with previous studies. Both versions of TSK-FIN demonstrated acceptable test-retest and intertest reliability and internal consistency suggesting suitability for clinical use. However there was tendency that subjects scored higher (t= 3.564, p=0.001) when using computer version. Further research is required to detect clinical importance of the difference.
