Prövning av måttet Läpp-till-Lyft (L-t-L) på vuxna utan sväljsvårigheter
Context: Lip-to-Lift (L-t-L) is a bedside-method for measuring oral transit time at swallow. It was designed for a swallowing examination of persons on nursing homes where weight loss was noted in people with average L-t-L-time >5 seconds (Sandin, 2005). The measurement was validated and evaluated by Eriksson, Bremer Zerpe (2008).
Objectives: The study objective was to examine L-t-L on a group of young adults without swallowing disorders and as to examine the inter- and intra-judgereliability of the measure.
- What is the L-t-L-time for young adults without swallowing disorders?
- Are there any gender differences regarding L-t-L-time?
- How high is the inter/intra-judge reliability of L-t-L?
Method: Examination of L-t-L-time was carried out on 20 young adults, aged 19-27 years, without swallowing disorders after Sandin’s (2005) instructions. Measurements of 20 swallows per person were made.
Results: The average L-t-L-time of young adults without deglutition-difficulties was 1.13 seconds (sd =.14). No significant gender differences were seen. The intra-judge reliability (.63 and .81) was higher than the inter-judge reliability (.58). A higer inter-judge reliability was found at swallowing 1-10 when compared to swallowing 1-5.
Conclusion: The fairly good inter-judge reliability suggests that the measure may have some reliability if the measurement is carried out by different examiners. The relatively high intra-judge reliability indicates that the L-t-L-measurement might be more reliable on follow-ups on patients made by the same examiner.
