The Lower Limb Tasks Questionnaire: Is It Useful in the Assessment Of Function in Low Back Pain Sufferers?
type: CreativeWork
description: Objective: The objective of this study was to investigate selected measurement properties of the Lower Limb Tasks Questionnaire (LLTQ) in a sample of acute Low Back Pain (LBP) subjects, and compare these findings to the Roland Morris Questionnaire (RMQ). The primary aim of the study was to investigate the responsiveness and minimal clinical important difference (MCID) within this population. Additionally, an analysis of the content and construct validity of the LLTQ was undertaken. Study Design: A quantitative prospective evaluation of outcome measures, assessing limitations in physical function change over a course of treatment. Background: Low Back Pain (LBP) is a common condition associated with a loss of function. As restoration of function is a major aim of physiotherapy management and the utilisation of outcome measurements is a fundamental requirement of practice, clinicians must have measures that can detect meaningful change in this construct. The LLTQ is an outcome measure which has been used for populations with lower limb conditions, and in this population it has been shown to demonstrate sound psychometric properties. It offers potential advantages to clinicians and researchers relating to its scoring system, its ability to delineate functional tasks relating to activities of daily life and recreation and to assessing the importance of tasks to the individual. Methods: Sixty nine subjects who presented for physiotherapy treatment with acute LBP completed the LLTQ and RMQ at the initial visit, when a level of ‘improved’ had been reached using a 7 point Global Perceived Effect score (GPE), and at discharge. Statistical procedures included, analysis of importance rating data and correlation analysis between baseline LLTQ and RMQ scores to investigate content and construct validity respectively. Responsiveness was estimated using distribution based analyses of effect size, the standardised response mean (SRM) and the minimal detectable change (MDC) for both…
