Clinical Trial Summary

This is an observational study aimed at evaluating the responsiveness and minimal important change of two measures of pain intensity in people with low back pain. It consists of a battery of self-administered questionnaires which will be given to individuals with low back pain to complete before and after a rehabilitation treatment. Relationships among the different outcome measures will be also evaluated.

Description:

This is an observational study aimed at evaluating the responsiveness and minimal important change of two different graphical ways to assess pain intensity in people with low back pain.

Literature found out that low back pain intensity is commonly assessed by a numerical rating scale ranging from no pain to the worst imaginable pain, once presented to responders horizontally. A different way to assess pain intensity could be to answer a similar numerical rating scale if set vertically.

In Literature there are not studies which head-to-head evaluate the responsiveness and minimal important change of these two ways of assessing pain intensity due to low back pain.

Participants will also have to complete self-reported outcome measures of disability, catastrophizing, fear of movement and self-efficacy, and correlations among these tools and the above two different ways to evaluate pain intensity will be evaluated. Descriptive statistics will be presented by taking into account the socio-demographic characteristics of the sample under investigation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	NRS	Numerical Rating Scale; score 0-10 with higher estimates indicating higher levels of pain intensity (horizontal line)	Immediately before the rehab treatment starts and immediately after the intervention
Primary	Gauge of pain	Numerical Rating Scale; score -5/+5 with lower estimates indicating higher levels of pain intensity (vertical line)	Immediately before the rehab treatment starts and immediately after the intervention
Secondary	ODI	Oswestry Disability Index; score 0-50 with higher scores representing greater restriction to activities.	Immediately before the rehab treatment starts and immediately after the intervention
Secondary	PCS	Pain Catastrophizing Scale; score 0-52 with higher estimates showing higher catastrophizing	Immediately before the rehab treatment starts and immediately after the intervention
Secondary	TSK	Tampa Scale of Kinesiophobia; score 13-52 with higher estimates showing higher fear of movement	Immediately before the rehab treatment starts and immediately after the intervention
Secondary	PSEQ	Pain Self Efficacy Questionnaire; score 0-60 with higher estimates showing higher self-effficacy	Immediately before the rehab treatment starts and immediately after the intervention
Secondary	GPE	Global Perceived Effect (how much did the treatment received help your pain?); score -3 (it worsen a lot the things)/+3 (it helped a lot)	Immediately after the intervention
