Minimum detectable and minimal clinically important changes for pain in patients with nonspecific neck pain

Abstract

Background: The minimal detectable change (MDC) and the minimal clinically important changes (MCIC) have been explored for nonspecific low back pain patients and are similar across different cultural settings. No data on MDC and MCIC for pain severity are available for neck pain patients. The objectives of this study were to estimate MDC and MCIC for pain severity in subacute and chronic neck pain (NP) patients, to assess if MDC and MCIC values are influenced by baseline values and to explore if they are different in the subset of patients reporting referred pain, and in subacute versus chronic patients.

Time course of neck-shoulder pain among workers: A longitudinal latent class growth analysis

“…Thus, even the trajectory classes with lower pain intensities were considered relevant and potentially reflecting different stages of NSP. However, because of small differences in pain intensity between the subgroups with lower NSP (classes 1-3), their clinical relevance can be questioned (35). On the other hand, it is possible that workers in the asymptomatic trajectory (class 1) are less prone to develop future NSP compared to those with very low NSP (class 2).…”

Randomized clinical trial of multimodal physiotherapy treatment compared to overnight lidocaine ointment in women with provoked vestibulodynia: Design and methods

“…Statistical power analysis examined the requirements to detect a clinically significant difference of 1.5 points between the two treatments with a two-sided significance level of 0.05, 80% power and 3.47 standard deviation [26]. Several studies of musculoskeletal conditions indicated that a reduction of 1.5 to 2.0 points in pain corresponds to a minimal clinically significant difference [56] and [57]. Moreover, the IMMPACT group recommends a 30% pain reduction as a threshold for clinical significance [34]; this would correspond to 1.8 points based on our previous study (baseline average pain of 6/10) [12].…”

The efficacy of surface electromyographic biofeedback assisted stretching for the treatment of chronic low back pain: A case-series

“…PGIC scales are considered to be highly reliable (r = 0.72 to r = 0.90) (Stratford, Binkley, Solomon, Gill, & Finch, 1994; and sensitive with high face validity (Davidson & Keating, 2002;Kovacs et al, 2007Kovacs et al, , 2008. In relation to clinical relevance, strong correlations with patient satisfaction measures have been reported (Spearman correlation coefficients of 0.56 to 0.77) (Fischer, Stewart, & Bloch, 1999), and it may also correlate with physical performance (Osoba, Rodrigues, Myles, Zee, & Pater, 1998).…”
