AI Article Synopsis
- The study aimed to examine how fear-avoidance beliefs affect recovery in functional status for individuals with shoulder impairments during rehabilitation.
- Data from 3,362 patients undergoing shoulder rehabilitation revealed that those with lower fear levels showed greater functional improvements compared to those with elevated fear, especially in specific musculoskeletal disorders.
- Results indicate that fear levels play a role in rehabilitation outcomes, with low fear correlating with better recovery; however, methodological limitations included lack of data on therapists' use of patients' fear levels.
Article Abstract
Background: The influence of elevated fear-avoidance beliefs on change in functional status is unclear.
Objective: The purpose of this study was to determine the influence of fear-avoidance on recovery of functional status during rehabilitation for people with shoulder impairments.
Design: A retrospective longitudinal cohort study was conducted.
Methods: Data were collected from 3,362 people with musculoskeletal conditions of the shoulder receiving rehabilitation. At intake and discharge, upper-extremity function was measured using the shoulder Computerized Adaptive Test. Pain intensity was measured using an 11-point numerical rating scale. Completion rate at discharge was 57% for function and 47% for pain intensity. A single-item screen was used to classify patients into groups with low versus elevated fear-avoidance beliefs at intake. A general linear model (GLM) was used to describe how change in function is affected by fear avoidance in 8 disease categories. This study also accounted for within-clinic correlation and controlled for other important predictors of functional change in functional status, including various demographic and health-related variables. The parameters of the GLM and their standard errors were estimated with the weighted generalized estimating equations method.
Results: Functional change was predicted by the interaction between fear and disease categories. On further examination of 8 disease categories using GLM adjusted for other confounders, improvement in function was greater for the low fear group than for the elevated fear group among people with muscle, tendon, and soft tissue disorders (Δ=1.37, P<.01) and those with osteopathies, chondropathies, and acquired musculoskeletal deformities (Δ=5.52, P<.02). These differences were below the minimal detectable change. Limitations Information was not available on whether therapists used information on level of fear to implement treatment plans.
Conclusions: The influence of fear-avoidance beliefs on change in functional status varies among specific shoulder impairments.
