Is there preliminary value to a within- and/or between-session change for determining short-term outcomes of manual therapy on mechanical neck pain?

© W. S. Maney & Son Ltd 2014. Objectives: The primary purpose of this study was to determine whether occurrences of within- and between-session changes were significantly associated with functional outcomes, pain, and self-report of recovery in patients at discharge who were treated with manual therapy for mechanical neck pain. A secondary purpose was to determine the extent of change needed for the within- and between-session change in association to function.Methods: This secondary data analysis examined 56 patients who demonstrated a positive response to manual therapy during the initial assessment within a randomized controlled trial (RCT) that examined manual therapy techniques and a home exercise program (HEP). Within- and between-session findings were defined as ‘changes in pain report during the initial session (within)’ and ‘changes in pain from baseline to 48-hours post initial assessment (between)’. Outcomes were analyzed for associations with the global rating of change (GRoC), self-report activity scale (SRAS), and a 50% reduction of the neck disability index (NDI) by discharge at 96 hours.Results: Findings indicate that within-session pain changes of 36.7% are strongly associated with a 50% change in NDI at 96 hours. Between-session changes in pain were associated with 50% change in NDI and a ≥3-point change in GRoC at 96 hours.Conclusion: Both within- and between-session measures may be useful to predict success levels at 96 hours for NDI; however, between-session changes are more useful to predict success in GRoC. Measures used during clinical examination may help guide clinicians in identification of candidates best suited for the treatment.
