Pain pattern classification and directional preference for patients with neck pain

Area of Science:

• Orthopedics
• Clinical Outcomes Research
• Pain Management

Background:

• Pain Pattern Classification (PPC) and Directional Preference (DP) are established predictors of healthcare outcomes in orthopedics.
• These classifications guide clinical decision-making for musculoskeletal conditions.

Purpose of the Study:

• To prospectively verify the association between PPC, DP, and clinical outcomes in a cohort of patients.
• To investigate the predictive value of specific classification schemes on pain intensity and disability.

Main Methods:

• A prospective, observational cohort study involving 335 patients.
• Clinical outcome measures (pain intensity, disability) assessed at baseline and follow-up.
• Statistical analyses included chi-squared tests, t-tests, and Tukey's range test.

Main Results:

• Directional Preference (DP) was prevalent in 82.4% of patients.
• The DP with Centralization (CEN) subgroup showed lower average disability (NDI units) and pain intensity compared to Non-DP groups.
• However, patients with DP CEN did not demonstrate clinically significant improvements in pain or disability at follow-up compared to Non-DP groups.

Conclusions:

• The study highlights the high prevalence of DP in the studied population.
• While DP with CEN classification was associated with lower initial pain and disability, its long-term clinical significance requires cautious interpretation due to study limitations.
• Further research is needed to fully elucidate the prognostic value of PPC and DP.
