- Abstract
Introduction: Latent trigger points (TrPs) are a type of musculoskeletal disorder. That can detrimentally affect athletic performance. Purpose: This study to classify athletes into latent-trigger point (L-TrPs) and non-trigger point (non-TrPs) group base on pain pressure threshold (PPT), force production and range of motion (ROM). Materials and methods: Total 45 L-TrPs and 45 non-TrPs athletes were selected. The diagnostic criteria proposed by Simons were employed to identify L-TrPs. Pressure algometry was used for PPT, HUMAC NORM ISOKINETIC machine for force production and Kinovea software for ROM analysis. Independent t test and discriminant analysis were conducted. Standardized discriminant coefficient, canonical correlation and Wilks' Lambda was calculated and p-value was judges at 5% level of significance. Results: Standardized discriminant coefficient showing that Average PPT hold first position followed by Average Extension ROM followed by Average Flexion ROM while Average force production stands on last position for discriminating ability to classification of the L-TrPs and non-TrPs among the athletes. It also observed that by using PPT, force production, and ROM, the model accurately classifies athletes with both L-TrPs and non-TrPs, with an accuracy ranging from 85% to 93%. This highlights the potential significance of these factors in distinguishing between athletes with and without TrPs. Conclusion: From this statistical analysis it concluded that PPT is the most significant contributor to classify the latent and non-TrPs groups. Therefore, regular pain assessment is required to maintain the performance of an individual. Whereas force production and ROM should not be ignored as the model 85%-95% accurately classifies these groups.
