ASSESSING THE AWARENESS OF DIFFERENT METHODS OF MEASURING QUADRICEPS LAG AMONG PHYSIOTHERAPISTS IN INDIA: A CROSS-SECTIONAL OBSERVATIONAL SURVEY

Background Accurate assessment of quadriceps lag is essential in musculoskeletal rehabilitation to restore function and prevent long-term disability. This study aimed to evaluate physiotherapists’ awareness, familiarity, and use of various quadriceps lag measurement methods. Material and methods A cross-sectional survey was conducted among 247 physiotherapists across Gujarat, India, between March and July 2023. Data was collected using a structured online questionnaire and analyzed using descriptive statistics. Results Most participants (96%) were aware of quadriceps lag. Goniometry and visual estimation were the most recognized and frequently used methods. Inclinometers, smartphone-based goniometers, wearable biofeedback devices, and advanced imaging methods were less familiar. Some respondents mentioned alternative techniques like tape measurements and gait lab analysis. The majority emphasized the importance of accurate measurement and expressed interest in learning more, particularly through written materials and recordings. Conclusions While general awareness of quadriceps lag is high, knowledge of objective and advanced measurement tools remains limited. Targeted educational efforts could improve clinical assessment practices and enhance rehabilitation outcomes, contributing to better management of musculoskeletal disorders.
