Background/Aims: Foot problems are common in society and can frequently occur during daily life activities. This study aims to investigate common foot problems among healthy young adults and to determine the effects of these problems on physical activity, balance, and musculoskeletal pain. Methods: Demographic data were recorded. Physical activity levels were evaluated using the International Physical Activity Questionnaire short form (IPAQ). Musculoskeletal disorders were assessed using the Extended Nordic Musculoskeletal Questionnaire (NMQ-E). The Foot Function Index (FFI) was utilized for foot function assessment. Balance was assessed using the Single Leg Standing Test. The navicular drop test was conducted for pes planus evaluation, and hallux valgus was assessed using the Manchester Scale and goniometric assessment. Results: Data from 480 participants were analyzed (hallux valgus: 81, pes planus: 204, control: 195). A comparison of balance, FFI, and IPAQ scores revealed that the balance time of participants with pes planus decreased significantly compared to the control group (p<0.05). Significant differences in body pain were found among the groups for the lower back, hip/thigh, and ankle areas (p<0.05). No significant differences were observed among other sub-parameters (p>0.05). In the lower back region, pain was reported by 29 individuals in the hallux valgus group, 163 in the pes planus group, and 13 in the control group (p<0.05). Conclusions: Foot deformities can negatively impact an individual’s foot functionality and balance, leading to pain in various body regions.
