“…For wheelchair users, the continuous pressure on weightbearing areas without relief is a common issue (12). Seat cushions in wheelchairs play a vital role by distributing pressure evenly, preventing tissue deformation, and thus reducing discomfort (13). For symptom alleviation, various therapeutic options are available, including traditional, pharmaceutical, and surgical treatments.…”

Background: Coccydynia, characterized by pain in or around the coccyx, is a condition that is particularly prevalent among wheelchair users due to prolonged sitting. Previous studies have highlighted various factors contributing to coccydynia, including extended sitting on hard surfaces, obesity, and gender-specific susceptibility. Objective: The primary objective of this study was to determine the prevalence of coccydynia among wheelchair users, with a focus on identifying key risk factors such as prolonged sitting, gender, and sitting surface hardness. Methods: This cross-sectional study utilized convenience sampling to gather data from 250 wheelchair users across private/government special education institutes, hospitals, rehabilitation centers, and homes in the South Punjab region. Participants aged 15-60 years using a wheelchair for more than one year were included, excluding those with spinal cord injuries, spina bifida, coccyx fractures, sensory loss, psychological issues, or postpartum women. Data was collected via a self-structured questionnaire, Numeric Pain Rating Scale (NPRS), and Visual Analog Scale (VAS). Statistical analysis was conducted using SPSS version 25, focusing on frequencies, percentages, cross-tabulation, and Chi-square tests. Results: The study found that 72.4% of participants experienced tailbone tenderness, with a significant association between longer wheelchair usage hours and increased tenderness (P < 0.001). A majority of participants (76%) reported tailbone pain, with 72.4% experiencing tenderness. The prevalence of coccydynia was higher in females, and most participants did not use a cushion despite the prolonged sitting. The pain was predominantly described as an ache/dull sensation (89.6%), and it worsened after prolonged sitting in 90.8% of cases. Conclusion: Coccydynia is a prevalent condition among wheelchair users, influenced by prolonged sitting, gender, and the hardness of the sitting surface. The study emphasizes the need for educational interventions, ergonomic wheelchair designs, and the usage of specialized cushions to mitigate the risk and alleviate symptoms.
