Exploring the long-term impact of PNF interventions on plantar fascitis with restricted dorsiflexion using visual analogue scale and foot and ankle ability measure

Introduction. Plantar fasciitis is the inflammation of the plantar fascia, affecting both active and sedentary individuals. Limited dorsiflexion increases tension, worsening symptoms. Diagnosis involves the Windlass test, and PNF shows promise in treatment, though long-term effects need further study. Aim of the study. This prospective longitudinal study aimed to investigate the long-term effectiveness and maintenance strategies following proprioceptive neuromuscular facilitation (PNF) technique interventions in individuals with plantar fasciitis and limited dorsiflexion which is one of the conditions affecting the community. The primary objectives included quantitatively comparing pain levels, functional mobility, and patient adherence to prescribed strategies over an extended follow-up period. Materials and Methods. A cohort of 120 participants with plantar fasciitis and limited dorsiflexion, previously treated with PNF interventions, were enrolled in the study. Follow-up assessments were conducted at three-month intervals over a one-year period. Pain levels were measured using a visual analog scale (VAS), functional mobility was assessed using the foot and ankle ability measure (FAAM), and patient-reported outcomes were recorded. Qualitative insights into maintenance strategies were obtained through in-depth interviews, covering aspects such as home exercise programs, lifestyle modifications, and adherence to recommendations. Results. Statistical analysis revealed a statistically significant (p < 0.05) reduction in pain levels and improved functional mobility over the study period. Recurrence rates were found lower than baseline, with only 15% of recurrence. Logistic regression analysis identified factors contributing to sustained outcomes, including consistent adherence to prescribed home exercises (p = 0.021) and proactive lifestyle modifications (p = 0.035). Conclusion. The study concluded that PNF techniques effectively reduce pain, improve mobility, and sustain outcomes in plantar fasciitis with limited dorsiflexion, highlighting the importance of adherence to exercises and lifestyle modifications.
