The interventions included contract-relax stretching, resistance training (D1/D2 diagonal patterns), and functional exercises. The assessed outcomes were muscle strength, spasticity, ankle dorsiflexion ROM, and functional mobility.<br> <strong>Results</strong>: Following the intervention, all outcomes significantly improved. Tibialis anterior (TA) strengthened grade 2 to 3 (P<0.001, r=0.62), and 42% achieved grades 4&ndash;5. There were large effect sizes for the quadriceps, hamstrings, and calf muscles (r=0.51&ndash;0.62). TA spasticity dropped from grade 3 to 2 (P<0.001, r=0.75), and 68% reached grade &le;2. Functional mobility improved by 5.21 cm (P<0.001, r=0.83), and ankle dorsiflexion ROM increased by 8.5&deg; (P<0.001, r=0.52).<br> <strong>Discussion</strong>: Diagonal patterns and resistance training decrease the degree of spasticity and increase strength and mobility, making it possible to use this PNF type even in comparison to shorter-term protocols. These findings support the use of PNF to address foot drop in stroke rehabilitation.</div> Hemiplegia, Foot drop, Proprioceptive neuromuscular facilitation (PNF), Stroke rehabilitation 331 338 http://irj.uswr.ac.ir/browse.php?a_code=A-10-2527-1&slc_lang=en&sid=1 Zainab Ali Hussein zainb.A.H2005@mtu.edu.iq 0009-0007-5499-5508 Yes Department of Physiotherapy Techniques, College of Health and Medical Technologies, Middle Technical University, Baghdad, Iraq.
