**9. Interpretation**

Before the intervention program, using the Kaltenborn's convention, patient RB1's **Range of Motion (ROM) was 8-0-4 as against the normal values 15-0-20** (see Whittle, 2003 for normal ranges for gait parameters). **The ROM was improved to 15-0-8 after the intervention program.** This means that patient RB1 had reduced dorsiflexion and plantar flexion due to spasticity before the intervention program but his ankle joint gained more movements after the program.

Patient EO2's ROM was 27-0-10 before the intervention but changed to 25-0-14 (normal values are 15-0-20). This means that his excessive dorsiflexion 27 was reduced to 25, and he had increased plantar flexion. Excessive dorsiflexion has been linked with tibia tilt, which presents a challenge for normal walking, hence the improvement observed in his walking skill.
