Table 2. Plantar fasciitis results in pain, functional impairment and quality of life impairment of both ultrasound and control groups pre-treatment, post-treatment and at the 4-week follow-up. *Comparison between ultrasound and control groups pre-treatment, post-treatment and at the 4-week follow-up. **Comparison between pre-treatment and post-treatment within each group.
