Table 3. Plantar fasciitis results in pain, functional impairment and quality of life impairment of both shockwave and ultrasound groups pre-treatment, post-treatment and at the 4-week follow-up. *Comparison between shockwave and ultrasound groups pre-treatment, post-treatment and at the 4-week follow-up. **Comparison between pre-treatment and post-treatment within each group. ***Comparison between post-treatment and 4-week follow-up within each group.
