PainSci commentary on Rathleff 2015: ?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense.

Raise a little heel 🎶 raise a little heel 🎶 raise a little heel! If you don’t like what you got, why don’t you change it? If you know there’s something wrong why don’t you right it?
Trooper, from the classic song, “Raise a Little Heel”
In 48 plantar fasciitis patients, Rathleff et al. compared the effect of stretching to heel raises (AKA repeatedly standing up on your tip-toes). A towel was inserted under the toes for a little extra angle. When patients were able to comfortable manage a dozen slow lifts every other day, they added weight: a backpack full of books. Elegant simplicity! They kept this regimen up for several months … but it didn’t take long to help. Although everybody got better eventually, the heel raisers got better a lot quicker than the stretchers. They were already much better off after three months.
This isn’t proof that heel raises are going to work … but it’s more than good enough to justify trying it. Obviously we’ll hope to see replication by other researchers.

The aim of this study was to investigate the effectiveness of shoe inserts and plantar fascia-specific stretching vs shoe inserts and high-load strength training in patients with plantar fasciitis. Forty-eight patients with ultrasonography-verified plantar fasciitis were randomized to shoe inserts and daily plantar-specific stretching (the stretch group) or shoe inserts and high-load progressive strength training (the strength group) performed every second day. High-load strength training consisted of unilateral heel raises with a towel inserted under the toes. Primary outcome was the foot function index (FFI) at 3 months. Additional follow-ups were performed at 1, 6, and 12 months. At the primary endpoint, at 3 months, the strength group had a FFI that was 29 points lower [95% confidence interval (CI): 6-52, P?=?0.016] compared with the stretch group. At 1, 6, and 12 months, there were no differences between groups (P>0.34). At 12 months, the FFI was 22 points (95% CI: 9-36) in the strength group and 16 points (95% CI: 0-32) in the stretch group. There were no differences in any of the secondary outcomes. A simple progressive exercise protocol, performed every second day, resulted in superior self-reported outcome after 3 months compared with plantar-specific stretching. High-load strength training may aid in a quicker reduction in pain and improvements in function.
