The effects of short foot exercises and arch
support insoles on improvement in the medial
longitudinal arch and dynamic balance of
flexible flatfoot patients

Multiple comparisons using t-test with a Bonferroni adjustment
Within groups rather than between groups analysis
No idea how many randomised to each group (only 14 subjects in both groups!)
The "orthotics" sucked.
Fail. Next.

Effects of Short-Foot Exercises on Foot Posture, Pain, Disability and Plantar Pressure in Pes Planus.
Unver B, Erdem EU, Akbas E. J Sport Rehabil. 2019 Mar 12:1-16
Why do so many ruin what good have been a good study with a crap analysis.
"Navicular drop, Foot Posture Index, pain, and disability scores were significantly decreased, maximum plantar force of midfoot was significantly increased in short-foot exercises group over six weeks (p<0.05). No significant differences were determined between the baseline and the sixth week outcomes in control group (p>0.05)."
They did a within groups analysis rather than a between groups analysis. Also multiple comparisons. next.
The problem is that we do not know if they really did or not. They did the wrong type of analysis, so we do not know if that was really the case or not.
If we agree that the analysis was inappropriate, then how did the work get published in a reputable journal? Is it the reader who must constantly be on top of the research method, analysis and reporting in order to sift the wheat from the chaff?
Very interesting article. We really never had much success with exercises to treat plantar fasciitis or flexible flatfoot. Most patients did not perform the exercises or stretch their arch or Achilles enough to make a difference. We found that a posterior night splint made the most difference short term and long term a heat moldable orthotic long term.
Thanks again for a good read.

Re the above and the strengthening method used , if this does not convince you that the short foot exercise is not a good exercise for the intrinsic foot muscles,
then nothing will .
( Unless you accept that toe flexors flex
the toes and thus allow the ball of the foot to lift clear of the deck during the exercise. )
Training sessions , direct electrical stimulation , lights going on and off
. Good grief !
Can't believe I felt the need to say that , " toe flexors flex
the toes
" .
If Janda believed that ,with his exercise , the intrinsic toe flexors could be strengthened without toe pressure being exerted on the ground , then he got it wrong . Get over it !
