    This discussion on foot and ankle exercises to attenuate abnormal pronation, to me, is a poor approach to the problem. Yes, it will control the symptom (abnormal pronation), as long as you faithfully do the exercises, but it Does Not address the primary etiology (the pathology causing the abnormal pronation).

    I have made this statement many, many times on this forum. Treat the cause, not the resulting symptoms. So why do we persist in simply treating symptoms?

    In your opinion what is the cause of excessively pronated feet, Brian?
    Could you please reply omitting any descriptive labels you yourself have coined but instead stick to terms in general use in the biomechanics world. Also, please omit any ref to embryology since you can't treat pts at this stage.

    The answer to your question lies in my 50 plus years of research, which incidentally, has introduced new terms into the biomechanical publications (e.g., BioImplosion, Gravity and Hip Drive Pronation).

    IMO, two of the most common causes of Gravity Drive Pronation are: RFS and PCFD

    Here is a link to a meta- analysis of research into the use of exercises to treat flat feet . The meta-analysis looks at only randomized controlled trials .
    Have your insoles/orthotics ever been the subject of a randomized controlled trial ? If so could you provide a reference.


    Effects of the Short-Foot Exercise on Foot Alignment and Muscle Hypertrophy in Flatfoot Individuals: A Meta-Analysis

    Abstract

    This study aimed to conduct a meta-analysis of randomized controlled trials to examine the effects of the short-foot exercise (SFE) compared to foot orthosis or other types of interventions. Eligibility criteria involved participants with flatfoot engaging in the SFE compared to other forms of intervention or control groups without specific intervention. Relevant studies published before the end of June 2022 were identified from databases. A meta-analysis was performed by calculating the mean differences (MD) and standard MD (SMD) using the random effects model. Six trials with 201 patients (out of 609 records) that met selection criteria were reviewed. Five of the six trials implemented distinct interventions in the control group such as shoe insoles and muscle strengthening exercises, while in the remaining trial, controls received no intervention. The SFE group significantly reduced the navicular drop test (NDT) values (MD: -0.23; 95% confidence interval: -0.45 to -0.02; p = 0.04) and the foot posture index (FPI-6) score (MD: -0.67; 95% confidence interval: -0.98 to -0.36; p < 0.0001) when compared to the control group. The muscle hypertrophy did not differ significantly between the groups. The SFE may contribute more benefits than other intervention as it affects flatfoot individuals' foot alignment. Hence, the SFE is recommended as a beneficial dynamic support when facing flatfoot problems.

    Talking about the plantar intrinsic foot muscles, an enlightening paper has just been published by K.M Rowley et al 2023 http://dx.doi.org/10.37190/ABB-02222-2023-02

    It looked at toe gripping ( pulling a towel towards you with your toes etc) versus toe pushing exercises where you push your toes down but don't curl them.

    The researchers looked at activation of the FHL, an extrinsic toe flexor and activity in FHB, an intrinsic foot muscle, during the toe push and toe curl exercises.

    Here are some of their conclusions and findings.

    "Results
    Overall, participants utilized these two toe flexors completely differently in the two tasks. In the toe-gripping task, the FHL was activated to a much greater extent than the FHB. In fact, 18 our of 20 participants activated FHL at more than seventy percent maximum voluntary contraction and half of participants activated FHB at less than ten percent. In contrast, muscle activation during the toe-pushing task appeared more reliant on the FHB for most participants"


    Worth highlighting : Toe curling exercises hardly activated the FHB muscle much at all with half of the participants reaching less than 10% .

    IMO, if you have an imbalance between the extrinsic and intrinsic toe flexors, you will probably make it worse using toe curls, not better.
