Neuromuscular Study to Assess Foot Intrinsic Muscles

Taiwan45 participantsStarted 2016-11-04

Plain-language summary

The purposes of these studies are to investigate: Differences in abductor hallucis muscles'EMG activities during different postural tasks between individuals with normal foot alignment and functional flat foot. Differences in abductor hallucis muscles'H-reflex amplitudes between individuals with normal foot alignment and functional flat foot. Changes in abductor hallucis muscles'EMG activities during different postural tasks after a 3-week short foot exercises training regimen in individuals with functional flat foot. Changes in abductor hallucis muscles'H-reflex amplitudes after a 3-week short foot exercises training regimen in individuals with functional flat foot. hypotheses: Peak-to-peak amplitudes and ratios of abductor hallucis muscles and tibialis anterior muscles during different postural tasks were significantly lower in individual with functional flat foot when compared to those with normal foot alignments. H-reflex amplitudes of abductor hallucis muscles were significantly lower in individual with functional flat foot when compared to those with normal foot alignments. Changes of peak-to-peak amplitudes and ratios of abductor hallucis muscles and tibialis anterior muscles during different postural tasks were significantly different in individuals with functional flat foot after a 3-week short foot exercise training regimen. Changes of H-reflex amplitudes of abductor hallucis muscles were significantly different in individuals with functional flat foot after a 3-week short foot exercise training regimen

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
