The story of 6-year-old Nguyen Quoc Tuan at ACC Clinic Hanoi is a real-world testament to this: When a father&#8217;s meticulous observations are addressed by the expertise of motion specialists, a child&#8217;s early steps are built on the most solid foundation.<\/p>\n<h2><span id=\"Meticulous_Parental_Observation_and_the_Expert8217s_Perspective\">Meticulous Parental Observation and the Expert&#8217;s Perspective<\/span><\/h2>\n<p>A year ago, noticing abnormalities in Quoc Tuan\u2019s gait, his family brought him to ACC Hanoi for a screening. Here, he was prescribed custom medical orthotics, scientifically measured and designed by Dr. Erik W. Waardenburg &#8211; a Chiropractic specialist with over 23 years of international experience.<\/p>\n<p>Throughout an entire year, Tuan&#8217;s father closely accompanied his son. He not only reminded Tuan to wear the orthotics for at least 5 hours a day and patiently did the 2-to-3-minute supplementary exercises with him, but also observed his posture changes daily.<\/p>\n<p>During the 1-year follow-up appointment, instead of general questions, Tuan\u2019s father brought highly detailed biomechanical observations to Dr. Erik:<\/p>\n<p><em>\u201cI noticed that the alignment of his left leg seems to be progressing faster and better than the right one.\u201d<\/em><\/p>\n<p><em>\u201cWhenever he sits with a rounded back, I notice his lower spine protruding slightly. Is this dangerous, Doctor?\u201d<\/em><\/p>\n<figure id=\"attachment_12681\" aria-describedby=\"caption-attachment-12681\" style=\"width: 800px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-1.png\"><img loading=\"lazy\" class=\"size-full wp-image-12681\" src=\"https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-1.png\" alt=\"patient-story-nguyen-quoc-tuan-1\" width=\"800\" height=\"420\" srcset=\"https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-1.png 800w, https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-1-300x158.png 300w, https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-1-768x403.png 768w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><figcaption id=\"caption-attachment-12681\" class=\"wp-caption-text\">Quoc Tuan during a routine follow-up with Dr. Erik W.

He explained the biomechanical principles of a child&#8217;s growing body:<\/p>\n<ul>\n<li><strong>Regarding the uneven development between both feet:<\/strong> The human body is not perfectly symmetrical. The muscles and ligaments on one side may react and adapt to the custom orthotics faster than the other. This is a natural adaptation process. The most important thing is that Quoc Tuan&#8217;s overall arch system has<strong> improved dramatically by up to 70%<\/strong>, reducing his flat foot condition to the mildest level (Grade 1).<\/li>\n<li><strong>Regarding the protruding lower back bone:<\/strong> The doctor personally examined Tuan&#8217;s spinal structure on the spot and explained that when a child sits with a slouched or rounded back, the incompletely developed lumbar vertebrae naturally tend to protrude slightly under the skin. This is merely a normal physiological reaction to posture changes, not a physical deformity or scoliosis.<\/li>\n<\/ul>\n<p>The detailed and visual explanation from the specialist completely alleviated the family&#8217;s concerns about their child&#8217;s posture.<\/p>\n<h2><span id=\"Proven_by_Visual_Medical_Imaging\">Proven by Visual Medical Imaging<\/span><\/h2>\n<p>Quoc Tuan&#8217;s treatment results are clearly displayed through clinical indicators and visual imaging from the Swiss-technology CAD-CAM foot scanner and the podoscope.<\/p>\n<figure id=\"attachment_12682\" aria-describedby=\"caption-attachment-12682\" style=\"width: 800px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-2.png\"><img loading=\"lazy\" class=\"size-full wp-image-12682\" src=\"https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-2.png\" alt=\"patient-story-nguyen-quoc-tuan-2\" width=\"800\" height=\"420\" srcset=\"https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-2.png 800w, https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-2-300x158.png 300w, https:\/\/acc.vn\/en\/wp-content\/uploads\/sites\/8\/2026\/06\/patient-story-nguyen-quoc-tuan-2-768x403.png 768w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><figcaption id=\"caption-attachment-12682\" class=\"wp-caption-text\">Visible improvement in Quoc Tuan&#8217;s arches after 1 year of treatment. The arches are lifted, and ankle pronation is reduced by up to 70%.<\/figcaption><\/figure>\n<p>From a flat foot with a tendency to severely collapse inward, Quoc Tuan\u2019s arches now show a distinct curve, and his ankle alignment is much straighter. This allows him to run, jump, and play actively all day without feeling pain, fatigue, or affecting his knee joint alignment.<\/p>\n<h2><span id=\"Maintaining_Recovery_Momentum_Optimizing_Kinetic_Performance_with_a_Second_Pair_of_Orthotics\">Maintaining Recovery Momentum: Optimizing Kinetic Performance with a Second Pair of Orthotics<\/span><\/h2>\n<p>Thanks to the positive recovery of up to 70% from the first pair, combined with the natural growth of Quoc Tuan\u2019s feet over the year, Dr. Erik prescribed an upgrade to a new pair of custom orthotics.<\/p>\n<p>Witnessing the real-world changes in his son&#8217;s active, agile steps, Quoc Tuan\u2019s father decided to order this second pair to continue the treatment protocol. Proactively adhering to the roadmap and upgrading to the next pair based on achieved positive results is a precise investment by parents, partnering with ACC experts to optimize their child&#8217;s kinetic chain during the golden window of development.<\/p>\n<p><strong>Advice from Dr. Erik W. Waardenburg:<\/strong><em> \u201cDo not wait until your child complains of pain to have them examined. Daily observation from parents is invaluable. If you notice your child having an X-legged (knock-knees), O-legged (bow-legs) gait, or walking on tip-toes, bring them in for an early flat foot screening before the age of 12 to achieve the most optimal correction using conservative, non-invasive methods.\u201d<\/em><\/p>\n<p><strong>CONTACT INFORMATION<\/strong><\/p>\n<p><strong>American Chiropractic Clinic (ACC) \u2013 A Member of FV Group<\/strong><\/p>\n<p>Website: <a href=\"https:\/\/acc.vn\/\">www.acc.vn<\/a><\/p>\n<ul>\n<li>HCMC: 99 Nguyen Du, Ben Thanh Ward, District 1 Tel: (028) 3939 3930 | Hotline: +84 946 740 066<\/li>\n<li>HCMC: 1st Floor, Tan Da Court, 86 Tan Da, Ward 11, District 5 Tel: (028) 3838 3900 | Hotline: +84 941 970 909<\/li>\n<li>Hanoi: 1st &amp; 2nd Floor, HDI Tower, 55 Le Dai Hanh, Hai Ba Trung District Tel: (024) 3265 6888 | Hotline: +84 965 688 828<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>ContentsMeticulous Parental Observation and the Expert&#8217;s PerspectiveInsights from the &#8220;Expert in Motion&#8221;Proven by Visual Medical ImagingMaintaining Recovery Momentum: Optimizing Kinetic Performance with a Second Pair of Orthotics On a child\u2019s physical development journey, parental attentiveness combined with an accurate clinical diagnosis is the key to protecting their kinetic chain.
