Trunk-oriented Exercises Versus Whole-body Vibration on Abdominal Thickness and Balance in Children with Duchene Muscular Dystrophy.

Children with Duchenne muscular dystrophy gradually lose strength in the muscles closest to the trunk and hips, which makes it harder to hold a steady posture and balance during everyday movement and walking. This small trial asked whether adding trunk-focused exercises or whole-body vibration to standard physical therapy would better support the abdominal muscles and balance. Thirty boys aged six to ten were randomly split into two groups: one did trunk-oriented exercises alongside their usual therapy, the other added whole-body vibration instead, both for three months. Both groups improved on the measures of abdominal muscle thickness and balance after treatment compared to before.

When the two approaches were compared directly, the trunk-oriented exercise group came out ahead. This suggests targeted trunk work may offer an edge over vibration therapy as an add-on, though with only thirty children studied, the finding is preliminary and needs replication in larger groups before drawing firm conclusions about clinical practice.

If your child has Duchenne muscular dystrophy, you may already know that weakening muscles in the trunk and hips can make balance and posture trickier over time. This study looked at two ways of adding extra exercise to standard physical therapy: one group did exercises focused on the trunk muscles, the other used a vibrating platform (whole-body vibration), both for three months alongside their regular therapy. Both approaches were linked to improvements in abdominal muscle thickness (measured by ultrasound) and balance (measured with a specialized balance testing system) after treatment.

But when researchers compared the two groups directly, the trunk exercise group showed better results than the vibration group. This is encouraging in the sense that it points toward trunk-focused exercise as a promising direction, but the study only included thirty boys, so it's a small piece of evidence. Larger studies would help confirm whether this advantage holds up and translates into meaningful everyday benefits.

For clinicians weighing add-on interventions for postural control in Duchenne muscular dystrophy, this trial offers a direct comparison between trunk-oriented exercise and whole-body vibration, both layered onto a standard physical therapy regimen over three months. The relevant clinical question is which adjunct better supports abdominal muscle thickness and balance in young ambulant or early-stage boys aged six to ten. Thirty participants were randomised into two groups of equal design intent, group A receiving trunk-oriented exercises plus standard therapy, group B receiving whole-body vibration plus the same standard therapy, three sessions weekly.

Both groups showed statistically significant within-group improvement from baseline on Biodex balance system measures and ultrasonographic abdominal muscle thickness. The post-treatment between-group comparison favoured the trunk-oriented exercise group across all measured variables, suggesting a comparative advantage for this specific active comparison rather than proof that vibration is ineffective. The sample size of thirty is small for a progressive neuromuscular population known for clinical heterogeneity, and the abstract does not report long-term follow-up, functional or gait outcomes, or adverse events, limiting how far these ultrasonographic and balance-platform findings translate into durable functional gains or inform broader practice decisions.
