Hypothesis

Can the fractal dimension technique provide a better understanding of postural control in patients with Prader-Willi Syndrome compared to traditional methods?

Conclusion

The fractal dimension method offers a more informative description of postural deficits in Prader-Willi Syndrome than traditional time and frequency domain analyses.

Supporting Evidence

  • PWS patients showed greater displacements in both antero-posterior and medio-lateral directions compared to controls.
  • Fractal dimension values were higher in PWS individuals, indicating a more complex postural control pattern.
  • Frequency analysis showed no significant differences between PWS and control groups.

Takeaway

This study looked at how people with Prader-Willi Syndrome stand and balance. It found that a special math method called fractal dimension helps us understand their balance better than just looking at how they move over time.

Methodology

The study involved 11 patients with Prader-Willi Syndrome and 20 age-matched controls, using static posturography to analyze their postural control through time, frequency, and fractal dimension techniques.

Limitations

The small sample size limits the strength of the findings, and the comparison with normal-weight individuals may not isolate the effects of obesity from those of the genetic disorder.

Participant Demographics

11 adult patients (5 males, 6 females; age: 34.4 ± 3.7 years) with Prader-Willi Syndrome and 20 age-matched controls (10 males, 10 females; age: 31.4 ± 9.6 years).
