Learning Upright Standing on a Multiaxial Balance Board.

Area of Science:

• Biomechanics
• Motor Learning
• Human Postural Control

Background:

• Balance boards are widely used for training standing posture.
• A comprehensive analysis of the learning process for balance board control is lacking.

Purpose of the Study:

• To analyze the learning process and performance changes in maintaining a stable stance on a multiaxial oscillating balance board over short and long periods.

Main Methods:

• Healthy participants performed trials to keep a balance board horizontal.
• Performance was assessed over two sessions with a retention test after one week.
• Analysis included oscillation amplitude, variability, displacement, approximate entropy, and mean power frequency.

Main Results:

• Performance rapidly improved within the first session and was retained after one week.
• Balance was less stable in the anterior-posterior than medial-lateral direction.
• Temporal dynamics and frequency content changes occurred in the anterior-posterior direction during retention.

Conclusions:

• The ability to stand on a balance board is rapidly acquired and long-term retained.
• Asymmetric stability suggests potential transfer of postural strategies from previous experiences.
• Later changes in dynamics may indicate the development of new postural strategies during memory consolidation.
