Which technique would be most appropriate to increase stability in a patient with low postural tone?

• A. Slow regular rocking
• B. Continuous pressure to skin
• C. Low frequency vibration
• D. Joint approximation through the shoulder to the trunk

Answer: (D)

Proximal joint compression through joint approximation provides essential proprioceptive input that enhances stability when postural tone is low. By pressing from the shoulder toward the trunk, joint receptors in the shoulder girdle and spine are stimulated, promoting automatic co-contraction of the surrounding muscles. This creates a more stable base, improves alignment, and helps the nervous system recruit trunk and proximal muscles during weight-bearing tasks. The result is better postural control and reduced sway. Rocking offers rhythmic sensory input but doesn’t reliably boost proximal stability. Continuous pressure on the skin gives tactile input without engaging the joint proprioceptors needed to stabilize the trunk. Low-frequency vibration can increase overall muscle activity but is less targeted for improving stability. Joint approximation, by providing direct compressive proprioceptive feedback to the joints, best supports stability in someone with low postural tone.
