Which technique is MOST appropriate for a patient with low postural tone?

• A. Slow regular rocking while sitting on a treatment bolster
• B. Continuous pressure to the skin overlying the back muscles
• C. Low-frequency vibration to the back muscles
• D. Joint approximation applied through the shoulders to the trunk

Answer: (D)

When someone has low postural tone, the goal is to boost proximal trunk stability so the person can sit and stand with better alignment. Applying joint approximation through the shoulders into the trunk provides deliberate compression that stimulates proprioceptive receptors around the spine and girdle. This input encourages the muscles of the back and abdomen to co-contract, increasing spinal stability and promoting an upright, supported posture. It directly targets the proximal support needed for postural control, making it the most effective technique for hypotonia affecting the trunk. Other methods offer sensory input or promote movement, but they don’t engage the trunk’s proximal stability to the same extent. Gentle rocking mainly alters vestibular input and tone without specifically building trunk stabilization; sustained skin pressure provides superficial sensory cues but not the deep proprioceptive facilitation of the joints; vibration can transiently excite muscles but isn’t as targeted toward improving upright postural control.
