Which progression describes arm movements, including two-arm, alternating arms, single-arm, and single-arm with trunk rotation, in proprioception training?

• A. Proprioceptive progression - lower body
• B. Proprioceptive progression - base of support
• C. Proprioceptive progression continuum
• D. Proprioceptive progression - upper arm

Answer: (D)

Proprioception training is advanced by the body region being challenged and the movement complexity. The sequence described—two-arm, alternating arms, single-arm, and single-arm with trunk rotation—specifically targets the upper limb and shoulder region, progressively increasing neuromuscular demands on the arms while also integrating trunk control. This makes it the proprioceptive progression - upper arm, the best label for movements focused on the arms. Other options refer to different focus areas (lower body, base of support) or a generic continuum that doesn’t pinpoint the upper-arm emphasis.
