UE muscle groups play a role in which activities for school-age children with mobility limitations?

• A. Transfers, wheelchair propulsion, and use of assistive devices for gait
• B. Only leg exercises
• C. Facial expressions practice
• D. Speech articulation

Answer: (A)

Upper-extremity muscle groups are central to functional mobility when leg function is limited. For school-age children who rely on their arms for movement, transfers, wheelchair propulsion, and using gait-assist devices are the main activities that require strong, coordinated use of the shoulders, arms, and hands.

Transferring between surfaces (like bed to chair) demands pushing, lifting, and stabilizing with the arms, plus a secure grip. Wheelchair propulsion depends on pushing the rims with the hands, coordinating the shoulder and elbow joints, and maintaining control and speed. Using assistive devices for gait (such as walkers or crutches) also relies on the arms for weight-bearing, balance, and propulsion when leg strength or function is limited.

The other options focus on muscles not primarily involved in mobility tasks. Facial expressions and speech articulation rely on facial and oral muscles, not the upper limbs. Leg-only exercises emphasize the lower extremities and don’t capture the key role of the arms in independent mobility.
