If a device is too tall, which outcome is expected?

• A. Knee hyperextension
• B. Ankle dorsiflexion
• C. Shoulder elevation
• D. Head rotation

Answer: (C)

When the device is too tall, your arms must reach up to grab the handles, so your shoulders rise toward your ears. This causes shoulder girdle elevation and increased tension in the upper traps, often leading to a stiffer, less comfortable posture and possible neck strain. The height mainly affects upper-body alignment, so lower-limb positions like knee hyperextension or ankle dorsiflexion, and even turning the head, aren’t directly caused by handle height in the same way. The practical fix is to lower the device so your elbows can stay comfortably slightly flexed and your shoulders can remain relaxed, with the wrists in a neutral position.
