All of the following can help prevent neck and back strain EXCEPT:

• A. Working with the back straight
• B. Reaching overhead for supplies
• C. Using freestanding shampoo bowls
• D. Adjusting the height of the client's chair

Answer: (B)

Keeping your body in a neutral, relaxed position is key to preventing neck and back strain. When you work with the back straight, your spine stays aligned and you’re not forcing your muscles to compensate, which reduces tension in the lower back and neck. Adjusting the height of the client’s chair lets you position the client and yourself so your elbows stay at a comfortable level, avoiding the need to hunch or lean forward. Using freestanding shampoo bowls adds flexibility to place the bowl where you can work without twisting or bending your neck, helping maintain a natural head and neck posture. Reaching overhead for supplies, on the other hand, tends to pull your arms up and your neck forward, creating awkward angles that strain the neck and back. So, while the first three practices support good posture, reaching overhead for supplies does not and is the one that does not help prevent strain.
