As a 10-year-old, I’d start with explanations that were developmentalally appropriate. Also take into consideration cognitive levels. If I was performing physical exams such as checking the range of motion or measuring body parts, I would give clear instructions on why specific measurements are needed. I wouldn’t just state what should be done but also provide context. In order to get the cooperation of the child, it’s important not only to be respectful but also build rapport with him in order for him feel at ease being examined.
A potential assessment would show that younger children are at higher risk due to their independence, exploring new social roles and using more safety procedures/mechanisms when playing in sports. It could lead to more joint injuries from rough play, etc. Based upon the results of my physical examinations, an increase in frequency may be recommended along with advice on how to avoid future problems.
