• Question 1
Jordan is now 19-years old. As an infant, Jordan reached many gross motor
skill milestones, such as holding his head up, rolling over, sitting, and
standing, at normal times. However, he was considered a “late walker”
because he took his first steps at 17 months. By 2 years old, his parents
noticed a hyperlordotic posture while he was standing. A Gower's sign and
Trendelenberg gait were noted by age four. Throughout his childhood, he
suffered progressive muscle weakness, especially in the proximal
musculature of the arms, pelvis, and legs. He required orthotic braces to
assist his walking and was confined to wheelchair ambulation by age 13.
At 16, he was hospitalized with bronchitis requiring antibiotic treatment, but
recovered. Jordan has a history of progressive muscle weakness, but no
history of muscle pain or spasm, chest pain, or irregular heartbeat. The only
medications that he normally takes are calcium and fluoride supplements.
Jordan has three siblings. His older and younger sisters have never had any
major medical issues. Jordan’s older brother is also to a wheelchair with
problems similar to Jordan's. No other immediate or distant family members
have musculoskeletal issues.
