Hypermobility Spectrum Disorder (HSD) is a condition characterized by excessive joint flexibility, which can lead to joint pain and instability. Individuals with HSD may experience a range of symptoms, including fatigue, muscle weakness, and frequent injuries. The condition exists on a spectrum, meaning that some people may have mild symptoms while others may face more significant challenges in daily activities. Diagnosis of HSD typically involves a thorough assessment of joint mobility and a review of symptoms. It is important to differentiate HSD from other related conditions, such as Ehlers-Danlos Syndrome, to ensure appropriate management and treatment. Physical therapy and lifestyle modifications can help improve joint stability and overall function.
