Understanding Normal Range of Motion for Knee Flexion: A Public Database for Comparison Studies

Knee flexion, an essential aspect of joint mobility, is a crucial indicator of overall health. Measuring range of motion (ROM) is vital for diagnosing and managing conditions that affect joint mobility, such as hemophilia and other bleeding disorders. In this context, understanding normal range of motion values for knee flexion becomes critical.

A recent study published in Haemophilia in 2010 aimed to generate data on normal joint ROM measures that could be used to assess impairment in joint mobility for various patient populations. The study, conducted by the Hemophilia Treatment Center Network and led by Soucie et al., collected ROM measurements of five joints - elbow, shoulder, hip, knee, and ankle - from a sample of over 600 individuals without known medical or physical conditions affecting their joint mobility.

The resulting dataset provides valuable reference values for normal joint range of motion, including values for knee flexion. The data is available in Microsoft Excel or SAS format for public use and can be accessed on the CDC website.

According to the study, normal range of motion values for knee flexion vary by age group and sex. For example, reference values for normal joint ROM - ages 45-69 (males) and ages 20-44 (females) - are provided separately in the dataset. These values can be used as a baseline to compare with people who have bleeding disorders.

The study's objective was to provide a public database of joint ROM measures that could be used to assess impairment in joint mobility for other patient populations, including those with hemophilia and other bleeding disorders. By comparing their ROM measurements with the normal range of motion values, healthcare providers can better understand loss of mobility due to joint bleeding.

Moreover, the study highlights the importance of understanding normal range of motion values for knee flexion as people age. As joints deteriorate over time, individuals without bleeding disorders may experience decreased mobility, which is further exacerbated by chronic joint disease resulting from repeated bleeding into their joints.

In conclusion, the dataset on normal range of motion for knee flexion and other joints provides a valuable resource for healthcare providers to assess impairment in joint mobility for various patient populations. By using this public database, researchers can gain insights into loss of mobility due to joint bleeding and develop more effective management strategies for individuals with hemophilia and other bleeding disorders.
