Reference Values for the Dynamic Evaluation Method of Lower Limb Joint Alignment (MADAAMI II) for Dancers

Area of Science:

• Biomechanics
• Dance Science
• Sports Medicine

Background:

• Assessing lower limb joint alignment is crucial for dancers to prevent injuries.
• The Dynamic Evaluation Method of Lower Limb Joint Alignment (MADAAMI II) requires established reference values for effective clinical application.
• Previous research has not provided comprehensive reference values for the MADAAMI II method across different age groups of dancers.

Purpose of the Study:

• To propose reference values for the Dynamic Evaluation Method of Lower Limb Joint Alignment (MADAAMI II).
• To determine if age (young vs. adult dancers) influences lower limb joint alignment scores using the MADAAMI II.
• To establish a screening tool for assessing dancer stability and injury risk.

Main Methods:

• 346 dancers (aged 15-58) with at least 5 years of ballet experience were evaluated using the MADAAMI II.
• Dancers performed a three-step sequence (demi plié, grand plié, fondu) in the first foot position.
• Video analysis by a trained evaluator determined Foot, Knee, Pelvis, and General scores; Mann-Whitney U test and percentile calculations (10th-90th) were used.

Main Results:

• No significant difference in lower limb joint alignment was found between young and adult dancers (aged 15+).
• Reference values for MADAAMI II scores were established using the 15th and 85th percentiles.
• Specific score ranges were provided: Foot (31-52), Knee (34-56), Pelvis (40-55), and General (115-156).

Conclusions:

• The established reference values for MADAAMI II are applicable to all dancers aged 15 and older.
• These values serve as a valuable screening tool for evaluating dancer lower limb stability.
• The findings can aid in assessing training program effectiveness and identifying dancers at higher risk of injury.
