Biomechanical Comparison of Sit-to-Stand and Squat Using the CRAFT Framework and MAI Motion Analysis
Biomechanical Comparison Using the CRAFT Framework and MAI Motion Analysis

Themes
Scientific Focus
Sit-to-stand and squat are common clinical tasks that expose lower-limb strength, balance, control and neuromuscular coordination. They are often judged qualitatively or through simple counts and timing. The CRAFT framework provides five consistent dimensions — Control, Repetition, Asymmetry, Flow and Twist — through which MAI Motion can compare the two tasks using objective, repeatable metrics.
Why It Matters
Assessing both tasks through a common framework may help identify distinct biomechanical profiles, subtle compensations and asymmetries. The presentation positions the approach as a clinic-ready method for tracking rehabilitation and supporting data-informed decisions while retaining tasks that patients and clinicians already understand.
