HTMR Workshop, th Century Motion Analysis Many descriptive studies More Recently Hypothesis-driven research Modeling more common Historical Comments

HTMR Workshop, 2006Outline Historical Comments Qualitative Applications Quantitative Applications

HTMR Workshop, 2006 Qualitative Applications Question: How can clinicians (e.g., athletic trainers) improve the rehabilitation of injured athletes?

HTMR Workshop, 2006 Qualitative Applications Application: Record baseline, “healthy movement profiles” for possible, post-injury comparison. Dartfish sample video

HTMR Workshop, 2006 Qualitative Applications Example: golf Dartfish non-numerical cues & tools “key positions” easily shared Dartfish high school golfer

HTMR Workshop, 2006 Qualitative Applications Example: squat poor form Dartfish UNC Human Performance Lab

HTMR Workshop, 2006 Qualitative Applications Example: squat good form Dartfish UNC Human Performance Lab
