How to read the lab
Short notes for students and staff. Written so a methods section can cite the convention, not so a clinic can bill a diagnosis.
Kinematics · 6 min
Joint angle conventions
How Kineos reports flexion, extension and the ISB sign convention — and why 0° is never ‘straight’ in every joint.
Kinetics · 8 min
Inverse dynamics in one page
From ground reaction force to a joint moment — the free-body diagram students actually need.
Power · 7 min
The countermovement jump
Unweighting, braking, propulsion, flight, landing — and why jump height is an impulse story.
Power · 5 min
Reactive strength and the drop jump
RSI = jump height / ground contact time. A stiffness test, not a jump-height test.
Clinical · 6 min
Bilateral symmetry indices
SI% = |L − R| / [(L+R)/2] × 100. The 10% rule, and when it misleads.
Anthropometry · 7 min
The phantom stratagem
Ross & Wilson’s 170.18 cm unisex phantom — why we scale girths before we talk about ‘small’ or ‘large’.
Gait · 6 min
The gait cycle
Stance 60%, swing 40%, and the three rockers of the ankle — a lab walkthrough.
Clinical · 5 min
Knee valgus as a 2D signal
What a frontal-plane single-leg squat can and cannot tell you about ACL risk.

Writing this up
A methods paragraph you can actually paste into a lab report — and what you must not claim.
