Do people with #PFP have different biomechanics during walking & running compared to pain-free people? Do altered biomechanics cause #PFP? Check out our new systematic review in @SportsMedicineJ!
Our results might surprise you. A summary follows 🧵1/10

Almost 30,000 studies reviewed!
✅55 studies included: 1,300 PFP, 1,393 pain-free
✅Walking & running
✅Spatiotemoral, kinematic, & kinetic characteristics
✅Subgrouped across sex & task
❌No strong evidence available (very limited-moderate)

People with PFP have altered spatiotemporal characteristics:
⬇️Gait velocity
⬇️Cadence
⬇️Stride length
Future research:
Could spatiotemporal characteristics be used to measure treatment effectiveness?
Is reduced velocity an important variable to measure progression to OA?

People with PFP show peak kinematic differences:
⬆️Contralateral pelvic drop
⬇️Knee flexion
No differences during walking and running in:
❌knee abduction
❌hip adduction
❌internal rotation

Females with PFP show specific differences in peak kinematics:
⬆️Hip flexion
⬆️Rearfoot eversion
❌Very limited research on males with PFP
5/10
⬆️Hip flexion
⬆️Rearfoot eversion
❌Very limited research on males with PFP

People with PFP show:
⬇️peak knee extension moments
🚨This seems to indicate that the quadriceps are important!
❌Very limited # of studies on knee (n=12) or hip (n=3) kinetics.

Only 3 prospective studies exist for gait
❌Only limited conclusions can be made
⬆️Hip abduction (Very Limited)
No differences in:
↔️running cadence (Limited)
↔️hip internal rotation (Very Limited)
↔️rearfoot eversion (Very Limited)

Biomechanics Reporting Checklist was developed
✅Most report equip, samp rates, & variables
❌Jt center & coord system definitions, & segment descriptions often absent
❌17% reported lab-specific reliability
⚠️Needs to be refined & validated further

Huge effort that would not have been possible without @DrChrisBarton, @NatJCollins, @HarviHart, #ChrisLegg, & especially @DrBradNeal who helped with weekly writing meetings to keep me on track. Thank You!

Systematic reviews can take a long time & require consistent & continued effort. If you have given up on one or feel like you want to, that's normal. Keep pushing. This review took 5 years to complete. Find great people to work with who will keep you on track & accountable. 10/10
