Add spatiotemporal gait parameters

[JuliusWelzel]

If ICs and FCs are detected using any of the algorithms it should be possible to derive some basic gait parameters from those. Add references to each function.

Parameters of interest: Temporal parameters

• [ ] step time
• [ ] stride time
• [ ] variability
• [ ] asymmetry
• [ ] Double support time
• [ ] Stance time

Spatial parameters

• [ ] step length
• [ ] stride length
• [ ] ...

@rmndrs89 Could you check with Clint which parameters of interest?

Hi @JuliusWelzel ,

thanks for asking, I have some ideas, yes... You can check out these papers for normative spatiotemporal gait parameters in older adults (Hollman et al., Gait & Posture, 2011) or people with Parkinson's disease (Hass et al., PLoS ONE, 2012).

Basically, it boils down to:

Spatial parameters

• [ ] step length (cm)
• [ ] step width (cm)
• [ ] stride length (cm)

Temporal parameters

• [ ] step time (s)
• [ ] stride time (s)
• [ ] stance time (s)
• [ ] swing time (s)
• [ ] single support time (s)
• [ ] double support time (s)
• [ ] cadence (steps/min)

Spatiotemporal parameters

• [ ] gait speed (cm/s), the distance walked divided by the ambulation time
• [ ] stride speed (cm/s), the stride length divided by the stride time

Temporophasic parameters

• [ ] stance time (%GC)
• [ ] swing time (%GC)
• [ ] single support time (%GC)
• [ ] double support time (%GC) where %GC stands for % gait cycle

Maybe we can implement these normative values also, somehow? Would that make sense? We could have something like Moe-Nilssen and Helbostad, Gait & Posture, 2022
