Comparison of multiple groups using spm1d #249

Dear Dr. Todd,

I have a basic queation. Now, I want to compare waveforms in 3 conditions. For example, n = 28 Condition 1: Normal walking Condition 2: Slow walking Condition 3: Fast walking Variable: Knee sagittal joint angles (one gait cycle)

Can I use spm1d to compare the knee sagittal joint angle waveforms between 3 conditions? If it is possible, would you tell me how to conduct it?

Sincerely yours, Takuma Inai AIST

Hello Takuma, Yes, spm1d can be used to compare three conditions. It sounds like the appropriate function is one of the following:

spm1d.stats.anova1: one-way ANOVA; if different subjects performed the three conditions
spm1d.stats.anova1rm: one-way repeated-measures ANOVA; if each subject performed all conditions.

Here are links to examples:
