Descriptive statistics for adherence, modified Oswestry Disability Questionnaire (MODQ), and pain across the different phases of the experiment

	Measurement
	Adherence†		MODQ‡		Average Pain (NRS)§
Group	Booster	Post-Booster	Booster	Post-Booster	Booster	Post-Booster
MST
No additional boosters (1 Booster), n=27	73.1 (22.5)	77.0 (17.6)	9.4 (9.0)	7.87 (7.4)	1.19 (1.33)	1.28 (1.14)
Additional boosters (>1 Booster), n=6	75.2 (14.1)	84.2 (9.8)	14.0 (8.7)	17.4 (17.9)	1.67 (1.03)	2.07 (1.62)
SFE
No additional boosters (1 Booster), n=7	46.9 (34.3)	57.2 (32.1)	20 (8.87)	19.8 (9.0)	2.14 (1.21)	2.04 (1.20)
Additional boosters (>1 Booster), n=17	31.4 (23.2)	50.0 (17.8)	19.5 (10.5)	20.0 (13.2)	2.41 (1.58)	2.30 (1.63)

Note that all values are presented as Mean (SD). For adherence, the “Booster” phase refers to adherence in the month immediately before the first booster session. For MODQ and average pain symptoms the “Booster” phase averages across all boosters attended, and then averages across participants. In the Post-Booster phase (the six months following the last booster), we averaged across all available data points within a subject, and then averaged across participants to get a group level average over time. MST = motor skill training; SFE = strength and flexibility exercise.

^†Adherence scores range from 0–100% with higher scores indicating better adherence.

^‡MODQ ranges from 0–100% with lower scores indicating less disability.

^§Numeric Pain Rating Scale (NRS) ranges from 0–10 with lower scores indicating less pain
