Can we predict which patients with plantar heel pain are more likely to benefit from insoles? A secondary exploratory analysis of a randomized controlled trial

Table 2 Outcomes at 12 weeks and 26 weeks follow-up

	Follow-up at 12 weeks			Follow-up at 26 weeks
	Sham insole group n = 68 mean (SD) unless otherwise indicated	Custom made insole group n = 66 mean (SD) unless otherwise indicated	Usual care group N = 39 mean (SD) unless otherwise indicated	Sham insole group n = 68 mean (SD) unless otherwise indicated	Custom made insole group n = 66 mean (SD) unless otherwise indicated	Usual care group N = 38 mean (SD) unless otherwise indicated
FFI total score, 0–100	30.3 (21.0)	30.8 (23.2)	30.2 (24.6)	24.6 (24.1)	25.0 (23.1)	22.2 (26.5)
FFI total MID*, N (%)	48 (70.6)	45 (68.2)	27 (69.2)	53 (77.9)	53 (80.3)	30 (78.9)
Recovered**, N (%)	25 (36.8)	24 (36.4)	15 (32.6)	39 (57.4)	35 (53.0)	21 (55.3)
First step pain, 0–10	5.0 (3.0)	5.0 (3.0)	4.0 (0.0)	3.0 (3.0)	4.0 (4.0)	3.0 (3.0)
First step pain MID, N (%)***	38 (55.9)	39 (59.1)	23.0 (59.0)	48 (70.6)	43 (65.2)	28 (73.7)

* A patient was considered to have reached a minimal important improvement in FFI if their FFI total score at follow-up was at least 6.5 (the minimal important difference) lower than at baseline
**A patient is defined as recovered if they answered ‘the complaints have completely disappeared or they are strongly improved’
***A patient was considered to have reached a minimal important improvement in first step pain if their first step pain score follow-up was at least 1.9 (the minimal important difference) lower (improved) than at baseline
