Values are expressed as . Pg: comparisons between the LSS group and the control group using independent sample -test; Ps: comparisons between the 2 tests in the LSS group and control group using paired -test. PTI: pressure-time integral. 1^st: first test. 2^nd: second test. T1: hallux. T2–5: toes 2–5. M1: first metatarsal. M2: second metatarsal. M3: third metatarsal. M4: fourth metatarsal. M5: fifth metatarsal. MF: midfoot. LH: lateral heel. MH: medial heel. .
