Objective:To study the effect of physical therapy and heel sound feedback on lower limbs motor function, mobility and activities of daily living (ADL) for stroke patients based on International Classification of Functioning, Disability and Health (ICF) core set. Methods:From April, 2018 to May, 2020, 113 stroke patients with motor dysfunction were divided into ischemia group (n = 67) and hemorrhagia group (n = 46) according to the cause of stroke. They received physical therapy for lower limbs and heel sound feedback for eight weeks, and assessed with ICF core set for stroke-gait, Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Timed 'Up and Go' Test (TUGT), and modified Barthel index (MBI) before and after intervention. Results:The main effect of time was significant for qualifiers of ICF core set for stroke-gait, the scores of FMA-LE and MBI, and TUGT time (F > 100.59, P < 0.001), and it improved time by time as Post Hoc test. The main effect of groups was not significant (F < 2.29, P > 0.05), nor as Post Hoc test. The interactive effect between time and groups was significant for TUGT time (F = 6.45, P < 0.01), perhaps improved more in the hemorrhagia group, however, the interactive effect was not significant for the others. Conclusion:Physical therapy and heel sound feedback can improve motor function of lower limb, mobility and ADL for stroke patients.
