Inclusion criteria
Inclusion criteria: 1. Unilateral transtibial amputation < 12 months or received new prosthetic components 2. Medium to long residual limb length (over 30%: Stump length is classified by the ratio of the stump length to the sound leg length) 3. Age between 18-75 years old 4.

Participants can walk for a long time, at least 10 meters, on their own without any help or any gait aid 6. Participants must be in good general health, defined as having no acute medical conditions, no uncontrolled chronic diseases (e.g., uncontrolled hypertension or diabetes), and no recent history of hospitalization or major surgery within the past three months. 7. Normal range of motion (ROM) in all joints the lower limb joints 8. Lower limb muscle strength grade 4-5 according to Oxford scale 9. Able to comply with directions and comprehend written and spoken Thai 10. MIQ-RS score > 4 (Movement Imagery Questionnaire-Revised Second Version) (35) 11. A 1:1 ratio of right-handed to left-handed individuals will be maintained, with equal numbers of participants in each group.
