Inclusion criteria

Inclusion criteria: Patients with hemiplegia due to stroke admitted to our hospital's recovery-phase rehabilitation ward between August 2023 and February 2025. Patients for whom cerebrovascular disease rehabilitation fees were billed. Patients for whom a custom-made long leg orthosis (KAFO) was fabricated with the goal of improving walking ability. Patients for whom the necessity of KAFO was discussed by a team including a rehabilitation specialist during an orthotic consultation. Patients for whom lower limb muscle activity (EMG) data could be obtained at baseline and 1 month (1M) post-intervention. Patients who provided consent to participate in this study (consent for participation in the study or use of existing data, as this is a retrospective study).

Exclusion criteria

Exclusion criteria: Individuals for whom the purpose of KAFO fabrication was not to acquire walking ability, but rather to improve durability. Individuals prescribed bilateral KAFOs. Individuals with significant orthopedic conditions (as these may affect walking ability). Individuals who were not experiencing their first stroke. Individuals with missing values in the data required for analysis (muscle activity data or FIM scores). Individuals who withdrew during the study period due to poor health or other reasons.

Design outcomes

Primary

Measure	Time frame
Muscle activity ratio during the loading response phase of the paretic rectus femoris muscle (one month after initial measurement (1M))	—

Secondary

Measure	Time frame
Muscle activity ratio of the paretic side rectus femoris during the single-leg stance phase (1 month after initial measurement (1M)) Muscle activity ratio of the paretic side tibialis anterior during the load response phase and single-leg stance phase (1 month after initial measurement (1M)) Lower limb Brunnstrom Recovery Stage (BRS) scores at admission, baseline, 1M, and discharge Functional Ambulation Categories (FAC) scores at admission, baseline, 1M, and discharge Ambulation Independence Measure (AIM) scores at admission, baseline, 1M, and discharge Motor Functional Independence Measure (Motor FIM) scores at admission, baseline, 1M, and discharge Cognitive Functional Independence Measure (Cognitive FIM) scores at admission, baseline, 1M, and discharge Paretic knee joint angle during the loading response phase at baseline and 1M, measured using a markerless motion analysis system (VP-Ergono, NEXT SYSTEM Co., Ltd.) in the sagittal plane	—
