Objectives

Narrative objectives1

The objective of this study is to clarify the changes in muscle activity of the paretic lower limb that result from one month of walking practice using a knee-ankle-foot orthosis (KAFO) with a knee extension assist mechanism in stroke patients with hemiplegia presenting with severe gait impairment in the subacute phase.

Key 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).

Key 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.

Other related information

This study is a retrospective observational study using medical record data. It included 13 stroke patients with hemiplegia who were hospitalized between August 2023 and February 2025 and received a knee-ankle-foot orthosis KAFO with an assisted knee extension mechanism. The observation period covered the entire duration from admission to discharge mean 163.5 days. Changes in the primary outcomes muscle activity of the paralyzed side rectus femoris muscle and functional independence measure FIM were explored before and after intensive walking training using the KAFO.

This study is a retrospective observational study and subject enrollment occurred prior to the protocol finalization date July 31 2023. Ethical approval was obtained on April 30 2024 after UMIN registration approval number SJF-20240430.
