Trial summary
The main hypothesis of the present study is that a safer knee joint is likely to encourage post stroke patients at an early stage to rely on their hemiparetic leg and transfer their weight onto it while walking. Read more about this study

About this study
Official title: Projet GonioSEF: Etude de faisabilité d'un Dispositif d'amélioration du défaut de Report d'Appui Pendant la Marche en Phase Portante Chez Des Sujets présentant Une Atteinte du système Nerveux Central
The main hypothesis of the present study is that a safer knee joint is likely to encourage post stroke patients at an early stage to rely on their hemiparetic leg and transfer their weight onto it while walking. The main purpose of the present work is to assess the feasibility of FES-induced muscular control of the hemiplegic knee joint in order to improve stance phase support symmetry recovery in individuals with post stroke hemiplegia. Functional electrical stimulation (FES) is delivered to the quadriceps and hamstrings of the paretic limb based on the real-time estimation of the knee angle and support phase.
Read the detailed description
The process of gait recovery in patients with severe post-stroke hemiplegia requires a significant investment and effort for both the patient and the therapist and is not always leading to a safe and autonomous gait. Increasing the chances for the patients of regaining a functional walking gait within limited timeframes is a challenge. Several studies have focused their attention on the neurological foot in the chronic phase because a poorly controlled foot dorsiflexion is a factor limiting gait recovery and increasing fall risk. Functional Electrical Stimulation (FES) can be used as an alternative to an orthosis to restore walking by activating paralyzed muscles. FES has been extensively studied to correct drop foot by activating foot dorsiflexors or inducing a withdrawal reflex.
Few studies have considered knee joint which has a major role, especially for the quality of the support, and this over the entire cycle of walking. In the initial phase after stroke, ensuring a safe knee control remains difficult because of the associated disorders including the lack of proprioceptive feedback. Classical observed disorders in this population are knee hyperextension during the stance phase (genu recurvatum) and flexed knees (crouch gait). Fixed orthoses are usually used to prevent this by limiting knee flexion or extension over the gait. FES is also an alternative to produce appropriately timed knee flexion or extension. Bioness L300 Plus© device proposes a thigh cuff embedding electrodes stimulating the quadriceps muscles to extend knee at the appropriate time during gait based on shank angle observation. Previous studies have investigated the contribution of quadriceps and gluteus maximus stimulation in improving standing balance and weight transfer or hamstrings stimulation associated to foot dorsiflexors stimulation in improving gait performance.
One of the main objectives of an early rehabilitation is to encourage patients with hemiplegia to rely on their paretic leg and to transfer their weight onto it while walking. Depending on the gait phase, the knee extension and flexion are restricted to a safety range by the adaptive delivery of quadriceps and hamstring electrical stimulation. A sensor network detects gait phases and knee angle evolution from which stimulation levels are modulated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Functional Electrical Stimulation FESOther
Functional electrical stimulation (FES) is delivered to the quadriceps and hamstrings of the paretic limb in patients with hemiplegia. It is based on the real-time estimation of the knee angle and support phase during gait.
| Study group | Role | What they receive |
|---|---|---|
| FES in patients with hemiplegia | Experimental | Patients will be equipped with 5 inertial measurement units. Two wireless bluetooth pressure insoles will be connected to the Raspberry. Electrical stimulation will be delivered via a wireless stimulator to the quadriceps and hamstrings via surface electrodes. Insoles will be used to online analyze Paretic Foot Support to discriminate between stance and swing phases. Stimulation will also be delivered just before initial contact at the end of swing phase. In stance phase, stimulation will be triggered either to quadriceps or hamstrings, depending on the paretic knee angle estimation relatively to the knee angle setpoint defined by the practitioner as the optimal flexion during stance phase (around 5°). Receives: Other: Functional Electrical Stimulation FES |
What is being measured
The primary outcome is the main question the study is designed to answer.
Assymetry of stance phase
symmetry ratio of stance duration between paretic and non-paretic limbs
Measured: 24 hours
Assymetry of weight support in stance phase
percentage of weight supported during stance phase relatively to the total weight
Measured: 24 hours
Secondary outcomes (4)
Comfortable walking speed
The preferred walking speed at which the participant choose to walk and speed at which there is least energy consumption per unit distance
Measured: 24 hours
Cadence
The total number of full cycles on a 10m walking path
Measured: 24 hours
Physiological Cost Index (PCI)
Energy cost in walking. PCI is the ratio of the difference in working and resting mean heart rates (bpm) and the self-selected (comfort) walking speed (m/min). The PCI value reflects the energy expenditure for walking and is expressed as heartbeats per meter.
Measured: 24 hours
Borg score of the exercise intensity
Rating of perceived exertion while walking. Perceived effort of walking using a Borg scale from 6 (no exertion) to 20 (maximum exertion) evaluated by the participant.
Measured: 24 hours
