Modulation of Ankle Inversion with Dropped Foot Stimulation

Featured Video Play Icon

In post stroke gait –  loss of  ankle eversion can be a significant impediment to independent, safe gait as placement of the foot in a plantagrade position for weight bearing is lost. Loss of eversion may be seen in patients where tibialis anterior (ankle dorsiflexion) function is preserved and hip/knee function are within normal limits. […]

Hemiplegic Gait Improvement with Dropped Foot Stimulation

A 1999 study on stroke gait by Taylor et al., reported a mean 20 % gait speed increase in hemiplegic patients with use of the Odstock Dropped Foot Stimulator (ODFS). This finding has been supported in additional stroke gait studies comparing gait with and without FES intervention. Gait speed data obtained using APDM Mobility Lab […]

2 Channel Neuromuscular Stimulation for Shoulder Subluxation Reduction post Stroke

  2 channel  neuromuscular stimulation can be an effective intervention to reduce shoulder subluxation post stroke. Stimulation Delivery & Electrode Placement: Using the overlapping mode of the Odstock Microstim 2 channel exercise stimulator –one set of electrodes is placed over the anterior & posterior deltoid muscle and a second electrode set  positioned over the middle deltoid & […]

Combining Foot Drop Stimulation with an Ankle Foot Orthosis (AFO) for Walking

A common assumption may be that fitting an ankle foot orthosis (AFO) is sufficient to address walking difficulty after neurologic impairment such as stroke, MS,  traumatic brain or spinal cord injury. However, patients fitted with an AFO to assist walking can, in many cases, benefit from a foot drop stimulator as this intervention can be […]

FES to assist walking with MS

In some individuals, MS may result in weakness of the lower limb (leg) muscles and difficulty with walking, Decreased walking endurance may also limit ability to walk  even short distances out of doors or in the home. Through its effect in augmenting the force of a muscle contraction and eliciting movement lost due to MS, […]

The Bilateral Effect of FES on Hemiplegic Gait

Slow, inefficient gait with abnormal gait parameters are common findings when assessing walking post stroke. While loss of affected limb foot strike angle is a common finding we may additionally see compensatory change where foot strike angle in the non affected limb is similarly abnormal. Example 2 graph (grey area= normal range)  illustrates the bilateral […]

Assessing with FES: Clinician & Patient Factors

Generation of a motor response to facilitate FES assisted gait in stroke patients may, at times, require clinician “perseverance”. In applying FES for gait -consideration of factors influencing the stimulation response is necessary. Presence of adipose tissue, adjustment of stimulation parameters & electrode positioning all play a part in individual patient motor responses to stimulation. Stimulation parameters […]

Clinical Considerations in Patient Assessment for a Dropped Foot Stimulator

Individuals with a diagnosis of hemiplegia (from stroke or acquired brain injury) or multiple sclerosis or incomplete spinal cord injury can all benefit from FES (functional electrical stimulation) and it should be considered when gait restoration or improvement is a clinical goal. As the presentation of motor loss in stroke vs MS vs SCI is different […]

FES or AFO to improve hemiplegic gait post stroke

  A 2015 study  by Bethoux et al., investigating dropped foot stimulation (DFS) versus an ankle foot orthosis (AFO)  to assist gait post stroke, reported  DFS to be “not inferior “  to an AFO in improving gait components in stroke subjects. (Long-Term Follow-up to  a Randomized Controlled Trial comparing FES ro an AFO for Patients […]

Long term use of dropped foot stimulation in Stroke & MS

  Background: In Great Britain, patients may be funded for Odstock dropped foot stimulators under the UK National Health System. Under this model, patients fitted with Odstock technology undergo re-assessment of their walking at 6 and 12 month intervals. This has enabled collection and analysis of walking data over a 10 year period of dropped […]
