Mind harm survivors who expertise foot drop after TBI have difficulties with lifting the entrance portion of their foot. This will likely trigger the toes to tug when strolling, growing the chance of falls.
Whereas foot drop might be related to a number of circumstances, foot drop after TBI is often attributable to a disruption in communication between the areas of the mind chargeable for motion and the muscular tissues concerned in ankle mobility. When the mind can’t ship the suitable alerts to the muscular tissues to elevate the foot, foot drop could happen.
People with foot drop typically expertise problem strolling and safely navigating every day actions. Happily, there are numerous therapy choices obtainable to assist enhance foot drop after TBI. Use the hyperlinks beneath to leap on to any part of this text to study extra.
Causes of Foot Drop After TBI
The movement of ankle dorsiflexion entails lifting the entrance portion of the foot upwards towards the shin. When an harm impacts the flexibility to carry out this movement, people could also be recognized with foot drop. Whereas the most typical reason behind foot drop is nerve accidents, it can be a symptom of underlying muscular or neurological circumstances, resembling a traumatic mind harm.
To be able to carry out voluntary actions, a sign have to be transmitted from the mind by way of the spinal wire and peripheral nerves to the focused muscular tissues. Disrupting this sign at any level could lead to impaired motion. For instance, foot drop most frequently happens when a peripheral nerve harm within the leg disrupts communication between the mind and the leg muscular tissues.
Nonetheless, an harm to areas of the mind related to ankle motion, resembling the first motor cortex, may lead to foot drop. With out the suitable alerts coming from the mind, the muscular tissues related to lifting the foot usually are not instructed when to contract. Moreover, as a result of the mind can’t inform these muscular tissues to counteract the pressure of gravity pulling downward on the toes, foot drop happens.

Though foot drop is often a direct results of a disruption within the mind’s alerts to the focused muscular tissues, it can be attributable to muscle weak spot. As a result of the causes of foot drop could fluctuate, it’s necessary to seek the advice of with one’s physician and acquire an correct analysis.
Indicators of Foot Drop After TBI
One of the vital widespread indicators of foot drop after a mind harm is ankle weak spot. Nonetheless, there are different signs that docs or therapists could search for as a way to make an correct analysis.
Indicators of foot drop after TBI can embrace:
It’s also widespread for people with foot drop to expertise numbness or tingling within the prime of the foot. That is particularly widespread amongst these with a nerve harm or underlying neurological situation.
Influence of Foot Drop on Each day Actions
Difficulties with ankle dorsiflexion resulting from foot drop can affect participation in lots of actions, resembling placing on sneakers, entering into and out of the bathe, and tapping the foot to music. Nonetheless, the shortcoming to carry out ankle dorsiflexion is often most evident when strolling.
To be able to stroll safely and successfully, the heel often hits the bottom earlier than the toes when stepping ahead. If the toes are unable to be raised, they both drag when stepping or hit the bottom first.
To fight this, people could change their gait sample (how they stroll). Many develop a steppage gait, the place they elevate the leg up increased on the hip and knee to maintain the toes from dragging. This will likely virtually make them appear like they’re climbing stairs fairly than strolling on a flat floor. A steppage gait requires extra power and should trigger additional accidents resulting from security issues and overexertion of the hip and again muscular tissues.
People ought to seek the advice of their physician in the event that they expertise any new or recurring signs which may be associated to foot drop. That means, they’ll extra precisely decide the trigger and administer the suitable therapy.
Significance of Neuroplasticity for Restoration
Since foot drop after TBI typically happens on account of impaired communication between the mind and the muscular tissues concerned in lifting the foot, restoring this communication pathway is important for restoration. Happily, the mind has the pure means to rewire itself by strengthening current neural connections and creating new ones by way of a course of generally known as neuroplasticity.
As neural connections are restored, the mind might be able to precisely ship nerve alerts to the affected muscular tissues, enhancing mobility and general operate. To activate neuroplasticity, it’s critical to persistently and repetitively apply focused workouts involving misplaced features. The extra a motion is practiced, the extra the mind will reinforce and strengthen the neural connections required for that operate.
Treating Foot Drop After TBI
Foot drop therapies that optimize neuroplasticity might be a few of the handiest choices. Whereas just a few widespread therapies for foot drop are listed beneath, it’s necessary for people to seek the advice of with their physician and/or therapist for personalised suggestions.
Efficient therapies for foot drop after TBI could embrace:
Foot Drop Workout routines
To revive communication between the mind and the muscular tissues of the leg, it’s important to rewire the mind by way of neuroplasticity to manage dorsiflexion as soon as once more. One of the simplest ways to realize that is by way of regularly training focused workouts, often with the steerage of a bodily therapist.
Even minimal motion is useful and can assist stimulate restoration. In actual fact, people who’re unable to actively dorsiflex their ankle in any respect can enhance foot drop by supporting their foot by way of appropriate motion patterns.
Really useful foot drop workouts could embrace:
Passive ankle dorsiflexion: To finish this passive train, sit in a cushty place and cross one leg over the opposite, in order that the affected foot is straightforward to succeed in. Then, use the fingers to bend the foot up in the direction of the knee and again down.
Assisted toe raises: In a seated place, place the entrance portion of the non-affected foot beneath the affected one. Then, use the stronger foot to elevate the entrance portion of the affected foot, ensuring to all the time preserve each heels on the bottom. Maintain for just a few seconds, then slowly decrease the foot again down.
Damaging toe raises: After regaining some motion within the foot, begin this train by pointing the toes up towards the physique as a lot as doable. Then, as an alternative of shortly letting the foot fall down, slowly decrease the foot again to a impartial place.
Ball lifts: Sit with each ft flat on the ground. Place a tennis ball on the ground and maintain it between the ft. Then, utilizing each ft, bend on the ankle to slowly elevate and decrease the ball.
As mobility improves, strengthening workouts utilizing resistance bands can be added. Along with boosting restoration, preserving the foot and ankle shifting is important for enhancing blood circulate, reducing the chance of contractures, and decreasing the chance of realized non-use.
Useful Electrical Stimulation
Whereas therapeutic workouts are often one of the best ways to advertise neuroplasticity and enhance foot drop after TBI, some survivors could profit from further therapies, resembling useful electrical stimulation (FES). By sending small electrical impulses into the affected muscular tissues of the leg, FES can create a muscle contraction just like what would happen if the mind itself was telling the muscle to interact.
Reactivating these muscular tissues by way of FES encourages mobility and engages neuroplasticity. Ideally, FES must be used along with therapeutic workouts to maximise the probabilities of restoration.
Ankle-Foot Orthotics (AFOs)
As a result of foot drop makes it troublesome to maneuver and stroll safely, therapists typically advocate utilizing an ankle-foot orthotic, or AFO brace. AFOs present help for the foot and ankle to forestall the toes from scuffing the ground when strolling, reducing the chance of falls.
There are lots of forms of AFOs obtainable, together with the Flex AFO just lately developed by Flint Rehab. A bodily therapist generally is a nice useful resource to assist survivors decide which AFO brace is most fitted for his or her wants.
Whereas AFOs might be useful, they don’t encourage restoration by way of neuroplasticity like the opposite therapies listed above. AFOs are thought-about compensatory ways, which assist to make up for misplaced features with out essentially making an attempt to enhance these features. Subsequently, whereas AFOs can assist people stroll extra safely and successfully, they don’t seem to be good long-term replacements for these hoping to enhance their ankle mobility.
It is because all the time utilizing compensatory ways, resembling an AFO brace, can result in realized non-use. When the muscular tissues concerned in lifting the foot are persistently unused resulting from being stabilized by an AFO brace, any remaining operate in these muscular tissues step by step deteriorates till the physique has realized to not use these muscular tissues in any respect.
To fight this, it’s important to take breaks from utilizing the AFO and apply foot drop workouts. This can assist stimulate the mind and activate neuroplasticity to advertise restoration.
Surgical procedure
Extreme instances of foot drop could require surgical interventions. Completely different surgical therapies, resembling nerve transfers and decompressive surgical procedures, can assist enhance dorsiflexion.
Nerve transfers contain taking “donor nerves” from different elements of the physique and utilizing them to attach the ends of the divided or broken nerves. Decompressive surgical procedure is a process that helps relieve strain on the nerves, which may additionally assist enhance dorsiflexion.
These surgical procedures are typically handiest if there’s an harm to the peripheral nerves along with a TBI, as could happen when the leg has additionally sustained trauma on the time of 1’s harm. As a result of surgical interventions are extremely invasive, they need to solely be thought-about when all different therapy choices have been exhausted.
Recovering from Foot Drop After TBI
Foot drop after TBI could make it troublesome to stroll and safely navigate every day actions. The shortcoming to elevate the entrance portion of the foot (dorsiflexion) is attributable to the disruption of alerts between the mind and muscular tissues.
One of the simplest ways to get better from foot drop is to activate neuroplasticity and restore neural connections. This may be achieved by the constant and repetitive apply of focused workouts, each lively and passive.
Nonetheless, many survivors profit from utilizing a number of therapy choices, together with AFO braces, electrical stimulation, and a wide range of workouts. Subsequently, it’s necessary for people to seek the advice of with their physician to acquire an correct analysis and rehabilitation plan.
