Symptoms and Signs – Differential Diagnosis of Steppage Gait
A steppage gait is frequently the outcome of footdrop induced by the weakening or paralysis of the pretibial and peroneal muscles, sometimes due to lesions in lower motor neurons. Foot drop is the suspension of the foot with the toes facing downwards, resulting in the toes making contact with the ground when walking. As a compensatory mechanism, the hip undergoes outward rotation and the hip and knee flex in an amplified manner to elevate the progressive leg above the ground. An audible slap is produced when the foot is thrust forward and the toes make contact with the ground initially.
In general, the gait follows a regular rhythm characterised by even steps and a typical upper body posture and arm swing. Pathological walking can manifest as either unilateral or bilateral and can be either permanent or temporary, contingent upon the specific location and kind of the neurological injury.
Histories and Physical Assessment
Commence by inquiring the patient regarding the commencement of the gait and recent alterations in its nature. Does a relative exhibit a comparable walking pattern? Ascertain whether the patient has experienced a traumatic injury to the gluteal region, hip joints, lower extremities, or knee joints. Indicate any past medical conditions, such as diabetes mellitus, polyarteritis nodosa, and alcoholism, that may be linked to polyneuropathy. When obtaining the patient's medical history, make note of if the patient engages in leg crossing when seated, as this could potentially exert pressure on the peroneal nerve.
Examine the patient's calves and feet by inspection and palpation to detect muscular atrophy and wasting. Conduct a sensory deficiency test throughout the whole length of both legs using a pin electrode.
Medical etiology
Guillain-Barré syndrome
Usually seen following the recovery from the initial phase of Guillain-Barré syndrome, steppage gait can manifest as either mild or severe and unilateral or bilateral; it is always a chronic condition. Muscular weakness typically initiates in the lower extremities, spreads to the arms and face within a span of 72 hours, and may advance to complete loss of motor function and respiratory failure. Additional effects consist of footdrop, temporary paresthesia, increased salivation, difficulty swallowing, excessive sweating, rapid heart rate, orthostatic hypotension, and incontinence.
Herniated lumbar disk
Later-stage weakening and atrophy of leg muscles sometimes result in unilateral steppage gait and footdrop. Nevertheless, the most prominent indication is intense lumbar discomfort, which can extend to the gluteal region, lower extremities, and entire feet, typically in one side. Sustained sciatic pain is commonly accompanied by muscular spasms and sensory impairment. Acute paresthesia and fasciculations may manifest.
Multiple sclerosis
.In the regular cycle of recurrent exacerbation and remission of multiple sclerosis, steppage gait and footdrop normally vary in intensity. Neuromuscular weakness, often affecting the lower extremities, can vary from little fatigue to paraparesis accompanied by urine urgency and constipation. Additional symptoms noted are face pain, visual impairments, paresthesia, lack of coordination, and sensory loss in the ankle and toes.
Atrophy of the peroneal muscles
In peroneal muscle atrophy, bilateral steppage gait and footdrop develop gradually. Foot, peroneal, and ankle joints
First to be impacted are the dorsiflexor muscles. Additional first indications and manifestations include paresthesia, asthenia, and spasms in the extremities, accompanied by rigor, edema, and cyanosis. With the disease advancing, all leg muscles weaken and atrophy, accompanied by diminished or nonexistent deep tendon reflexes (DTRs). In due course, atrophy and sensory impairments extended to the hands and arms.
Acute peroneal nerve injury
An abrupt onset of temporary ipsilateral steppage gait is followed by resolution with the relaxation of peroneal nerve pressure. The gait is characterized by footdrop, muscular weakness, and sensory loss especially on the lateral aspect of the calf and foot.
Points of Special Consideration
The patient exhibiting steppage gait may experience considerable fatigue during walking due to the additional exertion required to elevate their feet off the ground. Upon experiencing fatigue, he may inadvertently stub his toes, resulting in a tumble. To mitigate this, assist the patient in identifying his exercise thresholds and motivate him to get sufficient rest. If such is necessary, direct him to a physical therapist for gait retraining and potential use of in-shoe splints or leg braces to ensure proper foot alignment.
Therapeutic Counseling for Patients
Facilitate the patient's identification of his exercise thresholds and motivate him to get sufficient rest. Afford the patient instruction on the proper use of splints and braces.
