Difficulty moving limbs after a stroke can occur for a variety of reasons, but the main one is "motor paralysis."
However, even if the place where the exercise command is issued or the path through which the exercise command is delivered is not damaged, the limbs may become difficult to move.
Even if the brain regions associated with movement are not directly damaged, "sensory disturbances" can be considered to be the cause of difficulty moving the extremities.
Unlike motor paralysis, sensory disturbances are difficult to understand.
This time, I want to write about the effects of sensory impairment.
effect on walking
There are reports investigating the relationship between sensory impairment and walking speed in post-stroke patients with mild paralysis.
In this report, lower extremity sensory disturbances were investigated and classified into four categories: normal, mild, moderate, and severe.
Effects on independent walking
There is a report of post-stroke patients with mild motor paralysis of the lower extremities who were unable to walk independently at the time of hospitalization and investigated the effect on time until independent walking.
He noted that there was a significant correlation between the severity of lower extremity sensory disturbances and time spent walking independently.
In this regard, a previous study by Reding et al also reported that people with motor paralysis with sensory impairment were less likely to be able to walk independently compared to people with motor paralysis alone, and had a longer time until independence. . it's been.
Based on this, we interpret that the complications of post-stroke sensory impairment reduce the efficiency of rehabilitation and therefore require a longer time to achieve independent walking.
Effects on upper extremity motor ability
A report has investigated the relationship between upper limb motor ability and upper limb sensory disturbance in patients with mild motor paralysis after stroke.
As a result, a significant correlation between upper extremity sensory impairment and upper extremity motor capacity was observed.
Previous studies have shown that there is no difference in upper limb motor function between people with superficial sensory impairment and those without disabilities, but those with deep sensory impairment are worse than those with disabilities.
At the end
This time, we summarize the effects of sensory impairment.
It is well known that post-stroke sensory impairment is associated with time to walking independence and ability to move the upper extremities.
Not only motor paralysis, but also sensory disturbances can affect the difficulty of moving the limbs.
I want you to pay attention to how your hands and feet feel during your recovery and exercise.
