Introduction:
The effectiveness of physical rehabilitation therapies on patients who required prolonged mechanical ventilation and were discharged from the Intensive Care Unit (ICU) with post-COVID-19 neuromuscular weakness is known in the acute period. The objective of this study was to characterize the functional recovery in people hospitalized with post-ICU neuromuscular weakness due to COVID-19 admitted to rehab.
Methods:
Retrospective study which included 42 patients with post-COVID-19 neuromuscular weakness, who were admitted to two tertiary care rehabilitation centers, from April 2020 to April 2022.
Results:
We found statistically significant differences between the functional evaluations of admission and discharge. The Functional Independence Measure improved from 49 [41-57] a 107 [94-119] (p < 0.001). The Berg scale from 4 [1-6] a 47 [36-54] (p < 0.001), the 6-minute test from 0 [0-0] a 254 [167-400] (p < 0.001), and the 10-meter test from 0 [0-0] a 0.83 [0.4-1.2] (p < 0.001). There were no statistically significant differences between the admission and discharge total score of the functional assessments with age and respiratory complexity.
Discussion:
Treatment for functional recovery in a tertiary and long-term center is beneficial for people with severe post-ICU neuromuscular weakness due to COVID-19, even though 43% did not reach the previous level of mobility. Age and respiratory complexity are variables that did not impact the final recovery.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
