A study published in the 30 September 2020 online issue of Neurology, the medical journal of the American Academy of Neurology, has found that stroke patients who get professional rehabilitation training through remote video consultations from their residence, may recover their motor skills better than those who do their rehab in person with a therapist at an outpatient rehabilitation facility.
The study also found that remote rehabilitation may also promote greater brain connectivity.
Chuancheng Ren (Zhongshan Hospital, Fudan University, Shanghai, China), the study author, says that because travel and human contact might not be possible due to COVID-19, “it is important to find out if it is safe and effective for stroke patients to recover at home, using video consultations for their therapy.
“Our findings are exciting because they suggest remote rehabilitation programmes may be more effective than in-person rehabilitation in two ways: on the physical level, with greater increases in physical mobility, and on the brain level, with increased functional brain activity.”
The study enrolled 52 people who suffered a stroke with paralysis on one side of their bodies who had their strokes an average of two weeks before the study. Half of those involved were randomly assigned to a home-based telerehabilitation group and the remaining half were assigned to a conventional outpatient group. All the participants did at least 12 weeks of rehab.
For both groups, each session included 60 minutes of occupational and physical therapy, plus 20 minutes of neuromuscular stimulation. All the participants were assessed for both motor function and brain changes at the start of the study, immediately after completion of the rehabilitative sessions and again three months later.
Researchers used a test that measures the recovery of motor skills in the arms and legs after stroke and in order to show meaningful improvement, there needed to be an increase of at least 10 points.
The group rehabilitating remotely scored an average of 11 points higher than they did at the beginning of the study, while the group receiving conventional in-person rehabilitation scored on average 5.3 points higher.
Researchers used resting-state functional imaging to measure changes in the brain and saw that the remote training group increased their resting state brain connectivity compared to the conventional therapy group.
“We believe the convenience of rehabbing at home may have helped study participants stick to their rehabilitation programmes, and that, in turn, may have helped them recover motor skills better than their conventionally treated peers,” Ren said. “Also, the home environment may have given people more opportunities to participate in and learn from real-life family activities.”
A limitation of the study, however, is that there was no control group receiving no rehabilitation training, which would have allowed researchers to estimate the amount of recovery that might occur naturally.
