Hi! Welcome back.
They have 700M users sending 18 billion messages per week. 28.3% of those messages involve practical guidance like teaching, how-to’s, and health, fitness, and self-care (5.7%).Writing takes the 2nd place with 28.1%. And in the 3th place there’s seeking Information (21.3%).
This shows how people are eager to learn. I would love to know how you use ChatGPT. If you’d like to check the rest of the results, I added the link at the end.
Now, time to check today’s issue.

This study explored whether a soft robotic hand orthosis, RELab tenoexo 2.0 could help stroke survivors improve hand function—first with therapists in a clinic, then by themselves at home.
🔬 Methods
2 phase study: 3 weeks in the clinic and 2 weeks at home.
Participants: 8 adults with chronic hemiparetic stroke (35-69 years old).
9 supervised sessions in clinic performing functional tasks.
At home: 10 sessions x 1 hour unmonitored.
Assessments:
📊 Results
Participants completed 81% of the suggested time and 118% of the suggested sessions.
At-home training showed higher grasp repetitions per hour (150.8 vs. 98.2 in clinic).
Action Research Arm Test: +5.0 points.
Fugl Meyer: +6.0 points.
Improvements were retained after a 1-month.
No significant changes in spasticity and quality of life.
🔑 Key Takeaways
The RELab tenoexo 2.0 robotic glove enabled high-dose, functional hand training. Both in clinical and at-home.
Functional improvements were retained at follow-up.
Home-based therapy did not reduce training quality or quantity.
Quality of life scores did not change significantly, likely due to the short intervention duration.

This study tested whether an AI coaching app could replicate Physiotherapist feedback during lower-limb exercises by comparing joint kinematics and muscle activation in healthy adults.
🔬 Methods
Participants: 11 healthy adults (24.1 ±4.1 years). Each subject performed each exercise 10 times with the left leg.
Physiotherapists.
Merlin Ltd app; a movement tracking appnwith corrective voice feedback
Assesments:
Hip/knee kinematics using an infrared marker system called CodaMotion.
Surface electromyography from 7 hip and knee muscles.
📊 Results
Significant differences in kinematics and muscle activation.
Range-of-motion equivalence: 58% for hip angles and 67% for the knee.
Joint angles and EMG were not equivalent.
The App struggles with multi-planar control.
🔑 Key Takeaways
AI feedback did not consistently match Physiotherapist feedback in muscle activation or joint angles, but showed similar range of motion guidance.
The tracking system misses data that Physiotherapists identify and correct (tactile facilitation).
AI may serve as a supplementary tool between PT sessions to support adherence and technique.
