Swedish physician Dr. Gustav Zander helped pioneer “mechanotherapy”. He would further develop these devices, going on to win a gold medal at the 1876 Centennial Exhibition in Philadelphia for his exercise machines.
Movement as a therapeutic agent did already have its proponents—Zander was a follower of the movement cure promoted by an earlier pioneer of exercise Per Henrik Ling.
By the time the edition of his book, Dr. G. Zander’s medico-mechanische Gymnastik was published in 1892, he was well on his way to establishing Zander Institutes across the globe.
By the turn of the century, his machines were in health spas across the country, emblematic of an upscale clientele looking for status symbols to reflect their leisurely lifestyles and exemption from physical labor.

Did you know that students with conditions like autism, ADHD, or dyslexia have unique learning needs?

It's #AutismAcceptanceWeek, and I would like to share some tips on how educators can support neurodivergent students in the classroom.

🧵 Follow the thread.
1) A safe and inclusive learning environment is crucial for neurodivergent students. This can mean providing clear expectations, minimizing distractions, and offering accommodations such as extra time or preferential seating.
2) It's important to remember that all students learn differently, not just the neurodivergent. So, it's essential for educators to use a variety of teaching strategies and materials. Making this a normal part of education can benefit all students, regardless of neurodiversity.

Did you know that in 1962, a mysterious epidemic of uncontrollable laughter broke out in Tanganyika (now Tanzania)?

It became known as the "Laughter Epidemic of Tanganyika" and it's one of the strangest events in medical history.

🧵 Image
The laughter epidemic started in a girls' school and spread rapidly, affecting over 1,000 people in the area. The symptoms included laughing fits, crying, and even fainting. The epidemic lasted for several months and disrupted daily life in the affected areas.
The cause is still unknown, but there are a few theories. Some believe it was caused by 'mass hysteria' or a psychological disorder, while others think it may have been caused by a viral or bacterial infection.

However, no definitive explanation has been found.

On this day in history, March 13, 1925, the Tennessee General Assembly approved a bill prohibiting the teaching of evolution in public schools.

(🧵)
This bill, also known as the Butler Act, made it illegal for public school teachers in Tennessee to teach any theory that denied the biblical account of man's creation.
This law would eventually lead to the famous Scopes Monkey Trial, where a high school teacher named John Scopes was charged with violating the Butler Act by teaching evolution.

In the late 19th century, cocaine was a popular treatment for a variety of medical conditions. It was believed to be a powerful painkiller and was even used as an anesthetic during surgeries.

The famous Sigmund Freud was a proponent of cocaine and used it himself.

(🧵) Image
Patients who received cocaine as a treatment often became addicted to the drug, which could cause a wide range of physical and psychological problems.
In addition to cocaine, doctors in the past also used some other bizarre substances in their medical treatments. For example, leeches were a common treatment for various ailments, as they were believed to draw out "bad blood" from the body.
