Tunisian AI expertise to benefit Africans in need of artificial limbs

  • Dismayed by the lack of affordable prosthetics, Mohamed Dhaouafi created his own range of low-cost artificial hands
  • High cost and limited availability mean just 5 percent of people in the developing world who need prosthetics have artificial limbs 

TUNIS: Mohamed Dhaouafi began researching prosthetics in 2016 as part of a university project. He swiftly realized there was a lack of readily available and affordable prosthetics, with artificial hands costing up to $50,000.

After finishing his studies, Dhaouafi, 28, ran a startup incubator ZETA HUB at a private university to earn an income while continuing his work on prosthetics. He launched CURE Bionics in late 2018, going full time with his Sousse-based startup in 2019.

Having made multiple prototypes to perfect the design of its prosthetics, the five-strong team decided to launch its products commercially in the first half of 2021.

“We want people using our prosthetics to be satisfied and use it in a practical way — we want our patients to be able to rely on our prosthetics and to guarantee they will last,” said Dhaouafi, CURE’s CEO.

“We’re making some final improvements and will then launch a pilot. If that goes well, we’ll quickly launch in Tunisia before expanding abroad. Tunisia is a tough market, so if we succeed here, we can succeed elsewhere.”

In the developing world, only 5 percent of the 40 million people needing prosthetics have artificial limbs due to the high cost and limited availability. Among those who have received them, nearly 70 percent are dissatisfied and 52 percent reject them, a 2019 University of Nebraska study found.

“People generally feel comfortable wearing a prosthetic, but controlling it is very difficult and complicated. Ours are easy to use since they’re very intuitive,” said Dhaouafi.

The lightweight, 3D-printed artificial hands come with different functions depending on the task the patient wants to perform. The brain tells the limbs to move via electric signals transmitted through the nerves, instructing the appropriate muscles to contract or relax.

CURE’s prosthetic hands deploy artificial intelligence (AI) to read these signals via sensors placed on the skin, which means no surgery is necessary to fit them.

“People suffer different traumas in losing their hands. Some were born without hands, so they never experienced what it means to open and close a hand — their muscle signals will be either weak or absent,” said Dhaouafi.

“These differences can be problematic, so the AI algorithm learns and identifies what the muscle signal is about. By using AI, we can reduce the need for doctors and engineers in teaching patients how to use a prosthetic. If they have to intervene with every patient, we cannot scale the product fast. So we made the algorithm smarter.”

CURE’s patients will master the necessary movements through conscious repetition, imprinting them into their subconscious mind so that they can act without thinking — much like how one learns to ride a bike. To help its patients, CURE has developed a virtual reality training program.

“In the virtual environment, they can manipulate the virtual hand like a prosthetic, but in a gamified way to master the exercises while having fun,” Dhaouafi said. “It’s intuitive training. The doctor can provide therapy remotely without the patient having to visit them in person.”

In developing countries, large swathes of the population lack reliable electricity. Consequently, prosthetics users may be unable to recharge the batteries in their artificial limbs, so CURE’s products will come with a solar-powered wireless charger.

“By adding this feature, we can help more people,” said Dhaouafi.

The prosthetic hands come in various predefined sizes, while the socket is fully customizable. They will likely cost between $2,500-3,000, depending on the specific features the patient requests.

Outside Tunisia, CURE will sell its products through third parties that will conduct product measurement, 3D printing, assembly, fitting, and after-sales service.

“That’s the best way for us to scale fast,” Dhaouafi said.

The company is in negotiations with potential partners across Africa, with priority markets including Nigeria, South Africa, Morocco, Egypt, and Angola.

“I visited many of these countries and know people there,” said Dhaouafi, who has participated in non-profit programs in the target markets. “It’s about finding the right partner.”

Israel strikes Yemen Houthis, warns it will ‘hunt’ leaders

“A short while ago... fighter jets struck military targets belonging to the Houthi terrorist regime,” the Israeli military said
It said it also struck military infrastructure in the ports of Hodeida and Ras Issa

JERUSALEM: Israel struck Houthi targets in Yemen on Friday, including a power station and coastal ports, in response to missile and drone launches, and warned it would hunt down the group’s leaders.
“A short while ago... fighter jets struck military targets belonging to the Houthi terrorist regime on the western coast and inland Yemen,” the Israeli military said in a statement.
It said the strikes were carried out in retaliation for Houthi missile and drone launches into Israel.
The statement said the targets included “military infrastructure sites in the Hizaz power station, which serves as a central source of energy” for the Houthis.
It said it also struck military infrastructure in the ports of Hodeida and Ras Issa.
Israeli Prime Minister Benjamin Netanyahu, in a statement after the strikes, said the Houthis were being punished for their repeated attacks on his country.
“As we promised, the Houthis are paying, and they will continue to pay, a heavy price for their aggression against us,” he said.
Israeli Defense Minister Israel Katz said Israel would “hunt down the leaders of the Houthi terror organization.”
“The Hodeida port is paralyzed, and the Ras Issa port is on fire — there will be no immunity for anyone,” he said in a video statement.
The Houthis, who control Sanaa, have fired missiles and drones toward Israel since war broke out in Gaza in October 2023.
They describe the attacks as acts of solidarity with Gazans.
The Iran-backed rebels have also targeted ships in the Red Sea and Gulf of Aden, prompting retaliatory strikes by the United States and, on occasion, Britain.
Israel has also struck Houthi targets in Yemen, including in the capital.
Since the Gaza war began, the Houthis have launched about 40 surface-to-surface missiles toward Israel, most of which were intercepted, the Israeli army says.
The military has also reported the launch of about 320 drones, with more than 100 intercepted by Israeli air defenses.

Gaza war death toll could be 40 percent higher, says study

Gaza war death toll could be 40 percent higher, says study

  • Researchers sought to assess the death toll from Israel’s air and ground campaign in Gaza between October 2023 and the end of June 2024
  • They estimated 64,260 deaths due to traumatic injury during this period, about 41 percent higher than the official Palestinian Health Ministry count

LONDON: An official Palestinian tally of direct deaths in the Israel-Hamas war likely undercounted the number of casualties by around 40 percent in the first nine months of the war as the Gaza Strip’s health care infrastructure unraveled, according to a study published on Thursday.
The peer-reviewed statistical analysis published in The Lancet journal was conducted by academics at the London School of Hygiene and Tropical Medicine, Yale University and other institutions.
Using a statistical method called capture-recapture analysis, the researchers sought to assess the death toll from Israel’s air and ground campaign in Gaza between October 2023 and the end of June 2024.
They estimated 64,260 deaths due to traumatic injury during this period, about 41 percent higher than the official Palestinian Health Ministry count. The study said 59.1 percent were women, children and people over the age of 65. It did not provide an estimate of Palestinian combatants among the dead.
More than 46,000 people have been killed in the Gaza war, according to Palestinian health officials, from a pre-war population of around 2.1 million.
A senior Israeli official, commenting on the study, said Israel’s armed forces went to great lengths to avoid civilian casualties.
“No other army in the world has ever taken such wide-ranging measures,” the official said.
“These include providing advance warning to civilians to evacuate, safe zones and taking any and all measures to prevent harm to civilians. The figures provided in this report do not reflect the situation on the ground.”
The war began on Oct. 7 after Hamas gunmen stormed across the border with Israel, killing 1,200 people and taking more than 250 hostages, according to Israeli tallies.
The Lancet study said the Palestinian health ministry’s capacity for maintaining electronic death records had previously proven reliable, but deteriorated under Israel’s military campaign, which has included raids on hospitals and other health care facilities and disruptions to digital communications.
Israel accuses Hamas of using hospitals as cover for its operations, which the militant group denies.

STUDY METHOD EMPLOYED IN OTHER CONFLICTS
Anecdotal reports suggested that a significant number of dead remained buried in the rubble of destroyed buildings and were therefore not included in some tallies.
To better account for such gaps, the Lancet study employed a method used to evaluate deaths in other conflict zones, including Kosovo and Sudan.
Using data from at least two independent sources, researchers look for individuals who appear on multiple lists of those killed. Less overlap between lists suggests more deaths have gone unrecorded, information that can be used to estimate the full number of deaths.
For the Gaza study, researchers compared the official Palestinian Health Ministry death count, which in the first months of war was based entirely on bodies that arrived in hospitals but later came to include other methods; an online survey distributed by the health ministry to Palestinians inside and outside the Gaza Strip, who were asked to provide data on Palestinian ID numbers, names, age at death, sex, location of death, and reporting source; and obituaries posted on social media.
“Our research reveals a stark reality: the true scale of traumatic injury deaths in Gaza is higher than reported,” lead author Zeina Jamaluddine told Reuters.
Dr. Paul Spiegel, director of the Center for Humanitarian Health at the Johns Hopkins Bloomberg School of Public Health, told Reuters that the statistical methods deployed in the study provide a more complete estimate of the death toll in the war.
The study focused solely on deaths caused by traumatic injuries though, he said.
Deaths caused from indirect effects of conflict, such as disrupted health services and poor water and sanitation, often cause high excess deaths, said Spiegel, who co-authored a study last year that projected thousands of deaths due to the public health crisis spawned by the war.
The Palestinian Central Bureau of Statistics (PCBS) estimates that, on top of the official death toll, around another 11,000 Palestinians are missing and presumed dead.
In total, PCBS said, citing Palestinian Health Ministry numbers, the population of Gaza has fallen 6 percent since the start of the war, as about 100,000 Palestinians have also left the enclave.

Syria monitor says Assad loyalist ‘executed’ in public

  • The Syrian Observatory for Human Rights said fighters affiliated with the country’s new rulers executed Mazen Kneneh on Friday morning
  • Fighters shot Kneneh in the head on the street in Dummar

BEIRUT: A Syria monitor said fighters linked to the Islamist-led transitional administration publicly executed a local official on Friday, accusing him of having been an informant under ousted president Bashar Assad.
Contacted by AFP, the Damascus authorities did not immediately reply to a request for comment.
The Syrian Observatory for Human Rights said fighters affiliated with the country’s new rulers executed Mazen Kneneh on Friday morning, describing him as “one of the best-known loyalists of the former regime.”
Fighters shot Kneneh in the head on the street in Dummar, a suburb of the capital Damascus, said the Britain-based monitor.
It said he was “accused of writing malicious security reports that led to the persecution and jailing of many young men” who were tortured in prison under Assad, whose rule came to an end on December 8.
A video circulating online, which AFP was unable to independently verify, purportedly showed the man’s slumped body tied to a tree trunk, his clothes bloodied from what looked like a bullet wound to the head.
Members of the public including children gathered around the body, according to the video, some filming with their mobile phones and others beating the body with sticks or high-kicking it in the head.
In recent days, Syrian authorities launched security sweeps targeting “remnants of the regime” of the deposed leader in several areas.
Anas Khattab, the new General Intelligence chief, has pledged to overhaul the security apparatus, denouncing “the injustice and tyranny of the former regime, whose agencies sowed corruption and inflicted suffering on the people.”

Lebanon PM to visit new Damascus ruler on Saturday

  • Lebanon’s Prime Minister Najib Mikati will on Saturday make his first official trip to neighboring Syria since the fall of president Bashar Assad, his office told AFP

BERUIT: Lebanon’s Prime Minister Najib Mikati will on Saturday make his first official trip to neighboring Syria since the fall of president Bashar Assad, his office told AFP.
Mikati’s office said Friday the trip came at the invitation of the country’s new de facto leader Ahmed Al-Sharaa during a phone call last week.
Syria imposed new restrictions on the entry of Lebanese citizens last week, two security sources have told AFP, following what the Lebanese army said was a border skirmish with unnamed armed Syrians.
Lebanese nationals had previously been allowed into Syria without a visa, using just their passport or ID card.
Lebanon’s eastern border is porous and known for smuggling.
Lebanese Shiite group Hezbollah supported Assad with fighters during Syria’s civil war.
But the Iran-backed movement has been weakened after a war with Israel killed its long-time leader and Islamist-led rebels seized Damascus last month.
Lebanese lawmakers elected the country’s army chief Joseph Aoun as president on Thursday, ending a vacancy of more than two years that critics blamed on Hezbollah.
For three decades under the Assad clan, Syria was the dominant power in Lebanon after intervening in its 1975-1990 civil war.
Syria eventually withdrew its troops in 2005 under international pressure after the assassination of Lebanese ex-prime minister Rafic Hariri.
