Improved grip strength and hand function demonstrated in preliminary data from the iHand study

Today, preliminary results from the ongoing iHand study were presented at the congress of the International Federation of Hand Surgery and Hand Therapy (IFSSH & IFSHT) in London. The results from 49 participants show a significant improvement in both grip strength (27%) and hand function (12%)*. These preliminary results are valuable since they indicate that people with reduced grip strength and hand function can independently perform activities in daily life with Carbonhand®.

For people with impaired hand function, the ability to perform activities of daily living (ADL) is often impaired and a limiting factor in their lives. One of the biggest problems in number of disabilities is a reduced grip strength, which leads to them having difficulty grasping and holding objects, which in turn can negatively affect their quality of life.

The power-strengthening glove Carbonhand gives patients an improved grip during use. The hypothesis in the study is that long-term use of Carbonhand on the affected hand provides intensive and task-specific training, which results in improved arm and hand function even without support of the glove. That is, the use of the glove has a so-called rehabilitative effect.

In the ongoing iHand study conducted at eight different clinics in the Netherlands, patients, who have lived with a disability in the hand for an average of 10 years, have used Carbonhand for six weeks and then evaluated the effect of the glove. When data from 49 participants have been analyzed, an improvement in hand strength of 27% is seen immediately after the intervention period. In order to demonstrate a rehabilitative effect, the grip strength has also been measured four weeks after the use of Carbonhand has ended, also with very good results. The remaining improvement in grip strength is 24%.

The Jebsen-Taylor Hand Function Test, a standardized assessment of hand function, has also been used to assess how well participants can perform a simulation of daily activities. In this test, participants are asked to perform seven different tasks and, in these assessments, participants have improved their function by 12%.

"The fact that Carbonhand improves grip function by 27% in patients who received their injury on average 10 years ago is impressive, it means great opportunities for thousands of patients to regain their lost hand function and improve the quality of life significantly. We are now looking forward with great excitement to a new version of Carbonhand being released on the market soon to further improve the situation for those living with impaired hand function.” -says Petter Bäckgren, CEO of Bioservo.
