Slipping whilst mobilising is an important risk factor for falling and injury among patients in hospital. Non-slip socks containing grips on the soles have been suggested to improve foot traction, thus reducing the risk of falls. However, to date, there has been little research to determine whether such products offer improved traction over conventional socks or even compression stockings. This study aimed to compare the slip resistance of two commercially available non-slip socks, one standard sock and one pair of compression stockings using the Wet Pendulum Test at an independent blinded materials testing laboratory.
The first phase of the study involved evaluating slip resistance of each of the three foot conditions on a ramp that increased in angle over time, until a participant slipped. This was done with the participants wearing either the Non-slip socks, standard sock or bare feet. The socks were tested at the highest heel thickness to ensure complete coverage and maximum traction. Each sock was tested in both the left and right foot position. The results were compared to each other, and then against the performance of bare feet in the same condition.
It was found that the non-slip socks had a marginally superior slip resistance to both the compression stocking and bare feet, but that these differences were less than clinically significant. It was also possible that the socks may perform differently in the presence of fluid contaminants, which would have potential clinical implications when it comes to patients with bladder continence and the need for frequent voiding.
The final phase of the study evaluated the performance of the sock after repeated wettings. The test was repeated in both the left and right foot positions, until the sock could no longer hold its shape. The sock was then rinsed thoroughly and allowed to air dry, avoiding heat as this can diminish the elasticity of the grips, thereby decreasing their effectiveness.
As the sock wears, the grips can become loose or fall off completely. This can affect the performance of the sock, and should be monitored regularly for signs that it is time to replace it. The grips can also be damaged by prolonged exposure to harsh detergents, such as chlorine bleach. It is recommended that the socks be washed gently, in cold water, with mild soaps and detergents to maintain the integrity of the grips. It is also advised that the socks be rinsed and dried flat, to avoid creases in the fabric, which may also impact the grip.
It is crucial to read the care instructions on each product carefully. Keeping these socks in good condition will help reduce the risk of slips and injuries. Ultimately, a pair of non-slip grip socks can boost confidence in movement and help break the vicious cycle of fear of falling, loss of independence and subsequent decline in mobility. This is particularly important for seniors and patients in hospitals who are often confined to familiar, but unfamiliar environments that pose many hazards.
