Ergonomic - Scientifically designed to increase comfort & ease of use, reduce injury or pain
Superior function - a universally great tool
These lightweight ergonomic grips were first recommended to us by our design team member Angela Hissong, an occupational therapist who works extensively with farmers through the AgrAbility program. There are two types of grips, the D-grip and the T-grip, both of which make most hand tools safer and easier to work with. You can simply attach them to garden hoes, spades, rakes, brooms, vacuums, snow shovels and more.
The D-grip mounts mid-way down the garden tool handle and gives lifting leverage to the forward hand. The T-grip mounts at the upper end of the garden tool handle and gives pushing and pulling control to the back hand. Both grips were designed to offer arthritis and back pain relief and reduce the risk of repetitive strain injuries including Carpal Tunnel Syndrome and tendonitis.
Through its research, GHTs has identified 4 factors that influence lower back disorders: heavy physical work, lifting and forceful movements, bending and twisting (awkward postures) and lastly, whole-body vibration (Fathallah et al., 2004).
The Motus grips influence the first three of these risk factors. Their impact on the 3 factors was studied by Kean Kriellaars, PhD., University of Manitoba, School of Medical Rehabilitation with the following summary results of his evaluation of the grips:
- permits the wrist angle to remain in a near neutral position, which is beneficial to structures in and about the wrist
- enables the user to incorporate larger trunk and lower limb musculature
- decreases the likelihood of tendonitis of the intrinsic shoulder muscles
- permits remaining in a more upright position during a lifting task, producing substantial energy savings and possibly resulting in less cumulative trauma
- reduces by 10% the load arising from the decrease in trunk angle and the closer load carrying (this is beneficial for prevention and rehabilitation of lower back injuries)
- reduces the potential for blister formation

The three risk factors for lower back injuries -- lifting, pushing and pulling, and twisting -- are impacted by the use of Motus grips.
Lifting is involved in the use of garden spades, shovels, and pitch forks. These grips are truly ergonomic because they are based on scientific principles and evidence. Biomechanically, lifting involves the body as a "third class lever". Adding the D-grip mid-way down the shovel handle moves the fulcrum to the lower hand, transferring the effort to the long end of the shovel, making it a "first class lever". With increased leverage the user may now lift a heavier load with greater ease.
Pushing and pulling is involved in the use of garden rakes, hoes and push brooms. Adding the D-grip mid-way down the garden tool handle improves posture by allowing the user to stand taller with less back bend Limb alignment and hand position with the D-grip are more neutral, reducing the risk of repetitive stress injury and Carpal Tunnel Syndrome.
Twisting is involved in the use of garden leaf rakes, scythes, some hoes and sweep brooms. Adding the T-grip midway down the garden tool handle as well as at the upper end allows a greater range of motion. A straight line force from the shoulder to the grip opens the space between the shoulders for good posture and reduces the risk of back and muscle strain. Neutral limb alignment and hand position help reduce arthritis and back pain.
Motus T-grip Reviews
We asked participants at a PA Women’s Agricultural Network field day to try these grips, and we’ve also used them in trials of our shovel, HERS™ Almost unanimously, testers have responded enthusiastically to the auxiliary handles. At the PA WAgN field day, for example, 11 out of 12 participants who tried the D-grip on a shovel said the grip helped very much or somewhat in use of the shovel. Although the T-grip was not formally evaluated, all of the participants who tried it on a hoe said they liked it. According to one male participant, the auxiliary handles "rock." Similarly, participants in our formal prototype trials found the D-handle helpful in reducing back strain in transferring material.
Concerns identified by researcher and GHT:
The T-grip was found to loosen or tighten somewhat with variations in temperature so the user should check that the grip is secure before each use. GHT did tighten the grips before each use. GHT notes that since the grips are plastic, we suspect that they may not have longevity, but we perceive that the benefits -- injury prevention, increased ease of many of the tasks done by women in agriculture and gardening, and reasonable cost – far outweigh any concerns about the material. Although you can easily transfer the grips from one tool to another their reasonable cost would permit you to place one on each tool and save time in the long term.
