I am a big fan of the soft thumb supports. They are so versatile and I use them for a a lot of my patients.
They are great for the spastic hands to help reduce tone of the thumb. By helping relax the thumb, the tone of the whole hand tends to reduce. It is also a great proprioceptive stimulation to increase awareness of the hand and its’ position.
I also use them for the CMC1 arthritic thumbs. Patients love the non-intrusive support which enables them to still fully use their hands.
I mainly use Fabrifoam to make these as it is a comfortable, breathable material. At times, when a more sturdy, longer lasting material is needed, Neoprene is a good option.
