In a study, “Effects of a dynamic progressive orthotic intervention for chronic hemiplegia: A case series,” published in the November issue of the Journal of Hand Therapy, researchers found that a custom-fitted wrist extension orthosis, used four hours a day, four times a week, over a 12-week period increased passive range of motion (PROM) and reduced resistance to passive movement (RTPM) in individuals who have suffered strokes. The progress made throughout the test period diminished after orthosis usage was stopped, leading the researchers to conclude that this type of dynamic orthotic intervention can be considered an effective treatment.
Studying the effects of the orthosis on six stroke victims, data was based on a weekly measurement of wrist PROM and RTPM, and after discontinuation of the orthoses, data was gathered using the Modified Ashworth Scale, Tardieu Scale of Spasticity, and the electromyographical (EMG) flexor response to extensor stretching.
