- Stroke affects gait by resulting in diminished strength and inappropriately timed or graded activity
- Exercise therapy by therapist produced statistically significant increase in speed in most cases functional walking capacity was “restricted” before and after treatment. Strength training increasing strength of muscles by providing resistance to contraction didn’t really find favor because of concerns of increasing spasticity and not enough motivation to move from the conventional therapy. Mentally stimulating a person into more intensive during regular training has shown promise. The review indicates a cautious indication of positive effects in case of electrical stimulation. More impact on sub acute patients than chronic patients. Although positive outcome on walking speed is seen the AHA clinical practice guidelines point to insufficient evidence for benefits of FES and recommend to apply FES only for a limited time post-stroke. Biofeedback did not show significant improvement For individuals who could walk independently, treadmill training and more specifically treadmill training with body support showed speed improvement As far as the robotic devices are concerned, the Lokomat driven gait orthosis and Mechanized gait trainer are 2 commercially available devices which improve the repeatability of training, and enable an increase in the extent of training. Despite reported benefits for gait performance, treatment effects on gait speed and especially on functional community walking capacity have not yet been substantiated. A 2008 paper review paper compares Intervention Approaches for gait rehabilitation. Right from simple exercise therapy,
- Not much research into follow up after initial training although I found a paper that used robot (MIT-Manus) experience to provide additional goal-directed sensorimotor activity to standard rehabilitation treatments but for the upper limb. On reevaluating the impaired limb 3 years later, they found further significant decreases in impairment measures. However, there is increasing evidence that the major part of the improvement in motor functions occurs during the first three months, after which it may continue slowly for up to six months.2~ Physiotherapists may still treat some stroke patients for long periods, even after one year, in spite of the fact that the patients make no measurable progress. Considering that no method of gait retraining has shown significant improvement in functional community walking capacity, there is a need to shift focus to assistance during walking to improve gait than retraining.
- Devices which support or correct the function of a limb or torso. There is another class of powered orthoses that are intended to increase human motor abilities over and above normal levels
- University of Tsukuba in Japan
- The idea of using assistance for walking is promising Apart from the drawbacks of electrical stimulation as a method of gait improvement the other drawbacks include Focuses just on ankle dorsiflexsion whereas knee flexion is an important requirement Study conducted only on one person Do not compare walking speed but use motion analysis using the camera and marker method. Cannot be used with water or while driving Costs $5000.
