Abstract
Advances in medical care has reduced the rate of mortality from strokes, but the incidence of stroke has remained stable while the incidence of ministrokes has increased. Most stroke victims require long-term care, imposing a heavy financial and emotional burden on families while incurring a heavy cost to society. Thus, strokes are a key issue in the context of health care in Taiwan. This paper proposes using VBA (Visual Basic for Applications) to build a system for assessing Brunnstrom stages based on the observation of several obvious rehabilitation features The system calculates features for accelerometer readings, which are then used as input parameters for a fuzzy algorithm to obtain the Brunnstrom action level. Experimental results show the proposed approach effectively assesses Brunnstrom level, and that the approach can be used to assist physical therapists in performing longitudinal assessments of stroke victim progress, thus improving evaluation efficiency.
Highlights
In recent years, the World Health Organization (WHO) has repeatedly issued a “1 in 6” warning referring to the likelihood that 1 in 6 people can expect to suffer a stroke sometime during their lifetime, regardless of age, gender or ethnicity [1]
The errors were concentrated between ST2 and ST4 in Table 5 because the movement of the test subjects differs from that of actual patients, corresponding to a
This paper identifies features for discrete actions and evaluates the low Brunnstrom level due to low stability and angle of action
Summary
The World Health Organization (WHO) has repeatedly issued a “1 in 6” warning referring to the likelihood that 1 in 6 people can expect to suffer a stroke sometime during their lifetime, regardless of age, gender or ethnicity [1]. Between 1954 and 1956, observation of 100 hemiplegia patients was used to divide the recovery process into seven distinct periods, referred to as Brunnstrom Stages [2], but a clear evaluation model was lacking. LaVigne established a clear stage evaluation model based on Brunnstrom’s staging test, and made suggestions for appropriate treatment, and these methods are still used by clinicians today as the basis for diagnosis of degree of hemiplegia [3]. To develop an appropriate rehabilitation strategy, physicians need to first evaluate the current degree of hemiplegia, using methods including the Brunnstrom Approach, the Fugl-Meyer Assessment (FMA) [4] and the
