A test, called the Functional Test, that evaluates the integrated function of the total upper extremity of an adult hemiparetic patient has been developed. It was used with 82 patients admitted to Rancho Los Amigos Hospital for stroke rehabilitation, together with a battery of six objective test measures. Sequential testing by two examiners demonstrated that the test had interrater reliability. The Functional Test score accounted for 87 percent of the variation in the scores achieved by the patients on the six separate objective measures. This tool integrates the information from these objective assessments and appears to be a valid measure of functional use of the hemiparetic upper extremity. The test can be administered in approximately 30 minutes, can be used in different treatment settings, and provides an accurate and immediate assessment of upper extremity capabilities.
This study used a randomized control group design to investigate the impact of an assistive technology and home modification intervention on function for individuals who are aging with a disability. There were 91 participants with polio, rheumatoid arthritis, cerebral palsy, spinal cord injury, stroke, and other impairments. Outcome data were collected at 12 and 24 months through in-home interviews using the Older Americans Resources and Services Instrument (OARS) and the Functional Independence Measure (FIM), and through monthly telephone contact on the hours of in-home care, hospitalizations, and acquisition of AT. The treatment group received an in-home evaluation of their equipment and home modification needs. All recommended AT and home modifications were provided and paid for in full or in part by the study. The control group received the standard community-available health care. A significant "group by time" interaction for the FIM suggested a slower decline in function for the treatment group over 2 years. Further analyses found that the treatment group was more likely to use equipment to maintain independence vs. personal assistance. This study supports the value of assistive technology for adults aging with a disability and suggests that it be provided earlier in the aging process.
Passive cyclical electrical stimulation was applied during a four-week treatment program to the wrist and finger extensors of 16 hemiplegic patients with flexor spasticity. The study noted the effects of this treatment on the patients' sensation; spasticity; passive range of motion of the wrist, metacarpophalangeal, and proximal interphalangeal joints; and strength in the wrist extensor muscles. Patients were divided into chronic and subacute groups. Both groups received electrical stimulation for three half-hour periods a day, seven days a week, as a substitute for all other range-of-motion techniques. Flexion contractures were prevented in the subacute group of patients at the wrist, metacarpophalangeal, and proximal interphalangeal joints. A statistically and clinically significant increase in wrist extension range occurred in the chronic group that had wrist flexion contractures before the electrical stimulation. Increased extension was noted at the metacarpophalangeal and proximal interphalangeal joints of patients in the chronic group. Those patients with some voluntary wrist extension before the treatment began were able to increase their extension strength during stimulation. No changes in skin sensation were noted and only a general trend in decreasing spasticity was apparent.
