The great prevalence of traumatic brain injury (TBI) and its high economic costs make reducing TBI-related disability a national health care priority. In our research laboratory, CI therapy has been found to significantly improve upper extremity function for persons with chronic TBI. The results have suggested that persons with TBI are less likely to adhere to critical components of the CI therapy protocol than participants with stroke in other studies. Treatment outcomes have also been more variable. Our findings suggest that some cognitive skills appear related to treatment outcome. In addition, cognitive and behavioral deficits, commonly seen with participants with TBI, challenge the delivery of the standard CI therapy protocol with some persons. We discuss the implications of these neuropsychological factors for CI therapy used for chronic TBI and propose further research to more thoroughly investigate these issues. [ABSTRACT FROM AUTHOR]

Constraint-Induced Movement therapy (CI therapy) is a recognized rehabilitation approach for persons having stroke with mild to moderately severe motor upper extremity deficits. To date, no rehabilitation treatment protocol has been proven effective that addresses both motor performance and spontaneous upper extremity use in the life situation for chronic stroke participants having severe upper extremity impairment with no active finger extension or thumb abduction. This case report describes treatment of a chronic stroke participant with a plegic hand using a CI therapy protocol that combines CI therapy with selected occupational and physical therapy techniques. Treatment consisted of six sessions of adaptive equipment and upper extremity orthotics training followed by a three-week, six-hour daily intervention of CI therapy plus neurodevelopmental treatment. Outcome measures included the Motor Activity Log for very low functioning patients (Grade 5 MAL), upper extremity portion of the Fugl-Meyer Motor Assessment, Graded Wolf Motor Function Test - for very low functioning patients (gWMFT- Grade 5), and Modified Ashworth Scale. The participant showed improvement on each outcome measure with the largest improvement on the Grade 5 MAL. In follow-up, the participant had good retention of his gains in motor performance and use of his more affected arm for real world activities after 3 months; after a one-week brush-up at 3 months, and at one year post-treatment.

Background: Although Constraint-Induced Movement therapy (CIMT) has been deemed efficacious for adults with persistent, mild-to-moderate, post-stroke upper-extremity hemiparesis, CIMT is not available on a widespread clinical basis. Impediments include its cost and travel to multiple therapy appointments. To overcome these barriers, we developed an automated, tele-health form of CIMT., Objective: Determine whether in-home, tele-health CIMT has outcomes as good as in-clinic, face-to-face CIMT in adults ≥1-year post-stroke with mild-to-moderate upper-extremity hemiparesis., Methods: Twenty-four stroke patients with chronic upper-arm extremity hemiparesis were randomly assigned to tele-health CIMT (Tele-AutoCITE) or in-lab CIMT. All received 35 hours of treatment. In the tele-health group, an automated, upper-extremity workstation with built-in sensors and video cameras was set-up in participants' homes. Internet-based audio-visual and data links permitted supervision of treatment by a trainer in the lab., Results: Ten patients in each group completed treatment. All twenty, on average, showed very large improvements immediately afterwards in everyday use of the more-affected arm (mean change on Motor Activity Log Arm Use scale = 2.5 points, p < 0.001, d' = 3.1). After one-year, a large improvement from baseline was still present (mean change = 1.8, p < 0.001, d' = 2). Post-treatment outcomes in the tele-health group were not inferior to those in the in-lab group. Neither were participants' perceptions of satisfaction with and difficulty of the interventions. Although everyday arm use was similar in the two groups after one-year (mean difference = -0.1, 95% CI = -1.3-1.0), reductions in the precision of the estimates of this parameter due to drop-out over follow-up did not permit ruling out that the tele-health group had an inferior long-term outcome., Conclusions: This proof-of-concept study suggests that Tele-AutoCITE produces immediate benefits that are equivalent to those after in-lab CIMT in stroke survivors with chronic upper-arm extremity hemiparesis. Cost savings possible with this tele-health approach remain to be evaluated.

Purpose: To evaluate the efficacy of an expanded form of Constraint-Induced Movement Therapy (eCIMT) that renders CIMT, originally designed for treating mild-to-moderate upper-extremity hemiparesis, suitable for treating severe hemiparesis., Methods: Twenty-one adults ≥1 year after stroke with severe upper-extremity hemiparesis (with little or no capacity to make movements with the more-affected hand) were randomly assigned to eCIMT (n = 10), a placebo-control procedure (n = 4), or usual care (n = 7). The participants who received usual care were crossed over to eCIMT four months after enrollment. The CIMT protocol was altered to include fitting of orthotics and adaptive equipment, selected neurodevelopmental techniques, and electromyography-triggered functional electrical stimulation. Treatment was given for 15 consecutive weekdays with 6 hours of therapy scheduled daily for the immediate eCIMT group and 3.5 hours daily for the cross-over eCIMT group., Results: At post-treatment, the immediate eCIMT group showed significant gains relative to the combination of the control groups on the Grade-4/5 Motor Activity Log (MAL; mean = 1.5 points, P < 0.001, f = 4.2) and a convergent measure, the Canadian Occupational Performance Measure (COPM; mean = 2.3, P = 0.014, f = 1.1; f values ≥0.4 are considered large, on the COPM changes ≥2 are considered clinically meaningful). At 1-year follow-up, the MAL gains in the immediate eCIMT group were only 13% less than at post-treatment. The short and long-term outcomes of the crossover eCIMT group were similar to those of the immediate eCIMT group., Conclusions: This small, randomized controlled trial (RCT) suggests that eCIMT produces a large, meaningful, and persistent improvement in everyday use of the more-affected arm in adults with severe upper-extremity hemiparesis long after stroke. These promising findings warrant confirmation by a large RCT.

Purpose: To examine the relationship between change scores on the log mean Wolf Motor Function Test (lmWMFT) and the intensity of supervised Constraint Induced Movement Therapy (CIMT) in participants with subacute and chronic stroke., Methods: A retrospective analysis of data from 169 EXCITE participants who received CIMT either immediately after randomization or one year later was undertaken. During waking hours, participants wore a restraining mitt on the less affected extremity. The lmWMFT was administered before and after the two week treatment block., Results: Significant relationships were seen between the intensity of training and functional score in the immediate, lower functional group for whom more training in adaptive task practice resulted in poorer outcomes (p=0.01) and in the immediate, higher functioning group for whom more training in repetitive task practice resulted in poorer outcomes (p=0.02). Female participants in the immediate group showed less progress in lmWMFT scores with greater amounts of total training (p=0.01). Functional level, gender, and concordance did not modify any other relationship. Both higher functioning participants who trained within the normal ratio (N=50) and who were exposed to more than the prescribed adaptive task practice (N=11) experienced a significant improvement in the lmWMFT score (p=0.03 and p=0.02, respectively) compared to those higher functioning participants who experienced excessive repetitive task practice., Conclusion: Applying CIMT to a large sample of participants with stroke resulted in directionally inappropriate but significant relationships between intensity and lmWMFT scores in the immediate but not the delayed group. Our data also suggest that functional improvements observed in the EXCITE Trial might be attributable to training components other than the designated ratio of training approaches (adaptive and repetitive task practice).

A new therapeutic approach to rehabilitation of movement after stroke, termed Constraint-Induced (CI) Movement Therapy, has been derived from basic research with monkeys given somatosensory deafferentation. CI consists of a family of therapies; their common element is that they induce stroke patients to greatly increase the use of a more affected upper extremity for many hours a day over a 10-14 consecutive-day period. These therapies have significantly improved quality of movement and substantially increased amount of use of a more affected extremity in the activities of daily living in the life situation. The purpose of this paper is to describe the protocol used by the investigative team that developed the family of CI therapies and examined them as an effective rehabilitation approach.

Patients with neurological disorders present therapists with complex challenges for treatment, including weakness, hypertonicity, voluntary movement deficit, limited range of motion, sensory loss, incoordination, and postural instability. The presence of one or more of these impairments negatively influences these patients by contributing to problems in walking, transferring, and reaching. Aquatic rehabilitation offers a unique, versatile approach to the treatment of these disabilities. This article examines the problems encountered by patients with neurological disorders, general principles guiding neurotreatment, and aquatic neurorehabilitation approaches.

Electrical potentials were measured on the breast and at other sites in 110 women with palpable breast masses. The tumor site was significantly electropositive compared with control sites only when the tumor was a cancer, as determined by a subsequent biopsy; the electrical potentials were not influenced by age or menstrual cycle. The results indicate that, on average, altered electrical potentials detected by a noninvasive measurement on the skin reflect the presence of transformed cells in patients with breast cancer. Previous in vitro studies of breast tissue and breast epithelial cells suggest that the observed effect was due to a change in interstitial K+ concentration that arose from alterations in the activity of K+ channels. Electrical potentials may be suitable for diagnosis of individual patients if refinements are made in the measurement technique.
