CONTEXT: Single-site studies suggest that a 2-week program of constraint-induced movement therapy (CIMT) for patients more than 1 year after stroke who maintain some hand and wrist movement can improve upper extremity function that persists for at least 1 year.

OBJECTIVE: To compare the effects of a 2-week multisite program of CIMT vs usual and customary care on improvement in upper extremity function among patients who had a first stroke within the previous 3 to 9 months.

DESIGN AND ...

BACKGROUND: Constraint-Induced Movement therapy (CI therapy) is shown to reduce disability, increase use of the more affected arm/hand, and promote brain plasticity for individuals with upper extremity hemiparesis post-stroke. Randomized controlled trials consistently demonstrate that CI therapy is superior to other rehabilitation paradigms, yet it is available to only a small minority of the estimated 1.2 million chronic stroke survivors with upper extremity disability. The current ...

In this laboratory we have developed a set of techniques that randomized controlled studies and a multisite randomized controlled trial have shown can substantially reduce the motor deficit of adult patients with mild to severe chronic strokes. Equivalent results have been obtained with adult patients after traumatic brain injury and brain resection. The basic technique, termed Constraint-Induced Movement therapy or CI therapy was derived directly from basic research with monkeys with ...

BACKGROUND: The aim of constraint-induced movement therapy (CIMT) is to promote use of a limb that is functionally impaired after a stroke. In one form of CIMT to treat upper limb impairment, use of the less severely affected arm is restricted for many hours each weekday over 2 consecutive weeks. The EXCITE trial has previously shown the efficacy of this intervention for patients 3-9 months poststroke who were followed-up for the next 12 months. We assessed the retention of improvements ...

The causes underlying phantom limb pain are still unknown. Recent studies on the consequences of nervous system damage in animals and humans reported substantial reorganization of primary somatosensory cortex subsequent to amputation, and one study showed that cortical reorganization is positively correlated with phantom limb pain. This paper examined the hypothesis of a functional relationship between cortical reorganization and phantom limb pain. Neuroelectric source imaging was used ...

To date, single voxel spectroscopy (SVS) is the most commonly used MRS technique. SVS is relatively easy to use and provides automated and immediate access to the resulting spectra. However, it is also limited in spatial coverage. A new and very promising MRS technique allows for whole-brain MR spectroscopic imaging (WB-MRSI) with much improved spatial resolution. Establishing the reproducibility of data obtained using SVS and WB-MRSI is an important first step for using these techniques ...

OBJECTIVE: To investigate the relationship of white matter integrity and path of the corticospinal tract (CST) on arm function before and after constraint-induced (CI) movement therapy in children with hemiparetic cerebral palsy (CP) and adults with chronic stroke.

DESIGN: Study 1 used a multiple-baseline pre-post design. Study 2 was a randomized controlled trial.

SETTING: Outpatient rehabilitation laboratory.

PARTICIPANTS: Study 1 included children with hemiparetic CP (n=10; mean age ± ...

BACKGROUND AND PURPOSE: Injury-induced cortical reorganization is a widely recognized phenomenon. In contrast, there is almost no information on treatment-induced plastic changes in the human brain. The aim of the present study was to evaluate reorganization in the motor cortex of stroke patients that was induced with an efficacious rehabilitation treatment.

METHODS: We used focal transcranial magnetic stimulation to map the cortical motor output area of a hand muscle on both sides in 13 ...

OBJECTIVE: Constraint-Induced Movement (CI) therapy has been found to be a promising treatment for substantially increasing the use of extremities affected by such neurologic injuries as stroke and traumatic brain injury in adults. The purpose of this study was to determine the applicability of this intervention to young children with cerebral palsy.

METHODS: A randomized, controlled clinical trial of pediatric CI therapy in which 18 children with diagnosed hemiparesis associated with ...

BACKGROUND AND PURPOSE: In research on Constraint-Induced Movement (CI) therapy, a structured interview, the Motor Activity Log (MAL), is used to assess how stroke survivors use their more-impaired arm outside the laboratory. This article examines the psychometrics of the 14-item version of this instrument in 2 chronic stroke samples with mild-to-moderate upper-extremity hemiparesis.

METHODS: Participants (n=41) in the first study completed MALs before and after CI therapy or a placebo ...

OBJECTIVE: To examine the reliability of the Wolf Motor Function Test (WMFT) for assessing upper extremity motor function in adults with hemiplegia.

DESIGN: Interrater and test-retest reliability.

SETTING: A clinical research laboratory at a university medical center.

PATIENTS: A sample of convenience of 24 subjects with chronic hemiplegia (onset >1yr), showing moderate motor impairment.

INTERVENTION: The WMFT includes 15 functional tasks. Performances were timed and rated by using a ...

Research from the present laboratory with adult stroke patients showed that structural neuroplastic changes are correlated with clinical improvements due to constraint-induced movement (CI) therapy. This pilot study evaluated whether comparable changes occur in children receiving CI therapy. Ten children (6 boys) with congenital hemiparesis (mean age: 3 years, 3 months) underwent MRI scans 3 weeks before, immediately before, and immediately after receiving 3 weeks of CI therapy. ...

OBJECTIVE: To continue and expand determination of the reliability, validity, and sensitivity to change of the Arm Motor Ability Test (AMAT), an instrument for assessing deficits in activities of daily living (ADL).

DESIGN: The AMAT was administered twice to patients, with an interest interval of either 1 or 2 weeks, by one of two examiners assigned to patients in counterbalanced order. Patients' interest intervals and scores on the arm portion of the Motricity Index was unknown to the ...

ALTHOUGH phantom-limb pain is a frequent consequence of the amputation of an extremity, little is known about its origin1-4. On the basis of the demonstration of substantial plasticity of the somatosensory cortex after amputation5 or somatosensory deafferentation in adult monkeys6, it has been suggested that cortical reorganization could account for some non-painful phantom-limb phenomena in amputees and that cortical reorganization has an adaptive (that is, pain-preventing) ...
