OBJECTIVE: To assess the effectiveness of intramuscular neuromuscular electric stimulation (NMES) in reducing poststroke shoulder pain. DESIGN: Multicenter, single-blinded, randomized clinical trial. SETTING: Ambulatory centers of 7 academic rehabilitation centers in the United States. PARTICIPANTS: Volunteer sample of 61 chronic stroke survivors with shoulder pain and subluxation. INTERVENTION: Treatment subjects received intramuscular NMES to the supraspinatus, posterior deltoid, middle deltoid, and trapezius for 6 hours a day for 6 weeks. Control subjects were treated with a cuff-type sling for 6 weeks.Main outcome measure Brief Pain Inventory question 12 (BPI 12), an 11-point numeric rating scale administered in a blinded manner at the end of treatment, and at 3 and 6 months posttreatment. RESULTS: The NMES group exhibited significantly higher proportions of success based on the 3-point or more reduction in BPI 12 success criterion at the end of treatment (65.6% vs 24.1%, P<.01), at 3 months (59.4% vs 20.7%, P<.01), and at 6 months (59.4% vs 27.6%, P<.05). By using the most stringent 'no pain' criterion, the NMES group also exhibited significantly higher proportions of success at the end of treatment (34.4% vs 3.4%, P<.01), at 3 months (34.4% vs 0.0%, P<.001), and at 6 months (34.4% vs 10.3%, P<.05). CONCLUSIONS: Intramuscular NMES reduces poststroke shoulder pain among those with shoulder subluxation and the effect is maintained for at least 6 months posttreatment

OBJECTIVE: To examine the impact of age on health problems related to traumatic brain injury (TBI). DESIGN: Case-control study using a survey instrument. SETTING: Outpatient setting of a large urban tertiary care hospital. PARTICIPANTS: Young and old community dwellers with histories of TBI and control subjects matched for age. INTERVENTION: Structured interview using the Living Life After TBI assessment tool. MAIN OUTCOME MEASURE: Symptom reporting on 52 potential health problems. RESULTS: Individuals with TBI reported significantly more overall health problems than those without TBI. Younger subjects with TBI reported more problems than their nondisabled, age-matched peers with their patterns of sleep as well as with their metabolic/endocrine, neurologic, and musculoskeletal systems. CONCLUSIONS: Older people with TBI were more likely than nondisabled, age-matched peers to report problems with their metabolic/endocrine and neurologic systems. Younger people with TBI were more likely than older people with TBI to report difficulty falling asleep

Constraint-induced movement therapy (CIMT) is a promising approach to promoting recovery of functional arm movement after stroke. However, controlled studies have been limited to persons who sustained strokes at least 1 year before beginning the treatment protocol. This case study documents the neurologic history and motor recovery of a woman whose natural circumstances lend support to the principles of CIMT. The patient sustained a right midpontine vascular infarct and fell simultaneously, fracturing her right humerus. Orthopedic intervention for the fracture mirrored the protocol suggested by proponents of CIMT by immobilizing her right arm. Her significant recovery of left arm use over a 1-year period was more extensive than what would be typically expected after the type of cerebral infarct she incurred. Her case provides the first evidence in the literature that supports the principles of CIMT when it is applied immediately poststroke

Psychopharmacology is rapidly becoming an adjuvant treatment to traditional rehabilitation strategies for patients with stroke or brain injury because it helps to facilitate recovery in a time-efficient manner. Norepinephrine, dopamine, acetylcholine, and serotonin appear to play important roles in recovery from stroke or brain injury. Animal models have shown that blockade of these neurotransmitters inhibits recovery, whereas recovery is promoted by drugs that promote norepinephrine, dopamine, acetylcholine, and serotonin activity. Preliminary evidence from human trials supports these findings. Further study is needed, but expanded use of pharmacologic agents for stroke and brain-injured patients appears imminent

Objective: The frequency of self reported sexual difficulties was examined in a group of 322 individuals with traumatic brain injury (TBI) ($N = 193$ men; 129 women) and contrasted with reports of sexual difficulties in 264 individuals without disability (152 men; 112 women) residing in the community. Physiological, physical, and body images problems impacting sexual functioning were examined individually and then summed into a sexual dysfunction score. Mood, quality of life, health status and presence of an endocrine disorder were examined as predictors of sexual difficulties post TBI. Study design: In this retrospective study, data about sexual difficulties were analyzed separately for men and women with TBI and without disability. ANOVAs with post hoc analysis for continuous variables, chi-square analyses for categorical variables, and ANCOVAs for predictors of sexual difficulties were utilized. Results: When contrasted to individuals without disability, individuals with TBI reported more frequent: (1) physiological difficulties influencing their energy for sex, sex drive, ability to initiate sexual activities and achieve orgasm; (2) physical difficulties influencing body positioning, body movement and sensation, and (3) body image difficulties influencing feelings of attractive and comfort with having a partner view one's body during sexual activity. Additional gender specific TBI findings were observed. In comparison to gender matched groups without disability, men with TBI reported less frequent involvement in sexual activity and relationships, and more frequent difficulties in sustaining an erection; women with TBI reported more frequent difficulties in sexual arousal, pain with sex, masturbation and vaginal lubrication. While groups differed in core demographic variables, age was the only demographic variable that was related to reports of sexual difficulties in individuals with TBI and men without disability. Age at onset and severity of injury were negatively related to reports of sexual difficulties in individuals with TBI. In men with TBI and without disability, the most sensitive predictor of sexual dysfunction was level of depression. For women without disability, an endocrine disorder was the most sensitive predictor of sexual dysfunction. For women with TBI, an endocrine disorder and level depression combined were the most sensitive predictors of sexual difficulties. Conclusion: Individuals post TBI report frequent physiological, physical and body images difficulties which negatively impact sexual activity and interest. For men post TBI, predictors of sexual difficulties included age at interview, age at injury, and having milder injuries, however, depression was the most sensitive predictor of sexual dysfunctions. For women post TBI, predictors of their sexual difficulties included age at injury and having milder injuries, however, depression and an endocrine disorder combined were the most sensitive predictors of sexual dysfunction. Implications of this study include the need for broad-based assessment of sexual dysfunction, and the implementation of treatment studies to enhance sexual functioning post TBI

Mild traumatic brain injury (MTBI) is a common condition, afflicting as many as 1.5 million Americans yearly. Most individuals sustain MTBI as a result of motor vehicle collisions, but it may also occur as a result of falls, physical assault or sporting accidents. Problems related to MTBI include various pain syndromes, cognitive impairments, disorders of affect, cranial nerve dysfunction, and vertigo, arising from injury to the brain, head, or cervical spine. Symptoms are usually transient, although a small percentage of afflicted individuals develop long-lasting problems, often preventing them from leading productive lives. Recognition of these problems as arising from MTBI is difficult due to the frequent lack of abnormal findings on diagnostic tests and failure to identify a history of head trauma. The American Congress of Rehabilitation Medicine has defined MTBI, an important first step in identifying individuals who need treatment. Diagnosis is usually made by directed questions regarding trauma history and careful procurement and interpretation of appropriate tests. Once a diagnosis is made, proper care can be prescribed in order to lead patients toward more productive lives
