Case ReportsCentral representation of phantom limb phenomenon in amputees studied with single photon emission computerized tomography.
To explore the possible mechanisms of phantom limb discomfort after amputation, three amputees with phantom limb pain were studied. This study examined the change of regional cerebral blood flow using technetium-99m hexamethylpropyleneamine oxime-single photon emission computerized tomography, which was arranged at the time of severe phantom limb discomfort and after the discomfort subsided or was completely relieved. Nine representative transverse slices parallel to the orbitomeatal line were selected for quantification. ⋯ With no comparison group of amputees and because of the small number of cases, it is hard to generalize about cerebrocortical involvement in phantom pain, and it is possible that the findings represent a normal phenomenon seen after 'amputation. Another possibility is that the findings represent increased arousal caused by pain rather than an intrinsic pain pathway. Further study is worthwhile.

Admission balance and outcomes of patients admitted for acute inpatient rehabilitation.
The objective of the study contained herein was to evaluate the clinical use of the Berg Balance Scale in a heterogeneous acute inpatient rehabilitation population and to assess the relationship between balance scores at admission and rehabilitation outcomes, including functional gain and length of stay. This was a prospective study of 45 patients with diagnoses including stroke (n = 15), traumatic brain injury (n = 19), and other impairments (n = 11) who were admitted for acute inpatient rehabilitation. Functional ability was evaluated with the Functional Independence Measure (FIM) instrument, and balance was measured using the 14-item Berg Balance Scale. ⋯ Balance scores collected at admission to inpatient rehabilitation, in whole and in part, were shown to account for moderate amounts of variation in length of stay and the FIM efficiency score. For several of the rehabilitation outcomes, balance scores at admission accounted for more variation than scores on the FIM instrument. These findings suggest that routine assessment of balance at admission to inpatient rehabilitation may enhance the ability to predict rehabilitation outcomes beyond that provided by assessment of functional status alone.

Experimental pressure pain in patients with complex regional pain syndrome, Type I (reflex sympathetic dystrophy).
Research in animals shows that the levels of neuropathic pain expression is genetically associated with a characteristic response profile to sensory stimuli. The aim of the present investigation was to examine if pressure algometry can identify a specific pain sensitivity profile in patients with complex regional pain syndrome, Type I (reflex sympathetic dystrophy), and to distinguish complex regional pain syndromes from other chronic pain dysfunction syndromes. Pressure pain threshold and pain tolerance measured at the sternum in 17 patients with complex regional pain syndrome, Type I (reflex sympathetic dystrophy), were compared with values obtained in 13 patients suffering from other chronic pain dysfunction syndromes and in a control group of 24 pain-free volunteers. ⋯ Regardless of group, women exhibited lower pressure pain tolerance than men. In conclusion, the study contained herein shows a specific pain sensitivity profile to experimental stimuli behavior in young patients with complex regional pain syndrome expressed by a large pressure pain sensitivity range, at a location away from the painful area. However, one single pressure pain measurement over the sternum is insufficient for differentiation of patients with complex regional pain syndrome from those with chronic pain because of intersubject variation.

Sleep disorders are a relatively common occurrence after brain injury. Sleep disturbances often result in a poor daytime performance and a poor individual sense of well-being. Unfortunately, there has been minimal attention paid to this common and often disabling sequela of brain injury. ⋯ This study demonstrates the substantial prevalence of sleep disturbances after brain injury. It underscores the relationship between sleep disorders and perception of fatigue. It also underscores the need for clinicians to strive for interventional studies to look at the treatment of sleep and fatigue problems after brain injury.

Case ReportsBotulinum toxin treatment of lumbrical spasticity: a brief report.
Botulinum toxin A has been used to treat wrist and finger spasticity mainly through injection of the forearm flexor muscles. This case study describes its first reported use in managing spastic lumbricals of the hand. A 19-year-old male had significant flexion deformity and hypertonicity of the left wrist and hand, particularly the second through fifth metacarpophalangeal joints, after traumatic brain injury. ⋯ Botulinum toxin A injection of the lumbricals can be beneficial in managing spasticity of these muscles. It is well tolerated and effective at doses of 10 to 15 units. Lumbrical injection of botulinum toxin A is a useful adjunct in our percutaneous armamentarium for managing the spastic hand.
