Pain and psychosocial adjustment to lower limb amputation amongst prosthesis users.
The aim of this study was to investigate associations between post-amputation phantom and residual limb pain and prosthesis satisfaction, activity restriction and psychosocial adjustment to amputation among lower limb prosthesis users. Eighty-nine people with a lower limb amputation completed a postal survey. ⋯ Comparisons of those who experienced residual and/or phantom limb pain in the preceding assessment with those who did not revealed significant differences in prosthesis satisfaction, psychosocial adjustment but not in activity restriction. Overall, it is important for clinicians to ascertain the type and level of pain that the person is experiencing and to separate the experiences of the pain from the experiences of the prosthetic limb.

Clinical TrialBalance control enhancement using sub-sensory stimulation and visual-auditory biofeedback strategies for amputee subjects.
Sub-sensory electrical or mechanical stimulation can enhance the sensitivity of the human somatosensory system to improve the balance control capabilities of elderly. In addition, clinical studies suggest that visual-auditory biofeedback can improve sensory compensation for the elderly. This study hypothesizes that the static balance and gait performance of single leg quiet standing and treadmill walking could be improved for providing proprioceptive neuromuscular facilitation using sub-sensory stimulation and visual-auditory biofeedback in amputee subjects. ⋯ With visual-auditory biofeedback as a cue for heel contact and toe push-off condition during treadmill ambulation, the improvement of four dynamic gait performance measures (Double Support Period, DSP, Constant Time Cadence, CTC, Single Support Period, SSP, and Stance/Swing Ratio, SSR) in amputees was verified. This resulted in 7.89% in DSP (affected side), 5.09% in CTC, 16.67% in SSP (sound side), 45.30% in SSR (sound side), and 40.30% in SSR (affected side) respectively. These findings suggest that sub-threshold electrical stimulation and visual-auditory biofeedback rehabilitation strategies may be effective in compensating sensory loss and improving static balance and dynamic ambulation performance for amputees.

Curve correction effect of rigid spinal orthosis in different recumbent positions in adolescent idiopathic scoliosis (AIS): a pilot MRI study.
In this pilot cross-sectional study, the effectiveness of rigid spinal orthoses in the correction of spinal curvature of 14 patients with moderate adolescent idiopathic scoliosis (AIS) at different recumbent positions (supine, prone, right and left decubitus) was investigated. Using magnetic resonance (MR) imaging and multi-planar reconstruction technique, evaluation of the scoliotic spine in the coronal, sagittal and axial planes and the effect of spinal orthosis on AIS at different recumbent positions was studied. There was significant reduction of coronal Cobb's angle (p < 0.05) with bracing at all four recumbent positions and the maximal reduction was found in the prone position (18% reduction). The sagittal Cobb's angle was only significantly reduced at the supine position while the axial rotation did not change significantly in all positions.

Clinical features and outcomes following bilateral lower limb amputation in Korea.
The objectives of this study were to evaluate the clinical features and outcomes of 43 bilateral lower limb amputees. The clinical features obtained included the causes of amputation, level of amputation, concurrent medical problems, and stump condition. Outcome measures were obtained using the activities of daily living (ADL) index, the Frenchay Activities Index (FAI), and mobility grading with prostheses or wheelchair. ⋯ Using the ADL index and FAI, there was no significant difference in scores according to the level of amputation (p > 0.05), but the scores of community prosthetic ambulators were significantly higher than those of wheelchair ambulators (p < 0.05). Age was found to be negatively correlated with ADL index and FAI scores (r = -0.518 vs. r = -0.550) (p < 0.01). This study concludes that overall independence in ADL after bilateral lower limb amputation improved with young age and prosthetic mobility.

The medical records of 186 patients seeking treatment for landmine injuries in the authors' region between 1993 and 2001 were evaluated. Of these patients 13 died of accompanying complications. Ten (10) patients with general body trauma and upper limb trauma were excluded from the study. ⋯ In crush injuries such as those resulting from landmines, soft tissue, vascular, and neurological assessment must be performed with utmost care. Even so, the desired success in interventions intended to save a limb is complicated by a high infection rate, soft tissue complications, and high revision amputation rates. Therefore, a decision to amputate in the early term based on an accurate preoperative assessment is crucial.
