Review
BACKGROUND
Peripherally-induced movement disorders (PIMD) should be considered when involuntary or abnormal movements emerge shortly after an injury to a body part. A close topographic and temporal association between peripheral injury and onset of the movement disorders is crucial to diagnosing PIMD. PIMD is under-recognized and often misdiagnosed as functional movement disorder, although both may co-exist. Given the considerable diagnostic, therapeutic, and psychosocial-legal challenges associated with PIMD, it is crucial to update the clinical and scientific information about this important movement disorder.
METHODS
A comprehensive PubMed search through a broad range of keywords and combinations was performed in February 2023 to identify relevant articles for this narrative review.
RESULTS
The spectrum of the phenomenology of PIMD is broad and it encompasses both hyperkinetic and hypokinetic movements. Hemifacial spasm is probably the most common PIMD. Others include dystonia, tremor, parkinsonism, myoclonus, painful leg moving toe syndrome, tics, polyminimyoclonus, and amputation stump dyskinesia. We also highlight conditions such as neuropathic tremor, pseudoathetosis, and -associated myogenic tremor as examples of PIMD.
DISCUSSION
There is considerable heterogeneity among PIMD in terms of severity and nature of injury, natural course, association with pain, and response to treatment. As some patients may have co-existing functional movement disorder, neurologists should be able to differentiate the two disorders. While the exact pathophysiology remains elusive, aberrant central sensitization after peripheral stimuli and maladaptive plasticity in the sensorimotor cortex, on a background of genetic (two-hit hypothesis) or other predisposition, seem to play a role in the pathogenesis of PIMD.

Review
INTRODUCTION
Phantom limb pain (PLP) is a type of neuropathic pain that affects the territory of an amputated limb or other surgically removed body parts. Between 60% and 90% of amputees suffer from PLP during follow-up. There are a range of therapeutic options for PLP, both pharmacological (gabapentin, amitriptyline, tricyclic antidepressants, etc) and non-pharmacological (transcutaneous electrical nerve stimulation, hypnosis, acupuncture, etc). A widely accepted hypothesis considers PLP to be the consequence of postamputation cortical reorganisation. New treatment approaches, such as mirror therapy (MT), have been developed as a result of Ramachandran's groundbreaking research in the 1990s. This review analyses the current evidence on the efficacy of MT for treating PLP.
DEVELOPMENT
We performed a literature review of publications registered from 2012 to 2017 on the CINAHL, Cochrane, Scopus, and PubMed (including Medline) databases using the descriptors "phantom limb" and "mirror therapy." We identified 115 publications addressing MT in PLP. Of these, 17 (15%) contributed useful information for pooled analysis.
CONCLUSIONS
MT seems to be effective in relieving PLP, reducing the intensity and duration of daily pain episodes. It is a valid, simple, and inexpensive treatment for PLP. The methodological quality of most publications in this field is very limited, highlighting the need for additional, high-quality studies to develop clinical protocols that could maximise the benefits of MT for patients with PLP.

Review
In this review intended for medical staff involved in patient rehabilitation, we provided an overview of the basic methods for managing amputation stumps. After the amputation surgery, it is imperative to optimize the remaining physical abilities of the amputee through rehabilitation processes, including postoperative rehabilitation, desensitization, and continuous application of soft or rigid dressings for pain reduction and shaping of the stump. Depending on the situation, a prosthesis may be worn in the early stage of recovery or an immediate postoperative prosthesis may be applied to promote stump maturation. Subsequently, to maintain the range of motion of the stump and to prevent deformation, the remaining portion of the limb should be positioned to prevent contracture. Continuous exercises should also be performed to improve muscle strength to ensure that the amputee is able to perform activities of daily living, independently. Additionally, clean wound or edema management of the stump is necessary to prevent problems associated with wearing the prosthesis. Our review is expected to contribute to the establishment of basic protocols that will be useful for stump management from the time of completion of amputation surgery to the fitting of a prosthesis to optimize patient recovery.

Meta-Analysis
BACKGROUND
Phantom limb pain (PLP)-pain felt in the amputated limb-is often accompanied by significant suffering. Estimates of the burden of PLP have provided conflicting data. To obtain a robust estimate of the burden of PLP, we gathered and critically appraised the literature on the prevalence and risk factors associated with PLP in people with limb amputations.
METHODS
Articles published between 1980 and July 2019 were identified through a systematic search of the following electronic databases: MEDLINE/PubMed, PsycINFO, PsycArticles, Cumulative Index to Nursing and Allied Health Literature, Africa-Wide Information, Health Source: Nursing/Academic Edition, SCOPUS, Web of Science and Academic Search Premier. Grey literature was searched on databases for preprints. Two reviewers independently conducted the screening of articles, data extraction and risk of bias assessment. The meta-analyses were conducted using the random effects model. A statistically significant level for the analyses was set at p<0.05.
RESULTS
The pooling of all studies demonstrated a prevalence estimate of 64% [95% CI: 60.01-68.05] with high heterogeneity [I2 = 95.95% (95% CI: 95.10-96.60)]. The prevalence of PLP was significantly lower in developing countries compared to developed countries [53.98% vs 66.55%; p = 0.03]. Persistent pre-operative pain, proximal site of amputation, stump pain, lower limb amputation and phantom sensations were identified as risk factors for PLP.
CONCLUSION
This systematic review and meta-analysis estimates that six of every 10 people with an amputation report PLP-a high and important prevalence of PLP. Healthcare professionals ought to be aware of the high rates of PLP and implement strategies to reduce PLP by addressing known risk factors, specifically those identified by the current study.

Review
Amputation of a limb is always perceived as a catastrophe. The principles underlying creation of a stump adapted to modern prosthetic fittings must be fully understood and the patient managed by a multidisciplinary team. In paediatric patients, preserving residual limb length is a crucial point that should be assessed according to the expected growth potential. Advances in prosthetic fittings have led to changes in the overall concept of socket design, which seeks to achieve three objectives: to maximise the weight-bearing surface area, to eliminate friction of the skin on the socket, and to eliminate lever-arm effects. The introduction on the market of new materials has contributed substantially to advances in prosthetic fittings. These advances require the use of new criteria for stump quality and optimisation, which exert a considerable influence on prosthesis function. Prosthetic fitting and specific management of psychological and social problems are provided during an inpatient stay in a physical medicine department, by a team of physicians, other healthcare professionals, social workers, and educators. Three-dimensional imaging and gait analysis provide valuable information.

Review
Limb amputation is one of the oldest known surgical procedures performed for a variety of indications. Little surgical technical improvements have been made since the first procedure, but perioperative and post-operative refinements have occurred over time. Post-amputation pain (PAP) of the stump is a common complication but is an extremely challenging condition to treat. Imaging allows early diagnosis of the underlying cause so that timely intervention is possible to minimize physical disability with its possible psychological and socioeconomic implications. A multidisciplinary approach should be taken involving the rehabilitation medicine team, surgeon, prosthetist, occupational therapist and social workers. Conventional radiographs demonstrate the osseous origin of PAP while high-resolution ultrasound is preferred to assess soft-tissue abnormalities. These are often the first-line investigations. MRI remains as a problem-solving tool when clinical and imaging findings are equivocal. This article aimed to raise a clear understanding of common pathologies expected in the assessment of PAP. A selection of multimodality images from our Specialist Mobility and Rehabilitation Unit are presented so that radiologists are aware of and recognize the spectrum of pathological conditions involving the amputation stump. These include but are not limited to aggressive bone spurs, heterotopic ossification, soft-tissue inflammation (stump bursitis), collection, nervosas, osteomyelitis etc. The role of the radiologist in reaching the diagnosis early is vital so that appropriate treatment can be instituted to limit long-term disability. The panel of authors hopes this article helps readers identify the spectrum of pathological conditions involving the post-amputation stump by recognizing the imaging features of the abnormalities in different imaging modalities.

Review
Amputation is followed by both painful and non-painful phantom phenomena in a large number of amputees. Non-painful phantom sensations rarely pose any clinical problem, but 60-80% of all amputees also experience painful sensations (i.e. phantom pain) located to the missing limb. The severity of phantom pain usually decreases with time, but severe pain persists in 5-10% of patients. Pain in the residual limb (i.e. stump pain) is another consequence of amputation. Both stump and phantom pain can be very difficult to treat. Treatment guidelines used for other neuropathic pain conditions are probably the best approximation, especially for the treatment of stump pain. The aim of the present doctoral thesis was to explore some of the mechanisms underlying pain after amputation. Ten studies were carried out (I-X). My PhD thesis from 1998 dealt with pain before the amputation and showed that preamputation pain increases the risk of phantom pain after amputation (I). A perioperative epidural blockade, however, did not reduce the incidence of pain or abnormal sensory phenomena after amputation (II, III). The importance of sensitization before amputation for the subsequent development of pain is supported by study IV, in which pressure pain thresholds obtained at the limb before amputation were inversely related to stump and phantom pain after 1 week. Afferent input from the periphery is likely to contribute to postamputation pain as sodium channels were upregulated in human neuromas (VI), although neuroma removal did not always alleviate phantom pain (V). Sensitization of neurons in the spinal cord also seems to be involved in pain after amputation as phantom pain was reduced by ketamine, an NMDA-receptor antagonist. Another NMDA-receptor antagonist, memantine, and gabapentin, a drug working by binding to the δ2α-subunit of voltage-gated calcium channels, had no effect on phantom pain (VII-IX). Supraspinal factors are also important for pain after amputation as catastrophizing was associated with phantom pain (X). In conclusion, the present doctoral thesis confirmed and expanded the findings by others that several mechanisms are involved in the development and maintenance of phantom pain. A better understanding of the underlying mechanisms will hopefully lead to improved treatment of pain after amputation in the future.

Aim To investigate the effect of direct epineural electrical stimulation of the nerve on the nature of reparative processes in the bone stump. Methods Three series of experiments were carried out with amputation of the thigh in the middle third and muscle plasty. In the 1st and 2nd experimental series a perineural catheter was brought to the stump of the sciatic nerve, through which mechanical irritation of the nerve was performed for 20 days daily for 20 minutes. In the 2nd series, an electrode was added to the nerve and epineural electrical stimulation was performed daily for 20 days. Animals of the 3rd series served as control. The observation periods were 1, 3, 6 months. Histological research method with filling vessels with ink-gelatin mixture was applied. Results In the 1st series, there was a sharp distortion of the reparative process, which consisted of a violation of microcirculation, changes in shape, resorption of the cortical diaphyseal plate, fractures, deformations. In most experiments of the 2nd series, organotypic stumps were formed with normalization of microcirculation. In the 3rd series, results of the formation of the stump were better than in the 1st, but worse than in the 2nd series. Conclusions Painful nerve irritation after amputation leads to a significant disturbance of microcirculation and reparative regeneration at the end of the bone stump with the development of pathological restructuring of bone tissue. Electrostimulation of the nerve improves microcirculation and reparative regeneration of the bone tissue.

Acroangiodermatitis or Pseudo-Kaposi sarcoma is a rare angioproliferative entity, related to chronic venous insufficiency or certain other vascular anomalies. It is often associated with chronic venous insufficiency, arteriovenous malformation of the legs, chronic renal failure treated with dialysis, paralyzed legs and amputation stumps. We hereby describe a case of 45 year old female presenting with pitting pedal edema, multiple ulcers over bilateral lower limbs with irregular margins with erythema and hyperpigmentation of the surrounding skin. Color Doppler study of bilateral lower limbs was normal. Histopathological examination from one of the lesions showed hyperplastic epidermis, proliferation of capillaries in dermis, hemosiderin deposits and lymphocytic infiltrate. These features thus confirmed the diagnosis of Acroangiodermatitis.
