The shoulder-hand syndrome after stroke: clinical factors of severity and value of prognostic score of Perrigot]

PURPOSE: The purposes of this study were to evaluate the prognostical factors of reflex sympathetic dystrophy in stroke patients in attempt to improve the Perrigot prognostical score. MATERIAL AND METHOD: This prospective study included 28 stroke patients with reflex sympathetic dystrophy. An initial clinical assessment including Perrigot score was made at the time of admission (before the end of the first month) and a second evaluation of reflex sympathetic dystrophy at the end of the third month. Patients were assessed using Motricity Index, Ashworth scale, de Bats grading (for glenohumeral alignment), Labrousse criteria (for reflex sympathetic dystrophy severity), and MADRS depression scale. Sensory deficit and unilateral neglect were noted. RESULTS: The length of stay in acute ward was 16 days. The Perrigot score was correlated with the reflex sympathetic dystrophy severity (r = 0.7, p < 0.0001). It predicted the result of therapy. A significant correlation was found between reflex sympathetic dystrophy severity and motor deficit (r = -0.591, p = 0.0007) and spasticity (p < 0.05). No relation was found with stroke side, unilateral neglect, depression or shoulder subluxation. It wasn't possible to improve the Perrigot prognostical score. CONCLUSION: Perrigot score predict reflex sympathetic dystrophy severity and the result of therapy. The shoulder subluxation which is not included in this score appears to be not predictive. Shoulder subluxation is simply a marker of a severe paresis.     

Clinical factors associate with shoulder subluxation in stroke patients]

OBJECTIVE: This study explores whether shoulder subluxation after stroke is related to age, hemiplegic side motor impairment, spasticity, sensory deficit, depression, unilateral neglect and length of stay in acute ward. METHOD: This prospective study included 57 patients with hemiplegia. The shoulder subluxation was systematically detected by radiography and quantified according to de Bats score. The complete clinical assessment of the upper limb on day 15 analyzed motricity (motricity index), spasticity of shoulder adductors and biceps (Ashworth), sensory deficit, unilateral neglect and depression (MADRS). Age, side of hemiplegia and the aetiology were also noted. We researched relations between shoulder subluxation and these clinical factors. Means were compared using Mann Whitney and chi(2) tests. Coefficients of correlation were estimated between two quantitative variables. A multiple regression analysis was also conducted including all significant parameters, the dependent variable being the shoulder subluxation. RESULTS: Shoulder subluxation was observed in 32% of hemiplegic patients. After multiple regression analysis, the main clinical factors related to subluxation were motor (p < 0.0001), spasticity of shoulder adductors (p = 0.028) and age (p = 0.036). Statistically, the risk of subluxation was divided by 1.62 (1.07, 2.43) for every five years age growth and by two (1.33, 2.94) when the motricity index went up by ten points. CONCLUSION: This study shows that the age could play an independent part. The loss of elasticity of the periarticular tissues when ageing could have a protective role.     

Early prediction of functional outcome one year after initial unilateral hemispheric stroke]

BACKGROUND AND PURPOSE: Several prognostic factors have been identified for outcome after stroke. We conducted a study to determine early predictive factors of functional outcome one year after stroke and to evaluate which factors are independent predictors, with an aim of specifying the role of age, aphasia, unilateral neglect, cognitive impairment and family social support. METHODS: Observational cohort study of 156 patients. All patients admitted to the university hospital for initial unilateral hemispheric stroke were included. The study duration was two years (inclusion, one year, and follow-up, one year) .The initial evaluation of stroke was conducted at day 2 and day 15 and included the Motricity Index and Trunk Control Test, New Functional Ambulation Classification, Frenchay arm test, Mini-Mental State Examination, Boston Diagnostic Aphasia Examination, unilateral neglect evaluation, and depression. Data on functional recovery (Barthel Index) were collected at day 360. RESULTS: The average age of patients was 72 years. Age was correlated to social situation (P<0.01) and previous neurological impairment (P<0.01). A multiple regression analysis, including 14 initial clinical factors correlated with the Barthel Index score at day 360, revealed 4 independent early predictive factors of outcome: initial score of Barthel Index at day 2 and its progression from day 2 to day 15, disorders of the executive functions and previous neurological impairment. CONCLUSION: In our cohort, in accordance with previous studies, age, cognitive impairment, unilateral neglect, aphasia, depression and social situation are not independent factors of poor outcome after stroke as evaluated by the Barthel Index.     

Cognitive correlates of "neglect-like syndrome" in patients with complex regional pain syndrome

Patients with complex regional pain syndrome (CRPS) often show distinct neurocognitive dysfunctions, which were initially termed "neglect-like symptoms." So far, particularly the patients' feelings about the affected extremity, motor, and sensory aspects of the "neglect-like symptoms" have been investigated, possibly pointing to a disturbed body schema. Because patients with classical neurological neglect show diminished awareness regarding the perception of their body, as well as of the space around them, our hypothesis was that CRPS patients exhibit some signs of personal neglect and extrapersonal visuospatial problems over and beyond those seen in patients simply suffering from limb pain. We used quantitative sensory testing and motor assessment aimed at detecting motor and sensory loss, a standardized questionnaire calculating a neglect score, and applied a detailed neuropsychological test battery assessing different parietal lobe functions, including visual neglect. We examined 20 CRPS patients and 2 matched control groups, one consisting of healthy subjects and the other one of patients with limb pain other than CRPS. Results show significant higher neglect scores for CRPS patients and the pain control group, but interestingly, CRPS patients and pain patients were indistinguishable. The results of the neuropsychological test battery did not demonstrate systematic variances, which would be indicative of a classical neurological neglect in CRPS patients, even though there were 3 CRPS patients who differed ≥ 2 SD from the mean of our healthy control group, with poorer results in ≥ 3 different tests. We assume that the "neglect-like syndrome" in most CRPS patients is different from typical neglect.     

Neglect-like symptoms in complex regional pain syndrome: results of a self-administered survey.

Reflex sympathetic dystrophy (RSD), recently reclassified as a complex regional pain syndrome, type I (CRPS-I), is best known for its disabling sensory symptoms, including pain, allodynia, and abnormal skin temperature. Yet, motor dysfunction is common in CRPS and can result in major disability. In addition to weakness of the involved limb, CRPS patients may develop symptoms akin to a neurological neglect-like syndrome, whereby the limb may feel foreign ("cognitive neglect") and directed mental and visual attention is needed to move the limb ("motor neglect"). Members of the patient support group, the Reflex Sympathetic Dystrophy Syndrome Association (RSDSA), were mailed a questionnaire inserted in their newsletter which inquired about the presence of these neglect-like symptoms; in addition, a separate medical history questionnaire was included to assess adequate documentation for the diagnosis of CRPS. A total of 242 patients returned the questionnaire but only 224 of the questionnaires were analyzed; 15 were excluded due to inadequate documentation of CRPS and 3 were excluded due to non-limb involvement. Eighty-four percent (84%) of these respondents endorsed the presence of at least one neglect symptom and 47% indicated they had both "cognitive" and "motor" neglect symptoms. Of interest, approximately 33% of respondents spontaneously wrote comments regarding the significant disability due to these neglect symptoms and the difficulty explaining these unusual symptoms to their health care providers and family. This patient survey confirms the presence of neglect-like symptoms in a subset of CRPS patients. Neglect-like symptoms need to be addressed and validated by health care providers.     

Comparison of prednisolone with piroxicam in complex regional pain syndrome following stroke: a randomized controlled trial

BACKGROUND: Complex regional pain syndrome (CRPS) following stroke aggravates morbidity. CRPS is categorized as CRPSI when no clear nerve injury is defined, and CRPSII when associated with clear nerve injury. AIM: To compare the effect of prednisolone with that of piroxicam in patients with CRPSI following stroke. DESIGN: Randomized controlled trial. METHODS: Patients with CRPSI fulfilling the inclusion criteria (n = 60) underwent a detailed neurological examination, cranial CT scan, radiograph of chest and shoulder joint, blood counts and serum chemistry. Severity of stroke was assessed by the Canadian Neurological Scale (CNS), CRPS by scoring sensory, autonomic and motor symptoms, and activity of daily living by Barthel index (BI) score. Patients were randomly assigned prednisolone 40 mg or piroxicam 20 mg daily, and outcome was assessed at 1 month on the basis of CRPS and BI score. RESULTS: Mean patient age was 56 years and 20 were female. Baseline clinical and radiological parameters were comparable between the two groups. In the prednisolone group, 83.3% patients showed significant improvement, compared to 16.7% in the piroxicam group. The mean change in CRPS score in prednisolone group was 6.47 (95%CI 4.37-7.36), whereas in piroxicam group it was only 0.47. The mean change in BI score was 7.9 (95%CI 0.82-5.98) in the prednisolone group, and 4.5 in the piroxicam group. DISCUSSION: In this patient group, prednisolone resulted in significant improvement in the symptoms and signs of CRPSI following stroke, compared to piroxicam. Both drugs produced an improvement in the BI score.     

Poststroke shoulder pain: a prospective study of the association and risk factors in 152 patients from a consecutive cohort of 205 patients presenting with stroke.

BACKGROUND AND PURPOSE: Shoulder pain is known to retard rehabilitation after stroke. Its causes and prognosis are uncertain. This study describes the incidence of poststroke shoulder pain prospectively, in an unselected stroke population in the first 6 months after stroke and identifies risk factors for developing pain. METHODS: 297 patients with possible stroke were screened and stroke diagnosed in 205 cases. The 152 patients entered the study of which 123 patients were assessed up to 6 months. This cohort, with a mean age of 70.6 years, was examined at 2 weeks, 2, 4, and 6 months. A history of shoulder pain, Barthel score, anxiety and depression score were recorded. Full neurological and rheumatological examination was undertaken, using the contralateral side as a control. Pain outcome and stroke outcome was recorded at subsequent visits. RESULTS: 52 (40%) patients developed shoulder pain on the same side of their stroke. There was a strong association between pain and abnormal shoulder joint examination, ipsilateral sensory abnormalities and arm weakness. Shoulder pain had resolved or improved at 6 months in 41 (80%) of the patients with standard current treatment. CONCLUSIONS: Shoulder pain after stroke occurred in 40% of 123 patients surviving, consenting and not too unwell to participate. This included 52 patients of an original cohort of 205 patients presenting with stroke. Eighty percent of patients made a good recovery with standard treatment Patients with sensory and or motor deficits represent at risk sub-groups.     

Assessment of peripheral sympathetic nervous function for diagnosing early post-traumatic complex regional pain syndrome type I

Clinical diagnosis of complex regional pain syndrome type I (CRPS I) in post-traumatic patients is often delayed since the clinical appearance of this disease resembles normal post-traumatic states to a certain extent (pain, edema, loss of function). The purpose of this study was to assess the incidence of specific clinical features in CRPS I patients and normal post-traumatic patients and to evaluate the diagnostic value of a bedside test that measures the sympathetic nervous function. Fifty patients with post-traumatic CRPS I of the upper limb and 50 patients 8 weeks after distal radius fracture with an undisturbed course of disease were subjected to a detailed clinical examination. Pain was assessed using the VAS (visual analog scale), skin temperature measured with an infrared camera and grip-strength with a pneumatic manometer. In CRPS I patients, motor disturbances defined as an impaired active range of motion of the hand, were most frequent (96%, fracture patients: 40%), followed by edema (88%, fracture patients: 80%) and spontaneous pain (VAS 4.0 +/- 2.3, fracture patients: VAS 1.3 +/- 0.6). Systematic temperature differences (>1 degree C) between the affected and unaffected limbs were seen in only 42% of CRPS I patients and in 34% of the fracture patients. Further sensory, sudomotor or trophic changes of the hands were rare. As expected, there were significant differences in the quantity of edema, motor disturbances and sensory disturbances between CRPS I patients and normal fracture patients. However, normal fracture patients still suffered from several of the evaluated symptoms 8 weeks after trauma, which makes an early clinical diagnosis of the complication more difficult. Using a newly developed bedside test, the peripheral sympathetic nervous function was assessed in both groups of patients and in 50 age-matched healthy controls. The decrease in skin blood flow following sympathetic provocation maneuvers, detected by laser Doppler flowmetry, was quantified as sympathetic reactivity. In the affected hands of CRPS I patients, as well as in the contralateral hands, the sympathetic reactivity was obliterated or diminished in contrast to the age-matched controls and normal fracture patients. A multivariate analysis did not reveal any correlation between sympathetic function and the severity of any clinical symptom. Sympathetic reactivity seems to be an independent variable in CRPS I and the test presented may facilitate the difficult clinical diagnosis of this disease.

The use of electrical stimulation and taping to address shoulder subluxation for a patient with central cord syndrome

BACKGROUND AND PURPOSE: This case report describes the examination, intervention, and outcome of a patient with central cord syndrome (CCS) who participated in acute rehabilitation that included the use of electrical stimulation (ES) and strapping to address shoulder subluxation. The only literature found describing these interventions for shoulder subluxation was for patients with stroke. CASE DESCRIPTION: The patient was a 29-year-old man with CCS and bilateral shoulder subluxation. He received ES over 8 weeks to the anterior and middle deltoid and supraspinatus muscles of the right shoulder. Taping was repeated every 3 to 4 days on both shoulders following over the anterior and middle deltoid muscles up to the acromion. OUTCOMES: The initial shoulder subluxation measurements were 1.5 cm on the right and 1.0 cm on the left. The final measurements were 0.3 cm on the right and 0.2 cm on the left. The patient's American Spinal Injury Association upper-extremity motor scores were 26/50 initially and 48/50 at discharge. CONCLUSION: The use of ES and shoulder taping in conjunction with other rehabilitation may have played a role in reducing the patient's shoulder subluxation.     

Shoulder pain in hemiplegia: results from a national rehabilitation hospital in Turkey

OBJECTIVE: Shoulder pain is a common complication after stroke that can limit the patients' ability to reach their maximum functional potential and impede rehabilitation. The aim of our study was to examine the occurrence of hemiplegic shoulder pain in a group of Turkish patients and clarify contributing factors such as glenohumeral subluxation, reflex sympathetic dystrophy, tonus changes, motor functional level, limitation in shoulder range of motion, thalamic pain, neglect, and time since onset of hemiplegia. The effect of shoulder pain on the duration of rehabilitation stay was also identified. DESIGN: A total of 85 consecutive patients with hemiplegia admitted to a national rehabilitation center were evaluated for the presence of shoulder pain. A brief history of pain was taken for each patient, and each patient was evaluated by radiographic and ultrasonographic examination. The subjects with shoulder pain were compared with those without pain in regard to certain of the above variables. RESULTS: Of the 85 patients with stroke, 54 patients (54/85, 63.5%) were found to have shoulder pain. Shoulder pain was significantly more frequent in subjects with reflex sympathetic dystrophy, lower motor functional level of shoulder and hand (P < 0001), subluxation, and limitation of external rotation and flexion of shoulder (P < 0,05). Age was also a significant factor in the development of shoulder pain. We were unable to demonstrate a significant relationship between shoulder pain and sex, time since onset of disease, hemiplegic side, pathogenesis, spasticity, neglect, and thalamic pain. There was no prolongation of rehabilitation stay in patients with shoulder pain. CONCLUSION: These results indicate that shoulder pain is a frequent complication after stroke and that it may develop from a variety of factors. To prevent and alleviate shoulder pain, efforts should be directed toward proper positioning of the shoulder, range of motion activities, and the avoidance of immobilization.     

The Outcome of Complex Regional Pain Syndrome Type 1: A Systematic Review

The purpose of this systematic review was to examine the outcome of complex regional pain syndrome (CRPS) type 1. We searched MEDLINE, Embase, and PsycINFO for relevant studies and included 18 studies, with 3,991 participants, in this review. The following data were extracted: study details, measurement tools used, and rates or severity scores for the symptoms/signs of CRPS at baseline and follow-up, or in groups of patients with different disease durations. A quality assessment revealed significant limitations in the literature, with many studies using different diagnostic criteria. The 3 prospective studies demonstrated that for many patients, symptoms improve markedly within 6 to 13 months of onset. The 12 retrospective studies had highly heterogeneous findings, documenting lasting impairments in many patients. The 3 cross-sectional studies showed that rates of pain and sensory symptoms were highest among those with the longest duration of CRPS. Additionally, most studies showed that motor symptoms (stiffness and weakness) were the most likely to persist whereas sudomotor and vasomotor symptoms were the most likely to improve. Overall, this suggests that some CRPS patients make a good early recovery whereas others develop lasting pain and disability. As yet little is known about the prognostic factors that might differentiate between these groups.PerspectiveWe found evidence that many CRPS patients recover within 6 to 13 months, but a significant number experience some lasting symptoms, and some experience chronic pain and disability. The quality of the evidence was poor. Future research should examine the factors associated with recovery and identify those at risk of poor outcomes.     

Shoulder-hand syndrome after stroke. A complex regional pain syndrome

Complex regional pain syndrome (CRPS) types I and II are neuropathic pain disorders that develop as an exaggerated response to a traumatic lesion or nerve damage, that generally affects the extremities, or as the consequence of a distant process such as a stroke, spinal lesion or myocardial infarction. It rarely appears without an apparent cause. CRPS of upper limbs after stroke is frequently today called shoulder-hand syndrome (SHS). The onset and severity of SHS appears to be related with the aetiology of the stroke, the severity and recovery of motor deficit, spasticity and sensory disturbances. Another important aetiological factor is glenohumeral subluxation. The physiopathology of the disease is still not known. In CRPS, there is an exaggerated inflammatory response and some chemical mediators have been identified and are present in the inflammatory soup around the primary afferent fibres that, through different processes, can induce hyper-excitability of the afferent fibres (peripheral sensitization). It is hypothesized that a localized neurogenic inflammation is at the basis of oedema, vasodilation and hyperhidrosis that are present in the initial phases of CRPS. The repeated discharge of the C fibres causes an increased medullary excitability (central sensitization). Another important factor is the reorganisation of the central nervous system, and in particular this appears to affect the primary somatosensory cortex. The central role of the sympathetic nerve is presently in doubt. However, it is thought that a sub-group of CRPS patients exists in whom a predominant factor is the hyper-activity of the sympathetic nervous system, and that it responds positively to sympathetic block. Diagnosis is clinical and there are no specific tests, nor pathognomic symptoms to identify this disease with certainty. Diagnosis of CRPS after stroke appears more complex than in other pathological situations: the paretic upper arm frequently appears painful, oedematose, with altered heat and tactile sensations and slightly dystrophic skin within a non-use syndrome. Some investigations can aid differential diagnosis with other diseases. Treatment may be non-pharmacological, pharmacological, with psychotherapy, regional anaesthesia, neuromodulation and sympathectomy. In any case there is little evidence that supports the efficacy of the interventions normally used to treat or prevent CRPS-SHS. The key to effective treatment undoubtedly lies in a an expert multidisciplinary team that is co-ordinated and motivated and that treats the disorder with individualised therapy.     

Absent median somatosensory evoked potential is a predictor of type I complex regional pain syndrome after stroke

Abstract

Purpose: The objective was to determine whether the abnormal finding of somatosensory evoked potentials (SEPs) associated with the development of type I complex regional pain syndrome (CRPS) after stroke. Methods: This was a retrospective study conducted from January, 2003, to December, 2007. Seventy patients were confirmed as CRPS type I, and one hundred and eighty-two patients were assigned to the control group. The initial clinical data were reviewed including age, gender, main type of stroke, lateralization and location of the lesion, presence of glenohumeral subluxation, and the development of CRPS. Somatosensory evoked potentials tests (SEP) in median nerve (N20) and posterior tibial nerve (P37) were performed. Results: CRPS groups revealed significantly higher incidence of the absent and abnormal hemiplegic median SEP, hemorrhagic stroke, and glenohumeral subluxation (GHS). Binary logistic regression analysis indicated that GHS (exp.(B)?=?4.083, p?<?0.01) with the absent median SEP (exp.(B)?=?3.246, p?<?0.01) were significant independent predictors of CRPS onset. Conclusions: In conclusion, GHS and the absent median SEP at sub-acute phase of stroke were primary predictors of the onset of post-stoke CRPS.

• Implications for Rehabilitation

• Recent investigations have suggested that autonomic, motor and somatosensory abnormalities of CRPS are impairments involving the central nervous system (CNS) as well as the peripheral neurogenic inflammatory process. However, the understanding of the pathophysiology of CRPS is still far from complete.

• The absence of SEP at the sub-acute stage of stroke correlated with the onset of post-stroke CRPS type I.

• The SEP evaluation at the sub-acute period after stroke might be generally used for predicting the concomitant development of post-stroke CRPS type I as well as functional recovery after stroke.

     

Percutaneous intramuscular neuromuscular electric stimulation for the treatment of shoulder subluxation and pain in patients with chronic hemiplegia: a pilot study

OBJECTIVE: To investigate the feasibility of percutaneous intramuscular neuromuscular electric stimulation (perc-NMES) for treating shoulder subluxation and pain in patients with chronic hemiplegia. DESIGN: Before-after trial. SETTING: University-affiliated tertiary care hospital. PARTICIPANTS: A convenience sample of 8 neurologically stable subjects with chronic hemiplegia and shoulder subluxation. INTERVENTION: Six weeks of perc-NMES to the subluxated shoulder. MAIN OUTCOME MEASURES: Shoulder subluxation (radiograph), shoulder pain (Brief Pain Inventory), motor impairment (Fugl-Meyer score), shoulder pain-free external rotation (handheld goniometer), and disability (FIM instrument) were assessed before treatment (T1), after 6 weeks of neuromuscular stimulation (T2), and at 3-month follow-up (T3). A 1-way, repeated-measures analysis of variance using the generalized estimating equation approach was used to evaluate differences from T1 to T2 and from T1 to T3 for all outcome measures. RESULTS: Subluxation (p =.0117), pain (p =.0115), shoulder pain-free external rotation (p <.0001), and disability (p =.0044) improved significantly from T1 to T2. Subluxation (p =.0066), pain (p =.0136), motor impairment (p <.0001), shoulder pain-free external rotation (p =.0234), and disability (p =.0152) improved significantly from T1 to T3. CONCLUSIONS: Perc-NMES is feasible for treating shoulder dysfunction in hemiplegia and may reduce shoulder subluxation, reduce pain, improve range of motion, enhance motor recovery, and reduce disability in patients with chronic hemiplegia and shoulder subluxation. Further investigation is warranted.     

Validation of the Bath CRPS Body Perception Disturbance Scale

The Bath Complex Regional Pain Syndrome Body Perception Disturbance Scale (“B-CRPS-BPDS”) measures alterations in body perception. We assessed its internal consistency, known group validity, construct validity, and associations with demographic and clinical characteristics. We also evaluated changes in, and baseline predictors of B-CRPS-BPDS scores at follow-up. We included people with CRPS (N = 114) and pain-free controls (N = 69). People with CRPS obtained higher scores than pain-free controls on all B-CRPS-BPDS items, except the item on attention. Because this item also had an insufficient corrected item-total correlation, we propose a revised B-CRPS-BPDS (r-B-CRPS-BPDS) excluding this item. The internal consistency of the r-B-CRPS-BPDS was good. The r-B-CRPS-BPDS showed a large positive relationship with “motor neglect-like symptoms”, indicating good construct validity. The r-B-CRPS-BPDS showed positive relationships with pain intensity, fear of movement, depression, and upper limb disability. There were no independent relationships with handedness, affected side, affected limb, disease duration, CRPS severity score, tension, anger, fatigue, confusion, and vigour. Finally, r-B-CRPS-BPDS scores did not consistently change over time. Our results demonstrate the utility of the r-B-CRPS-BPDS for measuring body perception disturbances in CRPS.PerspectiveThis article evaluates the validity of the Bath Complex Regional Pain Syndrome Body Perception Disturbance Scale (“B-CRPS-BPDS”) in CRPS, and assesses relationships with demographic and clinical variables. The proposed revised B-CRPS-BPDS appears to be a valid measure of body perception disturbances in CRPS.
