Characterizing the Experience of Spasticity after Spinal Cord Injury: A National Survey Project of the Spinal Cord Injury Model Systems Centers.

OBJECTIVE: To characterize the qualities that individuals with spinal cord injury (SCI) associate with their experience of spasticity and to describe the relationship between spasticity and perceived quality of life and the perceived value of spasticity management approaches. DESIGN: Online cross-sectional survey. SETTING: Multicenter collaboration among 6 Spinal Cord Injury Model Systems hospitals in the United States. PARTICIPANTS: Individuals with SCI (N=1076). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Qualities of Spasticity Questionnaire, modified Spinal Cord Injury-Spasticity Evaluation Tool (mSCI-SET), and the modified Patient-Reported Impact of Spasticity Measure (mPRISM). RESULTS: Respondents indicated that spasms most often occurred in response to movement-related triggering events. However, spontaneous spasms (ie, no triggering event) were also reported to be among the most common types. Frequency of spasms appears to decline with age. The highest frequency of spasms was reported by 56% of respondents aged <25 years and by only 28% of those >55 years. Stiffness associated with spasticity was reported to be more common than spasms (legs, 65% vs 54%; trunk, 33% vs 18%; arms, 26% vs 15%). Respondents reported negative effects of spasticity more commonly than positive effects. Based on their association with negative scores on the mSCI-SET and the mPRISM, the 5 most problematic experiences reported were stiffness all day, interference with sleep, painful spasms, perceived link between spasticity and pain, and intensification of pain before a spasm. Respondents indicated spasticity was improved more by stretching (48%) and exercise (45%) than by antispasmodics (38%). CONCLUSIONS: The experience of spasticity after SCI is complex and multidimensional, with consequences that affect mobility, sleep, comfort, and quality of life. Stiffness, rather than spasms, appears to be the most problematic characteristic of spasticity. Physical therapeutic interventions to treat spasticity warrant in-depth investigation.

Injury rate and pattern among Brazilian jiu-jitsu practitioners: A survey study.

OBJECTIVE: To determine the 6-month incidence rate and pattern of Brazilian jiu-jitsu (BJJ)-related injuries and characterize associations between injuries and experience level, demographic factors, and training variables. DESIGN: Descriptive epidemiology study. SETTING: Online survey. PARTICIPANTS: 1287 adult BJJ practitioners. OUTCOME MEASURES: 6-month BJJ-related injury incidence, anatomical pattern of injuries, and injury-associated demographic and training variable identification. RESULTS: 59.2% of practitioners reported at least one injury over 6 months. The knee was the most common site. Logistic regression analysis demonstrated 6-month injury incidence was negatively associated with years of training and body weight, and positively associated with training days per week and instructor status. More experienced athletes were more likely to report low back injury, while less experienced athletes more frequently reported head, upper extremity, and elbow injuries. None of the following variables were predictive of injury risk: gi preference, instruction on break-falling, and participation in a structured beginner's program. CONCLUSIONS: The risk factor analysis is applicable to BJJ instructors interested in reducing student injury risk. The widespread pattern of injuries and the distinction between types of injuries sustained at different levels of experience are notable findings that sports medicine practitioners should keep in mind when working with BJJ athletes.

Chronic neuropathic pain in SCI: evaluation and treatment.

Chronic neuropathic pain develops in approximately 40% of people after a spinal cord injury (SCI) and is notoriously difficult to treat. Because of the frequent presence of more than one pain type and the complex mechanisms and symptoms associated with pain in individuals with SCI, a thorough evaluation is important. This review includes an overview of the most recent guidelines for evaluating and classifying pain, suggestions for standardizing outcome measures for clinical use, and a review of the positive and negative evidence for pharmacologic and nonpharmacologic interventions to consider when treating individuals with SCI and chronic neuropathic pain.

Utility of quantitative computerized pain drawings in a sample of spinal stenosis patients.

OBJECTIVE: To evaluate the utility of quantitative computerized pain drawings (CPDs) in a sample of spine patients before and after surgery. DESIGN: Analysis of changes in quantified CPDs, the Oswestry Disability Index (ODI), the Short Form-36 Health Survey Questionnaire (SF-36), and numerical ratings of pain intensity before and after surgery. SETTING: Private clinic in large metropolitan area. Patients. Forty-six patients with spinal stenosis. Interventions. Surgery for the relief of pain due to spinal stenosis. OUTCOME MEASURES: A total points (TP) score was calculated from the CPD that reflected the total number of pixels filled by the patient, and the percentage of total pain area indicated as aching, stabbing, numbness, pins and needles, burning, and other, were each calculated separately. CPD scores, ODI score, Physical Components Summary (PCS) and Mental Components Summary scores of the SF-36, and pain intensity ratings (0-10 scale) were all recorded before and after surgical intervention. Results. After surgery, patients showed significant improvements in the extent of shaded pain area of the CPD, pain intensity ratings, ODI, and SF-36 PCS scores (paired t-test, P < or = 0.01). Changes in TP scores calculated from the CPDs were significantly correlated (P < or = 0.05) with changes in ODI scores (r = 0.34) and pain intensity ratings (r = 0.37). Changes in the percentage of total pain area covered by specific qualities of pain were not significant. CONCLUSIONS: Results from the present study provide initial support for the use of automated quantified data collected from CPDs to evaluate treatment interventions and to serve the clinician as a record of changes in spatial location, radiation or extent of pain, and the sensory quality of pain when evaluating individual patient needs.

Psychosocial subgroups in persons with spinal cord injuries and chronic pain.

OBJECTIVES: To define adaptational subgroups in people with chronic pain and spinal cord injury (SCI), and to compare these subgroups with respect to demographic factors, level of injury, functional independence, pain disability, depressed mood, social support, and life satisfaction. DESIGN: Interviews. SETTING: Veterans Affairs medical center and The Miami Project to Cure Paralysis. PARTICIPANTS: Persons with SCI and chronic pain (N=190). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The Multidimensional Pain Inventory, SCI version. RESULTS: Cluster analysis revealed 3 subgroups: (1) dysfunctional (34.6% of all participants), characterized by higher pain severity, life interference, and affective distress scores, and lower levels of life control and activities scores; (2) interpersonally supported (33.0% of participants), characterized by moderately high pain severity, and higher life control, support from significant others, distracting responses, solicitous responses, and activities scores; and (3) adaptive copers (32.4% of participants), characterized by lower pain severity, life interference, affective distress, support from significant others, distracting responses, solicitous responses, activities and higher life control scores. Compared with the dysfunctional subgroup, the interpersonally supported subgroup reported significantly greater social support and life satisfaction and less pain disability and emotional distress, despite moderately high pain severity. CONCLUSION: Three subgroups, independent of sex, pain duration, and functional status, were identified. Although severe pain significantly decreases life satisfaction after SCI, its impact is moderated by perceived social support.

Chronic pain after spinal cord injury: what characteristics make some pains more disturbing than others?

Different types of pain are often present in the same individual with spinal cord injury (SCI). Relieving the most disturbing of these pains may substantially affect quality of life. Persons with SCI and chronic pain (n = 194) completed a structured interview that detailed the characteristics of each pain they experienced. Pairwise analyses revealed that the following characteristics were more common among the most disturbing pains: "sharp"; "stabbing"; located at the level of injury; frequently aggravated; and having high intensity, unpleasantness, constancy, interference, and neuropathic pain-like features. A conditional logistic regression analysis showed that the combination of "sharp" and high pain intensity, interference, aggravation, and constancy significantly predicted the most disturbing pain (p < 0.001). This study suggests that, in addition to pain intensity, factors such as interference, quality, aggravation, and constancy of pain are important to consider when one evaluates SCI-related pain, since these symptoms may indicate pains that are particularly disturbing to an individual with SCI.
