Urethro-vaginal reflux during micturition: An underestimated cause of urinary incontinence in adult women.

AIMS: To evaluate if urethrovaginal reflux (UVR) is an underestimated cause of insensible or postmicturition incontinence in adult women. METHODS: An observational and retrospective study was carried out on the computerized records of a neuro-urology department. Female patients who had insensible or postmicturition incontinence were investigated. Retrograde and voiding urethrocystography (UCG), urodynamic evaluation, urethral pressure profilometry, and anamnestic and clinical examination had to be available. RESULTS: Among the 79 adult female patients with insensible or postmicturition incontinence in whom the whole set of required evaluations was achieved, 16 had a UVR (mean age 47 ± 15 years). There were no urethral diverticula, urethrocele, vesicovaginal, or urethrovaginal fistula on their UCG. All of them also had a cystoscopy and a CT urography which did not establish any abnormality. CONCLUSIONS: UVR is not an exclusive pathology of children. This mechanism seems to be an underestimated cause of urinary incontinence in adult women. Retrograde and voiding UCG appears to be the gold standard to confirm the intravaginal reflux.

French clinical guidelines for peripheral motor nerve blocks in a PRM setting.

INTRODUCTION: Motor nerve blocks with anesthetic drug for local anesthesia are commonly used in physical and rehabilitation medicine (PRM), especially in the field of spasticity. Guidelines in this context are currently lacking. METHOD: Eighteen experts selected on the basis of their recognized experience by the scientific committees of the French PRM (SOFMER) and Anesthesia and Intensive care (SFAR) societies were invited to work and propose guidelines for the use of loco-regional anesthetic drug for motor nerve blocks in PRM setting. Eight issues were addressed: which neural blocks for which indications; drugs and contraindications; medical survey and attitude in case of adverse event; injection and guidance material; patient preparation and pain relief; efficacy assessment; patient information; education of PRM physiatrists. The Medline, Cochrane and Embase databases for the period 1999 to 2018 were consulted and 355 papers analyzed. The drafts were commented then approved by the whole group using electronic vote, before final approval by scientific committee of each society. RESULTS: No scientific evidence emerged from the literature. Thus, these guidelines are mainly based on the opinion of the expert panel. Guidelines for each issue are reported with the main points of arguments. The main question deals with the recommendation about doses for each drug: for lidocaine - up to 2mg/kg - "check contraindications, emergency truck available, no need of previous anesthetic consultation nor presence of anesthetic physician"; for ropivacaine - up to 1.5mg/kg, with a maximum of 100mg - the same but after intravenous line. Beyond these doses, SFAR guidelines have to be applied with the need of anesthetic physician. CONCLUSION: These are the first organizational guidelines devoted to increase the security of motor nerve block use in PRM settings.

Decrease in post-stroke spasticity and shoulder pain prevalence over the last 15 years.

OBJECTIVES: The usual complications after recent stroke such as disabling spasticity and shoulder pain seemed less frequent in recent years. This study examined the frequency of spasticity and shoulder pain in recent post-stroke patients over time in our physical and rehabilitation medicine department. METHODS: This was a retrospective study of post-stroke inpatients over the last 15 years. Spasticity and shoulder pain prevalence were analyzed, as were demographic, clinical and stroke characteristics. RESULTS: We reviewed medical records for 786 patients (506 men); mean age 58.1 years (SD 13.2); 530 (68%) with ischemic stroke and 256 (32.36%) hemorrhagic stroke. After a first increase from 2000 to 2006, the prevalence of disabling spasticity decreased from 2006 to 2015 (31%-10%; P<0.001). Shoulder pain at admission and during hospitalization also decreased (13% of patients in 2000 to 8% in 2015, P<0.001). Disabling spasticity was associated with shoulder pain (26% of patients with disabling spasticity presented shoulder pain at admission vs 7% with hyperreflexia of the deep tendon reflexes, P<0.05). Characteristics of stroke, time of admission after stroke and length of stay did not change over the years. We observed an increase in number of walking patients at admission and number with a functional paretic arm at admission and discharge (P<0.05), which may explain the increase in functional independence measure scores at admission and discharge (both P<0.05). Prevalence of cognitive disorders increased over the same period (24% in 2000 vs 63% in 2015, P<0.05). CONCLUSIONS: Disabling spasticity and shoulder pain frequency in recent post-stroke patients decreased over the last 15 years, and functional abilities both at admission and discharge improved. Confirmation of these results in a multicentric study may be important evidence of an improvement in stroke healthcare both in stroke and physical and rehabilitation medicine units in the last 10 years in France and could affect future estimations of the need for rehabilitation care after stroke.

Diffusion-Weighted Magnetic Resonance Imaging: A New Tool for the Diagnosis of Bladder Pain Syndrome/Interstitial Cystitis.

OBJECTIVES: To determine whether diffusion-weighted magnetic resonance imaging (DWMRI), a noninvasive procedure, can contribute to the diagnosis of bladder pain syndrome/interstitial cystitis (BPS/IC). METHODS: The pelvic DWMRI of patients with chronic pelvic pain syndrome was selected between January 2012 and June 2017. A radiologist analyzed the bladder wall signal; he was blinded to the patients' clinical data. According to the 2008 European Society for the Study of Bladder Pain Syndrome/Interstitial Cystitis criteria, 2 groups of patients were determined: BPS/IC and no BPS/IC. The association between BPS/IC and the wall signal intensity was compared. RESULTS: In the 106 patients included, 82 had criteria for BPS/IC and 24 did not. A significant difference in the distribution of the signal was found between the 2 groups (p = 0.01). High signal intensity of the bladder wall was related to the presence of a BPS/IC with a sensitivity of 28% and a specificity of 88%. No signal intensity of the bladder wall was related to the absence of a BPS/IC with a sensitivity of 96% and a specificity of 29%. CONCLUSIONS: In -DWMRI, high bladder wall signal intensity helps to affirm a BPS/IC, whereas the absence of signal helps to exclude the diagnosis. Further studies are needed to confirm these preliminary results.

Intervertebral disc and vertebral endplate subchondral changes associated with Modic 1 changes of the lumbar spine: a cross-sectional study.

BACKGROUND: Modic 1 changes are usually associated with degenerative disc disease (DDD). We aimed to compare Modic 1 changes with advanced degenerative disc disease (>50%-intervertebral space narrowing [IVSN]) to Modic 1 changes with less advanced lumbar degenerative disc disease (≤50%-IVSN). METHODS: We conducted a cross-sectional study. The computerized MRI database from a French tertiary care hospital was searched. Patients were included if they were ≥ 18 years old and had a lumbar MRI between January 1, 2006 and January 31, 2008, that showed a Modic 1 signal at a single level. The strength of the magnet was 1.5 T. MRI were reviewed by 2 assessors. Age and gender were recorded. MRI changes involving the intervertebral disc and the vertebral endplate subchondral bone were assessed for Modic 1 signal, intervertebral space narrowing, asymmetrical degenerative disc disease, spondylolisthesis, anterior and posterior intervertebral disc herniation, and anterior and lateral osteophytes. These outcomes were compared between >50%-IVSN Modic 1 and ≤50%-IVSN Modic 1 groups. For bivariate analysis, comparisons involved nonparametric Kruskal-Wallis test for quantitative variables and nonparametric Fisher's exact test for qualitative variables. Multivariate analysis was conducted to determine factors independently associated with <50%-IVSN Modic 1 changes by backward stepwise regression. Informed consent and formal approval from Institutional Review Board is not required for this type of study. This statement was confirmed by our Institutional Review Board. RESULTS: MRI for 101 individuals were eligible. Patients' mean (SD) age was 56.6(13.4) years, and 41/101(40.6%) were men. Modic 1 were most frequently observed at L4/L5 and L5/S1 (37[36.6%] cases each). As compared with >50%-IVSN Modic 1 patients, ≤50%-IVSN Modic 1 patients were younger (mean[SD] age 51.5[14.1] vs 58.8[12.6] years, p = 0.019), Modic 1 were more frequent at L5/S1 level (19[61.3%] vs 18[25.7%], p = 0.001), and anterior and lateral osteophytes were less frequent (13[41.9%] vs 55[78.6%], p < 0.001, and 11[35.5%] vs 48[68.6%], p = 0.002, respectively). CONCLUSIONS: ≤50%-IVSN Modic 1 are rather found in young men at L5/S1 level and are associated with less frequent osteophytes than >50%-IVSN Modic, while >50%-IVSN Modic 1 are rather found in older women at L4/L5 level.

Intermittent catheterization difficulty questionnaire (ICDQ): A new tool for the evaluation of patient difficulties with clean intermittent self-catheterization.

AIMS: Once a catheterization technique has been learned and acquired, psychological barriers have been overcome and a specific catheter has been selected, a patient will need to use clean intermittent self-catheterization (CISC) on a long-term basis. Over this long period of time, several technical or anatomical difficulties and local complications may be observed. The aim of this study was to construct and validate a specific test, referred to as the ICDQ (intermittent catheterization difficulty questionnaire), in order to evaluate and quantify patients' difficulties during CISC. METHODS: The questionnaire was validated in neurogenic patients. Thirteen items were chosen, concerning ease of catheter insertion and withdrawal, the presence of pain, limb spasticity, urethral sphincter spasms, and local urethral bleeding during catheterization. The frequency and intensity of these difficulties were scored. The comprehension, relevance, psychological and time consumption acceptance and face validity were evaluated. Reliability (internal consistency and test-retest reliability using the Intraclass Correlation Coefficient [ICC]) was carried out. RESULTS: The ICDQ was validated in 70 neurogenic patients (mean age 51.6 ± 13, 44 females, 26 males). Comprehension and acceptance of the questionnaire were good. Cronbach's alpha was α = 0.88. The ICC demonstrated good test-retest reliability. CONCLUSION: The ICDQ is a valid test for the evaluation of catheter use, and of patients' difficulties during CISC. However, in order to facilitate CISC, we propose the interpretation of ICDQ results, drug combinations such as the use of alpha-blockers or botulinum toxin injections in the external urethral sphincter, or a change of catheter.

Influence of a distraction task on pelvic floor muscle contraction.

AIMS: Attention may play a key role in the contraction of pelvic floor muscles in stressful situations, meaning that mental distraction may be involved in urinary incontinence. METHODS: Informed consent was obtained from 20 healthy volunteers. The electromyographic (EMG) activity of the external anal sphincter (EAS) was recorded during voluntary contraction elicited by local stimulation. The trials were carried out twice: combined (or not) with a mental distraction task (PASAT), Paced auditory serial additional test. Reaction time, latency between the stimulus and maximum EAS EMG activity, duration of the contraction, maximum EAS EMG activity, and the area under the EAS EMG activity curve were measured. RESULTS: The mental distraction task led to a 3.98 times greater reaction time (RT), (P = 0.00001 Wilcoxon's test). The RT increased from 217 (IQR: 170-270) to 779 msec (IQR: 550-1,025, P < 0.0001) when the EAS contraction was combined with PASAT. However, the maximum EAS EMG activity was weaker during PASAT than in the absence of a mental distraction task: 0.0850 mv versus 0.0701 mv, that is, 1.21 times weaker (P = 0.00077, Wilcoxon's test). Finally, when the two conditions (respectively with and without the mental distraction task) were compared, no significant difference was found in the area under the EAS EMG activity curve (0.0157 mv sec vs. 0.0162 mv sec, ratio 1.01, P = 0.52). CONCLUSIONS: The mental distraction task altered voluntary contraction of the pelvic floor muscles.

Need to void and attentional process interrelationships.

OBJECTIVES: To determine whether a strong urge to void could affect a person's attentional performance. To determine whether an attentional task could decrease a strong urge to void a prospective study was performed. SUBJECTS AND METHODS: Healthy adults were asked to perform two neuropsychological tests, the modified Paced Auditory Serial Addition Test (mPASAT) and the Psychology Experiment Building Language Continuous Performance Test (pCPT), under two different conditions: no need to void, and a strong urge to void defined by a score of >70/100 mm on a visual analogue scale. RESULTS: In all, 21 healthy volunteers were included. There was no statistical difference between the mPASAT scores from the two sessions (P = 0.57). The mean total error score of the pCPT increased with the individual's urge to void (P = 0.043). The mean omission score decreased, but was not statistically different (P = 0.129), the commission error score increased with the urge to void (P = 0.017), with a shorter reaction time for the inter-stimuli intervals of 1 (P<0.001) and 2 s (P = 0.036), suggesting a tendency to hurry. CONCLUSIONS: A strong urge to void can alter attentional performance, with a tendency to hurry, in healthy volunteers taking part in a sustained attention test pCPT involving the use of the anterior cingulate cortex.

Posterior vaginal wall pull down maneuver: a clinical test to diagnose intrinsic sphincter deficiency in women suffering from genuine urinary stress incontinence.

OBJECTIVES: To assess the predictive value of a simple clinical test (posterior vaginal wall pull down maneuver) in the diagnosis of intrinsic sphincter deficiency. METHODS: The present prospective study included 62 women suffering from stress urinary incontinence. Every patient underwent a urogynecological examination including multichannel urodynamic testing (cystometry, urethral pressure profile, Valsalva Leak Point Pressure measurement) and a clinical examination including posterior vaginal wall pull down maneuver. Posterior vaginal wall pull down maneuver was carried out with the bladder filled with 400 mL of saline in a supine position, and was obtained by means of a split speculum allowing gentle pull down traction of the posterior vaginal wall. Posterior vaginal wall pull down maneuver was considered as positive when a urine leak was observed during the manoeuvre. Intrinsic sphincter deficiency was urodynamically defined by maximum urethral closure pressure ≤20 cmH2 O. Correlations between positive/negative posterior vaginal wall pull down maneuver and urodynamic intrinsic sphincter deficiency were calculated. RESULTS: There was a statistical correlation between age and low maximum urethral closure pressure (P < 0.0001), and between low maximum urethral closure pressure and positive posterior vaginal wall pull down maneuver (P < 0.0001). Regarding the intrinsic sphincter deficiency diagnosis, the posterior vaginal wall pull down maneuver positive predictive value was 94.67% and the negative predictive value was 95.4%, with a specificity of 97.6% and sensitivity of 90%. CONCLUSION: Posterior vaginal wall pull down maneuver is a reliable clinical test, easy to carry out, inexpensive and without significant risk. This test allows the diagnosis of intrinsic sphincter deficiency in women suffering from stress urinary incontinence, thus avoiding further invasive urodynamic testing (urethral pressure profile, Valsalva Leak Point Pressure measurement) in women with genuine stress urinary incontinence. Furthermore, it is helpful when choosing the type of sling procedure (retropubic vs transobturator) when a surgery is planned.

Correlation between voiding dysfunction symptoms and uroflowmetry in women suffering from stress urinary incontinence.

OBJECTIVES: To determine whether the completion of a voiding dysfunction (VD) questionnaire could have a good predictive value for uroflowmetry findings, in a population of stress urinary incontinence (SUI) women. MATERIALS AND METHODS: From a urodynamic database of 415 SUI women, 93 with isolated SUI who underwent urodynamic investigations were eligible for this study. Patients with obvious etiologies of obstruction were excluded. VD symptoms were analyzed using the Bristol Female Lower Urinary Tract Symptoms Questionnaire. Bladder outlet obstruction (BOO) was defined as a maximal flow rate under 15 ml/s for a urine volume > 200 ml, or a post-void residual volume greater than 50 ml, or an abnormal pattern of the flow curve. The sensitivity, specificity, positive and negative predictive value of questioning VD were calculated. Statistical analysis was done using a Wilcoxon test for continuous data and Fisher exact test for categorical data, and multivariate analysis. RESULTS: Reported VD had a poor specificity (41%) and positive predictive value (32%) of BOO on uroflowmetry. No statistical correlation was found between VD symptoms and BOO defined on uroflowmetry (P=0.64) in this specific SUI population showing no obvious etiologies of obstruction. CONCLUSIONS: No correlation was found between obstructive symptoms and BOO as defined on uroflowmetry, in a specific population of SUI women. Our results suggest that uroflowmetry may be necessary rather than multichannel urodynamics.

[Approach to urinary incontinence in women]. / Démarche devant une incontinence urinaire chez la femme.

Urinary incontinence is a very common problem in women; it can lead to a specific alteration of quality of life which is necessary to evaluate before any treatment. Various types of incontinence can be described: stress incontinence, urge incontinence, mixed incontinence. Clinical examination is always necessary to exclude a specific cause of incontinence particularly neurogenic dysfunction in which incontinence may be the first symptom before motor or sensitive alterations appearance. Urodynamic investigations can easily determine pathophysiologic factors and allow a best choice of therapeutic strategies. Concerning stress urinary incontinence, first line treatment consists of pelvic floor exercices before surgical therapy, and anticholinergic drugs are always tried in urge incontinence before sacral neuromodulation.

Evidence for autonomic nervous system dysfunction in females with idiopathic overactive bladder syndrome.

AIMS: Micturition and continence are largely under the control of the autonomic nervous system (ANS). In this study, we analyzed ANS function using autonomic cardiovascular (CV) testing in females with idiopathic overactive bladder syndrome (iOAB) versus control females. Our hypothesis was that ANS dysfunction could comprise part of the pathophysiology of iOAB. METHODS: Twenty-three females with iOAB and 29 controls were enrolled into this prospective study. Patients performed CV autonomic testing, including two sympathetic tests (hand grip exercise and cold pressor test), two parasympathetic tests (deep breathing and 30:15 ratio), and two mixed tests (Valsalva manoeuvre and blood pressure [BP] response to standing). Patients with iOAB also underwent conventional urodynamic studies in order to define iOAB as either with or without demonstrable detrusor overactivity (DO). RESULTS: Both groups were similar with respect to age and menopausal status. Females with iOAB had significantly more positive tests than controls (P < 0.0001), particularly for sympathetic tests (P < 0.0001). Among the iOAB group, the sympathetic tests (P = 0.03) were significantly more often positive in patients without DO (based on cystometry) compared to patients with DO, with the results being particularly significant for the cold pressor test (P = 0.02). No differences were found among iOAB sufferers with respect to a past history of enuresis. CONCLUSIONS: These results suggest ANS dysfunction, predominantly a sympathetic ANS dysfunction, is associated with iOAB, specifically in patients with iOAB without DO.

McMaster-Toronto Arthritis Patient Preference Disability Questionnaire sensitivity to change in low back pain: influence of shifts in priorities.

OBJECTIVE: To assess the sensitivity to change of the McMaster Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR) in chronic low back pain (CLBP) and shifts in patients' priorities of disabling activities over time. METHODS: A prospective longitudinal survey of 100 patients (38 males) with CLBP in a tertiary care teaching hospital. Evaluation at baseline and 6 months by the MACTAR, Quebec Back Pain Disability Questionnaire (QUEBEC), Hospital Anxiety and Depression scale (HAD), Fear-Avoidance Beliefs Questionnaire (FABQ), Coping Strategies Questionnaire (CSQ), and pain and handicap visual analogue scales (VASs). Patients' perceived improvement or worsening of condition was assessed at 6 months. Effect size (ES) and Standardized response mean (SRM) and effect size (ES) were used to evaluate sensitivity to change of the MACTAR. RESULTS: The MACTAR SRM and ES values (SRM = 0.25; ES = 0.37) were among the highest for the instruments evaluated. For patients considering their condition as improved, the SRM was 0.66 and the ES 1. The 3 disability domains, classified by the International Classification of Functioning, Disability and Health (ICF), most often cited as priorities at baseline remained the most cited at follow-up: mobility (40.9% of patients); community, social and civic life (22.7%); and domestic life (22.4%). At 6 months, 48 patients shifted their priorities, for a decrease in MACTAR SRM and ES values for patients considering their condition improved and an increase in these values for those considering their condition deteriorated. CONCLUSIONS: Although the MACTAR has similar sensitivity to change as other outcome measures widely used in CLBP, shifts in patient priorities over time are common and influence scores and sensitivity to change.

Modulation of the rectoanal inhibitory reflex (RAIR): qualitative and quantitative evaluation in multiple sclerosis.

BACKGROUND: Rectoanal inhibitory reflex (RAIR) is a physiological modulated reflex involved in anorectal continence and defined by a relaxation of internal anal sphincter following rectal distension. Its existence depends on intramural autonomic ganglions and its modulation on the integrity of the autonomic nervous system (ANS). AIMS: The aim of this study was to analyse RAIR modulation in terms of amplitude and duration in multiple sclerosis (MS) patients. METHODS: Twenty-one patients with MS and 40 control patients had anorectal manometry. Qualitative assessment (presence or absence) of RAIR was evaluated together with its modulation in amplitude and in duration. RESULTS: All patients had present RAIR for each volume of rectal distension (10-50 ml). Seven patients (33.3%) in the MS group had abnormal RAIR modulation in amplitude (odds ratio (OR) = 2.78, compared to control group, p = 0.11). Nine patients (42.9%) in the MS group had abnormal RAIR modulation in duration (p = 0.14, OR = 2.54, compared to control group). Alteration of RAIR modulation was not correlated with Expanded Disability Status Scale, faecal incontinence and constipation (p > 0.05). Course of MS (relapsing-remitting MS or secondary progressive form) seems to be correlated to alteration of modulation in amplitude and in duration (OR = 1.31 and 1.07). CONCLUSION: Even if our results do not have the required statistical significance (p > 0.05), they are interesting. If RAIR is always present in MS, its modulation seems to be altered. A hypothesis for this lack of RAIR modulation could be the alteration of ANS, often involved in MS besides somatic nervous system lesions.

Pencil and paper test: a new tool to predict the ability of neurological patients to practice clean intermittent self-catheterization.

PURPOSE: We created and validated the new pencil and paper test, which allows assessment of the ability of patients with a neurological disorder to practice clean intermittent self-catheterization. MATERIALS AND METHODS: We developed a simple test including common gestures mimicking the usual maneuvers needed during clean intermittent self-catheterization, and involving the same cognitive and physical resources needed for this technique. We evaluated the test in 118 patients with a neurological condition. Instruments needed to perform the pencil and paper test are limited to a sheet of paper and a pencil. Each test item was quantified and graded with a total score of 15. A specific clean intermittent catheterization learning scale was used to classify the outcome of the ability to perform clean intermittent self-catheterization with a score range of 5--learning easy and self-catheterization complete to 0--learning impossible. RESULTS: Enrolled in the study were 118 patients with a neurological condition. There was strong correlation between the global pencil and paper test score, and the ability to perform clean intermittent self-catheterization, as evaluated by the learning scale (r = 0.82, p = 0.000091). At a test cutoff of 10 and a clean intermittent self-catheterization cutoff of 3, which was the limit needed to practice self-catheterization alone, the positive predictive value of the pencil and paper test was 85% and its negative predictive value was 94% (Cronbach's α = 0.88). CONCLUSIONS: The pencil and paper test is a valid way to predict the ability to practice clean intermittent self-catheterization in patients with a neurological disorder.

Assessment of ankylosing spondylitis criteria in patients with chronic low back pain and vertebral endplate Modic I signal changes.

OBJECTIVE: Patients with chronic low back pain (cLBP) and vertebral endplate Modic I signal changes on lumbar magnetic resonance imaging (MRI) have clinical features that could mimic inflammatory back pain related to spondyloarthritis (SpA) and/or ankylosing spondylitis (AS). We aimed to assess whether such patients fulfilled criteria for SpA and/or AS. METHODS: For 5 months in 2008, all patients (n = 314) referred to a tertiary care physical medicine and rehabilitation facility in France were consecutively screened. A total of 185 hospitalized for non-specific cLBP were prospectively assessed. Forty patients fulfilling inclusion criteria were consecutively enrolled and included in 2 groups according to MRI findings: Modic I (n = 15) and non-Modic I (n = 25). MRI findings were assessed independently by 2 spine specialists and a radiologist. HLA-B27 status was determined. Data were collected on clinical measurements and fulfillment of Amor criteria (AC) and modified New York criteria (mNYC). All assessors were blinded to HLA-B27 status. RESULTS: Whatever the Modic group, no patient fulfilled AC or mNYC, and mean total scores were comparable [3 ± 2 (range 0-22; p = 0.977), 1 ± 1 (range 0-3; p = 1.000), and 0 ± 0 (range 0-1; p = 1.000) for AC and clinical and radiological mNYC, respectively]. HLA-B27 status was similar in both groups [n = 2 (13%) vs n = 0 (0%); p = 0.135]. CONCLUSION: Patients with cLBP and Modic I vertebral endplate signal changes on lumbar MRI do not fulfill widely used and validated criteria for SpA and/or AS. Such cases are clinically distinct from SpA and AS.

Patient-preference disability assessment for disabling chronic low back pain: a cross-sectional survey.

STUDY DESIGN: A cross sectional survey. OBJECTIVE.: To assess patient priorities in disability and restriction in participation with disabling chronic low back pain (CLBP) by use of the McMaster-Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR) and to compare this questionnaire with other outcome measures widely used in this situation. SUMMARY OF BACKGROUND DATA: Disability and participation restriction are widely assessed in CLBP but do not account for patient priorities. Knowing what is important to patients could be useful to help form treatment goals and plans. METHODS: A total of 150 patients hospitalized in a tertiary care teaching hospital for the management of CLBP were enrolled in the study. Evaluation was by the MACTAR, the Quebec Back Pain Disability Questionnaire (QUEBEC), the Hospital Anxiety and Depression scale, the Fear-Avoidance Beliefs Questionnaire, the Coping Strategies Questionnaire, and pain and handicap visual analog scales. Correlations between the MACTAR score and scores for other scales were analyzed by the Spearman coefficient. RESULTS: On the MACTAR, patients with CLBP cited as most important 3 disability domains classified by the International Classification of Functioning, Disability, and Health: mobility (n = 23 activities, 165 times, 33% of the patients); community, social, and civic life (n = 7 activities, 138 times, 27.6% of the patients); and domestic life (n = 10 activities, 123 times, 24.6% of the patients). Patients ranked first in importance 37 different activities, especially sport (n = 29 times; 19.3% of the patients), shopping (n = 14; 9.3% of the patients), and walking (n = 13; 8.7% of the patients). The MACTAR score was correlated moderately with visual analog scale handicap (r = 0.51), weakly with the QUEBEC score (r = 0.40), and not at all with Hospital Anxiety and Depression scale, Fear-Avoidance Beliefs Questionnaire, and Coping Strategies Questionnaire scores. CONCLUSION: For assessing priorities in disability and participation restriction among patients with CLBP, the MACTAR has acceptable construct validity. The weak correlation between QUEBEC and MACTAR scores suggests that the latter scale adds useful information for assessing the health priorities of disabled CLBP patients.
