Laryngeal and Global Somatosensation in Primary Muscle Tension Dysphonia.

INTRODUCTION: Primary muscle tension dysphonia (pMTD) is a functional voice disorder that reduces communicative abilities and adversely impacts occupational productivity and quality of life. Patients with pMTD report increased vocal effort, fatigue, discomfort, and odynophonia. Although laryngeal and paralaryngeal muscle tension and hyperfunction are the most commonly proposed mechanisms underlying these symptoms, recent studies suggest pMTD may have more to do with the somatosensory system. However, relationships between voice symptoms and somatosensory mechanisms are poorly understood, creating challenges for mechanistic-based pMTD management. The first objective was to compare laryngeal, paralaryngeal, and global somatosensation between subjects with and without pMTD. The second was to determine relationships between pMTD symptoms and somatosensation. METHODS: Fifty-two (20 pMTD and 32 control) subjects underwent laryngeal sensory testing with aesthesiometers, as well as peripheral mechanosensory and dynamic temporal summation testing to paralaryngeal and limb regions. Voice symptom severities (vocal effort, fatigue, discomfort, and odynophonia) were collected on 100-mm visual analog scales before and after laryngeal sensory testing. Participants also completed the Central Sensitization Inventory. RESULTS: Patients with pMTD reported significantly higher laryngeal sensations (P = 0.0072) and voice symptom severities (P < 0.001) compared with the control group, and had significantly more vocal tract discomfort postlaryngeal sensory testing compared with the prelaryngeal sensory testing timepoint (P = 0.0023). However, there were no significant group differences in laryngeal airway protection responses suggestive of peripheral laryngeal hypersensitivities (P = 0.444). There were also no significant group differences on paralaryngeal or global sensitivities (P > 0.05), and no correlations between severity of voice symptoms and perceptual laryngeal sensations or hypersensitivities (P > 0.05). CONCLUSION: Patients with pMTD perceive more sensitivities in the larynx and feel more sensations related to the voice (vocal effort, fatigue, discomfort, and pain). However, in general, patients with pMTD do not have abnormal peripheral laryngeal hypersensitivities, increased global somatosensation, or heightened central sensitivity. The lack of significant correlations between peripheral laryngeal hypersensitivities and voice symptom severity ratings suggests these outcome variables target distinct mechanistic constructs.

Predictors of attrition in an interdisciplinary pain management program.

PURPOSE/OBJECTIVE: This study sought to investigate the extent to which demographic and clinical characteristics predict which patients drop out of an interdisciplinary pain management program (IPP). RESEARCH METHOD/DESIGN: Participants (N = 178 outpatients, 18-75 years of age) received treatment for various chronic pain conditions in an IPP (including biopsychosocial assessment, cognitive-behavioral, and physical therapies). Separate logistic regression analyses identified the demographic and clinical variables most predictive of attrition across five domains: (a) demographics, (b) number of medical and non/psychiatric diagnoses, (c) opioid use (yes versus no)/risk of misuse, (d) pain-related cognition and behavior, and (e) physical, social, and mental well-being. Significant predictors from the five domains were integrated in a final multivariable logistic regression model. RESULTS: Among patients exposed to a 4-week IPP, 34% dropped out. In the final model, significant predictors of higher odds of attrition included younger age or being unemployed. Also, patients on opioids at preintervention had higher odds of completing the IPP than patients not on opioids at preintervention. Follow-up analyses revealed 24 of 37 completers (65%) on opioids at preintervention reduced or eliminated use over the course of the IPP. CONCLUSIONS/IMPLICATIONS: Because findings are limited by sample and design characteristics, they require replication yet offer novel hypotheses for identifying patients at risk of attrition. Specifically, patients with preintervention opioid use (contrasted with opioid dependence) may particularly benefit from an IPP. Patients at highest risk for early dropout can be targeted for specific engagement interventions to promote completion and effectiveness of IPP.

Validity and reliability of dry needle placement in the deep lumbar multifidus muscle using ultrasound imaging: an in-vivo study.

OBJECTIVES: To use ultrasound (US) imaging to determine the validity and reliability of needle placement of two dry needling (DN) protocols for the lumbar multifidus (LM) in individuals with a high body mass index (BMI). METHODS: Twenty-one participants with a BMI higher than 25 kg/m2 completed the study. A US scanner was used to determine the location of needle placement after a 100 mm long needle was inserted in the LM at L4 and L5 following two DN protocols for the deep LM muscle. US images were saved and viewed 6 months later to determine the intra-tester reliability. RESULTS: The probability of reaching the deep LM muscle was high (85-95%) at L4 and L5. Although the needle reached a bony landmark 85-100% of the time, it only reached the vertebra lamina as intended 70-75% of the time. The intra-tester reliability of needle placements based on analysis of real-time and recorded US images was poor-to-moderate. CONCLUSIONS: Although the bony drop may not indicate that the needle has reached the vertebra lamina as the protocol intended, reaching a bony drop is still meaningful as it coincided with reaching the LM in the majority of participants.

Using quantitative sensory testing to predict attrition in an interdisciplinary pain management program: a pilot study.

Aim: To determine the extent to which quantitative sensory testing (QST) predicted attrition in an interdisciplinary pain program (IPP). Patients & methods: Participants (n = 53) enrolled in an IPP completed pretreatment assessments of QST and the PROMIS-29 quality of life survey. Results & conclusion: Compared with completers, non-completers (24.5%) reported significantly higher pain intensity (7.1, 95% CI [5.8, 8.4] versus 5.4, 95% CI [4.8, 6.1]) and cold hyperalgesia (14.6°C, 95% CI [8.8, 20.4] versus 7.5°C, 95% CI [4.8, 6.1]), with both variables also predicting attrition. This finding highlights a potentially novel and clinically significant use of QST. Higher overall pain intensity and the presence of remote cold hyperalgesia may identify patients at risk for dropping out of an IPP.

The purpose of this research study was to determine the extent to which quantitative sensory testing (QST) predicted which patients enrolled in an interdisciplinary pain program (IPP) would drop out. Fifty-three patients with chronic pain enrolled in an IPP were assessed before treatment with mechanical and thermal QST at a painful and a non-painful site, as well as with the PROMIS-29 quality of life survey. Pretreatment findings were compared between non-completers (i.e., attended five or fewer sessions for any component of the IPP) and completers. Resulting significant predictors were included in a logistic regression to predict attrition. Compared with those who completed the program, non-completers (24.5%) reported significantly higher pain intensity and oversensitivity to cold at a non-painful site pretreatment, with both variables also predicting completion of the IPP. In summary, these preliminary findings suggest that higher overall pain intensity and the presence of cold oversensitivity (at baseline) may identify patients at risk for dropping out of an IPP.

Androgen Deprivation Therapy Differentially Impacts Bone and Muscle in the Short Term in Physically Active Men With Prostate Cancer.

Androgen deprivation therapy (ADT) is a cornerstone of advanced prostate cancer (PCa) therapy. Its use is associated with a loss of bone mineral density (BMD) and a greater risk of falls and osteoporotic fractures. In this prospective cohort study, we examined the impact of ADT on muscle and bone strength in men initiating ADT for PCa. Participants were evaluated at three time points: immediately before (week 0), and 6 and 24 weeks after ADT initiation. Study measures included fasting blood levels (for markers of muscle and bone metabolic activity), MRI and QCT imaging (for muscle fat content, and bone density and architecture), and validated clinical tests of muscle strength and gait. Sixteen men completed all study visits. At baseline and throughout the study, participants exercised a median of four times/week, but still experienced weight gain (+2.0 kg at week 24 versus week 0, p = 0.004). Biochemically, all men sustained dramatic early and persistent reductions in sex hormones post-ADT, along with a progressive and significant increase in serum C-telopeptide of type I collagen (CTX, +84% at week 24 versus week 0). There was a trend for rise in serum sclerostin (p = 0.09) and interleukin 6 (IL-6) (p = 0.08), but no significant change in serum myostatin (p = 0.99). Volumetric BMD by QCT declined significantly at the femoral neck (-3.7% at week 24 versus week 0), particularly at the trabecular compartment. On MRI, there were no significant changes in thigh muscle fat fraction. On physical testing, men developed weaker grip strength, but experienced no worsening in lower extremity and lumbar spine muscle strength, or on functional tests of gait. In conclusion, in physically active men, ADT for 24 weeks results in a significant increase in bone resorption and reduction in BMD, but nonsignificant changes in thigh muscle quality (on imaging) or strength and gait (on functional testing). © 2021 The Authors.

Improved symptoms of complex regional pain syndrome after novel lymphatic treatment and interdisciplinary pain management.

INTRODUCTION: Complex regional pain syndrome (CRPS) is a pain syndrome with no singular mechanism and no specific cure. The aim of this case report is to study the impact of Lymphatic Enhancement Technology (LET) treatment on CRPS-related symptoms. METHODS: A 51 year-old female presented with a chief complaint of severe, refractory ankle pain and CRPS related to a tibial and fibular fracture sustained three years earlier. The patient completed twelve cognitive behavioral therapy sessions over a 4-week period, and eleven physical therapy sessions over a four-month period, six of which utilized LET. RESULTS: Pain and swelling were largely unchanged with interdisciplinary treatment before the introduction of LET. A within-session change of 37.5% in pain intensity and 87.5% in ankle girth was observed immediately after the first application of LET. Three months after beginning LET treatment, the patient maintained a 43.8% improvement in pain intensity and 100% improvement in measurements of lower extremity girth and ankle range of motion. No side effects or adverse events were associated with the LET treatment. CONCLUSION: Swelling, pain, and mobility loss are common symptoms and features of CRPS. LET is a novel, non-invasive treatment that appears to be quite safe and effective for improving pain, swelling, and mobility loss related to CRPS.

Segmental spine mobility differences between lumbar flexion- and extension-based movement syndromes in patients with low back pain.

BACKGROUND: The Movement System Impairment (MSI) model is useful for identifying spine-hip mobility and motor control deficits that may contribute to low back pain (LBP). While previous studies have found differences in global spine-hip movement impairments between lumbar MSI subgroups, no studies have compared segmental spine movement impairments between these subgroups. Therefore, the purpose of this study is to analyze segmental lumbar mobility in participants with LBP and a lumbar flexion- or extension-based MSI. METHODS: Forty participants with subacute-chronic LBP were placed into one of three age groups (< 35, 35-54, or > 54 years-old) and then classified into a flexion- or extension-based MSI sub-group. Segmental lumbar range of motion (ROM) was measured in degrees using a skin-surface device. Total lumbar and segmental flexion and extension ROM of L1-L2 to L5-S1 was compared between MSI sub-groups for each age group using separate two-way ANOVAs. RESULTS: Significant main effects were found for the independent variables of MSI subgroup and age. Participants in all three age groups with a flexion-based MSI displayed significantly less lumbar extension (-0.6∘) at L4-5 as compared to participants with an extension-based MSI (-2.1∘), p= 0.03. In addition, lumbar total and segmental ROM was significantly less for older individuals in both subgroups. CONCLUSIONS: Individuals with LBP may demonstrate a pattern of lumbar segmental hypomobility in the opposite direction of their MSI. Future studies may investigate the added value of direction-specific spinal mobilization to a program of MSI-based exercise.

Impact of Faculty and Programmatic Resources on the Proportion of Academic Doctoral Degrees in Professional Physical Therapist Education Programs.

OBJECTIVE: The Commission on Accreditation in Physical Therapy Education has introduced a requirement that 50% of core faculty members in a physical therapist education program should have an academic doctoral degree, which many programs are not currently meeting. Competition between programs for prestige and resources may explain the discrepancy of academic achievement among faculty despite accreditation standards. The purpose of this study was to identify faculty and program characteristics that are predictive of programs having a higher percentage of faculty with academic doctoral degrees. METHODS: Yearly accreditation data from 231 programs for a 10-year period were used in a fixed-effects panel analysis. RESULTS: For a 1 percentage point increase in the number of core faculty members, a program could expect a decline in academic doctoral degrees by 14% with all other variables held constant. For a 1% increase in either reported total cost or expenses per student, a program could expect a 7% decline in academic doctoral degrees with all other variables held constant. Programs that have been accredited for a longer period of time could expect to have proportionately more faculty members with academic doctoral degrees. CONCLUSIONS: Programs may be increasing their core faculty size to allow faculty with academic doctoral degrees to focus on scholarly productivity. The percentage of faculty with academic doctoral degrees declines as programs increase tuition and expenditures, but this may be due to programs' tendency to stratify individuals (including part-time core faculty) into teaching- and research-focused efforts to maximize their research prowess and status. IMPACT: This study illuminates existing relationships between physical therapist faculty staffing, time spent in research versus teaching, and program finances. The results of this study should be used to inform higher education policy initiatives aimed to lower competitive pressures and the costs of professional education.

Faculty and programmatic influences on the percentage of graduates of color from professional physical therapy programs in the United States.

The physical therapy profession in the United States suffers from a shortage of providers of color. This is unlikely to change with newly graduating students, as 2.6% of 2017 graduates were African American and 5.7% were Hispanic or Latino. Faculty mentorship has a more profound influence on the retention of underrepresented minority students as compared with students from privileged backgrounds, according to undergraduate literature. The influences of faculty characteristics on physical therapy graduates of color are unknown. The purpose of this study was to determine faculty and programmatic characteristics that could influence the percentage of physical therapy graduates of color. This study implemented the theory of academic capitalism to inform the results of a retrospective panel analysis, which used accreditation data from 2008 to 2017. Data from 231 programs was used to create fixed effects and random effects models to estimate the effects that faculty and program characteristics had on the percentage of graduates of color that a program produced. There was a statistically significant positive relationship between faculty of color and graduates of color (p < 0.001), but faculty must be sufficiently diverse before a program can expect a meaningful change in their percentage of graduates of color. Academic capitalist principles suggest that competition between programs for resources could negatively influence the proportion of graduates of color. Cause and effect associations between variables cannot be established. The authors concluded that professional physical therapy programs appeared to have increases in the percentages of graduates of color when they had more core faculty members of color.

Quantitative Sensory Testing Discriminates Central Sensitization Inventory Scores in Participants with Chronic Musculoskeletal Pain: An Exploratory Study.

BACKGROUND: The Central Sensitization Inventory (CSI) is often used in clinical settings to screen for the presence of central sensitization. However, various cutoff scores have been reported for this tool, and scores have not been consistently associated with widespread pain sensitivity as measured with quantitative sensory testing (QST). The purpose of this study was to compare QST profiles among asymptomatic controls and participants with chronic musculoskeletal pain (CMP), and to determine the association between self-report questionnaires and QST in participants with CMP. METHODS: Twenty asymptomatic controls and 46 participants with CMP completed the CSI, PROMIS-29, and QST assessments of mechanical and thermal pain thresholds remote to the area of pain. Receiver Operating Characteristic analysis revealed a cutoff score of 33.5 for the CSI. PROMIS-29 Quality of Life (QOL) inventory and QST measures were compared between low and high CSI groups. RESULTS: The high CSI group (n = 19) had significantly lower mechanical and thermal pain thresholds, and larger impairments in QOL measures, compared to the low CSI group (n = 27) and asymptomatic controls. Participants with CSI scores < 33.5 presented similarly to asymptomatic controls. Anxiety, pain interference, and CSI scores demonstrated the highest number of significant associations to QST measures. CONCLUSION: A cutoff score of 33.5 on the CSI may be useful for discriminating widespread pain sensitivity and quality of life impairments in participants with CMP. Future studies should consider how the presence of high or low CSI may impact differential diagnosis, prognosis, and treatment responsiveness for patients with primary or secondary CMP.

Characteristics of Professional Physical Therapist Faculty and Doctor of Physical Therapy Programs, 2008-2017: Influences on Graduation Rates and First-Time National Physical Therapy Examination Pass Rates.

OBJECTIVE: Graduation rates and first-time National Physical Therapy Examination (NPTE) pass rates among Doctor of Physical Therapy (DPT) programs have ranged from 30% to 100% and 0% to 100% between 2008 and 2017, respectively. Prior studies on predictors of graduation rates and NPTE pass rates from DPT programs have used cross-sectional data and have not studied faculty data. This study sought to understand how trends in DPT faculty and program characteristics correlated with graduation rates and first-time NPTE pass rates. METHODS: This study was a retrospective panel analysis of yearly data from 231 programs between 2008 and 2017. Random effects models estimated the correlations between faculty and program characteristics regarding graduation rates and first-time NPTE pass rates. RESULTS: Graduation rates peaked when programs devoted 25% of faculty time, on average, to scholarship. The number of peer-reviewed publications was positively correlated with graduation rates; however, the trend was logarithmic, indicating a diminishing rise in graduation rates as the number of publications exceeded 1 per faculty full-time equivalent. Tenure-track status, faculty of color, and part-time faculty were all negatively correlated with first-time NPTE pass rates. However, these 3 trends are likely not meaningful, because the predicted rates of decline in pass rates were minimal. CONCLUSIONS: Faculty engagement in scholarly activities can positively influence graduation rates, but only up to a certain level of faculty time devoted to scholarship. IMPACT: This is the first study to provide data on the influence of faculty on DPT student outcomes and will help education programs develop strategies to improve those outcomes.

Short-term effects of two deep dry needling techniques on pressure pain thresholds and electromyographic amplitude of the lumbosacral multifidus in patients with low back pain - a randomized clinical trial.

Objectives: The purpose of this study was to compare the effects of deep dry needling (DN) with and without needle manipulation on pressure pain thresholds (PPTs) and electromyographic (EMG) amplitude of the lumbosacral multifidus (LM) in adults with low back pain (LBP). Methods: Participants were randomized into two treatment groups: with needle manipulation (n = 21) and without needle manipulation (n = 21). All participants received a single session of the assigned DN intervention. PPTs and EMG amplitude of the LM muscle were collected three times: before DN, immediately after DN, and one week after DN. Results: The needle manipulation group had a significantly greater increase in PPT immediately after the intervention and at the one-week follow-up as compared to the no needle manipulation group. The increase of PPT in the needle manipulation group was significant immediately after the intervention, and the increase remained significant at the one-week follow-up. However, there was no significant difference in EMG amplitude of the LM muscle between groups across the three time points. Discussion: Deep DN with needle manipulation appeared to reduce mechanical pressure sensitivity more than DN without manipulation for patients with LBP. Although a single session of DN could reduce pressure pain sensitivity, it may not be sufficient to improve LM muscle function. Level of Evidence: 1b. Trial registration numbers: NCT03970486.

Psychometric Properties of Pressure Pain Thresholds Measured in 2 Positions for Adults With and Without Neck-Shoulder Pain and Tenderness.

OBJECTIVE: The purpose of this study was to determine the psychometric properties of pressure pain threshold (PPT) testing in adults with and without neck-shoulder pain and tenderness and to compare the differences in PPT measurements between the seated and prone positions. METHODS: Thirty asymptomatic adults and 30 symptomatic patients with intermittent neck-shoulder pain and tenderness completed the study. A pressure algometer was used to assess PPTs at specific points on the middle deltoid, levator scapulae, and upper trapezius muscles of the dominant side of the asymptomatic individuals and the painful side of the patients. Four trials were performed on each muscle in both the seated and prone positions. To determine between-day reliability, a subset of the participants returned to repeat the testing. RESULTS: The intraclass correlation coefficients showed good to excellent within-session reliability and fair to excellent between-day reliability of PPT measurements in both the seated and prone positions for both groups. There were significant differences between groups for all muscles in both positions (P < .05) except for the upper trapezius muscle in the prone position. In addition, significant differences were found between the 2 testing positions for the middle deltoid and upper trapezius muscles in the symptomatic group and for the middle deltoid muscle in the asymptomatic group. CONCLUSION: The results of the study suggest that PPT testing could be useful for distinguishing individuals with and without neck-shoulder pain and tenderness. Further, the patient's position should be considered when testing PPT, specifically at the middle deltoid or upper trapezius muscles.

The effects of dry needling and neurodynamic exercise on idiopathic peripheral neuropathy: A case report.

A single patient (male, 67) with a medical diagnosis of idiopathic peripheral neuropathy (G60.9) was referred to physical therapy. The patient presented with signs and symptoms consistent with peripheral neuropathy, including bilateral single leg balance deficits, sensation impairments, and antalgic gait. Treatment consisted of dry needling (DN) with electrical stimulation and a home exercise program involving a neurodynamic exercise to be performed daily. Dry needling included the use of thin filiform needles to stimulate the underlying structures directed at eliciting a change within the tissues. The needles were left in situ and connected to an electrical stimulation unit. The neurodynamic exercise used in this case study was designed to target the distal branches of the sciatic nerve. The patient was directed to complete 3 sets of 10 repetitions in the slumped position and moving between ankle plantar flexion and dorsiflexion. The patient was treated for a total of 4 visits over a 5-week period. The Foot and Ankle Ability Measure (FAAM), Numeric Pain Rating Scale (NPRS), Romberg Test, and sensation testing were collected at baseline and then again after the 4th treatment. A Global Rating of Change (GROC) score was obtained at the end of treatment. After the 4th visit, functional self-report scores were not improved (93.75%-86.9% at completion), while NPRS decreased to 2 from a baseline rating of 4. The eyes closed portion of the Rhomberg balance test improved from 5 s on the right limb to 15 s and from 8 s to 20 s on the left limb. Sharp/dull sensation testing of the L4 dermatome also improved from 2 out of 5 correctly selected on the left lower limb to 5 out of 5. At the S1 level, sensation improved on the left lower limb from 2 out of 5 to 4 out of 5 and from 2 out of 5 on the right lower limb to 5 out of 5. The patient's GROC score was rated as quite a bit better (+5). The outcomes of this case study suggest that clinicians may consider the addition of DN with electrical stimulation and neurodynamic exercises to the treatment of this patient population given the sizeable and rapid improvements in pain, balance, and sensation testing following only 4 treatments.

Effects of tactile feedback on lumbar multifidus muscle activity in asymptomatic healthy adults and patients with low back pain.

BACKGROUND: Reduced lumbar multifidus (LM) muscle contraction has been observed in patients with low back pain (LBP). Clinicians often use various strategies to ensure LM activation, including tactile feedback and verbal instruction. However, the effects of tactile feedback on muscle activation have not been studied previously. Therefore, the purpose of this study was to investigate whether or not tactile feedback would increase LM muscle activity in adults with and without LBP. METHODS: Twenty asymptomatic adults and 20 patients with existing LBP completed the study. Two electromyographic (EMG) electrodes were applied to both sides of the LM at the L5 segment. EMG activity was collected three times at rest with and without tactile feedback, then five times during contralateral arm lifts with and without tactile feedback. The tactile feedback was applied by direct and continuous hand contact to the bilateral LM over the lumbosacral area. Lastly, two 5-second trials of maximum voluntary isometric contraction (MVIC) during a bilateral arm lift were performed. EMG activity collected at rest and during contralateral arm lifts was normalized to that collected during MVIC. Normalized EMG values of the right side of the asymptomatic group and the painful side of the LBP group were used for data analysis. RESULTS: Statistical analysis showed significantly decreased LM EMG activity with tactile feedback both at rest and during contralateral arm lifts compared to LM EMG activity without tactile feedback. There was no difference in LM EMG between the asymptomatic and the LBP groups. CONCLUSIONS: The results of the study showed that adding tactile stimulation to verbal instruction appeared to provide an inhibitory effect on LM activity in both asymptomatic healthy adults and patients with LBP. Contrary to common belief, tactical feedback via direct hand contact may reduce LM muscle recruitment, and may lessen the desired treatment effect.

Treatment of drug-resistant fibromyalgia symptoms using high-intensity laser therapy: a case-based review.

Fibromyalgia is a chronic musculoskeletal condition characterized by widespread pain in the body and is associated with tender points at the shoulder, back and hip regions. A wide variety of pharmacologic drugs and dietary supplements have been used with limited success in treating the musculoskeletal pain. Early clinical studies with low level laser therapy (LLLT) alone or in combination with drugs commonly used to treat fibromyalgia suggested that LLLT may be effective in reducing musculoskeletal pain and stiffness, as well as the number of tender locations. However, a sham-controlled study reported that LLLT was not significantly better than the sham treatment and kinesiotape. Preliminary studies with high-intensity laser therapy (HILT) suggest that it may be more effective than LLLT for treating chronic pain syndromes. Therefore, we evaluated low (1 W), intermediate (42 W) and high level (75 W) HILT in a woman with long-standing fibromyalgia syndrome which was resistant to both standard pharmacotherapy and treatment in an interdisciplinary pain management program. The patient received a series of treatments with a HILT device (Phoenix Thera-lase) at a wavelength of 1275 nm administered at both the paraspinous region and tender points in the shoulder and hip regions. Although the 1 W treatment produced minimal symptom relief, both the 42 and the 75 W treatments produced a dramatic reduction in her overall pain, improved quality of sleep, and increased her level of physical activity for 4-10 days after these treatment sessions. This case illustrates the potential beneficial effects of using higher power levels of HILT for patients with fibromyalgia syndrome who have failed to respond to conventional interdisciplinary treatment regimens.

Effects of different verbal instructions on change of lumbar multifidus muscle thickness in asymptomatic adults and in patients with low back pain.

BACKGROUND: Spinal stabilisation exercise has been shown to be effective in the rehabilitation of low back pain (LBP). Due to the isometric nature of spinal stabilisation exercise, manual therapists use various verbal instructions to elicit lumbar multifidus muscle contraction. OBJECTIVES: The purpose of this study was to assess whether or not three verbal instructions would alter muscle thickness of the lumbar multifidus muscle differently in asymptomatic individuals and patients with LBP. METHODS: Three verbal instructions were selected for this study: (1) swell the muscle underneath the transducer, (2) draw your belly button in towards your spinal column and (3) think about tilting your pelvis but without really doing it. Lumbar multifidus muscle thickness was determined using parasagittal ultrasound (US) imaging. Measurements of muscle thickness were collected at rest and during verbal instructions from 21 asymptomatic adults and 21 patients with LBP. Percent changes of muscle thickness during contraction and at rest were compared between groups and across verbal instructions. RESULTS: ANOVA results showed no significant interaction for both L4-5 and L5-S1, but a significant main effect of verbal instruction (P = 0.049) at L4-5.Post hoc analysis showed a greater increase with verbal instruction #3 than verbal instruction #2 (P = 0.009). There was no significant main effect of group at either segment. DISCUSSION: The results of the study suggest that both groups responded similarly to the three verbal instructions. Verbal instructions may increase lumbar multifidus muscle thickness by different amounts at L4-5, but by the same amount at L5-S1.

Immediate and lasting effects of a thoracic spine manipulation in a patient with signs of cervical radiculopathy and upper extremity hyperalgesia: A case report.

Patients with cervical radiculopathy (CR) may present with accompanying symptoms of hyperalgesia, allodynia, heaviness in the arm, and non-segmental pain that do not appear to be related to a peripheral spinal nerve. These findings may suggest the presence of central or autonomic nervous system involvement, requiring a modified management approach. The purpose of this case report is to describe the treatment of a patient with signs of CR and upper extremity (UE) hyperalgesia who had a significant decrease in her UE pain and hypersensitivity after a single thoracic spine manipulation (TSM). A 48-year-old female presented to physical therapy with acute neck pain radiating into her left UE that significantly limited her ability to sleep and work. After a single TSM, the patient demonstrated immediate and lasting reduction in hyperalgesia, hypersensitivity to touch, elimination of perceived heaviness and coldness in her left UE, and improved strength in the C6-8 myotome, allowing for improved functional activity capacity and tolerance to a multi-modal PT program. Based on these results, clinicians should consider the early application of TSM in patients with CR who have atypical, widespread, or severe neurological symptoms that limit early mobilization and tolerance to treatment at the painful region.

Reliability and Comparison of Spinal End-Range Motion Assessment Using a Skin-Surface Device in Participants With and Without Low Back Pain.

OBJECTIVE: The purposes of this study were to determine the reliability of using a skin-surface device to measure global and segmental thoracic and lumbar spine motion in participants with and without low back pain (LBP) and to compare global thoracic and lumbar motion between the 2 groups. METHODS: Forty participants were included in the study (20 adults with LBP and 20 age- and sex-matched adults without LBP). On the same day, 2 raters independently measured thoracic and lumbar spine motion by rolling a skin-surface device along the spine from C7 to S3, with participants at their end range of standing flexion and extension. RESULTS: In participants with LBP, global thoracic and lumbar flexion and extension end-range motion testing yielded fair-to-high intrarater reliability (intraclass correlation coefficient [ICC] = 0.76-0.96) and good-to-high interrater reliability (ICC = 0.82-0.98). Interrater reliability was fair to high (ICC = 0.77-0.93) for segmental lumbar flexion measurements in participants with LBP. No significant differences were found in global thoracic and lumbar flexion or extension end-range mobility between participants with and without LBP. CONCLUSIONS: Global thoracic and lumbar end-range motion measurement using a skin-surface device has acceptable reliability for participants with LBP. Reliability for segmental end-range motion measurement was only acceptable for lumbar flexion in participants with LBP.

Hip stiffness patterns in lumbar flexion- or extension-based movement syndromes.

OBJECTIVE: To determine whether a relationship exists between sagittal plane hip range of motion loss and sagittal plane lumbar Movement System Impairment (MSI) categories in patients with low back pain (LBP). DESIGN: Correlational study. SETTING: University outpatient physical therapy clinic. PARTICIPANTS: Subjects (N=40) with LBP. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Classification into a flexion- or extension-based lumbar MSI category, and bilateral passive hip flexion and extension range of motion testing. Using predefined criteria, subjects in each MSI category were subclassified into 1 of 3 hip stiffness categories: (1) a considerable loss of either flexion or extension (pattern A); (2) a considerable loss of both flexion and extension (pattern B); or (3) minimally limited flexion or extension (pattern C). RESULTS: Pattern A occurred in 23 (57.5%) subjects, with the primary direction of hip motion loss agreeing with the MSI category 78.3% of the time (φ=.56; P=.007). Pattern B occurred in 10 (25%) subjects, with the primary direction of hip motion loss agreeing with the MSI category 70% of the time (φ=.47; P=.197). Pattern C occurred in 7 (17.5%) subjects, with the primary direction of hip motion limitation agreeing with the MSI category 42.9% of the time (φ=-.40; P=.290). CONCLUSIONS: Considerable unidirectional hip motion loss in the sagittal plane was a common finding among subjects with LBP and yielded a strong positive relationship with the same direction MSI category. These results may inform future studies investigating whether treatment of hip stiffness patterns could improve outcomes in LBP management.
