Is there a paradoxical side effect? Is it a case of inefficiency? Peripheral ulcerative keratitis in a patient with rheumatoid arthritis in remission treated with tocilizumab.

Tocilizumab is a monoclonal antibody to interleukin-6 that has recently been used in rheumatoid arthritis (RA) treatment. Treatment with tocilizumab may be associated with paradoxical manifestations that are poorly understood. Patients that developed peripheral ulcerative keratitis while on tocilizumab treatment were studied in a case series. It was discovered that this could be a paradoxical side effect or ineffectiveness. Herein, we present a patient with seropositive RA who was followed for 22 years, using tocilizumab for seven years, and who developed peripheral ulcerative keratitis while in remission. Consequently, even in remission, extra-articular involvement can occur in RA patients, and medication-related paradoxical side effects can arise.

Does fear of activity predict exercise capacity in patients with coronary artery disease in both sexes? A cross-sectional multicenter study.

Objectives: This study aimed to identify whether fear of activity predicts exercise capacity in patients with coronary artery disease (CAD) and whether there is a difference between sexes regarding this relationship. Patients and methods: One hundred ninety-seven patients (145 males, 52 females; mean age: 56.3±10.8 years; range, 22 to 80 years) with a diagnosis of CAD or cardiac event in the previous one to 60 months were enrolled in this cross-sectional multicenter study between November 2015 and February 2017. Demographic and clinical features were recorded. Fear of activity was assessed by the fear of activity scale in patients with CAD (FactCAD). A 6-min walk test was used to assess exercise capacity. Results: Female participants were older, less educated, and less employed (p=0.045, p=0.048, and p<0.001, respectively) than males. Prevalence of myocardial infarction was higher in males. Comorbidities were higher in females. Multiple linear regression predicted 6-min walk distance (6MWD) based on FactCAD, sex, and education level with an r-squared of 0.321 (p<0.001). Fear of activity had an effect on walking distance in males (each additional score of FactCAD predicts a decrease of 1.3 m in 6MWD), together with disease duration, presence of chronic pulmonary disease, and low back pain, whereas fear of activity was not a predicting factor on walking distance in females. Age, education, and presence of angina predicted 6MWD in females. Conclusion: This study emphasizes that fear of activity is one of the predictors of 6MWD in males with CAD, and its assessment is recommended as a possible barrier to rehabilitation.

Clinical Evaluation of Balance in Children With Hemophilic Arthropathy.

Purpose: Hemophilia is a hereditary coagulation disorder characterized by acute hemorrhages into the musculoskeletal system, leading eventually to arthropathy and disability. Chronic inflammation of the synovial membrane arises as a result of frequent joint hemorrhage. Proteolytic enzymes in the blood and cartilage cause deterioration after that, and joint space narrows. Chronic hemophilic arthropathy develops as a result of these unfavorable developments, which occur more quickly, especially in the target joints. Balance is a process that allows us to maintain our orientation in three-dimensional space while also regulating our body posture to avoid falling. After the central nervous system evaluates deep stimuli from sensory, visual, and auditory receptors, movement of the corresponding muscle groups is delivered. Methods: The goal of this study was to investigate how impairment to deep sensory receptors (proprioception) in the arthropathic joint structure affected hemophiliacs' balance. The study comprised 34 patients with hemophilic arthropathy, and 34 age and weight matched healthy volunteers. Results: When balance tests of patients with hemophilic arthropathy were compared to healthy controls, hemophiliacs had a greater risk of falling. As the degree of arthropathy increased, so did the risk of falling and balance test values in individuals with hemophilic arthropathy. Conclusions: Treatment and coagulation factor prophylaxis to prevent the onset of arthropathy will improve patients' quality of life and reduce morbidity associated with frequent falls and bleeding.

Comparing the effectiveness of ultrasound guided versus blind genicular nerve block on pain, muscle strength with isokinetic device, physical function and quality of life in chronic knee osteoarthritis: a prospective randomized controlled study.

BACKGROUND: The genicular nerve block (GNB) is demonstrated from several reports to alleviate pain and improve knee functionality in patients with chronic knee osteoarthritis (OA). Ultrasound (US)-guided GNB has been the most used imaging method. This study aimed to compare the effectiveness of US-guided versus blind GNB in the treatment of knee OA. METHODS: This prospective, randomized clinical trial included patients with knee OA based on American College of Rheumatology diagnostic criteria. The patients were evaluated for clinical and dynamometer parameters at the baseline, 4 weeks after treatment, and 12 weeks after treatment. The patients underwent blind injection or US-guided injection. RESULTS: When compared with the baseline, both groups showed significant improvement in pain, physical function, and quality of life parameters. Significant differences were observed between the groups for clinical parameters (30-second chair stand test, 6-minute walk test) in favor of the US-guided group. On the other hand, blind injection was more significantly effective on some parameters of the Nottingham Health Profile. There wasn't any significant improvement in isokinetic muscle strength for either group. CONCLUSIONS: This study demonstrated that both US-guided and blind GNB, in the treatment of knee OA, were effective in reducing symptoms and improving physical function. GNB wasn't an effective treatment for isokinetic muscle function. USguided injections may yield more effective clinical results than blind injections.

Is kinesiophobia associated with lymphedema, upper extremity function, and psychological morbidity in breast cancer survivors?

OBJECTIVES: This study aims to the effects of kinesiophobia on lymphedema, upper extremity function, depression/anxiety, and quality of life in breast cancer survivors. PATIENTS AND METHODS: Between January 2015 and January 2016, a total of 81 breast cancer survivors (mean age 54.1±10.8 years; range 44 to 70 years) were included. Lymphedema was evaluated based on the circumference measurements. The Tampa Scale for Kinesiophobia (TSK), the Quick Disabilities of Arm, Shoulder, and Hand (Q-DASH) Questionnaire, the Hospital Anxiety and Depression Scale (HADS), and the Short Form-36 (SF-36) were applied to all patients. RESULTS: We found a significantly higher rate of lymphedema in the patients with kinesiophobia. Kinesiophobic patients had also significantly higher mean scores of TSK, Q-DASH, HADS-A, and HADS-D and lower mean scores of the SF-36 physical scores. Correlation analysis demonstrated that presence of lymphedema, Q-DASH, HADS-A, and HADS-D scores were significantly associated with the TSK scores. CONCLUSION: Kinesiophobia increases the risk for lymphedema, depression/anxiety, and decreased upper extremity functioning in breast cancer survivors. Identifying kinesiophobia in breast cancer survivors, psychosocial providers may help to prevent undesirable effects of kinesiophobia.

Spontaneous regression of extruded lumbar disc herniation: Correlation with clinical outcome.

OBJECTIVE: To evaluate the natural history of lumbar extruded disc with conservative treatment on MRI and to assess relation between the radiologic changes and clinical outcome. METHODS: This prospective observational study was conducted at University of Health Sciences, Diskapi Yildirim Beyazit Training and Research Hospital between May 2015-June 2018. It included consecutive patients who were diagnosed as having lumbar symptomatic extruded disc as shown in MRI. After an average period of 17.0±7.2 months, repeat MRI was taken in 40 patients who received only conservative care during follow-up. Changes in the volume of herniated disc was measured. The patients were assigned into 3 groups as follow: (1) non-regression, (2) partial-regression, and (3) complete resolution. Numeric Rating Scale (NRS) pain score, the Oswestry Low Back Pain Disability Index (ODI) and muscle weakness were evaluated. RESULTS: Based on disc volume of the T2-weighted MR images; four patients (10%) did not show any regression, six patients (15%) had a partial regression, and 30 patients (75%) had a complete resolution. Patients with complete resolution showed a significant improvement in the NRS pain score and the ODI score (p<0,001) over time. In patients with partial regression, only the ODI score improved significantly (p=0,043). Non-regression group did not show any improvement in any clinical outcome measure (p>0,05). Changes in the NRS scores over time were significantly higher in complete resolution group compared to non-regression group (p=0.016). CONCLUSION: The majority of the patients with extruded lumbar disc herniation might have reduction in size of herniated disc in the long run along with improvement in symptoms and function with conservative care.

The addition of self-lymphatic drainage to compression therapy instead of manual lymphatic drainage in the first phase of complex decongestive therapy for treatment of breast cancer-related lymphedema: A randomized-controlled, prospective study.

OBJECTIVES: The aim of this study was to investigate the effects of adding self-lymphatic drainage (SLD) to compression bandaging (CB) therapy rather than manual lymphatic drainage (MLD) in the first phase of complex decongestive therapy (CDT) on arm edema, quality of life, upper extremity function, and anxiety-depression in patients with breast cancer-related lymphedema (BCRL). PATIENTS AND METHODS: Between January 2015 and January 2017, a total of 24 patients (mean age 58.9±10.3 years; range, 42 to 83 years) with BCRL were randomly assigned to receive CB or CB plus SLD. The edema of the arm was assessed by volume calculation based on the circumference measurements. The Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire (Q-DASH) for upper extremity functions, the Short Form-36 health survey (SF-36) for the quality of life, and the Hospital Anxiety-Depression Scale (HADS) for anxiety and depression were used. The patients were assessed before the treatment, at the end of the treatment, and six months after the treatment. RESULTS: A significant volume decrease was observed in the affected arm in both groups at the end of the treatment. Statistically significant improvements in the SF-36 and Q-DASH scores were observed in both groups; however, there was no significant change in the HADS-anxiety and depression subscale scores. CONCLUSION: Our study results suggest that compression therapy with or without SLD is effective in the treatment of BCRL. However, the addition of SLD to CB in the first phase of CDT rather than MLD seems to provide no additional significant benefit.

Early Detection and Treatment of Subclinical Lymphedema in Patients with Breast Cancer.

Background: Early identification and treatment of subclinical lymphedema may prevent development of advanced stages and its related complications. We aimed to detect subclinical lymphedema and to evaluate the effects of early treatment program on the development of clinical lymphedema, upper extremity functions, and quality of life in patients with subclinical lymphedema. Methods and Results: Twenty-five women who were diagnosed having subclinical lymphedema were enrolled in the study. The patients were informed about lymphedema and its risk factors, and skin care and exercises to prevent the development of lymphedema. Self-reported symptoms, arm volumes, upper extremity functions, quality of life were evaluated before and after treatment. Tightness and numbness were found to have a good correlation with affected arm volume. Volume of the affected arm, percentage volume difference between the arms, upper extremity functions, and quality-of-life scores improved significantly at the end of the treatment. Conclusions: It is crucial to have early detection and treatment of subclinical lymphedema to prevent the development of established lymphedema in breast cancer survivors. Information about lymphedema and its risk factors, skin care, and home-based specific exercise program improves self-reported symptoms, volume measurements, functioning, and quality of life in patients with subclinical lymphedema.

Does hyperthermic preconditioning affect the rate of surgical site infection rate and inflammatory reaction in colorectal cancer patients? A prospective randomized clinical trial.

OBJECTIVE: Hyperthermic preconditioning has been shown to protect against different insults in experimental studies. However, clinical studies assessing its effects remain limited. The aim of this study was to investigate the effects of hyperthermic preconditioning on the rate of surgical site infection and inflammatory reaction in patients undergoing elective colorectal cancer surgery. MATERIAL AND METHODS: Patients with colorectal cancer, scheduled to undergo elective surgery were enrolled in this prospective randomized study. Patients were randomly assigned to either the hyperthermic preconditioning group or control group. Postoperative superficial and deep surgical site infection were recorded. Blood samples were collected from all the patients in the hyperthermic preconditioning group prior to the application of hyperthermia 12 h before surgery, immediately prior to surgery, and 4 h and 24 h postoperatively. For the control group, blood samples were obtained within the same periods without the application of hyperthermia. Levels of interleukin-1, IL-6, and tumor necrosis factor-α were measured from blood samples. RESULTS: Twenty patients were randomized to the hyperthermic preconditioning group and 21 to the control group. No significant difference was found in deep or superficial surgical site infection between the groups. No significant difference in the tumor necrosis factor-α, interleukin-1, and IL-6 levels was found in serum samples collected before hyperthermia, during the operation, and postoperatively. CONCLUSION: This study showed that hyperthermic preconditioning has no effect on the surgical site infection and cytokine response in patients undergoing elective surgical intervention for colorectal cancer.

Low back pain in hemodialysis patients: Risk factors and its impact on health-related quality of life.

OBJECTIVES: The aim of this study was to evaluate frequency and characteristics of low back pain and to identify possible risk factors of low back pain and its impact on health-related quality of life in hemodialysis patients. PATIENTS AND METHODS: A total of 87 hemodialysis patients (41 males, 46 females; mean age: 53.3±15.8 years; range, 21 to 80 years) were included in the study between January 2015 and July 2015. Medical charts and face-to-face interviews were used to collect clinical and demographic data. A comprehensive clinical evaluation of low back pain was implemented. The patients were divided into two groups: those with (n=32) and without (n=55) low back pain. Demographic data, quality of life, pain, and disability were compared between the groups. Pain severity was assessed using the Visual Analog Scale (VAS). Low back pain-associated disability was measured using the Oswestry Disability Index (ODI). Risk factors of low back pain were identified using multiple logistic regression analysis. The impact of low back pain on health-related quality of life was measured using the Nottingham Health Profile (NHP). RESULTS: Advanced age, increased body mass index, and smoking were found to be significant independent risk factors of low back pain (p=0.048; p=0.037; p=0.020, respectively). Energy, pain, and physical mobility subscale scores of the NHP were also higher in the hemodialysis patients with low back pain (p=0.008; p<0.001; p<0.001, respectively). Energy, pain, sleep, and physical mobility subscale scores of the NHP showed a significant positive correlation with the ODI scores (r=0.424, p=0.016; r=0.803, p<0.001; r=0.493, p=0.004; r=0.862, p<0.001, respectively). The etiology of low back pain was non-specific in the majority of the patients (71.9%). There were spondylodiscitis in two patients (6.2%), compression fractures in two patients (6.2%), spinal stenosis in one patient (3.1%), and discopathy in four patients (12.5%). CONCLUSION: Low back pain is a common condition in hemodialysis patients. Advanced age, increased body mass index, and smoking are the main risk factors of low back pain. The presence of low back pain is also related to poor health-related quality of life in hemodialysis patients.

Protracted febrile myalgia in a patient with Familial Mediterranean Fever and Ankylosing Spondylitis.

BACKGROUND: Protracted Febrile Myalgia is a rare form of vasculitis that is diagnosed in patients with Familial Mediterranean Fever. OBJECTIVE: To present a case with Familial Mediterranean and Anklosing Spondylitis on anti-TNF therapy for three years, who developed protracted febrile myalgia syndrome. METHODS: Case report. RESULTS: A 35-year-old woman with known Familial Mediterranean Fever and Anklosing Spondylitis for 3 years presented with fever, diarrhea, intermittent abdominal pain and severe diffuse muscular pain lasting for two weeks. The patient was investigated for any infection focus. The patient was diagnosed as having Protracted Febrile Myalgia four weeks after the onset of the symptoms. Prednisolone 1 mg/kg per day was applied. Her fever and muscle pain resolved within 48 hours. CONCLUSION: The coexisting Ankylosing Spondylitis disease and the use of anti-TNF treatment in patients with Familial Mediterranean Fever could be a confounding factor for the investigation of fever. Steroid therapy has a dramatic response.

Assessment of Risk Factors in Patients who presented to the Outpatient Clinic for Breast Cancer-Related Lymphedema.

OBJECTIVE: Lymphedema is one of the most debilitating outcomes of breast cancer treatment. We aimed to compare the demographic and clinical characteristics of breast cancer patients with and without lymphedema, to assess risk factors for lymphedema, and to evaluate treatment outcomes in lymphedema patients. MATERIALS AND METHODS: Demographic and clinical characteristics of 84 women with previous surgery for breast cancer who presented to the outpatient clinic between March 2014 and May 2015 were retrospectively extracted from patient records. RESULTS: Upper extremity lymphedema was detected in 34 of 84 patients (40.5%). The mean age, body mass index, the number of positive lymph nodes and the number of patients with postoperative radiotherapy were significantly higher among patients with lymphedema than those without (p<0.05). Educational level of patients with lymphedema was significantly lower than the other group (p<0.05). The correlation analysis revealed an association between age, educational level, body mass index, tumor stage, number of positive lymph nodes, postoperative radiotherapy and presence of lymphedema. Postoperative radiotherapy was detected as the only independent risk factor by logistic regression analysis. Fourteen out of 26 lymphedema patients were assigned to education, skin care, exercise and compression bandaging therapy. Upper extremity volumes and volume differences were significantly improved after treatment. CONCLUSION: Advanced age, low educational level, obesity, tumor size, the number of positive lymph nodes and postoperative radiotherapy correlated with the development of lymphedema. Within these factors, postoperative radiotherapy was detected as an independent risk factor for the development of lymphedema. Patient education, skin care, exercise and compression bandage therapy are effective treatment options in breast cancer-related lymphedema.

Femoral nerve injury after nephrectomy: A case report.

BACKGROUND: Femoral nerve injury is not a common complication of the abdominopelvic surgical procedures. OBJECTIVE: To present a case of femoral neuropathy after nephrectomy. METHODS: Case report. RESULTS: A 71-year-old female patient with a right-sided congenital hip dysplasia developed numbness, tingling and burning pain in the right thigh and muscle weakness in the right hip after the nephrectomy surgery. Neurological examination and electrodiagnostic test revealed a femoral nerve injury. Prognosis of the femoral neuropathy was good. The quadriceps muscle weakness improved within six months. CONCLUSION: Postoperative femoral neuropathy is an unexpected complication after total nephrectomy surgery. The prognosis is relatively good and early physical therapy can produce rapid recovery.

Hemiplegic shoulder pain: associated factors and rehabilitation outcomes of hemiplegic patients with and without shoulder pain.

OBJECTIVES: To analyze the incidence of and the factors associated with shoulder pain in people with hemiplegia and to understand the effect of rehabilitation programs on the parameters of motor function and activity limitations in patients with and without hemiplegic shoulder pain. METHODS: Patients in the initial 6-month period after stroke who were hospitalized in the physical medicine and rehabilitation clinic were included in the study. Patients were considered early rehabilitation entrants if they were admitted in the first 0 to 30 days after a stroke and late rehabilitation entrants if they were admitted 30 to 120 days after a stroke. Demographic and clinical features, complications, and medical histories of the patients were recorded. Upper extremity Fugl-Meyer Motor Assessment (FMA), Frenchay Arm Test (FAT), and Functional Independence Measure (FIM) were applied to the patients on admission, at discharge, and after 1 month of follow-up. RESULTS: Twenty-one (38%) patients did not have shoulder pain, and 34 (62%) patients had decreased shoulder pain. Immobilization, duration of disease, and late rehabilitation were shown to be effective treatments for shoulder pain. The major risk factors were disease duration and poor initial motor function. In both groups, the FMA, FAT, and FIM scores showed significant changes. This improvement did not differ between the 2 groups. CONCLUSION: Duration of disease and low motor functional capacities have the most important impact on shoulder pain. In patients with and without shoulder pain, a systematic rehabilitation program is beneficial with respect to motor function and daily living activities.

Distribution of Zonula Occludens-1 and Occludin and alterations of testicular morphology after in utero radiation and postnatal hyperthermia in rats.

In utero irradiation (IR) and postnatal hyperthermia (HT) exposure cause infertility by decreasing spermatogenic colony growth and the number of sperm in rats. Four groups were used: (i) Control group, (ii) HT group (rats exposed to hyperthermia on the 10th postnatal day), (iii) IR group (rats exposed to IR on the 17th gestational day) and (iv) IR + HT group. Three and six months after the procedures testes were examined by light and electron microscopy. Some degenerated tubules in the HT group, many vacuoles in spermatogenic cells and degenerated tight junctions in the IR group, atrophic tubules and severe degeneration of tight junctions in the IR + HT group were observed. ZO-1 and occludin immunoreactivity were decreased and disorganized in the HT and IR groups and absent in the IR + HT group. The increase in the number of apoptotic cells was accompanied by a time-dependent decrease in haploid, diploid and tetraploid cells in all groups. Degenerative findings were severe after 6 months in all groups. The double-hit model may represent a Sertoli cell only model of infertility due to a decrease in spermatogenic cell and alterated blood-testis barrier proteins in rat.

Morphological alterations and distribution of occludin in rat testes after bilateral vasectomy.

The aim of study was to investigate the fate and the morphology of the cells which constitute the spermatogenic line, and to determine the distribution of occludin in the testis in adult vasectomized Wistar rats. The rats were divided into two groups: control group (sham-operated) and vasectomized group. One, 3 and 6 months after sham and vasectomy operations, testis samples were examined. The weight of the testes was found to be reduced 3 and 6 months after vasectomy. There was vacuolization in the seminiferous tubules one month after vasectomy. The tubules showed severe atrophy 3 and 6 months after vasectomy. The occludin immunolabeling in the 3- and 6-month groups was weak and diffuse, and the density of the protein was found to be decreased. The increase in the number of apoptotic cells was accompanied by a time-dependent decrease in the number of haploid, diploid and tetraploid cells. This study demonstrated that vasectomy causes degeneration in the seminiferous tubules with alterations in occludin distribution with a decrease in the number of spermatogenic cells. Moreover, these alterations increase in a time-dependent manner.

Quality of life in patients with spinal cord injury.

The primary objective of this study was to assess the quality of life (QoL) in spinal cord injury (SCI) survivors. Secondary objectives were to determine the effects of various sociodemographic and clinical characteristics on QoL. This cross-sectional study included 54 patients with SCI. The Turkish version of the Short-Form-36 Health Survey was used to assess health-related QoL. Functional status was measured with Functional Independence Measure. Higher values were obtained in younger individuals for bodily pain, in paraplegic patients for physical functioning, role-physical, social functioning, and role-emotional. Moreover, it was observed that functional status correlated well with physical functioning, role-physical, social functioning, and role-emotional. Among the complications investigated, bladder incontinence is related to low health-related QoL in most domains. SCI may interfere with some health domains of QoL according to the patient's age, neurologic levels, functional status and presence of complications, mainly bladder incontinence.

Functional and clinical evaluation for the surgical treatment of degenerative stenosis of the lumbar spinal canal.

OBJECT: This study was designed to evaluate the efficacy of decompressive surgery for degenerative lumbar spinal stenosis (LSS) on a functional and clinical basis. METHODS: A prospective analysis and follow-up of 125 consecutive patients with degenerative LSS between 2000 and 2006 were performed. All patients underwent surgery for lumbar stenosis. Functional evaluations of the patients were performed using a treadmill, the visual analog scale, and the Oswestry Disability Questionnaire (ODQ). These parameters were recorded before surgery and the 3rd month and 1st and 2nd years after treatment. The first symptom time (FST), maximal walking duration (MWD), and thecal sac cross-sectional area (CSA) before and after surgery were also recorded. Statistical relations between variables were calculated. RESULTS: As patient ages increased, the CSA of the thecal sac decreased. Decompressive surgery reached the target according to the difference between the preoperative and postoperative thecal sac CSA. A correlation between the CSA of the thecal sac and FST, and between the CSA of the thecal sac and MWD could not be established. There was a significant correlation between the FST and MWD, and a negative correlation could be established between the MWD and the ODQ score. Surgery led to significant decreases in the ODQ score. Maximal improvement was observed in the 3rd month after decompressive surgery. CONCLUSIONS: The treatment for LSS should be decided using functional criteria; radiological criteria may not correlate with the severity of the disease. Improvements following lumbar decompression surgery continued within 1 year of treatment according to the ODQ and did not change significantly thereafter.

Acute low back pain: clinical course and prognostic factors.

PURPOSE: The aim of this study was to assess the clinical course of patients with acute low back pain (LBP) throughout 12 weeks and to identify the prognostic factors for non-recovery in the short term. METHOD: A total of 91 patients with acute LBP (<3 weeks) were included in this study. Baseline assessments including demographic variables, clinical characteristics of pain, lost work time and results of clinical examination were noted. Pain intensity, disability, general health perception and depression were assessed according to visual analogue scale, Roland Morris Disability Questionnaire (RMDQ), Nottingham Health Profile (NHP) and Beck Depression Inventory, respectively. Patients were assessed for pain intensity and disability at baseline, and at 1, 2, 4, 8 and 12 weeks of follow-up. Recovery was considered if patients scored <4 on the RMDQ and pain had resolved. At the 2nd week of follow-up, patients were divided into two groups according to recovery (Group 1) or non-recovery (Group 2) to identify the prognostic factors, which were analysed by multiple logistic regression. RESULTS: At 2 weeks, 52 (57.1%) of the patients had recovered and only eight (8.7%) developed chronic LBP. Mean pain intensity and mean disability scores dropped 96.7 and 96.4%, respectively, of initial levels during the 12 weeks. Sixty per cent of 63 employed patients reported lost time from work. A comparison between groups revealed that finger-floor distance, RMDQ and NHP (pain, physical mobility, emotional reactions, sleep, energy level, and distress subgroups) were statistically significantly lower in Group 1, and NHP-pain was strongly associated with non-recovery in the short term. CONCLUSIONS: Acute LBP patients with disability generally recover in the first weeks. General health perception (NHP) - pain subgroup score was identified in particular as the best prognostic factor for non-recovery in the short term. Hence, pain should be given particular consideration in baseline assessments of acute LBP patients.

Low-level laser therapy in subacromial impingement syndrome.

BACKGROUND DATA AND OBJECTIVE: Although previous studies have evaluated the effect of different kinds of physical therapy in subacromial impingement syndrome (SIS), there have been few investigations assessing the effectiveness of low-level laser therapy (LLLT) in shoulder disorders. The goal of this prospective randomized study was to assess whether gallium-arsenide (Ga-As) laser therapy improves the outcome of a comprehensive home exercise program in patients with SIS. MATERIALS AND METHODS: Forty-four newly-diagnosed SIS patients were enrolled in this study. Group 1 patients (n = 22) received Ga-As laser therapy combined with a 12-wk comprehensive home exercise program, and group 2 patients (n = 22) received the same 12-wk comprehensive home exercise program alone. Night pain, shoulder pain and disability index (SPADI), and University of California-Los Angeles end-result (UCLA) scores were used as outcome measures. RESULTS: Both groups showed a significant reduction in night pain and SPADI scores at the second and 12th weeks with respect to baseline values, with the exception of the SPADI total score at the second week in group 1. UCLA results improved significantly in both groups at the 12th in comparison to the second week. There were no significant differences between groups in mean actual changes in night pain and SPADI scores at the second week from baseline. When values at the 12th week were compared to baseline, mean actual changes in night pain differed significantly between the groups, with a larger change in group 1, but there was no difference between groups in mean actual change in SPADI scores. Second- and 12th-week UCLA scores did not differ between the two groups. CONCLUSION: Our study was unable to demonstrate any distinct advantage of low-level laser therapy over exercise alone. Comprehensive home exercise programs should be the primary therapeutic option in the rehabilitation process in SIS.
