The Clinical Efficacy of Low-Power Laser Therapy on Pain and Function in Cervical Osteoarthritis

Abstract: Pain is a major symptom in cervical osteoarthritis (COA). Low-power laser (LPL) therapy has been claimed to reduce pain in musculoskeletal pathologies, but there have been concerns about this point. The aim of this study was to evaluate the analgesic efficacy of LPL therapy and related functional changes in COA. Sixty patients between 20 and 65 years of age with clinically and radiologically diagnosed COA were included in the study. They were randomised into two equal groups according to the therapies applied, either with LPL or placebo laser. Patients in each group were investigated blindly in terms of pain and pain-related physical findings, such as increased paravertebral muscle spasm, loss of lordosis and range of neck motion restriction before and after therapy. Functional improvements were also evaluated. Pain, paravertebral muscle spasm, lordosis angle, the range of neck motion and function were observed to improve significantly in the LPL group, but no improvement was found in the placebo group. LPL seems to be successful in relieving pain and improving function in osteoarthritic diseases.

The evaluation of quality of life in fibromyalgia syndrome: a comparison with rheumatoid arthritis by using SF-36 Health Survey

Musculoskeletal disorders are the most common causes of deterioration in quality of life (QOL). We in this study aimed to assess (1) the impact of fibromyalgia syndrome (FS) on QOL comparing with that of rheumatoid arthritis (RA) patients and control subjects and (2) the impact of these two musculoskeletal disorders on various components of QOL using SF-36 Health Survey. Thirty-five patients with RA, 30 patients with FS, and 30 voluntary control subjects were included in the study. The groups were comparable in terms of demographic characteristics. QOL was evaluated by using Short-Form (SF)-36 Health Survey in all study participants, and Fibromyalgia Impact Questionnaire (FIQ), which is a specific health-status instrument for FS, was used in FS patients. Physical functioning, physical role, social functioning, bodily pain, general health, vitality, emotional role, and mental health scores were significantly lower in RA and FS patients than in control subjects (p<0.05). The between-groups comparisons revealed that FS patients had significantly lower mental health scores than RA patients (49.87 vs 62.51, respectively), (p<0.001). Total FIQ score correlated significantly with physical functioning, physical role, and bodily pain in FS patients. All parameters of SF-36 Health Survey except for social functioning correlated significantly with some of the variables of FIQ. FS has a negative impact on QOL, like RA. Furthermore, mental health was more severely affected in FS patients when compared with RA patients.

Cognitive evaluation and functional outcome after stroke.

Özdemir F, Birtane M, Tabatabaei R, Ekuklu G, Kokino S: Cognitive evaluation and functional outcome after stroke. Am J Phys Med Rehabil 2001;80:410–415. ObjectiveTo investigate the initial overall cognitive ability and its components as a predictor of functional improvement and ambulation during rehabilitation. Initial cognitive status is widely known to be a predictive factor in functional recovery in patients with stroke although some reports have found no such relationship. DesignBaseline cognitive status was scored by Minimental State Examination and its subsections with such headings as “orientation,” “registration,” “attention and calculation,” “recall,” and “language” in 43 patients with postacute stroke, aged between 51 and 68 yr. Function was evaluated in terms of motor FIMTM and functional ambulation as categorized in “Adapted Patient Evaluation and Conference System” functional scale at the time of admission and discharge. ResultsOnly total baseline Minimental State Examination score showed a significant correlation with discharge motor FIM improvement (r = 0.31, P = 0.04) and baseline orientation score correlated significantly with functional ambulation score improvement (r = 0.31, P = 0.03). In stepwise linear regression model, the same variables had an effect on similar outcome parameters. ConclusionsCognitiveion evaluation should be taken as a whole to predict functional outcome in patients with postacute stroke, except for the baseline orientation score that seemed more predictive for ambulation.

Pedobarography and its relation to radiologic erosion scores in rheumatoid arthritis

ObjectiveThe aim of this study was to assess probable plantar pressure alterations in rheumatoid arthritis (RA) patients by comparison with normal subjects and to investigate the probable relation between pressure distribution under the foot and radiologic foot erosion score.MethodsTwo hundred feet of 50 chronic RA patients and 50 healthy controls were evaluated. Static and dynamic pedobarographic evaluations were used to define the plantar pressure distribution. Also, the modified Larsen scoring system was used to detect the staging of erosions on feet radiograms of the RA patients.ResultsStatic pedobarography revealed higher pressure and contact areas in the forefoot. All dynamic pedobarographic parameters except for plantar contact area were significantly different between the RA patients and control subjects. Patients with high erosion scores had higher static forefoot and dynamic phalanx peak pressure values.ConclusionPedobarographic investigation can be useful to evaluate pressure distribution disorders in RA feet and may provide suitable guidelines for the design of various plantar supports.

Effectiveness of pulsed electromagnetic field therapy in lateral epicondylitis

We aimed to investigate the efficacy of pulsed electromagnetic field (PEMF) in lateral epicondylitis comparing the modality with sham PEMF and local steroid injection. Sixty patients with lateral epicondylitis were randomly and equally distributed into three groups as follows: Group I received PEMF, Group II sham PEMF, and Group III a corticosteroid + anesthetic agent injection. Pain levels during rest, activity, nighttime, resisted wrist dorsiflexion, and forearm supination were investigated with visual analog scale (VAS). Pain threshold on elbow was determined with algometer. All patients were evaluated before treatment at the third week and the third month. VAS values during activity and pain levels during resisted wrist dorsiflexion were significantly lower in Group III than Group I at the third week. Group I patients had lower pain during rest, activity and nighttime than Group III at third month. PEMF seems to reduce lateral epicondylitis pain better than sham PEMF. Corticosteroid and anesthetic agent injections can be used in patients for rapid return to activities.

Discriminative Value of Tender Points in Fibromyalgia Syndrome

OBJECTIVE The aim of this study is to assess the discriminative value of all tender points, alone and in combination, that are designated as criteria for fibromyalgia diagnosis by the American College of Rheumatology (ACR), by investigating the appropriate pressure magnitude that should be applied during tenderness examination. DESIGN Cross-sectional. PATIENTS This study was performed on 66 patients with fibromyalgia diagnosed according to ACR classification criteria and 50 control subjects. SETTING The outpatient rheumatology clinic of a PM&R department of a university hospital. Intervention. Pressure pain threshold values were measured by a dolorimeter on nine specific point pairs in both groups and a cutoff value for discriminating positivity and negativity was calculated for each. Then the most valuable tender point pairs were assessed for discrimination of fibromyalgia syndrome using ACR criteria set as a reference standard. RESULTS All tender points with determined pressure cutoff values were found out to significantly discriminate fibromyalgia syndrome and their area under curve values ranged from 0.779 to 0.934. Univariate logistic regression analysis revealed that lateral epicondyle and supraspinatus point pairs had the most powerful discriminative ability (odds ratio = 113.6 and 45.0, respectively). Multiple logistic regression analysis with backward stepwise method showed that lateral epicondyle and second rib point pairs were most discriminative with sensitivity and specificity rates of 87.9-94.0% and 77.3-84.0%, respectively. CONCLUSIONS Fibromyalgia syndrome can have potential to be recognized simply by pressing fewer tender point areas but with various pressure cutoff levels identified for each tender point areas.

Does quantitative tibial ultrasound predict low bone mineral density defined by dual energy X-ray absorptiometry?

Purpose Efforts for the early detection of bone loss and subsequent fracture risk by quantitative ultrasound (QUS), which is a non-invasive, radiation free, and cheaper method, seem rational to reduce the management costs. We aimed in this study to assess the probable correlation of speed of sound (SOS) values obtained by QUS with bone mineral density (BMD) as measured by the gold standard method, dual energy X-ray absorptiometry (DEXA), and to investigate the diagnostic value of QUS to define low BMD. Materials and Methods One hundred twenty-two postmenopausal women having prior standard DEXA measurements were included in the study. Spine and proximal femur (neck, trochanter and Wards triangle) BMD were assessed in a standard protocol by DEXA. The middle point of the right tibia was chosen for SOS measurement by tibial QUS. Results The SOS values were observed to be significantly higher in the normal BMD (t score > - 1) group at all measurement sites except for the lumbar region, when compared with the low BMD group (t score < - 1). SOS was negatively correlated with age (r = - 0.66) and month since menopause (r = - 0.57). The sensitivity, specificity, and positive and negative predictive values for QUS t score to diagnose low BMD did not seem to be satisfactory at either of the measurement sites. Conclusion Tibial SOS was correlated weakly with BMD values of femur and lumbar spine as measured by DEXA and its diagnostic value did not seem to be high for discriminating between normal and low BMD, at these sites.

The efficacy of linear polarized polychromatic light on burn wound healing : An experimental study on rats

We aimed to investigate the questionable effect of linear polarized polychromatic light on burn wound healing in rats. Two deep second-degree burn wounds on the backside of each of 21 Sprague-Dawley rats were created with a standard burning procedure by applying a heated plaque. Burned regions located right dorsolaterally and classified as group I lesions were treated with linear polarized polychromatic light + open dressing + antibacterial pomade, whereas group II lesions were located left dorsolaterally and treated with only open dressing + antibacterial pomade. Macroscopic evaluation was performed for determination of the completed wound closure rate, measurement of burn wound area, and investigation of macroscopic edema, hyperemia, and epithelialization. Histopathological evaluation included monitoring of epithelialization, vascularization, origination of granulation tissue, inflammatory cell response, and total histopathological score on days 7, 14, and 21 after burn creation. Macroscopic evaluation revealed more obvious epithelialization in group I lesions between days 6 and 15. The number of completely closed wounds was higher in group I than in group II on days 16 and 21. The average area of burn wounds was lower from day 5, hyperemia was less on days 2 to 17, and edema was less from day 4 to day 13 in group I lesions. Histopathological evaluation revealed a higher rate of epithelialization on day 7 and higher vascularization occurrence on day 21 in group I lesions. Linear polarized polychromatic light seems to be effective in the treatment of burn wounds and in the promotion of healing. This may be related to linear polarized polychromatic light stimulation of epithelialization and vascularization.

99mTc-sestamibi muscle scintigraphy to assess the response to neuromuscular electrical stimulation of normal quadriceps femoris muscle.

ObjectivesNeuromuscular electrical stimulation (NMES) is widely used for improving muscle strength by simultaneous contraction in the prevention of muscle atrophy. Although there exist many clinical methods for evaluating the therapeutic response of muscles,99mTc-sestamibi which is a skeletal muscle perfusion and metabolism agent has not previously been used for this purpose. The aim of our work was to ascertain whether99mTc-sestamibi muscle scintigraphy is useful in the monitoring of therapeutic response to NMES in healthy women.MethodsThe study included 16 women aged between 21 and 45, with a mean age of 32.7±6.4. Both quadriceps femoris muscles (QFM) of each patient were studied. After randomization to remove the effect of the dominant side, one QFM of each patient was subjected to the NMES procedure for a period of 20 days. NMES was performed with an alternating biphasic rectangular current, from a computed electrical stimulator daily for 23 minutes. After measurement of skinfold thickness over the thigh, pre- and post-NMES girth measurements were assessed in centimeters. Sixty minutes after injections of 555 MBq99mTc-sestamibi, static images of the thigh were obtained for 5 minutes. The thigh-to-knee uptake ratio was calculated by semiquantitative analysis and normalized to body surface area (NUR=normalized uptake ratio).ResultsThe difference between the pre and post NMES NUR values was significant (1.76±0.31 versus 2.25±0.38, p=0.0000). The percentage (%) increase in NUR values also well correlated with the % increase in thigh girth measurements (r=0.89, p=0.0000).ConclusionThese results indicated that99mTc-sestamibi muscle scintigraphy as a new tool may be useful in evaluating therapeutic response to NMES.

Risk of falls in patients with ankylosing spondylitis.

BackgroundRisk of vertebral fractures is increased in patients with ankylosing spondylitis (AS). The underlying mechanisms for the elevated fracture risk might be associated with bone and fall-related risks. The aims of this study were to evaluate the risk of falls and to determine the factors that increase the risk of falls in AS patients. MethodsEighty-nine women, 217 men, a total of 306 AS patients with a mean age of 40.1 ± 11.5 years from 9 different centers in Turkey were included in the study. Patients were questioned regarding history of falls within the last 1 year. Their demographics, disease characteristics including Bath AS Disease Activity Index, Bath AS Metrology Index (BASMI), Bath AS Functional Index (BASFI), and risk factors for falls were recorded. The Short Physical Performance Battery (SPPB) test was used for evaluation of static and dynamic balance. Erythrocyte sedimentation rate, C-reactive protein, and 25-hydroxyvitamin D levels were measured. ResultsForty of 306 patients reported at least 1 fall in the recent 1 year. The patients with history of falls had higher mean age and longer disease duration than did nonfallers (P = 0.001). In addition, these patients’ BASMI and BASFI values were higher than those of nonfallers (P = 0.002; P = 0.000, respectively). We found that the patients with history of falls had lower SPPB scores (P = 0.000). We also found that the number of falls increased with longer disease duration and older age (R = 0.117 [P = 0.041] and R = 0.160 [P = 0.005]). Our results show that decreased SPPB scores were associated with increased number of falls (R = 0.183, P = 0.006). Statistically significant correlations were found between number of falls and AS-related lost job (R = 0.140, P = 0.014), fear of falling (R = 0.316, P = 0.000), hip involvement (R = 0.112, P = 0.05), BASMI (R =0.234, P = 0.000), and BASFI (R = 0.244, P = 0.000). ConclusionsAssessment of pain, stiffness, fatigue, and lower-extremity involvement as well as asking for a history of falls will highlight those at high risk for further falls. In addition to the general exercise program adopted for all patients, we suggest that a balance rehabilitation program should be valuable for the patients with risk factors for fall. Exercise may improve fear of falling and BASFI and BASMI scores. However, further study is needed to investigate these hypotheses. We believe that clinicians should train and support the patients via reducing fear of falls and maintaining good posture and functional capacity.
