Effects of Kinesthesia and Balance Exercises in Knee Osteoarthritis

Background:In patients with knee osteoarthritis (OA), there is a prominent loss in proprioception and kinesthesia sensation compared with control subjects of the same age and gender. Objectives:The aim of this study is the investigation of short-term clinical effects of kinesthesia and balance exercises in patients with knee OA. Methods:This 8-week study was conducted on 66 female patients with knee OA who were randomized into 2 groups. The first group received kinesthesia and balance exercises (such as retrowalking, walking on their toes, leaning to the sides, balance board exercises, minitrampoline exercises, plyometric exercises, and so on) in addition to strengthening exercises. The second group received only strengthening exercises. Results:Statistically significant improvements were observed postexercise for both groups with respect to baseline for WOMAC, SF-36 Form, times for performing activities of daily living, isokinetic quadriceps muscle strength, and proprioceptive sensation levels. In the first group with kinesthesia training, compared with the second group, significantly greater improvements were obtained in all the subparameters that measure functional status (WOMAC–physical function value, SF-36 Form [physical function, role limitations–physical and vitality–energy or fatigue variables], 10 stairs climbing, and 10-m walking times) and in isokinetic muscle strength at high angular velocities (P < 0.05). The absolute angular error percentage (to assess proprioceptive accuracy) was significantly improved postexercise in both groups. There were no differences between the groups. Conclusions:Additive positive effects of kinesthesia and balance exercises in knee OA have been demonstrated. Used in clinical applications, they should be able to increase the functional capacities of patients. Long-term studies about efficacy and cost-effectivity of these exercises are needed.

The effectiveness of intensive group exercise on patients with ankylosing spondylitis

Objective: To compare, in patients with ankylosing spondylitis (AS), the effectiveness on pain, functional and psychological status of an intensive group exercise programme under the supervision of a physiotherapist and a home physiotherapy programme. Design: Fifty-one patients with AS were randomly allocated into study and control groups. The study was designed as a prospective, double-blind study. Setting: Outpatient department, Istanbul Medical Faculty. Subjects: Patients who consulted with complaints of pain, morning stiffness and restricted range of movement with a confirmed diagnosis of ankylosing spondylitis. Interventions: Before exercise, both groups were given an education programme about AS. For group I patients an intensive exercise programme was organized under the supervision of a physiotherapist for six weeks. Group II patients had to practise exercises individually at home. Main outcome measures: Both groups were evaluated and compared for pain, functional and psychological status before treatment, at the end of treatment and three months after treatment using a visual analogue scale (VAS) for pain, Beck Depression Scale and Bath Ankylosing Spondylitis Functional Index (BASFI). Results: Six patients withdrew, four from group I. Results from the remaining 45 showed more positive changes in the patients undertaking group exercise at six weeks and three months after treatment. Values showed a statistical significant difference in favour of group I. Conclusion: Group exercise in hospital may be more effective than home-based exercises at reducing impairment associated with ankylosing spondylitis.

Effectiveness of dry needling for the treatment of temporomandibular myofascial pain: A double-blind, randomized, placebo controlled study

BACKGROUND AND OBJECTIVES To test the hypothesis that dry needling is more effective than sham dry needling in relieving myofascial pain of the temporomandibular muscles. MATERIAL AND METHOD Fifty-two subjects with established myofascial trigger points were randomized into two groups; study group (N: 26) and placebo group (N: 26). Dry needling was applied using acupuncture needles. Sham dry needling was applied to the placebo group. Pain pressure threshold was measured with pressure algometry, pain intensity was rated using a 10-cm visual analog scale (VAS) and the unassisted jaw opening without pain measurement was performed. Evaluations were done by a physician blinded to the data. RESULTS Of 52 patients assigned, 50 completed the study. Mean algometric values were significantly higher in the study group when compared to the placebo group (p values being less than 0.05). There were no differences between the two groups in terms of VAS and unassisted jaw-opening without pain values. CONCLUSION Dry needling appears to be an effective treatment method in relieving the pain and tenderness of myofascial trigger points.

Evaluation of Needle Positioning During Blind Intra-Articular Hip Injections for Osteoarthritis: Fluoroscopy Versus Arthrography

UNLABELLED Diraçoğlu D, Alptekin K, Dikici F, Balci HI, Ozçakar L, Aksoy C. Evaluation of needle positioning during blind intra-articular hip injections for osteoarthritis: fluoroscopy versus arthrography. OBJECTIVE To evaluate needle positioning during blind/anatomically referenced hip joint injections for osteoarthritis (OA). DESIGN Experimental clinical study. SETTING Operating theater of a university hospital. PARTICIPANTS Patients (N=16) (10 women, 6 men), who were diagnosed as having OA according to the American College of Rheumatology criteria and whose radiologic grades were II or III according to Kellgren-Lawrence. INTERVENTIONS Three bilateral and 13 unilateral hip injections were performed (3 times at 1-week intervals). After it was presumed blindly that the needle was within the joint, the location of the needle was checked with backflow technique and fluoroscopy. Entrance to the joint cavity was also ensured by reconfirmation with contrast medium, and the procedure was then terminated with hyaluronic acid injection. MAIN OUTCOME MEASURES Assessment of blind needle placement into the hip joint by using backflow technique, fluoroscopic images, and contrast enhancement. RESULTS The location of the needle was fluoroscopically confirmed to be at the proper position in 38 (66.7%) of the 57 blind interventions. Furthermore, in 29 (76.3%) of those 38 interventions, localization of the intra-articular needle could be confirmed by intra-articular contrast uptake. Overall, 29 of 57 (50.9%) blind interventions exhibited intra-articular contrast enhancement. Backflow was not observed in 23 (79.3%) of these 29 interventions. Five (17.9%) of 28 interventions with no contrast uptake showed backflow. CONCLUSIONS In light of our results, we suggest that blind injection of the osteoarthritic hip joint can be inaccurate even with careful technique. Further, the backflow method does not appear to be reliable, and guidance during the injection seems to be necessary.

The effect of viscosupplementation on neuromuscular control of the knee in patients with osteoarthritis.

OBJECTIVE The aim of this study was to investigate the short-term effects of intra-articular injection of hyaluronan (Hylan G-F 20) on proprioception, isokinetic muscle force, self reported pain, and functional condition in patients with knee osteoarthritis (OA). METHODS 63 patients with stage II-III bilateral knee OA were included in this randomized, placebo controlled, and prospective study. Subjects were randomized with 42 of them into the treatment group and 21 of them into the placebo group. Hyaluronan was intraarticularly injected into both knees of the subjects which were in the treatment group, whereas physiological saline was intraarticularly injected to the subjects which were in the placebo group. Proprioception and the isokinetic muscle force measurement were performed. Visual analogue scale (VAS) and WOMAC scale were used to evaluate pain and physical function. RESULTS Statistical analysis was performed on 120 knees of 60 patients completing the trial. The average absolute angular error (AAAE) value showing the proprioceptive error level in the treatment group was detected to be statistically significantly lower compared to placebo at the measurements performed after the 3rd injection (p = 0.02) and after one week (p = 0.01). While there was no inter-group difference in isokinetic measurements performed at 180 and 240 degrees/sec, a significant difference was detected at the measurement performed at 60 degrees/sec in favor of the treatment group (p = 0.02). Activity and resting VAS-pain values, WOMAC parameters (except the WOMAC stiffness) were detected to be significantly lower in the treatment group. Local adverse events were not reported in any patient. CONCLUSION In this study, it was demonstrated that intraarticular injection of hyaluronan in patients with knee OA led to a short-term increase in proprioception and isokinetic muscle force, and also significant improvements in the functional conditions of patients. Long-term studies are needed.

Arthrocentesis versus nonsurgical methods in the treatment of temporomandibular disc displacement without reduction

OBJECTIVE The aim was to compare the short- and medium-term results of arthrocentesis and conventional treatment (splint, heat, and exercise) in patients with early temporomandibular joint (TMJ) disc displacement without reduction (DDw/oR). STUDY DESIGN One hundred twenty consecutive patients (104 female, 16 male), who had been followed by a multidisciplinary TMJ unit with the diagnosis of DDw/oR were enrolled in this single-blind prospective study. Patients either underwent arthrocentesis or they were given a combination of splint, hot pack, and home exercise program. Visual analog scale (VAS) was used for pain assessment. Maximal mouth opening (MMO), lateral movement, and protrusion were measured. Repeat measurements were performed on the first, third, and sixth months following treatments. RESULTS Arthrocentesis group consisted of 54 individuals (51 female, 3 male), and the conventional treatment group consisted of 56 individuals (49 female, 7 male). The mean age values of the groups were 33.4 years (range 15-63 years) and 34.8 years (range 17-61 years), respectively. Baseline VAS and MMO values of the arthrocentesis and conventional treatment groups were similar (P > .05). Regarding VAS and MMO, lateral movement, and protrusion, the intragroup analyses showed a statistically significant reduction in both groups compared with baseline values (all P < .01). Regarding VAS values, the difference values between each evaluation and the baseline measurement were significantly higher in the arthrocentesis group, except for the first-month difference. Regarding MMO, lateral movements, and protrusion, the differences between the baseline values and each evaluation thereafter were statistically similar between the 2 groups (P > .05). CONCLUSION We conclude that early treatment either with conservative methods or with arthrocentesis is beneficial in DDw/oR. However, arthrocentesis seems to be superior regarding pain management. Therefore, arthrocentesis may be indicated in patients where painful complaints overwhelm despite other conservative treatments.

The utility of lumbar paraspinal mapping in the diagnosis of lumbar spinal stenosis.

Yagci I, Gunduz OH, Ekinci G, Diracoglu D, Us O, Akyuz G: The utility of lumbar paraspinal mapping in the diagnosis of lumbar spinal stenosis. Objective:The aim of this prospective, blinded and controlled study is to evaluate the utility of lumbar paraspinal mapping in the diagnosis of lumbar spinal stenosis. Design:The subjects were assessed and allocated into three groups according to clinical and radiologic features with a standardized assessment protocol. These three groups were clinical and radiologic lumbar spinal stenosis, radiologic lumbar spinal stenosis, and the control group. The measurements of magnetic resonance imaging studies were performed by a blinded radiologist. An electromyographer who was masked to patients’ data performed all the nerve conduction tests, lower-limb needle electromyography, and lumbar paraspinal mapping. The relations of clinical, radiologic, and electrophysiologic findings were investigated. Results:Sixty-two patients were enrolled in the study. Two patients were eliminated because electrophysiologic studies showed polyneuropathy. There were 28, 16, and 16 patients in clinical and radiologic lumbar spinal stenosis, radiologic lumbar spinal stenosis, and control groups, respectively. In the clinical and radiologic lumbar spinal stenosis group, the findings of limb needle electromyography were inconsistent with 50% acute and 46.4% chronic radiculopathy. However, the paraspinal mapping showed that there were fibrillation potentials and positive sharp waves in at least two levels in 92.8% of the patients in clinical and radiologic lumbar spinal stenosis. The mean total paraspinal mapping score was 33.64 ± 21.17, which was significantly higher than the radiologic lumbar spinal stenosis and control groups. In the radiologic lumbar spinal stenosis group, the findings of paraspinal mapping were normal in 93.8% of the patients. Paraspinal mapping technique was found to be better correlated to the clinical findings than magnetic resonance imaging in asymptomatic patients. In the control group, 6 of 14 patients had high total paraspinal mapping scores (range, 0–9). Those patients with higher paraspinal mapping scores in the control group were mostly diagnosed with acute monoradiculopathy caused by disc herniation. Conclusions:Paraspinal mapping technique is a sensitive method in the diagnosis of lumbar spinal stenosis and reflects physiology of nerve roots better than the limb electromyography.

Relationship between maximal bite force and tooth wear in bruxist and non-bruxist individuals

OBJECTIVE (i) To compare individuals with self-reported bruxism and non-bruxist individuals in terms of maximal bite force (MBF) and temporomandibular joint (TMJ) primary assessment parameters and (ii) to examine the relationship between MBF and tooth wear in these subjects. MATERIALS AND METHODS Twenty-nine bruxist subjects and 29 healthy controls were enrolled. MBF measurements were carried out by the use of bite force recorder. Tooth wear indices, maximal mouth opening, maximal lateral excursions and maximal protrusions were measured for every subject. RESULTS MBF and tooth wear index scores were significantly higher in bruxists (p values <0.05) compared to non-bruxists. MBF and tooth wear index scores were found to be significantly correlated in the bruxist group (r=0.79, p=0.00). Less significant correlation was observed in the non-bruxist group (r=0.38, p=0.04). No differences in masticatory clinical examination parameters were identified between the groups. CONCLUSION This study is the first to show that MBF can increase in bruxist individuals and that the increase in MBF are correlated with tooth wear in bruxist subjects. Further studies regarding the possible role of MBF in bruxism are to be done.

Intra-Articular Hyaluronic Acid as Treatment in Elderly and Middle- Aged Patients with Knee Osteoarthritis

Introduction: Osteoarthritis is the most common age-related degenerative joint disease. It affects all the joints containing hyaline cartilage. Knee osteoarthritis is the most cumbersome in terms of prevalence and disability. The aim of this study to evaluate the efficacy of intra-articular hyaluronic acid in patients with knee osteoarthritis with regard to joint pain and function, as well as patient satisfaction, assessed at one month and at one year, and by age group. Methods: In this prospective randomised study, 172 patients who were diagnosed knee OA and who received three consecutive intra-articular injections of HA weekly were included. Patients 65 years of age or older were accepted as the “elderly group”, and those under 65 were accepted as the “middle-aged group”. Clinical evaluations of efficacy and safety were conducted at the beginning of the study, one month after the third injection, and one year after the third injection. Results: In the two groups, the intragroup analysis revealed significant improvements following injection when compared with preinjection values. According to the last followup controls (after 12 months) in the middle-aged group, VAS activity pain, VAS rest pain, WOMAC physical function, and WOMAC pain values were found to be statistically lower when compared with pre-injection values. In the elderly group, no statistically significant differences were found between pre-injection and after 12 months. Conclusion: We can conclude that intra-articular joint HA injections are effective in both young and old patients with OA with regard to pain and functional status over a short-term period. Further, HA injections in patients younger than 65 years can be planned for a one-year period.

Low back pain: results of an open clinical trial comparing the standard treatment alone to the combination of standard treatment and thiocolchicoside

Abstract For symptomatic relief of low back pain, non-steroidal antiinflammatory drugs (NSAIDs) and analgesics are often in used in combination with muscle relaxants. However adverse effects, especially sedation, limit the use of some muscle relaxants. Thiocolchicoside (TCC) is a non-sedating muscle relaxant that has been shown to be safe and effective as monotherapy in the treatment of this problem. The present study was carried out to determine if the combination of thiocolchicoside and standard treatment is more effective than standard treatment alone.Ninety-three Turkish centers recruited adults presenting with acute and subacute low back pain. Each physician included four patients. Patients were randomized to receive either a NSAID or an analgesic for 5 to 7 days (referred to as “standard treatment”) or standard treatment plus 8 mg TCC (Muscoril) twice daily for 5 to 7 days. On inclusion and again on day 7, low back pain was evaluated with a visual analogue scale (VAS) and disability was evaluated with the Roland-Morris disability questionnaire. Pain and disability were evaluated again on day 31.A total of 155 patients were randomized to receive standard treatment alone and 174 received standardtreatment and TCC. The vast majority (98.2%) of the patients received a NSAID as standard treatment. The mean VAS and disability questionnaire scores of the two groups were equivalent at inclusion. At day 7, patients in both groups were improved but patients receiving TCC had significantly less pain (p<0.003) and disability (p=0.0005) than patients on standard treatment alone; this was also true at day 31. (p<0.005 and p=0.0005, respectively). The addition of TCC to NSAID standard treatment resulted more effective for the symptomatic treatment of low back pain than the NSAID alone. In addition, the combination was well tolerated and produced no more adverse effects than the NSAID alone.
