To evaluate the long-term efficacy of non-surgical treatment methods for mild and moderate carpal tunnel syndrome, 120 patients with clinical symptoms and electrophysiologic evidence were included in a prospective, randomized and blinded trial: 60 patients were instructed to wear splints every night, 30 received injections of betamethasone 4 cm proximal to the carpal tunnel, and 30 received injections distal to the carpal tunnel. After approximately 1 year (mean, 11 months; range, 9-14), 108 patients were available for final evaluation. We assessed clinical symptom severity and performed detailed electrophysiologic examinations before and after treatment. Splinting provided symptomatic relief and improved sensory and motor nerve conduction velocities at the long-term follow-up when the splints were worn almost every night. Proximal and distal injections of steroids were ineffective on the basis of both clinical symptoms and electrophysiologic findings. Decompressive surgery and steroid injection are widely used forms of treatment for carpal tunnel syndrome (CTS) but there is no consensus on their effectiveness in comparison to each other. The authors evaluated the efficacy of surgery vs steroid injection in relieving symptoms in patients with CTS.
                The authors conducted a randomized, single blind, controlled trial. Fifty patients with electrophysiologically confirmed idiopathic CTS were randomized and assigned to open carpal tunnel release (25 patients) or to a single injection of steroid (25 patients). Patients were followed up at 6 and 20 weeks. The primary outcome was symptom relief in terms of the Global Symptom Score (GSS), which rates symptoms on a scale of 0 (no symptoms) to 50 (most severe). Nerve conduction studies and grip strength measurements were used as secondary outcome assessments.
                At 20 weeks after randomization, patients who underwent surgery had greater symptomatic improvement than those who were injected. The mean improvement in GSS after 20 weeks was 24.2 (SD 11.0) in the surgery group vs 8.7 (SD 13.0) in the injection group (p < 0.001); surgical decompression also resulted in greater improvement in median nerve distal motor latencies and sensory nerve conduction velocity. Mean grip strength in the surgical group was reduced by 1.7 kg (SD 5.1) compared with a gain of 2.4 kg (SD 5.5) in the injection group.
                Compared with steroid injection, open carpal tunnel release resulted in better symptomatic and neurophysiologic outcome but not grip strength in patients with idiopathic carpal tunnel syndrome over a 20-week period. To study the efficacy of splinting and oral steroids in the management of carpal tunnel syndrome (CTS).
                Prospective, randomized, open-label, clinical and electrophysiological study with 3-month follow-up.
                Forty patients with CTS were randomly divided into splint group (N-20), wearing splint in neutral position for 4 weeks; and steroid group (N-20), who received oral prednisolone 20 mg/day for 2 weeks followed by 10 mg/day for 2 weeks. Clinical and electrophysiological evaluations were done at baseline and at 1-month and 3-month follow-up. Independent 't' test and paired 't' test were used for statistical analysis.
                Primary outcome measure was the symptom severity score and functional status score. Secondary outcome measures were median nerve sensory and motor distal latency and conduction velocity.
                At the end of 3 months, statistically significant improvement was seen in symptom severity score and functional status score in both groups (P<0.001). Median nerve sensory distal latency and conduction velocity also improved significantly in both the groups at 3 months. Improvement in motor distal latency was significant (P=0.001) at 3 months in steroid group, while insignificant improvement (P=0.139) was observed in splint group. On comparing the clinical and electrophysiological improvement between the two groups, except for the functional status score, there was no significant difference at 3-month follow-up. Improvement in functional status score was significantly more in steroid group (P=0.03).
                There was significant improvement in both groups, clinically as well as electrophysiologically, at 3 months. On comparing the efficacy of the two treatment methods, except for the functional status score, there was no significant difference between the two groups. The objective of this study was to investigate the effectiveness of splinting, ultrasound (US), and low-level laser (LLL) in the management of carpal tunnel syndrome (CTS).
                CTS is the entrapment mononeuropathy most frequently seen in clinical practice, caused by compression of the median nerve at the wrist. Although several treatment modalities are routinely in use, there is no consensus about the best way to manage CTS.
                In our study, patients were randomly allocated to three groups that received the following treatment protocols: splinting only, splinting plus US, and splinting plus LLL therapy. Patients were assessed with the Boston Questionnaire, patient satisfaction inquiry, visual analogue scale for pain, and electroneuromyography.
                The study was completed with a total of 100 hands of 50 women patients with bilateral CTS at 3 mo after treatment. At the end of the follow-up period, each of the groups had improvements to varying degrees. It appeared that the combinations of US or LLL therapy with splinting were more effective than splinting alone in treating CTS. However, LLL therapy plus splinting was more advantageous than US therapy plus splinting, especially for the outcomes of lessening of symptom severity, pain alleviation, and increased patient satisfaction. The aim of this study was to investigate and compare the therapeutic effect of three different combinations in the conservative treatment of carpal tunnel syndrome (CTS) by means of clinical and electrophysiological studies. The combinations included tendon- and nerve-gliding exercises in combination with splinting, ultrasound treatment in combination with splinting and the combination of ultrasound, splinting, tendon- and nerve-gliding exercises. A total 28 female patients (56 wrists) with clinical and electrophysiologic evidence of bilateral CTS were studied. In all patient groups, the treatment combinations were significantly effective immediately and 8 weeks after the treatment. The results of the long-term patient satisfaction questionnaire revealed that symptomatic improvement is more prominent in the group treated with splinting, exercise and ultrasound therapy combination. Our results suggest that a combination of splinting, exercise and ultrasound therapy is a preferable and an efficacious conservative type of treatment in CTS. This study aimed to compare the efficacy of ultrasound treatment to local corticosteroid injection plus splinting in carpal tunnel syndrome (CTS). There is still limited knowledge on the efficacy of conservative treatment options for CTS.
                Fourty-nine hands of 34 patients with CTS were enrolled in this study. Patients were randomly assigned to the ultrasound treatment (group A) or local corticosteroid injection plus splinting (group B). The primary outcome measures included clinical parameters such as symptoms severity score, visual analogue scale (VAS) pain, functional status score, grip strength and two-point discrimination. The secondary outcome measures were the electrophysiological tests. The examinations were performed at baseline, and then at 4th and 8th weeks.
                At the end of the study, a statistically significant improvement was obtained in all clinical parameters in the group B: VAS pain, severity of symptoms, functional status, grip strength (p < 0.001 for each) and two-point discrimination (p < 0.016). Also the group A showed significant improvements in all clinical parameters (p < 0.001 for each), except for the grip strength. Additionally, significant improvements in the median nerve sensory conduction velocity and distal motor latency were also found in both groups at the end of the 8 week follow-up period. There was no significant difference between the groups in the primary and secondary outcome measures, except for the grip strength.
                Both ultrasound treatment and corticosteroid injection plus splinting were effective on the clinical symptoms and the electrophysiological findings of CTS. Thus, the ultrasound therapy may be an alternative treatment for CTS, particularly in patient who do not accept injection or splinting (Tab. 3, Fig. 2, Ref. 36). To compare the efficacy of local corticosteroid injection to a nonsteroidal antiinflammatory drug and splinting for the treatment of carpal tunnel syndrome.
                This study was a prospective, unblinded, randomized clinical trial with an 8-wk follow-up. Thirty-three hands of 23 patients were randomly treated with acemetacine and splinting (group A) or with corticosteroid injection (group B). Clinical (symptom severity scale, visual analog scale, Tinel and Phalen tests) and electromyographic evaluations were performed on initial visit and after 8 wk.
                Clinical and electromyographic parameters, which were similar at baseline, were improved in both groups after treatment. Improvement was also similar when both groups were compared at 8 wk.
                Both splinting combined with the use of a nonsteroidal antiinflammatory drug and steroid injection into the carpal tunnel resulted in significant improvement in carpal tunnel syndrome. Carpal tunnel syndrome (CTS) is the most common of the compression neuropathies. Several studies have demonstrated the efficacy of wrist splinting in relieving the symptoms of CTS; however, the chosen angle of immobilization has varied. Wick catheter measurements of carpal tunnel pressures suggest that the neural position has less pressure and, therefore, greater potential to provide relief from symptoms. This study is a prospectively gathered, blind trial comparing the symptom relief experienced by wearers of splints immobilized at 20 degrees extension and at neutral. The results indicate that the neutral angle provided superior symptom relief, and that the relief did not often improve between 2 weeks and 2 months of wear. Relief of symptoms was not related to the length of time that the patient had experienced of CTS symptoms. The results also indicate that the results of the electromyography/nerve conduction study (EMG/NCS) do not provide information about the subjects' likely response to splinting. A double-blinded placebo-controlled trial was performed to evaluate the use of steroid injections beneath the transverse carpal ligament in the treatment of carpal tunnel syndrome (CTS) refractory to nonsurgical therapy. Forty-three patients received 6 mg betamethasone and lidocaine and 38 patients received 1 ml saline placebo and lidocaine. The primary outcome measure was satisfaction with symptom relief. Thirty patients (70%) in the steroid-treated group were satisfied or highly satisfied compared with 13 (34%) of placebo-treated patients (P < 0.001). Patients receiving steroids also showed significant improvement in median nerve conduction parameters and scores on validated symptom/function questionnaires. Forty-six patients were treated with serial injections for recurrent CTS symptoms. After 18 months, 17 patients reported adequate symptom relief with steroid injection, and 18 patients with unsatisfactory symptom relief were referred for carpal tunnel release surgery. We conclude that although steroid injections are safe and effective for temporary relief of CTS, most patients will eventually require surgery for long-term control of their symptoms.
Surgical treatment of carpal tunnel syndrome relieves symptoms significantly better than splinting. Further research is needed to discover whether this conclusion applies to people with mild symptoms and whether surgical treatment is better than steroid injection.
