Tunnel Syndrome

Background: Carpal tunnel syndrome is the most common entrapment neuropathy of the median nerve at the wrist. In general population CTS is known to be a very common disease and the prevalence of CTS is estimated to be 2.7% as confirmed by clinical and electrophysiological findings. Typical symptoms of CTS are tingling, numbness and parasthesia in thumb, index, middle finger and radial half of ring finger which is often exaggerated at night. Previously research studies have been done on pain control, grip strength, wrist function. Very little research work has been done on effect of exercise on NCS of CTS patients. So the aim of the study is to find the short term (6weeks) effects of exercise on NCS of CTS patients. Methodology: Bilateral sensory and motor nerve conduction studies were carried out in 50 CTS patients before and after 6weeks of exercise. Exercise treatment was given to patients under the guidance of trained physiotherapist. Clinical examination was also done after 6 weeks. RMS machine from Chandigarh was used. Statistical analysis was done by INSTAT- 3.6 software. Result: DML, DML (diff.) DSL, DSL (diff.) showed significant decrease after 6 weeks of exercise in symptomatic (Rt.) hand, but no significant difference was found in SCV, CMAP, SNAP of median nerve. Whereas in Lt. hand only DML (diff.) between median and ulnar nerve showed significant change. There was also improvement in clinical signs and symptoms and pain scale. Conclusion: It was concluded that exercise treatment for 6 weeks under the proper guidance of trained physiotherapist showed significant improvements in clinical as well as electrophysiological parameters in symptomatic hands. So, exercise treatment can be suggested as choice of treatment for CTS patients.

The sensory recovery was monitored for up to 1 year after decompression of the median nerve in 69 patients with carpal tunnel syndrome. Special attention was paid to the rate of recovery, the importance of constant or intermittent numbness or paraesthesiae preoperatively and the influence of gender. Most patients with numbness/paraesthesiae and those with abnormal two-point discrimination recovered within 10 days. Perception of touch and vibration recovered within 3 weeks in most patients but those with abnormal nerve conduction/sensory amplitude recovered slowly during follow-up. After 1 year patients with intermittent preoperative symptoms were significantly more likely to achieve normal nerve conduction and perception of touch. Women were more likely to achieve normal nerve conduction and perception of touch. A comparison of recovery between matched men and women with identical preoperative status showed no significant difference. The results indicate the importance of early treatment of carpal tunnel syndrome.

Tunnel Syndrome

Recent literature has revealed a long discussion about the importance and necessity of nerve conduction studies in carpal tunnel syndrome management. The purpose of this study was to investigate the possibility of automatic detection, based on electrodiagnostic features, for the median nerve mononeuropathy and decision making about carpal tunnel syndrome. The study included 38 volunteers, examined prospectively. The purpose was to investigate the possibility of automatically detecting the median nerve mononeuropathy based on common electrodiagnostic criteria, used in everyday clinical practice, as well as new features selected based on physiology and mathematics. Machine learning techniques were used to combine the examined characteristics for a stable and accurate diagnosis. Automatic electrodiagnosis reached an accuracy of 95% compared to the standard neurophysiological diagnosis of the physicians with nerve conduction studies and 89% compared to the clinical diagnosis. The results show that the automatic detection of carpal tunnel syndrome is possible and can be employed in decision making, excluding human error. It is also shown that the novel features investigated can be used for the detection of the syndrome, complementary to the commonly used ones, increasing the accuracy of the method.

Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, which results from median nerve compression. A lot of nonsurgical modalities are available for the management of mild to moderate situations. Local Hyalase hydrodissection (HD) of the entrapped median nerve could offer a desirable sustained symptom alleviation. Objectives: To evaluate the clinical efficacy of Hyalase/saline solution carpal tunnel HD on pain, functional status, and nerve conduction in patients with CTS. Study Design: A randomized, double-blinded trial. Setting: Anesthesia, pain, and rheumatology clinics in a university hospital. Methods: Patients: 60 patients with CTS (> 6 months’ duration). Intervention: patients were allocated equally into either group 1 (HD with Hyalase + 10 mL saline solution injection), or group 2 (HD with 10 mL saline solution only). Measurements: assessment of pain using Visual Analog Scale (VAS), functional disability (FD) score, and nerve conduction studies before injection, and over 6 months after injection. Nerve conduction parameters before injection and postinjection by the end of 3 and 6 months were evaluated as well. Results: Statistically significant lower postinjection values of VAS (1 ± 1.8, 2 ± 1.1, 2 ± 1.2, 2 ± 1.1) in group 1 versus (2 ± 1.2, 3 ± 1.7, 4 ± 1.5, 5 ± 2.6) in group 2 by the end of the first week, and the first, third, and sixth months, and significantly lower FD scores (15.3 ± 1.2, 13 ± 1.3, 10.2 ± 1.3, 10.2 ± 1.3) in group 1 versus (17.5 ± 1.8, 16.6 ± 2.8, 19.4 ± 3.2, 21.2 ± 2.5) in group 2 during the same time intervals. Nerve conduction study parameters have shown significantly higher velocity and lower latency in the Hyalase group than in the saline solution group by the 3 and 6 month follow-up. Limitation: We suggest a longer period could be reasonable. Conclusions: Carpal tunnel HD with Hyalase with saline solution is considered as an efficient technique offering a rapid onset of pain relief and functional improvements, and better median nerve conduction in patients with CTS over 6 months follow-up duration.

BACKGROUND: Carpal tunnel syndrome (CTS) is the most entrapment syndrome in general and is the most frequent peripheral nervous system involvement in systemic sclerosis (SSc). Local injection of steroid hydrodissection or ozone-oxygen showed favourable outcome in CTS in general. OBJECTIVES: To compare the clinical efficacy of ozone versus methylprednisolone intracarpal injection upon pain, functional status, and nerve conduction in patients with CTS due to SSc. STUDY DESIGN: A randomized single-blinded trial. SETTING: Anesthesia, pain, and rheumatology clinics in a university hospital. METHODS: Fifty CTS patients with > 3 months duration of SSc were equally randomized into either group O (injection of ozone/oxygen 25 mu-g/mL in 20 mL) or group M (methylprednisolone acetate 40mg, and 40 mg lidocaine in 20 mL). Visual analog scale (VAS) was measured pre-injection, then re-evaluated post-injection at 4 time points (1 week, 1 month, 3 months , and 6 months); Cochin Hand Function Scale (CHFS); and a median nerve electrophysiologic study was done before injection, then by the end of 3 months and 6 months. RESULTS: VAS was significantly lower in group M after 1 week (P = 0.01). Group O showed significantly lower VAS after 3 and 6 month (P < 0.001). Additionally, there was a significant decrease in the VAS during the whole study period within each group, in comparison to its baseline value. CHFS was significantly lower in the ozone group after 6 months (P < 0.001). The sixth month’s sensory conduction was significantly higher in group O (P = 0.002). The motor distal latency was significantly lower in the ozone group after 3 and 6 months (P < 0.001). LIMITATIONS: Follow-up period could be furtherly extended. CONCLUSION: Both intracarpal ozone or methylprednisolone afford favorable effects upon CTS in patients with SSc. However, ozone alleviates pain much more, enhances the hand functional status, and improves median nerve conduction in study with over six months duration.

Background Choosing cutoff values for nerve conduction studies (NCS) and ultrasound cross-sectional area (CSA) in the diagnosis of carpal tunnel syndrome (CTS) is critical in determining the diagnostic accuracy of the tests. The goals of this study were to: (1) determine the sensitivity and specificity of various electrodiagnostic and ultrasound threshold values for diagnosis of CTS; and (2) determine the number of hands that underwent NCS and ultrasound that were within 10% of threshold values. Methods A total of 309 hands of 235 patients were included in this study. Diagnosis of median neuropathy was made based on NCS by the independent physician performing the NCS. Criteria analyzed included distal motor latency of 4.4+ ms, distal sensory latency of 3.6+ ms, difference in median-ulnar mixed nerve palmar latency of 0.4+ ms, and CSA of the median nerve of 10+ mm2. Results Median neuropathy was diagnosed in 235 hands, whereas 74 hands were found not to have median neuropathy. Overall, 141 hands (46%) had at least 1 of the 3 electrodiagnostic variables within 10% of the diagnostic cutoff values, and 137 hands (44%) had a median nerve CSA within 10% of 10 mm2. By performing ultrasound in addition to NCS for each patient, an additional 65 hands (21%) had a definitive diagnosis on at least 1 of the 2 diagnostic modalities. Conclusions Ultrasound and NCS yielded a similar number of patients within 10% of their diagnostic threshold values. When used together, the number of patients with a nonborderline diagnosis on at least 1 diagnostic modality was increased substantially.
