Electrophysiological Grading of Carpal Tunnel Syndrome
ORIGINAL ARTICLE Electrophysiological Grading of Carpal Tunnel Syndrome MUHAMMAD WAZIR ALI KHAN ABSTRACT Background: Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy caused by a conduction block of distal median nerve at wrist. Women are affected more commonly than men. Clinical signs are quite helpful in diagnosis but electrophysiological tests yield accurate diagnosis and severity grading along with follow-up and management. Aim: To utilize nerve conduction studies (NCS) to diagnose carpal tunnel syndrome and further classify its severity according to the AAEM criteria. Methods: This descriptive study was conducted at the Department of Neurology, Sh. Zayed Medical College/Hospital, Rahim Yar Khan from June 2013 to Dec 2014. Overall, 90 patients and 180 hands were evaluated through nerve conduction studies. Patients with clinically high suspicion of CTS were included for NCS. Clinical grading was done using the AAEM criteria for CTS. Other variables like duration of symptoms, handedness, bilateral disease and gender were noted. Mean and median were calculated for age of the patients. Results: Ninety patients and 126 hands were identified with carpal tunnel syndrome. Most patients (80%) were females with age range from 19 to 75 years. More than one third had bilateral disease. Dominant hand was involved in majority of the patients. Most patients had (42.8%) severe CTS as per AAEM criteria. Also duration of symptoms directly correlated with severity of disease. Conclusion: Nerve conduction study is a valuable tool in accurate diagnosis and grading of carpal tunnel syndrome. Keywords: Phalen sign, Tinel Sign, electrophysiology, median nerve INTRODUCTION 4,5,6 electrophysiological findings, are quite valuable . -
Polyurethane Concrete Leveling
POLYURETHANE CONCRETE LEVELING EARTH SHORING GROUND IMPROVEMENT DEEP FOUNDATIONS VIBRATORY STONE COLUMNS MICROPILES GROUTING helitechccd.com | 800-246-9721 COMMERCIAL CONCRETE LEVELING SOLUTION Helitech® Civil Construction Division utilizes a state-of-the art technology to raise and level your existing concrete. Instead of breaking up, removing, and repouring the entire concrete slab, Helitech® CCD inserts a special Polyurethane combination below the surface to “lift” the slab back to its original height. STEP 1 STEP 2 STEP 3 FINISHED PROCESS After installing port holes in the existing concrete (1), Helitech® CCD injects a Polyurethane material into ports using a special hydraulic system (2). The Polyurethane material expands to raise the surface of the slab to the desired height. The core holes are then filled with Portland cement (3) and repaired to produce a smooth, level surface. BENEFITS POLYURETHANE LEVELING By utilizing the Polyurethane Concrete Leveling method, Helitech® CCD has the ability to 2-5 lbs per Cubic Foot raise the given slab without adding the extra weight of the concrete to an already settling soil. Compared to Traditional Mudjacking which adds an additional 100 pounds per VS cubic foot, the Polyurethane Material is only 2-5 pounds per cubic foot depending on TRADITIONAL MUDJACKING the density being used. Polyurethane Concrete Leveling from Helitech® CCD is a green 100 lbs per Cubic Foot solution as the poly foam used is made from recycled material. USES Common applications include: roadways, undersealing, parking lots, factory and warehouse floors, interior commerical building slabs, airport runways, spillways, bridge approaches, and more.

Unsealed Road Grading Your Questions Answered
Unsealed Road Grading Your Questions Answered What is maintenance grading? Council grades unsealed roads to reshape and re-compact the road, to reduce lumps and bumps and ensure that the road will shed water away from the centre after rain. A grading maintenance schedule is adhered to every 6 or 12 months, depending upon the road condition, the amount of use and the effects of wet weather. What is gravel re-sheeting? Gravel re-sheeting is when new gravel is added to the road. This is due to the severe deterioration of the road that can compromise the safety of road users. The gravel is generally laid in loose layers and then trimmed and compacted using a grader, water cart and roller so that the new road generally has a depth of about 150mm. Why does my road lose gravel? Gravel wears away over time due to the combination of the environment (wetness and dryness), the type and volume of traffic and excessive traffic speed. Softer gravel rock will wear away faster than harder gravel rock. Unsealed roads are made up of a mixture of gravel of differing sizes, clay and soils. This mixture affects the strength of the pavement and how long it will last. The rock gives the pavement strength and the clay and other soils binds the gravel together. Where possible, the grader drivers will recover as much of the loose gravel as they can during the grading of a road and turn it from the edge back into the centre of the road. Why is does my road appear to be shrinking? As the road wears down over time the edges of the road pavement will wear and the width can become less. -
