La industria de la construcción, de las más significativas en el desarrollo económico del país, no ha tenido el desarrollo que se esperaba en Arequipa. Se sabe que un problema recurrente es el alto nivel de incertidumbre de la productividad de la mano de obra, por lo que conocer el nivel y causas de este es necesario para tomar las acciones correctivas necesarias. En el capítulo uno hablaremos sobre las generalidades del presente trabajo, estableciendo los antecedentes, objetivos e hipótesis. El capítulo dos expone el marco teórico que desglosa las definiciones generales de Productividad y LEAN Construction, necesarias para contextualizar la investigación, se desarrollan los factores que afectan la productividad y conceptos generales de mano de obra, además se explican las técnicas LEAN y las herramientas utilizadas en esta investigación (Carta Balance y Ratios de Productivid...

A 49-year old woman was evaluated for developing bilateral acute medial elbow pain, numbness, and tingling sensation in the fourth and fifth fingers after receiving radial extracorporeal shock wave therapy (rESWT) for bilateral medial epicondylitis. Neurologic examination revealed the presence of Tinel’s sign, paresthesia and impaired two-point discrimination testing over the ulnar side of the fourth and fifth fingers bilaterally. High-resolution ultrasonography demonstrated findings of nerve injury, such as hypoechogenicity and increased diameter of both ulnar nerves.  After conservative treatment, the patient improved her condition demonstrating an apparently acute compressive nerve injury as a result of the therapy. ESWT is used as a promising alternative for the treatment of various musculoskeletal disorders; however, there is limited evidence regarding its side effects, in pa...
