Description: Segment 1 This film shows the effects of lead poisoning, specifically on the hands and arms. The film shows the wrists being in a fixed position, with the fingers pointing down. A doctor points out the atrophy of the muscles in the hands and fingers of the patient. A doctor performs a tricep reflex test by tapping the patient's elbow with a hammer, but the patient has a lack of reponse. Also a lack of response to the radial reflex test. Response to the same test is shown in a subject with no lead poisoning. Extension of the forearm and hands are compared in the patient and subject without poisoning. The doctor demonstrates that passive movement is unaffected, and moves the patient's hands up and down. A sensitivity test is also performed, with the doctor touching parts of the arm, and the patient indicating the parts touched. Next, reactions to electrical stimulation is shown. The patient's arm shows only a little movement in reaction to the test, and a healthy subject is also tested, showing a large reaction. A pathological case is also shown, and the patient again has very little reaction to the electrical stimulus. Time start: 00:00:00:00 Time end: 00:06:35:06 Length: 00:06:35:06
