P.O. Box 12345,City, State ,RE: EXAMINEE : Abc,CLAIM NUMBER : 12345-67890,DATE OF INJURY : April 20, 2003,DATE OF EXAMINATION : August 26, 2003,EXAMINING PHYSICIANS : Y Z, DC,Prior to the beginning of the examination, it is explained to the examinee that this examination is intended for evaluative purposes only, and that it is not intended to constitute a general medical examination. It is explained to the examinee that the traditional doctor-patient relationship does not apply to this examination, and that a written report will be provided to the agency requesting this examination. It has also been emphasized to the examinee that he should not attempt any physical activity beyond his tolerance, in order to avoid injury.,CHIEF COMPLAINTS: , Improved focal lower back pain.,HISTORY: , Abc is a 26-year-old man who immigrated to this country approximately six years ago. He speaks "un poquito" English and an interpreter is provided. He has worked for the last four years at Floragon Forest Products, where he normally functions as a "stacker." He indicates that another worker was on vacation, and because of this he was put on another job in which he separated logs using a picaroon. He was doing this on April 20, 2003, and was pulling on the picaroon when it gave way, and he fell backwards landing on a metal step, which was approximately 1 foot off of the ground. He demonstrates that he came down square on the step and did not fall backwards or hyperextend over it. He did not hit his upper back or neck or shoulders, and only sat down on the step as described. He had "a little" pain in his back at that time, but was able to get up and continue working. He completed his shift that day and returned to work the following day. He had the next two days off. He says that his symptoms persisted and increased, and on April 25, 2003, he went to the First Choice Physicians Chiropractic and Rehab Clinic, where he came under the care of Dr. Abcd, DC. The file contains an entrance form completed by Mr. Abc which indicates at the bottom under "previous occurrence of the same pain" a notation of "Yes, but it was not really the same, it was just a little and tolerable." There is an additional note on the side which states "no pain prior to this injury or on that day, occasional (but low back)." Saw this notation, he says today that he did not state this and that the form was done by "Edna" at Dr. Abcd's office.,Mr. Abc was initially treated three times a week and states that this has now been reduced to twice per week. He does not know how long the chiropractic treatment is to continue. Initially, he has been seen by Dr. Xyz on three occasions, the last being on August 15, 2003. Dr. Xyz has basically referred him back to Dr. Abcd for continued chiropractic management.,Mr. Abc has now returned to his normal job as a stacker and is able to do that with no significant increased pain. He does mention, however, that bending over, picking up anything particularly heavy is bothersome; however, he does not normally have to do that. He denies any new accident or injury that would be contributory either as a result of his work or outside activities or any motor vehicle accident. He does not participate physically in any sports or hobbies that would be a factor.,PRESENT COMPLAINTS: , Mr. Abc indicates at this time that he is overall better in that initially he had difficulty "moving." He grades his current overall level of pain as a 2 to 4 on a scale from 0 to 10, stating that the worst he had was at 6-7. He now has "good and bad days" which depends on his activity level noting that he is better over the weekend. He localizes his pain to the midline lumbosacral region. He states that initially he did experience some diffuse radiation into both lower extremities, but that this has now resolved. He occasionally will notice some tightness behind both knees, but again no radicular type of distribution. He denies any focal muscular weakness or sphincter disturbance. His quality of the pain at this time is a "tightness" which bothers him, again, primarily with bending at the waist and lifting. He is able to do his normal activities of life, including his work without any significant problem, noting again only increased pain with bending and lifting.,PAST HISTORY: , Mr. Abc denies any prior similar complaints or treatments. He denies any previous specific lower back injury. He has enjoyed essentially good lifetime health and denies any concurrent medical conditions or problems. He has seasonal allergies only with no known drug hypersensitivities. He has not been hospitalized overnight and has had no surgeries in his life. He currently takes OTC Advil and Tylenol for lower back pain, but no prescriptive medication. He does not smoke, drink, or use street drugs of any type. Review of systems and family history are generally noncontributory.,SOCIO-ECONOMIC HISTORY: , Mr. Abc, as indicated, was born and reared in Mexico and immigrated into this country six years ago.,Education: He has our equivalent of a high school education in Mexico with no additional formal education in United States.,Military History: He has no military experience in his life.,Work History: He currently is doing his normal work activities as a stacker without arbitrary restrictions or limitations. He is not receiving any Workers Compensation or other benefits at this time.,PHYSICAL EXAMINATION: , Abc presents as a cooperative and straightforward 26-year-old Hispanic male. He has a very thin body habitus with a reported height of 5 feet 7 inches and weight of 125 pounds. He is right hand dominant. He is noted to sit comfortably throughout the history taking process conversant with the interpreter and myself without observable guarding or postural conversation or motion. He did stand readily to full upright with equal weightbearing and exhibits normal spinal posture with double hips and shoulders. Lumbar lordosis is normal. He ambulates without a limp or lift, and is able to walk on heels and toes and perform a full squat and rise and hop without difficulty with some expression of increased lower back pain. Waddell's testing is negative on compression and traction with some slight increased lower back pain on passive rotation.,Kemp's maneuver of posterolateral bending has some increased localized lumbosacral pain, but no radiation distally into the buttocks or lower extremities.,Active lumbar ranges of motion with double inclinometer are:,Flexion 70 degrees.,Extension 20 degrees.,Side bending symmetric at 28 degrees.,He complains of lower back pain at the extremes of flexion only. Motion palpation reveals full mobility without any detectable intrasegmental fixation with normal symmetry and alignment.,Tendon reflexes are 2+ and symmetric at the knees and ankles without sensory loss to pinprick. Babinski's are neutral, and there is no clonus.,Manual muscle testing reveals 5/5 strength at the hips, knees, and ankles without give-way or complaint.,Supine passive straight leg raising is limited by hamstring tightness to 66 degrees bilaterally, but causes no expression of lower back pain or radiation. Cross leg with rotation hip joint motion is full on either side without reported hip or back pain. Hip flexion is symmetric at 130 degrees, again without complaint. Leg lengths appeared visually symmetric. Mid calf girth is 11-1/2 inches bilaterally. Five inches above the knees measured 13 inches right and left. The seated SLR is done to 90 degrees, and he brings his fingertips 2 inches from his toes, showing good flexibility at the waist despite the hamstring tightness noted in the supine straight leg raising test.,In the prone position, he has good gluteal strength on either side with Yeoman's test causing some increased lumbosacral pain but no focal sacroiliac involvement. No sacroiliac fixation is identified. Hibbs test is negative on either side.,On palpation, he reports midline tenderness at L5-S1 without additional areas of tenderness noted even to very firm palpatory pressure in the entirety of the lumbar spine over the pelvis. He indicates no focal or sacroiliac, sciatic notch, or trochanteric tenderness on either side. No definitive muscular spasm is noted in the lumbar paraspinal musculature.,Mr. Abc tolerated the examination process without apparent or expressed ill effect. ,IMAGING STUDIES:,  AP and lateral lumbar/pelvic views dated May 15, 2003 are reviewed. The films are negative for recent fracture or pathology. There appears to be a transitional lumbosacral area with a spatulated transverse process of L1 and slight narrowing of the lumbosacral disc space. No additional abnormalities are identified. The hip and sacroiliac articulations appear well preserved. Disc spacing in the rest of the lumbar spine appears normal, and no significant degenerative changes are identified. Soft tissue appeared normal without paraspinal mass or abnormality.,DIAGNOSIS: , Lumbosacral contusion/strain relative to the April 20, 2003 industrial accident - objectively resolved.,SUMMARY: , Discussion and recommendations in response to questions posed in your August 15, 2003 letter:,1. What is your diagnosis of the worker's condition as a result of the injury? Please provide objective medical findings that support your diagnosis. Please indicate if the objective findings are reproducible, measurable, or observable, and how.,The diagnosis of the workers condition secondary to the described April 20, 2003 fall is by history a lumbosacral contusion/strain. This impression is primarily made based on his history noting that at this time, he has no abnormal objective findings.,2. In your opinion, is the work injury a contributing cause of the diagnosis? If so, is the work injury the material contributing cause of the diagnosis? Please provide an explanation for your opinion.,It would appear that the work injury was the major contributing cause of the diagnosis.,3. Are there any off work factors that may have caused or contributed to the worker's current complaints or condition? (Such as idiopathic causes, predisposition, congenital abnormalities, off work injuries, etc.).nan
