Case A-10 Mr. McMasters
Since the removal of his tumor, Mr. McMasters has been going through quite a few developmental changes. He has experienced a loss of short term memory and attention span, as well as difficulty with multi-step commands and sequencing. He has also been having trouble telling his left from his right, and is also seeing a significant decrease in strength, sensation, and range of motion of his right upper extremity.
Mr. McMasters is a retired social-studies teacher, who enjoys several activities including hunting, fishing, gardening, playing cards, and more. These few tasks in particular, will require the use of his right arm, and it will be essential to restore as much function as possible to this extremity. At the age of 58, it will be very unlikely that Mr. McMasters will be able to restore much function because of the lack of plasticity in his brain. Where function can not be regained, it will be important for Mr. McMasters to be able to adapt to using his right arm within limitations, or in some cases using his left arm more predominately. For his occupation of hunting, Mr. McMasters will be required to load a gun, hold it steady, and pull the trigger. He will most likely need to be able to field dress his kill as well, which involves the use of a knife to skin and eviscerate the animal.
Because Mr. McMasters has full passive range of motion and good finger flexion, I would suggest that he remain shooting right-handed. He should practice target shooting using a table or bench to assist him in holding his arm up and stabilizing the gun. We would be able to use a toy gun in the clinic to practice adaptive positioning, gradually adding weight to the gun and eventually simulating a “kick” by jolting the gun while he was holding it.
I would also have him working on strengthening and steadying his grip and pulling a “trigger” using a “Digi-flex” isolated finger exerciser, gradually increasing the difficulty as Mr. McMaste
rs strength improves. We would work on stimulating his trigger finger in attempt to improve the sensation necessary for pulling the trigger on time and steadily.
If possible, and after improvements have been made in the clinic, I would take Mr. McMasters to a shooting range to practice the necessary adaptations that shooting would require with a working gun. This is where we would be able to work with professionals on the dynamics of loading a gun, and extra safety precautions we may need to take into account.
I would be sure to suggest to Mr. McMasters that he bring along a friend or relative when he goes hunting, someone who would be able to keep his attention focused on the task at hand and help him safely dress his kills. Another option would be to take the animals to a meat processor or a taxidermist to perform the task for him. Although Mr. McMasters has seen a significant loss in the function of his dominant hand and arm, I believe that with some assistance and adaptive equipment, he will be able to continue his occupation of hunting.
