How Safe are Walkers?
(12/9/13)- Spending at least an hour a day walking was associated with a reduced likelihood of suffering a stroke among older men, according to a U.K. study in the journal Stroke. The likelihood of stroke declined by about one-third among men who walked eight to 14 hours each week, and approximately two-thirds in men who walked more than 22 hours.
(7/9/09)- The results of a study that was reported in a recent edition of the Journal of the American Geriatrics Society found that 87% of fall injuries involved walkers and 12% involved canes. About 47,000 older Americans are treated in emergency rooms each year from falls associated with walkers and canes.
Judy A. Stevens, an epidemiologist at the Centers for Disease Control and Prevention and the study's lead author went on to say: "It's important to make sure people use these devices safely."
Researchers examined emergency-room medical records at 66 hospitals from January 1, 2001 to December 31, 2006, focusing in on people 65 and older who had been using a walker or a cane at the time of the fall.
The study found that fractures, bruises and abrasions were the most common injuries associated with the falls. About one-third of the injuries were to the lower trunk, including the hips.
Sixty percent of fall injuries associated with walkers and canes occurred at home, while 16% of falls involving a walker occurred in a nursing home.
The researchers concluded with the thought about it being time to improve the design of walkers and canes so that they are safer for users of these devices.
(4/16/09)- It is estimated that the average person will walk the equivalent of three times around the earth in a lifetime. Can you imaginre the wear and tear this puts on the 26 bones, 33 joints and over 100 tendons, ligaments and muscles that make up the foot?
A survey for the American Podiatric Medical Association reported 53 percent of respondents had foot pain so severe that it hampered their daily function. On average, people develop pain in their 60s, but it can start as early as the 20s and 30s. Yet, except for women who get regular pedicures, most people don’t take much care of their feet.
(8/8/99)-Your co-editors have always practiced what we preach in connection with the healthful affects of walking. We have found it to be quite relaxing mentally as well as having physical benefits. We do not believe that you have to be a "speed" walker to derive benefits from walking. Do it at your own pace and you will derive benefits from having done it. The Journal of Nature recently reported on an experiment done at the University of Illinois on 124 sedentary men and women in the 60 to 75 age range.
The study's result indicated that an "invigorating" walk sharpened both memory and judgment in the experimental group. At the same time it was determined that anaerobic exercises (stretching and weight lifting) did not produce similar cognitive results.
The 124 sedentary men and women were randomly assigned either a walking or anaerobic regimen over a 6-month period of time. The walk took about 1 hour to complete. The study's lead author was Dr. Arthur Kramer, a cognitive neurologist. Tests were administered on the participant's ability to plan, establish schedules, make and remember choices, and rapidly reconsider them if circumstances warranted. According to neurologists the brain's frontal and prefrontal lobes control these brain functions. Dr. Kramer asserted that "These areas of the brain decline the earliest with aging". In "task switching" tests the walkers had about a 25% improvement in their results. The tests consisted of being shown alternating letters and numbers and being asked to quickly determine between vowels and consonants and between odd and even numbers.
The word "hemiplegia" indicates a stroke illness with emphasis on motor deficit involving loss of locomotion. Attention is then focused on this motor deficit, without reference to the examination of equilibrium. According to Mohr in Topics in Neurology, 1990 (pp. 1-11),"stability and intact equilibrium are essential for unassisted walking, even if there is residual weakness in one leg". Stephenson, writing in the journal called Physiotherapy, 1993;79:699-704, points out the importance of retraining the midline orientation rather than teaching the intact side to compensate for the paralyzed limbs. A number of researchers at the Shaare Zadek Medical Center in Jerusalem took up this idea and explored how early observation on equilibrium might provide a prognostic and diagnostic guide to the stroke patient's potential recovery of mobility.
They define equilibrium "as the ability of the body to maintain its center of gravity within its support base or to restore it to its support base if displaced from it". They felt that sitting equilibrium reflects the state of equilibrium reflexes "even before significant return of power to the leg allows assessment of standing and walking". They also knew that active rehabilitation is likely to be effective during a period of six months after onset of the stroke.
They state "Attempts to predict functional recovery from stroke can only be approximate, as they depend on physiopathological factors in the brain, the background pathology of the patient, and the emotional makeup. An approximate guide of prognosis can help, however, in planning treatment and future life-style. (Emphasis added by this author.)
"Improvement after a cerebral insult occurs because of two processes: 'intrinsic' or spontaneous neurological remission and 'extrinsic' or functional improvement that is dependent on motor learning and neuroplasticity. Since posture is fundamental to stability as well as movement, attention to midline orientation is one of the principles of rehabilitation from the earliest stages. Learning and reinforcing techniques are the instruments of rehabilitation, and, therefore, daily practice in posture should form part of the routine management of stroke patients…Attending physicians and nurses should familiarize themselves with some of these simple techniques of measurement and treatment of equilibrium, because the process of conditioning, if carried out intensively enough during the first few weeks, may reveal innate potential for recovery and make the management of stroke patients a more fulfilling experience for staff".
