Friday, April 12, 2019 PTJ: Falls Are 'Critical Health Hazard' for Individuals With Upper Limb Loss Arm motion is critical to helping compensate for losing one's balance and avoiding a fall. For individuals with upper limb loss (ULL), the lower extremities take on the burden of reacting to avoid a fall, and the lack of upper arm movement may put them at greater risk for falls than older individuals, say authors of a new study in PTJ (Physical Therapy). This "critical health hazard," they write, requires falls screening and "targeted physical therapy to enhance postural control and minimize fall risk." Via an anonymous online survey, researchers asked 109 individuals with an average age of 43 with ULL about their body and health characteristics, upper and lower limb loss characteristics, physical activity level, fall history in the previous year and circumstances, and upper limb prosthesis use. Participants also completed the the Activities-specific Balance Confidence (ABC) Scale. Authors found: Falls are prevalent in this population, surpassing fall rates for older individuals and stroke survivors. Including individuals with ULL and those with upper and lower limb loss, 45.7% fell at least once in the past 12 months, while 28.6% reported 2 or more falls. Those numbers were slightly lower for respondents with only ULL, with 40.7% reporting 1 fall and 22.0% reporting 2 or more falls. The percentage of respondents experiencing a single fall is higher than for older individuals (33%) and community dwelling stroke survivors (~40%). Of all those who reported falls, 31.7% were injured in the most recent fall and 14.6% required medical attention. Most falls were due to slips, trips, and loss of balance. Of the reported falls, 30% occurred while walking outdoors, and 30% occurred while walking up or down stairs. Only 11% of falls occurred during physical exercise or playing sports. Most fell because they lost their balance (27%), tripped (25%), or slipped (18%). Balance confidence and self-perception play a role. Respondents were significantly more likely to fall if they had lower balance confidence and low perceived physical capabilities. They also were 6 times more likely to fall if they reported using an upper limb prosthesis. These results, especially the high rate of injuries, have "considerable clinical importance because it suggests the presence of a critical health hazard for individuals with ULL," authors write. "Balance confidence, use of upper limb prostheses, and perceived physical capabilities could be useful screening metrics." While further research is necessary on which interventions are best to address these fall risks, authors suggest that balance-targeted therapies, as well as interventions developed for older adults to better recover from trips, could also help individuals with ULL "refine their motor response to perturbations and enhance overall stability." "Monitoring these patients during rehabilitation would help create awareness of this health concern, and identify individuals at risk of falling in the community who could benefit from intervention," they write.
