A nationwide update on prevalence of falls, injurious falls, concerns about falling, and fall prevention in persons with multiple sclerosis.

OBJECTIVE: To estimate the current nationwide prevalence of falls, injurious falls, concerns about falling, and information on fall prevention among people with multiple sclerosis (PwMS). DESIGN: This is a cross-sectional national web-based survey that included 965 adult PwMS. Participants self-reported falls and injurious falls experienced in the past 6 months. Participants also provided information on their concerns about falling and information on fall prevention received. RESULTS: A total of 56% reported falling in the past 6 months. The prevalence of falls at the population level ranges between 53% and 59%. Most falls occur inside of participants' homes (68%). About 30% of fallers reported an injurious fall. Most respondents, 87% expressed being concerned about falling and 68% reported they had cut down on activities due to their concerns about falling. Among participants who received information about falling (64%), only 9% received a formal fall prevention course. CONCLUSION: Despite advances in falls research over the last decades, falling continues to be a highly prevalent problem for PwMS. About one-third of those falls result in injuries. Concerns about falling among fallers and non-fallers affect the performance of daily activities and independence. Few people receive a formal falls prevention education or training.

Examination of Risk Factors Associated With Falls and Injurious Falls in People With Multiple Sclerosis: An Updated Nationwide Study.

OBJECTIVE: To provide an update on risk factors associated with falls and injurious falls among people with multiple sclerosis (PwMS) in the United States. DESIGN: Nationwide cross-sectional web-based survey. SETTING: Community setting. PARTICIPANTS: Adult PwMS (n=965). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants completed self-report surveys of demographics, clinical data, concerns about falling, occurrence of falls, factors associated with falls, and injurious falls in the past 6 months. Participants also completed Patient-Reported Outcomes Measurement Information System (PROMIS) measures of depression, pain interference, and physical function, and the Fatigue Severity Scale. RESULTS: The most common self-reported factors associated with falls included personal factors such as poor balance (75%), muscle weakness (54%), and/or fatigue (35%), environmental factors such as general surface conditions (37%) and/or distraction (15%), and activities-related factors such as urgency to complete a task (35%) and/or multitasking (27%). Logistic regression analyses indicated that higher fatigue severity (OR=1.19, P<.01) and higher pain interference (OR=1.02, P<.01) were associated with higher odds of experiencing at least 1 fall. Any level of concern, even minimal concern about falling was also significantly associated with a higher odd of experiencing at least 1 fall (ORs range 2.78 - 3.95, all P<.01). Fair to very high concerns about falling compared with no concern about falling (ORs range=5.17 - 10.26, all P<.05) was significantly associated with higher odds of sustaining an injurious fall. CONCLUSIONS: Findings suggest falls prevention approaches in PwMS should be multifactorial and include personal, environmental, and activities-related factors. Particular attention on fatigue, pain, and concern about falling may be needed to reduce incidence of falls and injurious falls in this population.

Improved Self-Reported Comfort, Stability, and Limb Temperature Regulation with an Immediate Fit, Adjustable Transtibial Prosthesis.

OBJECTIVE: The purpose of this investigation was to assess participants' self-reported satisfaction with an adjustable, immediate fit transtibial prosthetic system as compared to their conventionally fabricated prosthetic device. DESIGN: A prospective study involving a two-week single-group pre-post intervention design. SETTING: Physical medicine and rehabilitation clinic of a university hospital. PARTICIPANTS: Adults (N=27) with transtibial limb loss. INTERVENTION: Participants were fit with the iFIT prosthetic system and instructed to wear it for a two-week evaluation period. MAIN OUTCOME MEASURE: A modified PEQ scale was completed on the participant's conventional prosthetic during the initial visit and the iFIT system after the two weeks. RESULTS: Twenty-seven persons with lower limb loss were enrolled. Three were lost to follow up leaving twenty-four subjects with completed data. Three subjects had recent amputations with no conventional device for comparison. The Modified PEQ scores were significantly higher for the iFIT prosthetic in comparison to their conventional device (29.18 [SD= 4.63] vs 23.82 [SD=6.38], p <0.01). Subjects were also found to perceive significantly better temperature control with the iFIT prosthetic system (4.19 [SD= 0.68] vs 2.97 [SD=1.02], p <0.001). Subjects did not report any skin breakdown, prosthetic issues, or falls. CONCLUSION: This immediate fit, adjustable transtibial prosthesis demonstrated significantly better patient satisfaction and temperature perception compared to conventional devices. These results are consistent with previous findings and further support the efficacy of an immediate fit adjustable transtibial prosthetic system. Longer term studies in the United States and internationally are underway to assess the durability and efficacy of this new prosthesis in different populations and settings.
