Functional clinical motor performance tests to assess potential fall risks in patients with haemophilia: A case-control study.

INTRODUCTION: Patients with haemophilia (PwH) are at increased risk of falls due to haemophilic arthropathy. Yet, studies on clinical tests associated with the risk of falling are scarce in PwH. AIMS: (1) To evaluate the feasibility of different clinical motor performance tests associated with the risk of falling in PwH; (2) to evaluate PwH's performance of these tests compared to a control group; (3) to identify possible influencing factors that affect performance. METHODS: Twenty-nine severe and moderate PwH (57.0 years, IQR: 48.0-61.5) and 29 healthy age- and BMI-matched control participants (CG) performed 13 different clinical tests (SPPB, timed up and go, push and release, functional reach, single-leg stance, knee and grip strength). Haemophilia joint health score (HJHS), kinesiophobia (TSK-11), subjective physical performance (HEP-Test-Q), falls efficiency (FES-I) and falls were assessed. RESULTS: No adverse events occurred. PwH showed impaired performance in all clinical tests, a lower falls efficiency and a higher HJHS than CG. PwH with higher HJHS, lower HEP-Test-Q and higher TSK-11 scores showed higher deficits. Largest discrepancies were observed in the single-leg stance with eyes open and knee extensor strength, where orthopaedically majorly affected PwH showed worse performance compared to minorly affected PwH and the CG, respectively. The prevalence of ≥1 fall in the last year was 27.6% (PwH) and 10.3% (CG). CONCLUSION: These clinical tests are feasible in PwH. Impaired joint status, a high kinesiophobia and low physical performance impair performance. These tests can be used by clinicians for gaining specific information on functional motor abilities of patients.

Fall-risk-increasing drugs in older patients: the role of guidelines and GP-centred health care in Germany.

BACKGROUND: fall-risk-increasing drugs (FRIDs) are a ubiquitous issue, especially for older patients. As part of a German guideline for pharmacotherapy, from 2019, a new quality indicator for this patient group was developed to measure the percentage of patients receiving FRIDs. METHODS: patients, aged at least 65 years in 2020, insured by the Allgemeine OrtsKrankenkasse statutory health insurance (Allgemeine Ortskrankenkasse, Baden-Wuerttemberg, Germany) with a particular general practitioner (GP) were observed from 1 January to 31 December 2020 cross-sectionally. The intervention group received GP-centred health care. Within GP-centred health care, GPs have the role of gatekeepers for patients within the health system and are-in contrast to regular care GPs in addition to other commitments-obliged to regularly attend training sessions on appropriate pharmacotherapy. The control group received regular GP care. For both groups, we measured the percentage of patients receiving FRIDs as well as the occurrence of (fall-related) fractures as the main outcomes. To test our hypotheses, we performed multivariable regression modelling. RESULTS: a total of 634,317 patients were eligible for analysis. Within the intervention group (n = 422,364), we could observe a significantly reduced odds ratio (OR) for obtaining a FRID (OR = 0.842, confidence interval [CI]: [0.826, 0.859], P < 0.0001) in comparison to the control group (n = 211,953). Moreover, we could observe a significantly reduced chance for (fall-related) fractures in the intervention group (OR: 0.932, CI: [0.889, 0.975], P = 0.0071). CONCLUSIONS: the findings point in the direction that the health care providers' awareness of the potential danger of FRIDs for older patients is higher in the GP-centred care group.

Evaluation of the predictive validity of the Hessisch Oldendorf Risk of Falling Scale (HOSS).

OBJECTIVE: This study aims to further validate the Hessisch Oldendorf Risk of Falling Scale (HOSS) for neurological rehabilitation patients. DESIGN: The overall scale performance and fall rate was calculated in a retrospective data analysis. SETTING: The study was performed in a subacute care facility during inpatient neurological rehabilitation. SUBJECTS: The study population (n = 512) included neurological and neurosurgical patients with heterogeneous levels of disability. MAIN MEASURES: The HOSS total score and the suspected risk of falling were compared with the number of falls. Characteristics of fallers and non-fallers were compared using non-parametric group comparisons. Overall scale performance was assessed by calculating the area under the receiver operating characteristic curve of the HOSS as well as by calculating the sensitivity and specificity. RESULTS: A total of 82 (16%) patients experienced at least one fall. Fallers were characterized by an older age, a longer length of stay, a more severe impairment in the activities of daily living upon admission, a hemiparesis, an orientation disorder, a need of a walking aid device and an urinary incontinence. The number of falls was associated with the HOSS total score. Sixty-four fallers and two hundred seventy-four non-fallers were correctly categorized leading to a sensitivity of 78.0% and a specificity of 63.7%. The area under the receiver operating characteristic curve of the HOSS was 0.778 ± 0.25 (CI = 0.729-0.828, P < 0.001). CONCLUSION: The scale performance of the HOSS showed a good sensitivity and an adequate specificity to identify neurological patients who are at high risk of falling during inpatient rehabilitation.

Postural Control When Using an Industrial Lower Limb Exoskeleton: Impact of Reaching for a Working Tool and External Perturbation.

OBJECTIVE: To investigate postural control related to a lower limb exoskeleton (Chairless Chair) when (a) reaching for a working tool, and (b) an external perturbation occurs. BACKGROUND: Lower limb exoskeletons aiming to reduce physical load associated with prolonged standing may impair workers' postural control and increase the risk of falling. METHOD: Forty-five males were reaching for an object (3-kg dumbbell) at the lateral end of their reaching area without the exoskeleton in upright standing (STAND) and with the exoskeleton at a high (EXOHIGH.SEAT) and low sitting position (EXOLOW.SEAT). The task was performed with the object placed in three different angles (120°, 150°, and 180°) in the transversal plane. The minimum absolute static postural stability (SSABS.MIN) as the shortest distance (mm) of the center of pressure to the base of support border was measured (zero indicates risk of falling). Additionally, eight subjects were standing without the exoskeleton or sitting on it (EXOHIGH.SEAT and EXOLOW.SEAT) while being pulled backward. The tilting moment when subjects lost their balance was assessed. RESULTS: SSABS.MIN was lower when using the exoskeleton (p < .05) but still about 17 mm. The location of the object to be reached had no influence. Tilting moments of less than 30 nm were sufficient to let people fall backward when sitting on the exoskeleton (50 nm for STAND). CONCLUSION: Impairments in postural control by the exoskeleton may not be relevant when reaching laterally for objects up to 3 kg. When an external perturbation occurs, the risk of falling may be much higher; irrespective of factors like uneven or slippery flooring. APPLICATION: The risk of falling using the exoskeleton seems to be low when reaching laterally for an object of up to 3 kg. In situations where, for example, a collision with coworkers is likely, this exoskeleton is not recommended.

[Select and combine tools to assess the risk of an elderly person falling]. / Choisir et savoir combiner les outils d'évaluation du risque de chute d'une personne âgée.

Falls are a major problem in the elderly population. It is important to be able to effectively estimate the risk in order to implement appropriate actions. The large number of existing tools and the sometimes divergent or contradictory data make clinical assessment of this risk difficult. A review of the literature helps to determine the most relevant methods.

Association between everyday walking activity, objective and perceived risk of falling in older adults.

BACKGROUND: older persons can be grouped according to their objective risk of falling (ORF) and perceived risk of falling (PRF) into 'vigorous' (low ORF/PRF), 'anxious' (low ORF/high PRF), 'stoic' (high ORF/low PRF) and 'aware' (high ORF/PRF). Sensor-assessed daily walking activity of these four groups has not been investigated, yet. OBJECTIVE: we examined everyday walking activity in those four groups and its association with ORF and PRF. DESIGN: cross-sectional. SETTING: community. SUBJECTS: N = 294 participants aged 70 years and older. METHODS: ORF was determined based on multiple independent risk factors; PRF was determined based on the Short Falls Efficacy Scale-International. Subjects were allocated to the four groups accordingly. Linear regression was used to quantify the associations of these groups with the mean number of accelerometer-assessed steps per day over 1 week as the dependent variable. 'Vigorous' was used as the reference group. RESULTS: average number of steps per day in the four groups were 6,339 ('vigorous'), 5,781 ('anxious'), 4,555 ('stoic') and 4,528 ('aware'). Compared with the 'vigorous', 'stoic' (-1,482; confidence interval (CI): -2,473; -491) and 'aware' (-1,481; CI: -2,504; -458) participants took significantly less steps, but not the 'anxious' (-580 steps; CI: -1,440; 280). CONCLUSION: we have integrated a digital mobility outcome into a fall risk categorisation based on ORF and PRF. Steps per day in this sample of community-dwelling older persons were in accordance with their ORF rather than their PRF. Whether this grouping approach can be used for the specification of participants' needs when taking part in programmes to prevent falls and simultaneously promote physical activity remains to be answered in intervention studies.

Heart rate variability and falls in Huntington's disease.

PURPOSE: Persons with Huntington's disease (HD) have a high incidence of falls. Autonomic nervous system dysfunction has been reported even in early stages of this disease. To date, there has been no analysis of the relationship between heart rate variability (HRV) and falls in this patient population. The aim of the study reported here was to evaluate the relationship between HRV and falls in persons with HD. METHODS: Huntington's disease patients enrolled in a prospective study on fear of falling and falls were assessed using short-term HRV analyses and blood pressure measures in both the resting and standing states. Time-frequency domains and nonlinear parameters were calculated. Data on falls, the risk of falling (RoF) and disease-specific scales were collected at baseline and at the end of the 6-month follow-up. RESULTS: Of the 24 HD patients who were invited to participate in the study, 20 completed the baseline analysis and 18 completed the 6-month follow-up. At baseline, seven (35%) HD patients reported at least one fall (single fallers) and 13 (65%) reported ≥ 2 falls (recurrent fallers) in the previous 12 months. At baseline, recurrent fallers had lower RMSSD (root mean square of successive RR interval differences) in the resting state (RMSSD-resting), higher LF/HF (low/high frequency) ratio in both states and higher DFA-α1 parameter (detrended fluctuation analyses over the short term) in both states. This association was similar at the 6-month follow-up for recurrent fallers, who showed lower RMSSD-resting and higher LF/HF ratio in the standing state (LF/HF-standing) than single fallers. Significant correlations were found between the number of falls, RMSSD-resting and LF/HF-standing. No differences were found between recurrent and single fallers for any blood pressure measures. CONCLUSIONS: The observed HRV pattern is consistent with a higher sympathetic prevalence associated with a higher RoF. Reduced parasympathetic HRV values in this patient population predict being a recurrent faller at 6 months of follow-up, independently of orthostatic phenomena.

A Wrist-Worn Sensor-Derived Frailty Index Based on an Upper-Extremity Functional Test in Predicting Functional Mobility in Older Adults.

INTRODUCTION: Preoperative frailty is an independent risk factor for postoperative complications across surgical specialties. Functional mobility such as gait, timed up and go (TUG), and 5 times sit-to-stand (5-STS) are popular preoperative frailty measurements but are not suitable for patients with severe mobility impairment. A wrist-worn sensor-derived frailty index based on an upper-extremity functional test (20-s repetitive elbow flexion-extension task; UEFI) was developed previously; however, its association with functional mobility remained unexplored. We aimed to investigate the predictive power of the UEFI in predicting functional mobility. METHODS: We examined correlation between the UEFI and gait speed, TUG duration, and 5-STS duration in 100 older adults (≥ 65 years) using multivariate regression analysis. The UEFI was calculated using slowness, weakness, exhaustion, and flexibility of the sensor-based 20-s repetitive elbow flexion-extension task. RESULTS: The UEFI was a significant predictor for gait speed and TUG duration and 5-STS duration (all R ≥ 0.60; all p < 0.001) with the variance (adjusted R2) of 35-37% for the dependent variables. The multivariate regression analysis revealed significant associations between the UEFI and gait speed (ß = -0.84; 95% confidence interval [95% CI] = [-1.19, -0.50]; p < 0.001) and TUG duration (ß = 16.2; 95% CI = [9.59, 22.8]; p < 0.001) and 5-STS duration (ß = 33.3; 95% CI = [23.6, 43.2]; p < 0.001), found after accounting for confounding variables (e.g., age and fear of falling scale). CONCLUSIONS: Our findings suggest that the UEFI can be performed with a wrist-worn sensor and has been validated with other established measures of preoperative frailty. The UEFI can be applied in a wide variety of patients, regardless of mobility limitations, in an outpatient setting.

A simple instrument to assess the risk of falling in postpartum women: the SLOPE scale (riSk of faLling in pOstPartum womEn).

The purpose of this study was to introduce a novel instrument aimed at stratifying the risk of falling in postpartum patients. The research was a survey of a sample of 460 midwives working at different hospitals, mainly in Northern Italy, except for a hospital in Rome (Italy). The survey, consisting of 70 items, was conducted among midwives and asked them to express their opinion regarding the increased risk of falling in puerperal women on a Likert scale according to the characteristics listed in the questionnaire. Items were derived from the synthesis of scales available in the literature from settings other than the postpartum period, and interviews were conducted with midwives with great experience in this area. A shortened version was obtained using principal component analysis. A 30-item final scale was obtained, the SLOPE (riSk of faLling in pOst-Partum womEn), ranging from 0 to 100. The scale allows stratification of postpartum women at low (0-10), intermediate (10-20) and high risk (>20) of falling. The development of the SLOPE scale is the first step towards more rational evidence-based management of the risk of falling in postpartum women in current clinical practice.Impact statementWhat is already known on this subject? Falls occurring in the postnatal period are not limited to women because infants are often involved in this adverse event, with several significant consequences. There is a lack of information on this issue due to the absence of both registries and scales for the prevention of falls.What do the results of this study add? The main result of this study is the development of a novel scale to assess the falling risk in postpartum women.What are the implications of these findings for clinical practice and/or further research? The development of this novel scale, even if based on midwives' experience and not on patients' data, is a first step towards a more rational evidence-based management of the risk of falling in postpartum women.

Factors associated with screening positive for high falls risk in fragility fracture patients: a cross-sectional study.

BACKGROUND: We sought to report the prevalence of fragility fracture patients who were screened at high falls risk using a large provincial database, and to determine the characteristics associated with being screened at high falls risk. METHODS: The study population included fragility fracture patients 50+ years of age who were screened at 35 hospital fracture clinics in Ontario over a 3.5 year period. The outcome was based on two screening questions measuring the risk of falling, both adapted from the STEADI (Stopping Elderly Accidents, Deaths & Injuries) tool. Multivariable associations of sociodemographic, fracture-related, and health-related characteristics were evaluated using logistic regression. RESULTS: Of the sample, 9735 (44.5%) patients were classified as being at high falls risk, and 12,089 (55.3%) were not. In the multivariable logistic regression, being 80+ years of age (vs. 50-64 years of age), non-community dwelling (vs. living with spouse, family member, roommate), having a mental/physical impairment (vs. none), and taking multiple medications, were all strongly associated with being screened at high falls risk. CONCLUSIONS: Living in a non-community dwelling and taking 4+ medications were the variables most strongly associated with being screened at high falls risk. These are potentially modifiable characteristics that should be considered when assessing falls risk in fragility fracture patients, and particularly when designing interventions for preventing subsequent falls. Ongoing work to address the higher risk of falls in the fragility fracture population is warranted.

Gait Characteristics under Imposed Challenge Speed Conditions in Patients with Parkinson's Disease During Overground Walking.

Evaluating gait stability at slower or faster speeds and self-preferred speeds based on continuous steps may assist in determining the severity of motor symptoms in Parkinson's disease (PD) patients. This study aimed to investigate the gait ability at imposed speed conditions in PD patients during overground walking. Overall, 74 PD patients and 52 age-matched healthy controls were recruited. Levodopa was administered to patients in the PD group, and all participants completed imposed slower, preferred, and faster speed walking tests along a straight 15-m walkway wearing shoe-type inertial measurement units. Reliability of the slower and faster conditions between the estimated and measured speeds indicated excellent agreement for PD patients and controls. PD patients demonstrated higher gait asymmetry (GA) and coefficient of variance (CV) for stride length and stance phase than the controls at slower speeds and higher CVs for phases for single support, double support, and stance. CV of the double support phase could distinguish between PD patients and controls at faster speeds. The GA and CVs of stride length and phase-related variables were associated with motor symptoms in PD patients. Speed conditions should be considered during gait analysis. Gait variability could evaluate the severity of motor symptoms in PD patients.

Abdominal trunk muscle weakness and its association with chronic low back pain and risk of falling in older women.

BACKGROUND: Previous studies have indicated that trunk muscle strength decreases with chronic low back pain, and is associated with poor balance, poor functional performance, and falls in older adults. Strengthening exercises for chronic low back pain are considered the most effective intervention to improve functional outcomes. We developed an innovative exercise device for abdominal trunk muscles that also measures muscle strength. The correlation between muscle weakness, as measured by our device, the presence of chronic low back pain, and decreased physical ability associated with a risk of falling were evaluated in older women. METHODS: Thirty-eight elderly women, who could walk without support during daily activities and attended our outpatient clinic for treatment of chronic low back pain, knee or hip arthritis, or osteoporosis, were included in this study. Anthropometric measurements were performed. Grip power and one-leg standing time with eyes open were measured, and abdominal trunk muscle strength was measured using our device. History of falling in the previous 12 months was noted. Subjects with chronic low back pain (visual analog scale score ≥ 20 mm) for over 3 months were assigned to the low back pain group (n = 21). The remaining subjects formed the non-low back pain group (n = 17). RESULTS: Abdominal muscle strength of subjects in the low back pain group, and with history of falling, was significantly lower compared with that of subjects in the non-low back pain group, and in subjects without a history of falling, respectively. There was a moderate positive correlation between abdominal trunk muscle strength and one-leg standing time with eyes open. CONCLUSION: We measured abdominal muscle strength in older women with chronic low back pain using our device, and it was significantly lower than that of those without chronic low back pain. Muscle weakness was associated with a history and risk of falling.

[Initiation of pharmacotherapy as a risk factor for older patients.]

The article presents the literature and original data on the problems of falls in elderly patients. The connection of the fact of falling with initiation of therapy by a number of drugs known to have a negative impact on the risk of falling is considered. The article presents data on the frequency and structure of falls on the example of patients with cardiovascular diseases older than 75 years, treated in a multidisciplinary hospital. The analysis of the data showed a tendency of prevalence of the fact of falling in 1/3 patients (33,8%) in the first 5 days of hospital stay, which may be associated with high drug burden and the appointment of «new¼ drugs for the patient. The study noted that it was on the first day that the selection of therapy took place and additional drugs were often prescribed, leading to a state of polypragmasia. Analysis of individual groups of drugs was able to reliably confirm the relationship between the appointment of drugs that increase.

Ankle muscle activity modulation during single-leg stance differs between children, young adults and seniors.

PURPOSE: Incomplete maturation and aging-induced declines of the neuromuscular system affect postural control both in children and older adults and lead to high fall rates. Age-specific comparisons of the modulation of ankle muscle activation and behavioral center of pressure (COP) indices during upright stance have been rarely conducted. The objective of the present study was to quantify aging effects on a neuromuscular level. Thus, surface electromyography (SEMG) modulation and co-activity of ankle muscles during single-leg standing was compared in healthy children, young adults and seniors. METHODS: Postural steadiness (velocity and mean sway frequency of COP), relative muscle activation (SEMG modulation) and co-activation of two ankle muscles (tibialis anterior, TA; soleus, SO) were examined during single-leg stance in 19 children [age, 9.7 (SD 0.5) years], 30 adults [23.3 (1.5) years] and 29 seniors [62.7 (6.1) years]. RESULTS: Velocity of COP in medio-lateral and anterior-posterior directions, mean sway frequency in anterior-posterior direction, relative muscle activation (TA and SO) and co-activation revealed large age effects (P < 0.003, η p2 > 0.14). Post-hoc comparisons indicated higher COP velocities, anterior-posterior frequencies, relative SO activation and co-activation in children and seniors when compared with adults. Relative TA activation was higher in children and adults compared with seniors (P < 0.001). CONCLUSIONS: Increased postural sway in children and seniors seems to be counteracted with higher TA/SO co-activity and SO modulation. However, TA modulation is higher in children and adults, whereas seniors' TA modulation capacity is diminished. An aging-induced decline of TA motor units might account for deteriorations of TA modulation in seniors.

Effect of Acute Static Stretching on Lower Limb Movement Performance Using STABL Virtual Reality System.

CONTEXT: The effect of acute static stretching (ASS) on the lower limb reaction time (RT) has been recently questioned to decrease the risk of falling and injuries in situations requiring a rapid reaction, as in the cases of balance disturbance. OBJECTIVE: The main purpose of this study was to detect the effect of ASS on the lower limb RT using a virtual reality device. DESIGN: Two-group control group design. SETTING: Research laboratory. PARTICIPANTS: The control and experimental groups were formed randomly from 60 female university students. INTERVENTION: Each participant in the experimental group was tested before and after ASS for the quadriceps, hamstrings, and planter flexor muscles, and compared with the control group with warming-up exercise alone. The stretching program involved warming up in the form of circular running inside the lab for 5 minutes followed by stretching of each muscle group three times, to the limit of discomfort of 45 seconds, with resting period of 15 seconds between stretches. MAIN OUTCOME MEASURES: The measurements included the RT of the dominant lower-extremity using the dynamic stability program STABL Virtual Reality System (model no. DIZ 2709; Motekforce Link). RESULTS: There was a statistically significant reduction (F = 162, P < .05) in posttest RT between the 2 groups and significant decrease in RT after stretching in the experimental group (7.5%; P < .05). CONCLUSION: ASS of the lower limb muscles tends to decrease the lower limb RT and improve movement performance.

Instrumented gait analysis: a measure of gait improvement by a wheeled walker in hospitalized geriatric patients.

BACKGROUND: In an increasing aging society, reduced mobility is one of the most important factors limiting activities of daily living and overall quality of life. The ability to walk independently contributes to the mobility, but is increasingly restricted by numerous diseases that impair gait and balance. The aim of this cross-sectional observation study was to examine whether spatio-temporal gait parameters derived from mobile instrumented gait analysis can be used to measure the gait stabilizing effects of a wheeled walker (WW) and whether these gait parameters may serve as surrogate marker in hospitalized patients with multifactorial gait and balance impairment. METHODS: One hundred six patients (ages 68-95) wearing inertial sensor equipped shoes passed an instrumented walkway with and without gait support from a WW. The walkway assessed the risk of falling associated gait parameters velocity, swing time, stride length, stride time- and double support time variability. Inertial sensor-equipped shoes measured heel strike and toe off angles, and foot clearance. RESULTS: The use of a WW improved the risk of spatio-temporal parameters velocity, swing time, stride length and the sagittal plane associated parameters heel strike and toe off angles in all patients. First-time users (FTUs) showed similar gait parameter improvement patterns as frequent WW users (FUs). However, FUs with higher levels of gait impairment improved more in velocity, stride length and toe off angle compared to the FTUs. CONCLUSION: The impact of a WW can be quantified objectively by instrumented gait assessment. Thus, objective gait parameters may serve as surrogate markers for the use of walking aids in patients with gait and balance impairments.

Risk of falls in the rheumatic patient at geriatric age.

Evaluating the risk of falling of a geriatric rheumatic patient plays an essential role not only in planning and carrying out the physiotherapeutic process. The consequences of falls may be different and, although they do not always result in serious repercussions such as fractures or injuries, it is sufficient that they generate the fear of falling and cause a significant reduction in physical activity. Assessing functional capacity to define the risk of falling is of utmost importance in the case of patients after joint arthroplasty surgeries. The specificity of rheumatic patient's falls is determined by numerous factors. It is not always possible to avoid them. However, it becomes vital to include fall prevention in the rehabilitation process as well as to prepare the house for the needs of an elderly person so that they are safe and as self-dependent as possible.

Risk factors associated with falls in adult patients after stroke living in the community: baseline data from a stroke cohort in Brazil.

BACKGROUND: Individuals with stroke have a high risk of falling, and their fall predictors may differ from those of other populations. PURPOSE: To estimate fall frequency and identify factors related to fall occurrence in a sample of patients with stroke residing in the community. METHODS: Clinical data were collected from 150 consecutive stroke patients with independent gait, and the following scales were applied: modified Barthel Index (mBI), Timed Up & Go Test (TUG), and National Institutes of Health Stroke Scale (NIHSS). Univariate analysis was performed; variables with possible association (P < .1) were included in a logistic regression model. Receiver operating characteristic curves were used to identify the best cutoff point for TUG. RESULTS: Falls occurred in 37% of patients. In multivariate analysis, right hemisphere injury (odds ratio [OR], 2.621; 95% CI, 1.196-5.740; P = .016), time in TUG (OR, 1.035 for every increase in 1 second; 95% CI, 1.003-1.069; P = .034), and longer time since stroke onset (OR, 1.012 for every month increase; 95% CI, 1.002-1.021; P = .015) remained predictors. When we grouped individuals according to affected cerebral hemisphere, both hemispheres had similar accuracy, but TUG cutoff point was lower in individuals with right- versus left-hemisphere lesions. CONCLUSIONS: Patients with poor TUG performance, longer times since stroke onset, and right-hemisphere injury have particularly high fall rates, and TUG cutoff points for fall prediction vary according to cerebral hemisphere.

Effect of adding systematic desensitization to goal-directed paradigm on risk of falling in patients with stroke: a randomized controlled trial.

Background: Improvement in rehabilitation outcomes for patients suffering from chronic stroke can be attained through systematic desensitization of their fear of falling, which in turn reduces the risk of falling. Purpose: This study aimed to examine the effect of adding systematic desensitization to a goal-directed paradigm on functional performance, balance, risk of falling, and fear of falling among chronic ischemic stroke patients. Methodology: Two equally sized groups, each comprising 40 stroke patients of both sexes, were randomly divided. For 8 weeks, Group A received three sessions per week of combined treatment consisting of systematic desensitization and a goal-directed paradigm, while Group B received only the goal-directed paradigm. The Timed Up and Go (TUG) test and Dynamic Gait Index (DGI) were used to assess function performance; the Berg Balance Scale (BBS) and the Biodex Fall Risk Index (FRI) were used to evaluate balance; and the 16-item Fall Efficacy Scale-International (FES-I) was used to evaluate fear of falling. At baseline and after the treatment, all measurements were obtained. Results: Both groups (A and B) revealed a substantial increase in functional performance through a decrease in TUG scores and an increase in DGI. Additionally, there was a decrease in the risk of falling through an increase in the BBS scores and a decrease in the FRI. Furthermore, there was a decrease in the fear of falling, as measured using the FES-I, after treatment, with superior improvement in Group A with a p-value of <0.001. Conclusion: Systematic desensitization combined with a goal-directed paradigm has a superior effect on improving functional performance and reducing the risk of falling and the fear of falling in patients with stroke compared to a goal-directed paradigm alone.

Plantar fascia stiffness in patients with type 2 diabetes mellitus: Stiffness effect on fall risk and gait speed.

AIMS: The primary objective was to compare patients with type 2 diabetes mellitus (T2DM) and healthy peers in terms of plantar fascia (PF) stiffness, fall risk, and gait speed. The second objective was to examine the relationship between stiffness of PF and fall risk, gait speed. METHODS: Fifty patients diagnosed with T2DM (mean duration = 10.74 ± 7.07 years) were included. Myotonometer was used to evaluate the stiffness of PF. To assess the risk of falling, and gait speed, the International Fall Efficiency Scale (FES-I) and the 4-Meter Gait Speed Test (4mGST) were used, respectively. RESULTS: Compared to healthy controls, PF stiffness (right foot mean difference = 148.99 N/m, left foot mean difference = 113.13 N/m p < .001) was higher in the T2DM group. The FES-I and 4mGST scores were worse in the group with T2DM (p < .05). 12.8 % of FES-I and 23.4 % of 4mGST variance were explained by stiffness of PF. CONCLUSIONS: The results of the study showed that the stiffness of PF changed in patients with T2DM. There was a decrease in gait speed and an increase in the risk of falling as PF stiffness increased.
