Effect of hippotherapy on walking performance and gait parameters in people with multiple sclerosis

Comparison of the effects of mechanical hippotherapy and Cawthorne-Cooksey exercises in patients with multiple sclerosis: Randomized trial

BACKGROUND

Patients diagnosed with multiple sclerosis (MS) commonly encounter heightened postural instability and challenges in aligning their eyes, head, and bodily motions while engaging in specific tasks. This study aims to compare the effects of Cawthorne-Cooksey and mechanical hippotherapy exercises on fatigue, balance, gait, dizziness, and life quality in patients with MS.

METHODS

The MS patients were randomly divided into Cawthorne-Cooksey (n:25) and mechanical hippotherapy exercise (n:25) groups. In addition to the traditional physical therapy program, Cawthorne-Cooksey and hippotherapy exercises were applied to the groups 3 days a week, for 8 weeks. The trial's clinical number is NCT06005909. The Fatigue Severity Scale (FSS), Fatigue Impact Scale (FIS), Dizziness Handicap Inventory, Tinetti Balance and Gait Assessment Scale, and Ferrans&Powers Quality-of-Life Index were used for pre-and post-treatment assessment.

RESULTS

Both groups exhibited a significant decrease in FSS, FIS, and Dizziness Handicap Inventory scores, as well as an increase in Tinetti Balance and Gait Assessment Scale and Ferrans&Powers Quality-of-Life Index scores following treatment. In the inter-group comparison, the Tinetti balance and gait assessment and the Ferrans&Powers quality of life index scores were higher in the hippotherapy group compared to the Cooksey group.

CONCLUSIONS

Although both forms of physical activity have demonstrated effectiveness in reducing fatigue among individuals with MS, hippotherapy shows superior efficacy in enhancing balance, gait, and overall quality of life.

Patient and Clinician Perspectives of Physical Therapy for Walking Difficulties in Multiple Sclerosis

Gait speed is frequently the primary efficacy endpoint in clinical trials of interventions targeting mobility in people with multiple sclerosis (MS). However, it is unclear whether increased gait speed is a meaningful outcome for people living with MS. The purpose of this study was to identify the most important aspects of mobility for people with MS and physical therapists and to explore how patients and clinicians perceive whether physical therapy has been effective. Forty-six people with MS and 23 physical therapy clinicians participated in a focus group, one-on-one interview, or electronic survey. The focus group and interview data were transcribed and coded to identify themes. Free-text survey responses were also coded, and multiple-choice options were analyzed for frequency. Among people with MS, falls and difficulties getting out into the community were identified as highly important mobility limitations. Clinicians also identified falls and safety as a priority. Walking speed was infrequently described as a problem, and although gait speed is often measured by clinicians, improving gait speed is rarely a treatment goal. Despite their emphasis on safety, clinicians lacked certainty about how to objectively measure improvements in safety. People with MS evaluated physical therapy effectiveness based on the ease by which they can do things and acknowledged that "not getting worse" is a positive outcome. Clinicians evaluated effectiveness based on the amount of change in objective outcome measures and by patient and caregiver reports of improved function. These findings indicate that gait speed is not of major importance to people with MS or physical therapy clinicians. People with MS want to be able to walk further and without an assistive device, and they want to avoid falls. Clinicians want to maximize safety while improving functional ability. Clinicians and patients may differ in their expected outcomes from physical therapy.

Predictors of Step Length from Surface Electromyography and Body Impedance Analysis Parameters

Step length is a critical hallmark of health status. However, few studies have investigated the modifiable factors that may affect step length. An exploratory, cross-sectional study was performed to evaluate the surface electromyography (sEMG) and body impedance analysis (BIA) parameters, combined with individual demographic data, to predict the individual step length using the GAITRite® system. Healthy participants aged 40−80 years were prospectively recruited, and three models were built to predict individual step length. The first model was the best-fit model (R2 = 0.244, p < 0.001); the root mean square (RMS) values at maximal knee flexion and height were included as significant variables. The second model used all candidate variables, except sEMG variables, and revealed that age, height, and body fat mass (BFM) were significant variables for predicting the average step length (R2 = 0.198, p < 0.001). The third model, which was used to predict step length without sEMG and BIA, showed that only age and height remained significant (R2 = 0.158, p < 0.001). This study revealed that the RMS value at maximal strength knee flexion, height, age, and BFM are important predictors for individual step length, and possibly suggesting that strengthening knee flexor function and reducing BFM may help improve step length.

Benefits of Equine-Assisted Therapies in People with Multiple Sclerosis: A Systematic Review

This systematic review aimed to provide an up-to-date analysis of the effects of equine-assisted therapies (EAT) in people with multiple sclerosis (PwMS). The Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines were followed to conduct this systematic review. PubMed and Web of Science databases were employed in the search, which ended in February 2022. The risk of bias analysis was performed using the Evidence Project tool. After removing duplicates, thirty-nine studies were identified. However, only ten fulfilled the inclusion criteria and were included in this systematic review. Therefore, a total of 195 PwMS, aged between 40.3 and 51.3, were included in this systematic review. EAT-based interventions had a mean length of 13.6 weeks with a session´s frequency ranging from ten to once a week. All sessions involved real horses and lasted a mean of 34.4 min. Among the included articles, four were randomized controlled trials (RCT), four did not perform randomization, and two employed a prepost design without a control group. RCTs showed positive effects on quality of life, fatigue, balance, spasticity, and gait speed. Furthermore, non-RCT showed improvements in balance, spasticity, and postural control (postural control was not assessed in RCT studies). Importantly, significant effects were only observed when the comparison group was inactive or followed usual care. Therefore, EAT is a promising and effective therapy to improve quality of life, fatigue, balance, spasticity, and gait speed in PwMS. However, since comparison groups are heterogeneous, results could vary depending on the research design. Moreover, the inclusion of noncontrolled studies (in order to have a wide perspective of the state of art) could increase the risk of bias and make the results be taken with caution.

Physical Activity and the Health of Wheelchair Users: A Systematic Review in Multiple Sclerosis, Cerebral Palsy, and Spinal Cord Injury

OBJECTIVE

To understand the benefits and harms of physical activity in people who may require a wheelchair with a focus on people with multiple sclerosis (MS), cerebral palsy (CP), and spinal cord injury (SCI).

DATA SOURCES

Searches were conducted in MEDLINE, Cumulative Index to Nursing and Allied Health, PsycINFO, Cochrane CENTRAL, and Embase (January 2008 through November 2020).

STUDY SELECTION

Randomized controlled trials, nonrandomized trials, and cohort studies of observed physical activity (at least 10 sessions on 10 days) in participants with MS, CP, and SCI.

DATA EXTRACTION

We conducted dual data abstraction, quality assessment, and strength of evidence. Measures of physical functioning are reported individually where sufficient data exist and grouped as "function" where data are scant.

DATA SYNTHESIS

No studies provided evidence for prevention of cardiovascular conditions, development of diabetes, or obesity. Among 168 included studies, 44% enrolled participants with MS (38% CP, 18% SCI). Studies in MS found walking ability may be improved with treadmill training and multimodal exercises; function may be improved with treadmill, balance exercises, and motion gaming; balance is likely improved with balance exercises and may be improved with aquatic exercises, robot-assisted gait training (RAGT), motion gaming, and multimodal exercises; activities of daily living (ADL), female sexual function, and spasticity may be improved with aquatic therapy; sleep may be improved with aerobic exercises and aerobic fitness with multimodal exercises. In CP, balance may be improved with hippotherapy and motion gaming; function may be improved with cycling, treadmill, and hippotherapy. In SCI, ADL may be improved with RAGT.

CONCLUSIONS

Depending on population and type of exercise, physical activity was associated with improvements in walking, function, balance, depression, sleep, ADL, spasticity, female sexual function, and aerobic capacity. Few harms of physical activity were reported in studies. Future studies are needed to address evidence gaps and to confirm findings.

Effectiveness of equine-assisted therapies for improving health outcomes in people with multiple sclerosis: A systematic review and meta-analysis

BACKGROUND

Scientific evidence has shown that equine-assisted therapies (EAT) lead to improvements in the physical function and the quality of life (QoL) of people with disabilities through the practice of hippotherapy or therapeutic riding (TR). There is a need to confirm whether people with multiple sclerosis (PwMS) can also benefit from its practice. This review aimed to systematically evaluate and meta-analyze the available data on the potential health benefits of EAT in PwMS.

METHODS

Four electronic databases (MEDLINE/PubMed, Web of Science, SPORTDiscus, and Scopus) were searched systematically from their inception until June 2021 for randomized controlled trials (RCTs) and comparative studies that provided information regarding the effects of EAT on PwMS. The studies' methodological quality assessment was performed using the PEDro and the MINORS scales. For the meta-analysis, heterogeneity across studies was quantified using the I² statistic. Fixed-effect or random-effects models were applied to obtain the pooled results in the case of low (I² < 30%) or high (I² > 30%) heterogeneity values, respectively. Standardized mean differences (SMD) and 95% confidence intervals (CIs) were calculated to assess the change in each outcome.

RESULTS

After removing duplicated studies, 234 results were retrieved by the literature search and 11 were eligible for full text search. Finally, 9 studies with a methodological quality ranging from good to low quality met the inclusion criteria. Six of them focused on hippotherapy and 4 of them were included in the quantitative analysis. Totally, 225 PwMS patients were evaluated. Findings from the meta-analysis indicated that this therapy improved static (SMD = 0.42; 95% CI: 0.05, 0.78) but not dynamic balance (SMD = 0.51; 95% CI: -0.04, 1.06), while significant benefits were observed on the patients' QoL (SMD = 0.37; 95% CI: 0.00, 0.73). Hippotherapy showed effectiveness for reducing self-perceived fatigue (SMD = 0.70; 95% CI: 0.33, 1.07), while TR showed mixed effects on balance and QoL.

CONCLUSION

The actual evidence on the effectiveness of EAT in PwMS is mainly limited to hippotherapy. This rehabilitation approach seems to have beneficial effects on static balance, QoL and fatigue, but not directly on gait and dynamic balance. Altogether, the findings suggest that hippotherapy could be incorporated as a complementary therapy when developing comprehensive care plans for PwMS.

Effects of hippotherapy on postural balance, functional mobility, self-perceived fatigue, and quality of life in people with relapsing-remitting multiple sclerosis: Secondary results of an exploratory clinical trial

BACKGROUND

Multiple sclerosis (MS) results in worsening of postural balance, functional mobility, and self-perceived fatigue as influences of quality of life.

OBJECTIVE

To examine the effects of hippotherapy on postural balance, functional mobility, self-perceived fatigue, and quality of life in people with MS.

METHODS

Participants were assigned into a hippotherapy intervention group (n= 17) or a control group (n= 16). The intervention included 16 sessions of 30-minutes of hippotherapy conducted twice a week whereas the control group was maintained their therapeutic routine. Postural balance was evaluated as CoP speed (cm/s) and CoP 95% elliptical area (cm²) using a force platform under 4 experimental conditions: stable surface/ eyes open, stable surface/ eyes closed, foam surface/ eyes open, and foam surface/ eyes closed. Functional mobility was evaluated by the Timed Up and Go (TUG) test. The Fatigue Severity Scale (FSS) and Modified Fatigue Impact Scale (MFIS) measured perceived fatigue, and the Functional Assessment of Multiple Sclerosis (FAMS) measured quality of life. The data were examined using mixed model ANOVA with Bonferroni post hoc.

RESULTS

CoP speed and CoP 95% elliptical area (p < .05) significantly decreased across all testing conditions for the intervention group compared with control. The TUG improved over time in the intervention group (p = .001) as did the FSS (p < .001). In addition, there was also an improvement for the score and all the MFIS domains (p < .005) for the intervention group compared with control and for FAMS improved over time in the intervention group (p < .05).

CONCLUSION

Hippotherapy improved postural balance, functional mobility, fatigue, and quality of life in people with relapsing-remitting MS. This suggests that hippotherapy may be a useful approach for complimentary treatment among people with MS.

Kinematic Analysis of Lower Limb Joint Asymmetry During Gait in People with Multiple Sclerosis

The majority of people with Multiple Sclerosis (pwMS), report lower limb motor dysfunctions, which may relevantly affect postural control, gait and a wide range of activities of daily living. While it is quite common to observe a different impact of the disease on the two limbs (i.e., one of them is more affected), less clear are the effects of such asymmetry on gait performance. The present retrospective cross-sectional study aimed to characterize the magnitude of interlimb asymmetry in pwMS, particularly as regards the joint kinematics, using parameters derived from angle-angle diagrams. To this end, we analyzed gait patterns of 101 pwMS (55 women, 46 men, mean age 46.3, average Expanded Disability Status Scale (EDSS) score 3.5, range 1–6.5) and 81 unaffected individuals age- and sex-matched who underwent 3D computerized gait analysis carried out using an eight-camera motion capture system. Spatio-temporal parameters and kinematics in the sagittal plane at hip, knee and ankle joints were considered for the analysis. The angular trends of left and right sides were processed to build synchronized angle–angle diagrams (cyclograms) for each joint, and symmetry was assessed by computing several geometrical features such as area, orientation and Trend Symmetry. Based on cyclogram orientation and Trend Symmetry, the results show that pwMS exhibit significantly greater asymmetry in all three joints with respect to unaffected individuals. In particular, orientation values were as follows: 5.1 of pwMS vs. 1.6 of unaffected individuals at hip joint, 7.0 vs. 1.5 at knee and 6.4 vs. 3.0 at ankle (p < 0.001 in all cases), while for Trend Symmetry we obtained at hip 1.7 of pwMS vs. 0.3 of unaffected individuals, 4.2 vs. 0.5 at knee and 8.5 vs. 1.5 at ankle (p < 0.001 in all cases). Moreover, the same parameters were sensitive enough to discriminate individuals of different disability levels. With few exceptions, all the calculated symmetry parameters were found significantly correlated with the main spatio-temporal parameters of gait and the EDSS score. In particular, large correlations were detected between Trend Symmetry and gait speed (with rho values in the range of −0.58 to −0.63 depending on the considered joint, p < 0.001) and between Trend Symmetry and EDSS score (rho = 0.62 to 0.69, p < 0.001). Such results suggest not only that MS is associated with significantly marked interlimb asymmetry during gait but also that such asymmetry worsens as the disease progresses and that it has a relevant impact on gait performances.

Personality of patients with multiple sclerosis and the use of hippotherapy

BACKGROUND

Hippotherapy is an acknowledged form of rehabilitation for multiple sclerosis (MS) in Poland, but is still rarely used. The aim of the study was to assess the differences in the intensity of the personality traits of patients with MS who use and who do not use hippotherapy.

METHODS

The examination covered 92 patients with MS, aged 15-81 years old (85.9% women), average age 41.78 (± 15.02) years old, both using hippotherapy and not using this method of rehabilitation. The NEO-FFI Personality Inventory has been used for the study of personality traits. Socio-demographic and clinical data, as well as information regarding the use of hippotherapy, has been collected with the assistance of a self-designed survey.

RESULTS

For all of the patients, the trait expressed with the greatest intensity was conscientiousness (31 ± 7.51), and the least-expressed trait was neuroticism (24±10.42). 46% of the patients used hippotherapy and, compared to the non-users, they had a significantly greater level of agreeableness (34 v. 29, P<.001) and conscientiousness (33 v. 29, P=.009). Hippotherapy was most often used by the elderly patients (age average 49 ± 13.7, years old), while the average age of the non-users was 36 ± 13.6, years old (P<.001). Gender, education, place of residence, and economic status did not affect the choice of hippotherapy as a rehabilitation method.

CONCLUSIONS

The patients who use hippotherapy had a significantly higher level of agreeableness, conscientiousness, and openness to experience. The most important trait influencing the decision to try hippotherapy was agreeableness.
