The effects of mechanical hippotherapy riding on postural control, balance, and quality of life (QoL) in patients with stroke

PURPOSED

This study aimed to investigate the effects of exercises by mechanical hippotherapy devices on postural control, balance, mobility, and Quality of Life in patients with stroke.

MATERIAL AND METHODS

This was a randomized controlled clinical trial with a total of 30 which were randomly divided into two groups. The participants in the mechanical hippotherapy group (MHG) (n = 15) were given exercises with a mechanical hippotherapy device for 15 min in addition to intensive conventional treatments (45 min), while the control group (CG) (n = 15) received additional 15 min of postural control and balance exercises for five days per week for four consecutive weeks. The primary outcome was The Berg Balance Scale (BBS). Secondary outcomes were the Fugl-Meyer (FM) Rating Scale, Biodex Balance Measurement (BBM), Trunk Impairment Scale (TIS), the Timed Up and Go Test (TUG) and quality of Life Short Form (SF-36).

RESULTS

In the MHG, FM-Lower extremity score (-6.4, p = 0.024), FM-Upper extremity score (-12.87, p = 0.013), TIS (-5.87, p = 0.04) and TUG (5.73, p = 0.027) improved statistically significant compared to CG.

CONCLUSION

Exercises using mechanical hippotherapy devices could improve postural control, functional mobility and balance in patients with stroke. It may also improve the quality of life.

Effects of Hippotherapy on Postural Control in Children With Cerebral Palsy: A Systematic Review

PURPOSE

To summarize and update the current knowledge on the effectiveness of hippotherapy on postural control in children with cerebral palsy.

METHODS

Using a systematic review methodology, the electronic databases PubMed, Virtual Health Library, PEDro, Scielo, Embase, and Web of Science were searched for eligible articles from 2011 up to September 2021. Quality assessment of eligible studies was performed using the PEDro scale.

RESULTS

There were 239 identified studies. Eight clinical trials were selected. The total sample consisted of 264 individuals, with 134 allocated to the experimental group (hippotherapy) and 130 individuals to the control group (conventional therapy). Most studies had moderate to high methodological quality.

CONCLUSIONS

Hippotherapy can be an effective intervention to improve several aspects related to postural control, such as static balance (especially in the sitting posture), dynamic balance, and alignment (body posture) in children aged 3 to 16 years, particularly with spastic hemiplegia or diplegia.

WHAT THIS ADDS TO THE EVIDENCE

This review summarizes studies that explore potential effects of hippotherapy on postural control in children with cerebral palsy.

Breast Cancer: How Hippotherapy Bridges the Gap between Healing and Recovery-A Randomized Controlled Clinical Trial

BACKGROUND

Breast cancer is the most diagnosed women's cancer, and has a high survival rate. Despite great progress in detection and treatment, life reconstruction requires comprehensive cross-sectoral approaches between different disciplines and deeper consideration of the patient's challenges. Hippotherapy is an emerging specialized rehabilitation approach, performed by accredited health professionals and equine specialists, on specially trained horses via their movement, activating major paths for physical, mental, psychic and social reinforcement, and is synergistic to rehabilitative and supportive care.

METHODS

We conducted a randomized open, prospective, two-armed, controlled trial on the effectiveness of hippotherapy versus conventional supportive care on adult women with a diagnosis of breast cancer, after the period of primary treatment (surgery, chemotherapy, radiotherapy). The 6-month program included, in the treated group, an initial 1-week daily hippotherapy session, followed by three short 2-day sessions with an interval of 2 months between each, where the patients received conventional supportive care. The control group received 6 months of conventional supportive care. The primary end point was quality of life. Cognitive performances, fatigue, anxiety, depression, and body image were the secondary end points. Measurements were done through self-reported questionnaires.

RESULTS

We observed statistical differences in the evolution of the measured parameters over time between the two groups. The hippotherapy group showed a much faster, favorable and continuous improvement until the end of the program for each function assessed. The most striking improvements were observed in global quality of life, and fatigue, while breast cancer-specific quality of life, cognitive performance, anxiety and depression and body image showed a less marked but still statistically significant difference at the final post-treatment evaluation.

CONCLUSIONS

We demonstrate the therapeutic relevance of hippotherapy, a one-health approach, as a key initial stage after cancer diagnosis and treatment to foster recovery. Furthermore, hippotherapy has a strong impact on cancer treatments' efficiency and reconstruction of patient's life and ecosystem. This work reveals a layer of complexity that needs to be broadly considered.

Comparison of the Effect of Dressage Rider Skill Level on Physical Fitness Parameters and Posture on an Equestrian Simulator

In dressage riding, rider posture plays an important role in the performance of the exercises. The purpose of this study was to compare physical fitness and posture on an equestrian simulator between different competitive dressage rider skill levels. Participants (ten expert and twelve novice competitive dressage riders) performed a physiotherapeutic screening test and an equestrian simulator test. The expert rider group (G2) had less variability in both left (P = .002) and right (P = .021) rein force during medium canter on the simulator compared to the novice rider group (G1). The shoulder angle of the expert riders was larger in all gaits. These findings indicate that the ability to maintain a constant force on the reins and a dynamically stable hand position during riding on a simulator are important indicators for good rider performance. Expert riders presented a trend toward a more stable posture on the simulator as indicated by the reduced trunk variability (P = .034 vs. CV = 0.011) and smaller trunk ROM (P = .012 vs. CV = 0.011) and knee ROM (P = .033 vs. CV = 0.011) in the collected canter and collected walk respectively. These kinematic differences underscore their capability of maintaining a continued and constant force on the reins, but these findings require further research. No significant differences were found between groups in the physiotherapeutic screening. This underlines the difficulty in identifying the physical factors contributing to better rider performance. In conclusion, the current study shows that "stable rein contact" is the main difference between novice and expert competitive dressage riders on the simulator.

Effectiveness of Mechanical Horse-Riding Simulator-Based Interventions in Patients with Cerebral Palsy-A Systematic Review and Meta-Analysis

BACKGROUND

Mechanical horse-riding simulator (HRS) exercises are a type of therapy based on the use of robotic or mechanical devices that produces movement similar to a real horse with the aim of simulating hippotherapy. This review analyses the effectiveness of HRS therapies in patients with cerebral palsy (CP).

METHODS

A systematic review and a meta-analysis were carried out by searching studies in PubMed Medline, SCOPUS, Web of Science, CINAHL, PEDro and SciELO up until October 2022. We selected clinical trials that assessed the effectiveness of HRS therapy, compared to other interventions, in patients with CP. The main variables were gross motor function (its global score and dimensions, such as sitting ability), functional balance, spasticity, hip range of motion (ROM), posturographic balance and satisfaction. The risk of bias was assessed using the Cochrane Risk of Bias Tool. The pooled effect was calculated using Cohen's Standardized Mean Difference (SMD) for a 95% confidence interval (95% CI).

RESULTS

Twelve studies were included in the systematic review, and 10 were included in the meta-analysis, providing data from 343 patients with spastic diplegic CP. Our findings revealed that HRS plus physiotherapy is more effective than physiotherapy in improving the total gross motor function (SMD 0.98; 95% CI 0.35-1.62), sitting ability of the gross motor function (SMD 0.84; 95% CI 0.32-1.36) and functional balance (SMD 0.6; 95% CI 0.1-1.08), and HRS therapy is better than sham to improve pelvic abduction ROM (SMD 0.79; 95% CI 0.21-1.37).

CONCLUSIONS

Horse-riding simulator-based therapy is an effective therapy to improve gross motor function, functional balance and abduction pelvic ROM in children with CP, in comparison to physiotherapy or sham.

After 55 Years of Neurorehabilitation, What Is the Plan?

Neurological disorders often cause severe long-term disabilities with substantial activity limitations and participation restrictions such as community integration, family functioning, employment, social interaction and participation. Increasing understanding of brain functioning has opened new perspectives for more integrative interventions, boosting the intrinsic central nervous system neuroplastic capabilities in order to achieve efficient behavioral restitution. Neurorehabilitation must take into account the many aspects of the individual through a comprehensive analysis of actual and potential cognitive, behavioral, emotional and physical skills, while increasing awareness and understanding of the new self of the person being dealt with. The exclusive adoption by the rehabilitator of objective functional measures often overlooks the values and goals of the disabled person. Indeed, each individual has their own rhythm, unique life history and personality construct. In this challenging context, it is essential to deepen the assessment through subjective measures, which more adequately reflect the patient’s perspective in order to shape genuinely tailored instead of standardized neurorehabilitation approaches. In this overly complex panorama, where confounding and prognostic factors also strongly influence potential functional recovery, the healthcare community needs to rethink neurorehabilitation formats.

Neurorehabilitation through Hippotherapy on Neurofunctional Sequels of Stroke: Effect on Patients' Functional Independence, Sensorimotor/Cognitive Capacities and Quality of Life, and the Quality of Life of Their Caregivers-A Study Protocol

BACKGROUND

Stroke is a high burden illness and the second leading cause of worldwide disability with generally poor recovery rates. Robust benefits of hippotherapy, a novel neurorehabilitation approach, in functional recovery following various severe neurological disabling conditions has been shown. In the present study, we will analyze the effect of a hippotherapy program on the outcome of post-stroke patients in the first year post-stroke.

METHOD

A randomized controlled clinical trial on the effectiveness of hippotherapy (4 weeks/18 weeks hippotherapy/conventional neurorehabilitation) versus conventional neurorehabilitation alone (22 weeks) will be conducted over 48 weeks. In the treated group, one-hour daily hippotherapy sessions will be exclusively conducted during the hippotherapy's cycles, alternated with periods of conventional neurorehabilitation. A test battery will measure both the functional and psychological outcomes. The primary endpoint will be the patient's functional independence. The secondary endpoints will measure the sensorimotor function, autonomy, and quality of life, as well as the caregivers' quality of life.

RESULTS AND CONCLUSION

Individual brain connectome, life history and personality construct influence the brain's functional connectivity and are central to developing optimal tailored neurorehabilitation strategies. According to our current practice, hippotherapy allows the enhancement of substantial neuroplastic changes in the injured brain with significant neurological recovery. The protocol aims to confirm those issues. Trial registration in ClinicalTrials.gov NCT04759326 accessed on 19 February 2021.

Inter-Day Reliability and Changes of Surface Electromyography on Two Postural Muscles Throughout 12 Weeks of Hippotherapy on Patients with Cerebral Palsy: A Pilot Study

Cerebral palsy (CP) is an umbrella term covering a group of permanent developmental disorders of movement and posture characterized by highly variable clinical features. The aim of this study was to assess the short-term and mid-term effects of neurorehabilitation via hippotherapy on the contractile properties of two key postural muscles during functional sitting in such patients. Thirty-minute hippotherapy sessions were conducted biweekly for 12 weeks in 18 patients (18.1 ± 5.7 years old). Surface electromyography (EMG) was implemented bilaterally in rectus abdominis and adductor magnus. We quantitatively analyzed the amplitude of EMG signals in the time domain and its spectral characteristics in the frequency domain. EMGs were recorded at the beginning and end of each session on day one and at week six and week twelve. Statistical analysis revealed a substantial inter-day reliability of the EMG signals for both muscles, validating the methodological approach. To a lesser extent, while beyond the scope of the current study, quantitative changes suggested a more selective recruitment/contractile properties’ shift of the examined muscles. Exploring postural control during functional activities would contribute to understanding the relationship between structural impairment, activity performance and patient capabilities, allowing the design of neurorehabilitation programs aimed at improving postural and functional skills according to each individual’s needs. The present study provides basic quantitative data supporting the body of scientific evidence making hippotherapy an approach of choice for CP neurorehabilitation.
