Analysis of strength and electromyographic activity of lower limbs of individuals with down syndrome assisted in physiotherapy and hippotherapy.

INTRODUCTION: one of the characteristics of Down Syndrome (DS) is muscle hypotonia. Different therapeutic approaches have a positive influence, between them Physiotherapy applications with different therapeutic approaches such as Hippotherapy have a positive effect on the physical health and quality of live of individuals with DS. OBJECTIVE: to evaluate the effects of both treatments on the strength and electromyographic activity of the lower limbs of children and adolescents with DS. METHODS: fourteen individuals, aged between 10 and 18 years, participated in two groups: Physiotherapy group (n = 5) and Hippotherapy group (n = 9). Thirty interventions were performed for each type of therapy, once a week, lasting 30 min. Pre and post-interventions, the 30-Second Chair Stand Test (30s-CST) was used to assess the strength of the lower limbs and the surface electromyography equipment (EMG 800RF) to assess the lower limb myoelectric activity. RESULTS: there was a reduction in the post-intervention electromyographic values for both treatments (p˂0.001), with significantly less myoelectric activity in Hippotherapy compared to Physiotherapy for all evaluated muscles (p˂0.001) and a significant increase in muscle strength for the Hippotherapy, post-intervention group (p = 0.0007). CONCLUSION: Physiotherapy and Hippotherapy are interventions that promote positive changes in the myoelectric activities of individuals with DS. However, only hippotherapy promoted an increase in strength of the lower limbs.

Electromyographic analysis of stomatognathic muscles in elderly after hippotherapy.

The aging process affects the entire human body, including the stomatognathic system, and can trigger not only occlusal but also postural imbalances involving other muscular chains. Hippotherapy has been used to promote cervical, postural, and balance control in individuals with diverse impairments. The present study used electromyography to evaluate the masseter and temporal muscles in an elderly population pre- and post-hippotherapy. Participants included 17 individuals, mean age 66,5±7 years. Electromyographic recording of the bilateral masseter and temporal muscles was performed during the postural resting condition and activities that involved the active participation of these muscles in different conditions. The practitioner performed no other type of activity or exercise during the intervention because the objective is to evaluate the effect of the three-dimensional movement provided by the horse. Raw electromyographic data were tabulated using commercially available software (IBM® SPSS® Statistics 234.0) and subjected to statistical analysis, in which p ≤ 0.05 was considered to be statistically significant. Post-hippotherapy, there was lower electromyographic activity for the masseter and temporalis muscles in all the static mandibular tasks, with significant effect for time for the right temporal muscle (p = 0.038), the left temporal muscle (p = 0.028) and in the all dynamic mandibular tasks for the left temporal muscle (p = 0.025) and the left masseter muscle (p = 0.027). Hippotherapy promotes a reduction in the myoelectric activity of the masticatory muscles of elderly individuals.

Impact of hippotherapy for balance improvement and flexibility in elderly people.

INTRODUCTION: The decrease in functional ability, strength, balance, flexibility, agility, and coordination owing to neurological and muscular changes is one of the characteristic features of the human aging process. Hippotherapy has been highlighted as a therapeutic approach with physical and psychological benefits for this section of the population. However, the effects of hippotherapy in elderly people need to be further studied by assessing their balance and flexibility. METHODS: Thirty elderly people were recruited and divided into two groups; 15 in the Hippotherapy Group (HG), and 15 in the control group (CG) (aged 66.07 ±â€¯5.80 and 68.47 ±â€¯5.85 years, respectively). The HG received ten 30-min sessions of hippotherapy once a week. Assessment included the Berg Balance Scale (BBS), the Timed Up and Go test (TUG), the Functional Reach Test (FRT)and the Sit-and-Reach Test with the Well's box before the first and after the tenth session of hippotherapy; and the Sit-and-Reach Test before and after each session. RESULTS: The HG demonstrated a significant difference in the TUG test execution time and the FRT scores before and after the hippotherapy sessions (p = 0.036, p = 0.030, respectively), indicating an improvement in functional range. The examination of flexibility with the Wells's box also revealed a significant difference in the rates (cm) before and after 10 sessions of the hippotherapy for the HG (p = 0.033). CONCLUSIONS: The present findings showthat hippotherapy improved elderly people's functional mobility, dynamic balance, and flexibility. These results will guide professionals who treat this population.

Effect of horse riding equipment in activity of trunk and lower limb muscles in equine-assisted therapy

Equine-assisted therapy uses the horse in rehabilitation and/or education of people, such as Down syndrome(SD), cerebral palsy(PC)and intellectual disability(DI). In context, the rehabilitation program and horse riding equipment should be usedaccording to the specific characteristics of each individual, becoming an ally in the quest for excellence in equine-assisted therapy programs. The aim was to evaluate the effect of riding equipment used in equine-assisted therapy on the muscular activityof trunk and lower limb of individuals with SD, PC and DI. The study included 15 individuals equally assigned to each group: SD, PC and DIwith a mean age of 16.2 (±1.10), 16 (±1.22)e 16 (±0) years,respectively. The analysis of muscle activity was performed through surface electromyography, using four variations of horse riding equipment: saddle with and without feet supported on the stirrups and blanket with and without feet supported on the stirrups. Sigma Stat 3.5®software was used for statistical analysis.The Shapiro Wilk's test was used for normality of the data, the Bartlett test for homogeneity of the variances and the Kruskal-Wallis test for repeated measures with no normal distribution.Statistically significant differences were observed forp<0.05.The SDgroup presented a greater muscular activity of trunk and lower limbs with blanket equipment without the feet supported in the stirrups (H = 15.078, p = 0.002), as in the DI group (H=8.302, p = 0.040), while inPCgroup was the saddle with feet supported in the stirrups (H=11.137,p = 0.011). The choice of riding equipment used in equine-assisted therapy interferes differently in the pattern of muscular activation of the trunk and the lower limbs, according to the pathological processes of the practitioners. It should be an important aspect to consider when planninga treatment.

Analysis of the electromiographic activity of lower limb and motor function in hippotherapy practitioners with cerebral palsy.

OBJECTIVE: Investigation of the effects of hippotherapy treatment on lower limb muscle activity and gross motor function in subjects with cerebral palsy (CP), comparing them to a group of subjects with adequate motor development. METHODS: Evaluation was made of seven individuals with spastic diparetic CP, average age 9.3 (±3.3) years (CP group), Gross Motor Function Classification System (GMFCS) levels I and II, and eight individuals with adequate motor development, average age 10.9 (±3.2) years (control group). The groups were submitted to 25 sessions of hippotherapy, each lasting 30 min, on a weekly basis, and the muscle activity of the lower limbs was evaluated using surface electromyography during the 1st, 10th, 20th, and 25th sessions. For the CP group, Gross Motor Function Measurement (GMFM-88) was performed before and after hippotherapy treatment. RESULTS: There was higher muscle activity in the 10th session, compared to the other sessions, with greater activity of the tibialis anterior muscles, for both groups studied. After treatment, the CP group showed significant improvement in the GMFM total score, and in the scores for dimensions D and E. CONCLUSION: Hippotherapy sessions improved the muscle responses in both groups, and improved the gross motor function of the subjects with CP.

Activation of lower limb muscles with different types of mount in hippotherapy.

OBJECTIVES: To analyze muscle activation of lower limbs (LL) of subjects in hippotherapy sessions. METHODS: The study included 10 healthy subjects, five male and five female, with an average age of 24.03 (±4.06) years. Subjects underwent four hippotherapy sessions of 30 min with interval of one week, and each session was performed with a different type of mount material in the following order: 1st performed with saddle and feet in the stirrups (S1), 2nd with saddle and feet off the stirrups (S2), 3rd with blanket and feet off the stirrup (S3) and 4th with blanket and feet in the stirrups (S4). Surface electromyographies were performed at 1, 10, 20 and 30 min of session, and the electrodes were placed on muscle bellies bilaterally on the muscles rectus femoris, vastus medialis, vastus lateralis and tibialis anterior. RESULTS: The analysis of muscle activity during these four sessions showed a significant difference in muscle recruitment in LL, and sessions with blanket and feet in the stirrups provided greater muscle activation of quadriceps and tibialis anterior with the horse at step gait (p = 0.0002). CONCLUSION: The results suggest that feet positioned in the stirrups is a relevant factor for greater muscle recruitment in LL to maintain postural balance while riding, especially using a blanket as mount material for ride a horse.

Electromyographic evaluation of the lower limbs of patients with Down syndrome in hippotherapy / Avaliação eletromiográfica dos membros inferiores de pacientes com síndrome de Down na equoterapia

Hippotherapy is a therapeutic method that uses the horse's movement to achieve functional results in practitioners with Down syndrome (DS), who present motor and neurophysiological changes that affect the musculoskeletal system. Evaluating the motor behavior related to the control and the improvement of muscle activation in practitioners with Down syndrome subjected to hippotherapy. 10 practitioners were divided into two groups: Down Group (DG) ­ practitioners with DS, and Healthy Group (HG) ­ practitioners with no physical impairment. The muscles gluteus medius, tensor fasciae latae, rectus femoris, vastus medialis, vastus lateralis, biceps femoris, tibialis anterior and gastrocnemius were evaluated by electromyography using gross RMS values, which correspond to muscle activation; the evaluations were performed on the 1st and 10th hippotherapy sessions (frequency: once a week), and after 2 months interval without treatment, they were performed on the 1st and 10th hippotherapy sessions (frequency: twice a week). It was noted that activation of the studied muscles increased with the passing of sessions, regardless the weekly frequency of attendance; however, the period without treatment resulted in reduction of this effect. Practitioners with DS presented satisfactory changes in muscle activation pattern, in learning and in motor behavior during hippotherapy sessions.

Equoterapia é um método terapêutico que utiliza o movimento do cavalo para alcançar resultados funcionais, realizada em praticantes com síndrome de Down (SD), que apresentam alterações neurofisiológicas e motoras que afetam o sistema musculoesquelético. Avaliar o comportamento motor relacionado ao controle e melhora a ativação muscular em praticantes com SD submetidos ao tratamento equoterapêutico. Participaram dez praticantes divididos em dois grupos: grupo Down (GD) - praticantes com SD, e grupo Saudável (GS) - praticantes sem comprometimento físico. Os músculos glúteo médio, tensor da fáscia lata, reto femoral, vasto medial, vasto lateral, bíceps femoral, tibial anterior e gastrocnêmio foram avaliados por meio da eletromiografia, utilizando o valor de RMS bruto que corresponde à ativação muscular, e as avaliações foram realizadas na primeira e décima sessões de equoterapia (frequência: 01 vez por semana); e após intervalo de dois meses sem tratamento, foi realizada na primeira e décima sessões de equoterapia (frequência: 02 vezes por semana). Observou-se que a ativação muscular dos músculos estudados aumentou com o passar das sessões, independente da frequência semanal de atendimento; mas o período sem tratamento resultou em redução deste efeito. Os praticantes com SD apresentaram mudanças satisfatórias no padrão de ativação muscular, na aprendizagem e no comportamento motor no decorrer das sessões de equoterapia.
