Effects of Hippotherapy on Physical Fitness and Attention in Cerebral Palsy

Child Behavior Checklist; The Social Ability Scale consists of Sociality Scale and Academic Performance Scale. The Scale of Problem Behavior Syndrome consists of 113 items related to problem behavior, and 13 (Sociality, Learning Problem, Total Social Ability, Atrophy, Depression, social immaturity, thinking problems, attention problems, flying, aggression, internalization problems, externalizing problems, total problem behaviors). For each question, the scale is to be rated as 3-point Likert scale, the raw scores of all subscales are converted to standardized T scores . The higher the score, the higher the tendency toward problem behavior.

The %sedentary physical activity(%SPA), %light physical activity(%LPA), %moderate physical activity(%MPA), %vigorous physical activity(%VPA) during the day using ActiGraph(model GT3X, ActiGraph, Pensacola, FL, USA).

peak oxygen uptake(ml/kg/min) is a category of physical fitness, which is measured during graded submaximal exercise test. Higher values represent a better outcome.

GMFM-88 is a measure developed to evaluate the gross motor function changes in CP children. It has five components: lying and rolling, sitting, kneeling and crawling, standing, and walking. The score of each dimension is expressed as a percentage of the maximum score. The GMFM-66, which includes 66 items of the original 88 items. Item scoring is the same for the GMFM-88 and the GMFM-66. There is a scoring system with each item scored as 0, 1, 2, 3, or "not tested". A scoring key of 0 - does not initiate, 1 - initiates, 2 - partially completes, and 3 - completed, is used. Scoring the GMFM-66 requires the use of a computer program called the Gross Motor Ability Estimator (GMAE). Individual item scores are entered and a mathematical algorithm calculates an interval level total score. The total score is an estimate of the child's gross motor function. The range of total score in GMFM-66 is from 0 to 100. The range of % in GMFM-88 is from 0 to 100. Higher values represent a better outcome.

Steps(counts) was measured during the day using ActiGraph(model GT3X, ActiGraph, Pensacola, FL, USA)

Resting heart rate(beats/min) is a category of physical fitness, which is measured during graded submaximal exercise test. A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.

All patients performed a symptom-limited, treadmill exercise test using the Modified Naughton protocol. Respiratory exchange ratio(RER) were measured with a gas analyzer. RER is the ratio between the amount of carbon dioxide (CO2) produced in metabolism and oxygen (O2) used. A high RER (RER values≥1) indicates that carbohydrates are being predominantly used, whereas a low RER (RER values<1) suggests lipid oxidation.

All patients performed a symptom-limited, treadmill exercise test using the Modified Naughton protocol. In the recovery period, the patients walked for 2 minutes at a speed of 1.9 km/h and a grade of 0% and then sat down in a chair for the last 3 minutes (recovery). The Heart rate recovery (HRR) was defined as the difference between peak HR during the test and HR at 1 (HRR1), 3 (HRR3), and 5 (HRR5) minutes.

The Child Health Questionnaire™ (CHQ) is a family of generic person-reported outcomes measures to assess health-related quality of life for children and adolescents from 5-to-18 years of age. Child Health Questionnaire Parent Form 50 (CHQ-PF50) Questions; total 50 questions, 4 or 6 score Likert scale, the score range is from 0 to 100, higher values represent a better outcome. Scores can be analyzed at combined to derive an overall physical and psychosocial score, (CHQ Summary Scores).

① Stand up from the chair without support. ② Walk 3m from chair. ③ Turn around. ④ Sit back in the chair. Measure the time(second), higher values represent a worse outcome. Lower values represent a better outcome.

The 6 minute walk test assesses distance walked over 6 minutes as a sub-maximal test of aerobic capacity and endurance. Higher values represent a better outcome.

Blood pressure(mmHg) measured before graded exercise test using treadmill.

PBS is a functional balance scale adapted and customized from Berg Balance Scale for use with children. The PBS has been used initially to measure the balance functions for school-age children with mild-to-moderate motor impairments. The PBS is a 14-item, criterion-referenced measure, which examines functional balance in the context of everyday tasks. It can easily be administered and scored in less than 20 minutes using equipment commonly found in schools and clinics. Scoring (0-4) is based on how long a specific movement or position is performed, how long the position can be maintained, or how much assistance it requires. The range of total score is from 0 to 56. Higher values represent a better outcome.

ADHD(attention deficit hyperactivity disorder) rating scale; total 18 questions. Each item is scored from 0-3 points, The treatment effect is evaluated using Total score(0 ~ 54 points),attention-deficit scores (0 ~ 27 points) and hyperactivity/impulsivity score (0 ~ 27 points)

Self-Esteem Scale; total 10 question, Each item is scored from 1-4 points. Five of the ten questions are positive and five are negative. In the positive item, 1 = 'almost not so' and 4 = 'always'. In the negative item, the scores range from 10 to 40. The treatment effect is evaluated using the total score.

PedsQL 4.0; total 23 questions; Each item is scored from 0-4 points and scores are transformed on a scale from 0 to 100. Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. Thus, the scores range from 0 to 2300, higher values represent a better outcome.

Continuous Performance Test 3rd edition; It is a computerized assessment tool designed to measure attention-related problems, instructing them to respond to all stimuli except alphabet X, and instructing them to perform as accurately and quickly as possible. Detectability, Omission Errors, Commission Errors, Perseverations, HRT(hit reaction time), HRT SD (standard deviation), Variability, HRT Block Change, HRT ISI Change are used to assess respondents' performance on inattentiveness, impulsivity, sustained attention, and vigilance. It is used 9 T-scores to assess the level of attention problem.

An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs(electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time. This activity shows up as wave lines on an EEG recording. It is using Neuroscan Synamp2 amplifier(Compumedics USA, El Paso, TX, USA). For quantitative analysis, EEG without a handwriting is digitized by Fast Fourier Transformation. The square root of the magnitude of the EEG was calculated as the microvolt (uV) value, and the relative power is defined as the electrical force of the specific region divided by the electrical force in the whole region. The relative power of delta, theta, alpha, and beta waves and theta/beta ratio measured at the Fz, Cz, Pz electrode are used for the analysis. The value of theta/beta ratio is average as it approaches 0 and deviates from the mean as it gets away from 0.
