Hippotherapy in Children With Spinal Muscular Atrophy

The ability of the thorax to change shape

The examination will take place lying on your back. 3 position markers will be placed on each side of the thorax, in the area of the distal end of the sternum axes, at the level of the 3rd rib and at the lowest arch of the 10th rib. Their position during exhalation and inspiration will be measured, and the change in thorax circumference will be evaluated. The aim of this test is to objectify the change in respiratory stereotype. After therapy, investigators expect a greater ability of the thorax to change direction.

Sitting symmetry

Observations will be made by sitting on a therapy cylinder. There will be special markers on the body (on clothes) of children: lower angles of the scapulae axes, ridge of the iliac axes, sacroiliac joint (SI) on both sides and in the area of the L4 vertebra and navel. Investigators will measure the symmetry of these marks in each other's position and the movement in which the child will walk back and forth with his hands. Markers will be analyzed using Qualisys Motion Capture Systems 2020.3. Acceleration and change of position will be evaluated in the second time.

Work with the center of gravity

Observation will be performed by sitting on therapeutic cylinder. 3 position markers will be used on each side of the body, at the root of the palm, in the area of the SI joint and at the level of the temporomandibular joint. The change of markers will be measured from the starting position until the child is stretched to the side (torso tilt with lug) and forward (torso flexion with forearm). The monitoring child will be motivated to reach for the toy. The goal is to evaluate the stability of children. Investigators assume, that after therapy investigators can see better work with the center of gravity.

Muscle fatigue

Investigators will measure muscle fatigue after physical activity using surface EMG. The child will lie on his back, therapist will provide a toy in the area of his opposite knee. The child will stretch for a toy. This act will be 30 s. Investigators will evaluate activity m.obliquus externus abdominis at the beginning and end of this specific activity. Goal is to evaluate muscle fatigue. Investigators assume, that after intensive therapeutic program will be muscle fatigue lower.

Quality of life assessment

Parents of child with SMA will fill special questionnaire at the beginning and 4-5 weeks after end of the rehabilitation. The ICF score set, more precisely the ICF-based Documentation Form, the category Children with cerebral palsy Brief (below 6 years old),supplemented by some items from the basic rehabilitation set, will be used to evaluate the quality of life.

Monitoring of molecular biological indicators of rehabilitation

Samples treated in this way can be safely stored at room temperature for longer periods of time (up to three days or more). Blood samples stored in Ribonucleic acid (RNAlater)® Solution achieve RNA quality comparable to the quality of samples processed immediately according to commercial websites. The expected average total RNA yields will be about 2-4 /g / 0.5 ml all blood. Total RNA will be transcribed into complementary deoxyribonucleic acid complementary (cDNA) by reverse transcriptase. To avoid error, the expression of human lncRNA and internal endogenous gene (e.g., GAPDH) will be quantified using RNA obtained from blinded samples (i.e., concealment of sample origin allocation).
