Brief summary
The purpose of the study is to compare the effect between of whole-body vibration and gravity force stimulation on postural stability in children with Down syndrome.
Detailed description
Down Syndrome (DS) is one of genetic disorders characterized by some common clinical and functional features. Most children with Down syndrome have deficits in postural stability or balance, co-ordination, gait, and functional mobility throughout childhood and adulthood. Postural control dysfunctions are the most common problems found in children with DS leads them to be more inactive, which contributes to functional mobility problems. Several techniques that involve proprioceptive, vestibular, and visual inputs are so beneficial to children with DS. Whole-body vibration (WBV) is one of the training methods that use high-frequency mechanical stimuli generated by a vibrating platform and transmitted through the body, leading to bone loading and sensory receptor stimulation. Gravity force stimulation (GFS) has a strong impact on the child's sensory system helping to normalize the system through exercises that send strong messages to the brain to regulate the tactile, proprioceptive and vestibular components. Hence, there is need to compare between the effects of whole-body vibration training and gravity force stimulation on postural stability in children with Down syndrome.
Interventions
The designed physical therapy program include gentle stretching exercises, static muscle contraction, facilitation of trunk control from different positions, balance training from different positions on tilting board, facilitation of righting, protective and equilibrium reactions from different positions, facilitation of standing from different positions, gait training and, climbing stairs up and down.
OTHERWhole-Body Vibration
The designed physical therapy program (mentioned before) \+ Whole-body vibration (WBV) training, child will be asked to stand with slightly flexed knees (30 degrees of knee flexion), and both feet will be placed at an equal distance from the center of the platform to achieve an equal distribution of body weight over both feet. The device will set to produce a peak-to-peak sinusoidal vibration with an amplitude of 2 mm and a vibration frequency ranged from 25 to 30 Hz. WBV will applied for (30 sec. of WBV, 1 min rest, 10 repetitions), (45 sec. of WBV, 1 min rest, 10 repetitions), (60 sec. of WBV, 1 min rest, 10 repetitions) in the 1st, 2nd. and 3rd. months respectively.
OTHERGravity Force Stimulation
The designed physical therapy program (mentioned before) \+ Gravity force stimulation child will be asked to maintain his balance on GFS during each of the following positions as a progression (standing and walking on the surface of two beams connecting the two boxes - standing and walking crossly on the surface of one beam connecting the two boxes - standing and walking sideward on the surface of one beam connecting the two boxes - standing and walking on the edge of the two beams - standing and walking on the edge of one beam: most difficult)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postural Stability | Up to 12 weeks | Biodex Stability System will be used to measure overall stability index, anteroposterior stability index and mediolateral stability index. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Functional Mobility | Up to 12 weeks | Six-minute walk test will be used for measuring functional mobility. It is a sub-maximal test of aerobic capacity, in which the subjects walk as far as possible in 6 minutes (min.) around a premeasured distance |
