This study was designed to assess the effect of a 12-week aquatic-based plyometric (Aqua-PLYO) training on postural control and functional performance in children with hemiparetic cerebral palsy (h-CP). Fifty-six children with h-CP were randomly allocated to the Aqua-PLYO group (n = 28, received an Aqua-PLYO training program, trice/week, over 12 weeks) or the control group (n =28, received standard rehabilitation). Both groups were assessed for postural control and functional performance pre and post-treatment.
Fifty-six children with h-CP were recruited from the Physical Therapy Outpatient Clinic of College of Applied Medical Sciences, Prince Sattam bin Abdulaziz University, King Khalid Hospital, and a tertiary referral hospital, Al-Kharj, Saudi Arabia. Their age ranged between 12 and 16 years, were functioning at levels I or II on the Gross Motor Function Classification System, and had spasticity level 1 or 1+ per the Modified Ashworth Scale. Children were excluded if they had fixed deformities, had leg-length discrepancy, underwent neuromuscular or orthopedic surgery in the last 12 months, submitted to BOTOX injection in the past 6 months, attentional neglect, cardiopulmonary problems preventing them from performing high-intense exercise training.
Outcome measures
The Aqua-PLYO group received a 12-week Aqua-PLYO training, 45 minutes per session, three times a week for 12 consecutive weeks, in conformity with the National Strength and Conditioning Association guidelines and American Academy of Pediatrics safety standards. The Aqua-PLYO program consisted of ten unilateral and bilateral lower limb plyometrics in the form of hopping/bounding/jumping activities conducted in a water medium. The Aqua-PLYO training included a warm-up for 10 minutes and a cool-down for10 minutes. The control group received the usual physical therapy care, 45 minutes per session, three times a week for 12 consecutive weeks. The program consisted of advanced balance training, and gait training exercises, postural and flexibility exercises, strength training exercises.

| Measure | Description | Time Frame |
|---|---|---|
| Directional Control | The amount of movement demonstrated in the desired direction, i.e. towards the target, to the amount of external movement in the opposite direction of the target, expressed as a percentage. | 2 months |
| Reaction time | The time, taken by an individual to start shifting his center of gravity from the static position after the cue, measured in seconds | 2 months |
| Movement Velocity | The average speed at which the center of gravity shifts, measured in degree/second | 2 months |
| EndPoint Excursion | The distance willingly covered by the subject in his very first attempt towards the target, expressed as a percentage (%) | 2 months |
| Maximum Excursion | The distance, the subject actually covered or moved his center of gravity toward a target, expressed as a percentage (%) of the dynamic limit of stability | 2 months |
| Functional lower limb strength | the functional strength of lower limbs was measured by the 30-second sit-to-stand test. The test determines the number of sit-to-stand task repetitions performed within 30 seconds. The higher number of repetitions indicates better performance. | 2 months |
| Functional mobility | Functional mobility was assessed by Timed Up and Down Stairs test. the test measures the time (second) that the subject takes to go upstairs, turn around, and come back down. Shorter time indicates better performance. |

| Gait balance | Gait balance was measured by the Dynamic Gait Index. The dynamic gait index quantified the ability of the participant to maintain walking balance while responding to different task demands, through various dynamic conditions. The index includes eight items, walking on level surfaces, changing speeds, head turns in horizontal and vertical directions, walking and turning 180 degrees to stop, stepping over and around obstacles, and stair ascent and descent. Each item is scored on a scale of 0 to 3, with 3 indicating normal performance and 0 representing severe impairment. The best possible score is 24. Higher scores mean a better outcome. | 2 months |
