Effects of Stretch-shortening Cycle Exercises Postural Control in Down Syndrome

Not Applicable

Completed

• Conditions: Down Syndrome
• Interventions: Other: trampoline-based stretch-shortening cycle exercises; Other: Standard physical therapy

• Registration Number: NCT04966403
• Lead Sponsor: Qassim University

Brief Summary

To investigate the effect of a 3-month, trampoline-based stretch-shortening cycle (SSC) exercises on muscle strength and postural control in children with Down syndrome.

Detailed Description

a variety of physical therapy techniques are being used to improve lower limb muscle strength and postural control in children with Down syndrome including, but not limited to, progressive resistance training, hippotherapy, aquatic therapy, and isokinetic strength training. Stretch-shortening (SSC) exercises-also referred to as plyometric exercises, is a traditional form of resistance training that involves three-phase muscle contraction during dynamic movements (like jumping and hopping), where the muscle moves rapidly through the eccentric, isometric, and concentric phases.

Arm && Interventions

Group	Intervention	Description
trampoline-based stretch-shortening cycle exercises	trampoline-based stretch-shortening cycle exercises	In addition to the sPT, the SSC group received 15-minute SSC exercise sessions, twice weekly, with a total of 24 sessions over 12 successive weeks.
standard physical therapy	Standard physical therapy	Participants in the standard physical therapy received the standard physical therapy (sPT) program, which was conducted according to the needs of each participant and was generally concerned with building strength, enhancing developmental skills, boosting balance, coordination, and postural control, improving physical fitness, and minimizing the development of the compensatory movement patterns that children with DS are likely to develop.

Primary Outcome Measures

Name	Time	Method
Grade of Muscle strength by hand-held dynamometer	after 12 weeks	A calibrated hand-held dynamometer (Micro FET2, Hoggan Health Technologies Inc., UT, USA) was used

Secondary Outcome Measures

Name	Time	Method
Postural control index by Balance Biodex System	after 12 weeks	Postural stability indices were assessed through the Balance Biodex System (Biodex Medical Systems, Shirley, NY),
