Clinical Trial Summary

This study was set out to compare the effect of paretic-limb-only plyometric training versus double-limb training on balance capability and gait symmetry in adolescents with unilateral cerebral palsy (U-CP). Sixty-nine children with U-CP were randomly allocated to the paretic-limb-only plyometric training group (n = 23; performed plyometric movements/exercises unilaterally using the paretic leg only), the double-limb plyometric training group (n = 23; performed plyometric movements/exercises bilaterally through both lower legs), or the Control group (n =23, received standard rehabilitation plus SSC exercises). All groups were assessed for gait-symmetry and balance capability pre and post-treatment.

Description:

Sixty-nine children with U-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 18 years, were functioning at levels I or II according to 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, underwent neuromuscular or orthopedic surgery in the last 12 months, submitted to BOTOX injection in the past 6 months, had attentional neglect, and if they had cardiopulmonary problems preventing them from performing high-intense exercise training. Outcome measures - Gait-symmetry Indices: Gait symmetry indices (Spatial and temporal) were measured through the portable GAITRite system. - Dynamic balance: The directional dynamic limit of stability (forward, backward, paretic, and non-paretic) and overall limit of stability were assessed using the Biodex balance system. All groups were trained for 45 minutes, twice per week, for 12 successive weeks. The paretic-limb-only plyometric training group performed plyometric movements/exercises unilaterally using the paretic leg only. The double-limb plyometric training group performed plyometric movements/exercises bilaterally through both lower legs. The plyometric training program consisted of five unilateral and five bilateral lower limb plyometrics in the form of hopping/bounding/jumping activities. The plyometric training was preceded by a warm-up for 5 minutes and ended up with a 5-min cooldown. The control group received the standard rehabilitation program, which comprised advanced balance training, and gait training exercises, postural and flexibility exercises, strength training exercises.

Intervention

Other:
• Unilateral plyometric training
The paretic-limb-only plyometric training group received a plyometric exercise program performed unilaterally through the paretic leg only for 45 minutes, three times per week for 12 successive weeks. The training was conducted under close supervision of a licensed pediatric physical therapist according to safety performance guidelines defined by the American Academy of Pediatrics and the US National Strength and Conditioning Association.
• Bilateral plyometric training
The double-limb plyometric training group received a plyometric exercise program performed bilaterally through the paretic and non-paretic legs for 45 minutes, three times per week for 12 successive weeks. The training was conducted under close supervision of a licensed pediatric physical therapist according to safety performance guidelines defined by the American Academy of Pediatrics and the US National Strength and Conditioning Association.
• Standard physical therapy
The control group received the standard physical rehabilitation program conducted for 45 minutes, thrice a week for 12 consecutive weeks, and consisted of advanced balance training, gait training, postural and flexibility exercises, and strength training exercises.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Spatial gait symmetry	The spatial gait symmetry index was measured about the step length of the paretic and non-paretic leg through the portable GAITRite system. Lower scores indicate a more symmetrical pattern.	2 months
Primary	Temporal gait symmetry	The temporal gait symmetry index was measured about the single-limb support time of the paretic and non-paretic leg through the portable GAITRite system. Lower scores indicate a more symmetrical pattern	2 months
Primary	Limit of postural stability	The capacity to control and move the center-of-gravity in various directions across their base-of-support was assessed utilizing the Biodex balance system. Values are expressed as accuracy % and higher scores mean better balance capability.	2 months
