Investigation of the Effects of Combining Whirlpool Therapy With Botulinum Toxin Treatment on Spasticity, Gait, and Motivation in Children With Cerebral Palsy
This study aims to investigate the effects of adding whirlpool therapy to standard rehabilitation in children with cerebral palsy who recently received botulinum toxin-A injections. Participants will be divided into two groups: one group will receive standard physiotherapy, while the other group will receive physiotherapy combined with whirlpool therapy. The effects of these interventions on spasticity, gait function, and motivation will be evaluated over a 12-week follow-up period.
This study was designed as a prospective, randomized, single-blind (assessor-blinded), parallel-group controlled clinical trial investigating the effects of combining whirlpool therapy with botulinum toxin type A (BoNT-A)-assisted rehabilitation on spasticity, gait, and motivation in children with hemiplegic cerebral palsy.
A total of 81 patients with hemiplegic cerebral palsy who had received botulinum toxin type A (BoNT-A) injections to selected lower extremity muscles within the previous week were initially evaluated. After applying the inclusion and exclusion criteria, 43 participants were enrolled in the study, and 38 patients were excluded. All botulinum toxin injections were performed using onabotulinumtoxinA by an experienced physiatrist with more than five years of clinical experience. Injection planning was individualized according to body weight, severity of spasticity, and targeted muscle groups.
Participants were randomly assigned in a 1:1 ratio to two groups (22 in the intervention group and 21 in the control group). Randomization was performed using a computer-generated random sequence by an independent researcher who was not involved in treatment or assessment. Allocation concealment was ensured using sequentially numbered, opaque, sealed envelopes. The study was conducted as a single-blind trial in which the outcome assessors were blinded to group allocation, while participants and therapists were not blinded because of the nature of the intervention.
Both groups received a conventional rehabilitation program for 4 weeks, 5 days per week, 1 hour per day. The program included range of motion (ROM) exercises for the upper and lower extremities, stretching and strengthening exercises, balance and coordination training, endurance exercises, and ambulation training, all delivered under physiotherapist supervision according to a standardized protocol.
In addition to conventional rehabilitation, the intervention group received whirlpool therapy three times per week for 4 weeks, with each session lasting 20 minutes, for a total of 12 sessions. All whirlpool therapy sessions were conducted under physiotherapist supervision.
Outcome measures were assessed at three time points: baseline (T0, week 0, pre-treatment), post-treatment (T1, week 4), and follow-up (T2, week 12). Spasticity was evaluated using the Modified Ashworth Scale (MAS) and the Modified Tardieu Scale (MTS). Functional mobility and standing/walking abilities were assessed using the Gross Motor Function Measure-88 (GMFM-88) dimensions D and E. Motivation was evaluated using the Pediatric Motivation Scale. Gait kinematics, including joint range of motion and peak flexion and extension angles of the hip, knee, and ankle, were analyzed using the DIERS 4D Motion Lab system. Functional walking performance was assessed using the 10-Meter Walk Test (10MWT).
