Effects of Functional Progressive Strength Training on Gait Parameters and Walking Capacity in Children With Spastic Cerebral Palsy

In the outlined study, participants who fit the necessary inclusion and exclusion criteria are asked to provide written informed consent before taking part. The randomization process involves each participant drawing a number from a box: those who draw number one are placed in Group A (experimental group), while those drawing number two are placed in Group B (control group).

Group A undergoes a specialized treatment approach called Functional Progressive Resistance Exercise (FPRE), in addition to receiving conventional treatment. The FPRE regimen starts with a three-minute warm-up that includes range of motion mobilization and stretching exercises. This is followed by a series of resistance exercises, such as sit-to-stand activities, which increase in intensity over a six-week period, targeting specific percentages of body weight. The participants then engage in half-kneeling, standing up, and side-step-up exercises for 20 minutes each, with rest intervals. The session concludes with a two-minute cooldown. The protocol is designed to gradually increase the load carried by the participants, scaling up to five times, then 10 times, and eventually 15 times the initial weight, with a minimum of one minute of rest between sets. The exercises are calibrated through trial and error to find the maximum load that can be lifted for the defined number of repetitions and sets.

Group B participants receive conventional physical therapy aimed at maintaining muscle flexibility and improving motor function. Their routine includes an hour-long session three times a week, consisting of stretching exercises focused on muscles prone to tightness, such as the Achilles tendons, hamstrings, hip flexors, and adductors. Strength training targets specific muscle groups including hip flexors, knee extensors, and ankle dorsiflexors. The gait training in Group B starts in a controlled environment, such as walking between parallel bars, and progresses to more complex tasks like walking unassisted in open spaces, navigating different floor surfaces, and moving through obstacle-laden paths.

Both groups are reassessed after 12 weeks to evaluate the impact of their respective interventions on gait parameters and walking capacity, using a combination of direct observation, caregiver reports, and standardized assessment tools. The study aims to ascertain the relative efficacy of these two approaches in enhancing mobility and quality of life for children with spastic cerebral palsy.
