Aerobic Responses to FES-Assisted and Volitional Cycling in Children with Cerebral Palsy.

Recumbent stationary cycling is a potential exercise modality for individuals with cerebral palsy (CP) that lack the postural control needed for upright exercises. Functional electrical stimulation (FES) of lower extremity muscles can help such individuals reach the cycling intensities that are required for aerobic benefits. The aim of this study was to examine the effect of cycling with and without FES assistance to that of a no-intervention control group on the cardiorespiratory fitness of children with CP. Thirty-nine participants were randomized to a FES group that underwent an 8-week FES-assisted cycling program, the volitional group (VOL), who cycled without FES, or a no-intervention control group (CON) (15 FES, 11 VOL, 13 CON). Cadence, peak VO2, and net rise in heart rate were assessed at baseline, end of training, and washout (8-weeks after cessation of training). Latent growth curve modeling was used for analysis. The FES group showed significantly higher cycling cadences than the VOL and CON groups at POST and WO. There were no differences in improvements in the peak VO2 and peak net HR between groups. FES-assisted cycling may help children with CP attain higher cycling cadences and to retain these gains after training cessation. Higher training intensities may be necessary to obtain improvements in peak VO2 and heart rate.

Implementing treatment frequency and duration guidelines in a hospital-based pediatric outpatient setting: administrative case report.

BACKGROUND AND PURPOSE: Determining treatment frequency and duration of physical therapist services is an important component of outpatient pediatric physical therapist practice, yet there is little research available to inform these decisions. Treatment frequency guidelines (TFG) can assist decision making in guiding pediatric physical therapy. The purpose of this project was to examine the feasibility and application of implementing TFG in hospital-based pediatric outpatient physical therapy. PROJECT DESCRIPTION: Previously developed TFG were modified for use in our pediatric outpatient physical therapy department to include duration and were referred to as treatment frequency and duration guidelines (TFDG). In order to successfully implement the TFDG, there were 2 phases to the project. In phase 1, the staff were provided the guidelines and procedures in a staff meeting and via email using a PowerPoint presentation. Phase 2 was initiated due to the poor response of the staff in implementing the guidelines in their practice after phase 1. The format was changed to include formal re-education via small-group and one-on-one education sessions (phase 2). Chart reviews were completed to assess therapists' adherence to using TFDG. OUTCOMES: Therapists' adherence to use of TFDG increased following re-education: phase 1 (n=225 charts, 31% adherence) and phase 2 (n=197 charts, 90% adherence). DISCUSSION: Treatment frequency and duration guidelines may assist in guiding frequency and duration decisions in pediatric physical therapy. Education via in-person meetings may improve adherence among staff.

Evaluation of functional electrical stimulation to assist cycling in four adolescents with spastic cerebral palsy.

Introduction. Adolescents with cerebral palsy (CP) often have difficulty participating in exercise at intensities necessary to improve cardiovascular fitness. Functional electrical stimulation- (FES-) assisted cycling is proposed as a form of exercise for adolescents with CP. The aims of this paper were to adapt methods and assess the feasibility of applying FES cycling technology in adolescents with CP, determine methods of performing cycling tests in adolescents with CP, and evaluate the immediate effects of FES assistance on cycling performance. Materials/Methods. Four participants (12-14 years old; GMFCS levels III-IV) participated in a case-based pilot study of FES-assisted cycling in which bilateral quadriceps muscles were activated using surface electrodes. Cycling cadence, power output, and heart rate were collected. Results. FES-assisted cycling was well tolerated (n = 4) and cases are presented demonstrating increased cadence (2-43 rpm), power output (19-70%), and heart rates (4-5%) and decreased variability (8-13%) in cycling performance when FES was applied, compared to volitional cycling without FES assistance. Some participants (n = 2) required the use of an auxiliary hub motor for assistance. Conclusions. FES-assisted cycling is feasible for individuals with CP and may lead to immediate improvements in cycling performance. Future work will examine the potential for long-term fitness gains using this intervention.
