Impact of a Pilates intervention on physical function in children with generalised joint hypermobility and chronic musculoskeletal pain: A single-case experimental design

Abstract

Aim: To assess the impact of a Physiotherapist-led Pilates Intervention for school aged children with Generalised Joint Hypermobility (GJH) on pain, physical function and Health Related Quality of Life (HRQoL).

Methods: Three children aged 8-12 years with GJH participated in an 8 week Physiotherapist-led Pilates Intervention within a single-case experimental design (multiple baseline design). Repeated measures were collected during baseline, intervention, withdrawal and follow-up, for: (i) pain, (ii) physical function as measured by muscle strength, postural control, fatigue and activity levels and (iii) HRQoL.

Results: Within the intervention phase, two children showed reduced fatigue and one child improved in muscle group strength of hip abduction (gluteus medius) and scapula adduction/rotation (rhomboideus major/minor) and HRQoL. No improvements were seen in pain or postural control. Within the early withdrawal phase all children showed improved strength for at least two muscle groups and one child showed reduced fatigue, pain (worst in last week) and improved postural control (functional reach lateral).

Conclusions: Pilates may provide an effective intervention for children with GJH to reduce fatigue and improve muscle strength and HRQoL. Limited conclusions can be made regarding pain and postural control. Further research with a longer Pilates duration is needed to confirm the dose and benefits for this population.
