Effects of massage on the mechanical behaviour of muscles in adolescents with spastic diplegia: a pilot study

Abstract

Calf muscles of five adolescents aged 12 to 15 years (three males, two females) with spastic diplegia were massaged for 14 minutes twice a week for 5 weeks in a controlled sequence, stretching the muscles transversely rather than longitudinally, without eliciting pain. Slow, passive test stretches were applied before and after massage. After massage, the range of movement was not consistently increased but, on average, greater force was needed to stretch the muscle than before massage. However, after massage the resting ankle angle sometimes changed so that the calf muscles were either shorter or longer. We suggest that these phenomena could be explained if massage resets sarcomere lengths which corrects for thixotropic effects (i.e. previous use modifies a muscle's mechanical behaviour). A redistribution on sarcomere lengths within muscles could also have reset proprioceptive feedback. The incidence of abnormal stretch reflexes during test stretches fell from 40 to 22%, comparing the first five sessions with the last five sessions. The amplitude of voluntary alternating ankle rotation increased in three participants. Motor skills were assessed with the Gross Motor Function Measure‐66 (GMFM‐66) 1 week before the test period, during the 5th week, and 12 weeks later. Our participants in Gross Motor Function Classification System (GMFCS) Levels I and II made sustained improvements in GMFM‐66 scores (6.4% at 5 weeks falling to 5.5% at 17 weeks), one increase being significant. One participant in GMFCS Level III improved significantly only after massage of all leg muscles for 30 weeks.

Development and Application of a Newly Designed Massage Instrument for Deep Cross-Friction Massage in Chronic Non-Specific Low Back Pain

“…Macgregor et al18 applied transverse friction massage to the calf muscle of patients with spastic diplegia and reported that, after massage, the amplitude of voluntary alternating ankle rotation increased and motor skill was improved. They suggested that massage resets sarcomere lengths and redistribution of sarcomere lengths within muscles could have reset proprioceptive feedback.…”

Muscle tone changes in the lower limbs of stroke patients induced by trunk stabilization exercises

“…To control spasticity, drug treatment, injection therapies, and operative treatments are being used; however, they have the risk of causing adverse reactions and their effects differ depending on the technical abilities of the operators 4 ) . Physical therapies that pose less risks of adverse reactions include massage therapy 5 ) , electrical stimulation treatment 6 ) , stretching stimulation therapy 7 ) , and vibration stimulation therapy 8 ) . Recent clinical studies found that trunk stabilization exercises influence the muscle tone of the distal part; however, there is still insufficient clinical evidence.…”

Potential effects of traditional massage on spasticity and gross motor function in children with spastic cerebral palsy: A randomized controlled trial

“…However, on comparison within groups, significant reduction in spasticity was observed in intervention group 9. Macgregor in a case series of five adolescents with spastic diplegia using Swedish massage for 12 weeks observed no significant reduction of spasticity 13…”
