Mental techniques during manual stretching in spasticity--a pilot randomized controlled trial.

Area of Science:

• Neurological Rehabilitation
• Motor Control and Learning
• Clinical Trial Design

Background:

• Spasticity is a common motor disorder following neurological injury.
• Therapeutic stretching is a standard intervention for managing spasticity.
• Motor imagery offers a potential adjunct to physical interventions.

Purpose of the Study:

• To assess the feasibility of integrating motor imagery into therapeutic stretching routines for individuals with spasticity.
• To preliminarily evaluate the effects of motor imagery combined with stretching on spasticity parameters.

Main Methods:

• A randomized single-blind controlled pilot trial was conducted.
• Participants with arm spasticity received either motor imagery or progressive muscle relaxation during stretching.
• Key outcome measures included resistance to passive movement, passive range of motion, and the Modified Ashworth Scale.

Main Results:

• Both motor imagery and progressive muscle relaxation techniques were well-tolerated.
• No statistically significant differences were observed between the groups for primary or secondary outcome measures.
• High variability and a small sample size limited statistical power.

Conclusions:

• Motor imagery is a feasible technique to incorporate into therapeutic stretching for spasticity.
• The pilot study lacked sufficient power to demonstrate efficacy.
• Future research should involve larger sample sizes (at least 54 participants per group) to investigate motor imagery's effects on spasticity.
