Table 4 Efficacy of vibration therapy on spasticity

Ref.	Prescription	Evaluation method	Curative effect
Bao et al[54]	The frequency was 36.7 Hz, and the total duration of treatment was 10 min, once/d, 5 times/wk for 3 consecutive wk	b, c, d	Effectively reduced the spasm muscle tension, improved its elasticity and hardness, improved limb movement function
Yin et al[55]	Frequency 12 Hz, amplitude 4 mm, each lasting 15 min, 5 times/wk for 12 wk	e, f, g	Effectively improved ankle motion, balance function and lower limb movement ability in children with spastic diplegia
Li et al[56]	Frequency 30 Hz, 0.5 mm amplitude once/d 2 min each time and 2 min rest interval. Four-week treatment course with a total of two courses	a, d, h, i	Reduced ankle plantar flexor spasm, improved walking ability, and improved activities of daily living
Katusic et al[57]	Frequency 40 Hz, 20 min each time, twice/wk for 12 wk	a, j	Reduced the level of spasticity and improved the gross motor capacity in children with spastic cerebral palsy
Cai et al[58]	Treatment frequency: First 12 Hz, second 18 Hz, and third 21 Hz. 3 min/time for 9 min, training for 5 d/wk and 2 d rest for 8 wk	f, j	Effectively reduced muscle tension, improved muscle strength, abnormal posture and postural control ability in spastic cerebral paralysis

a: Modified Ashworth scale; b: Modified Tardieu scale; c: Myoton-3 muscle state detector assessment; d: Fugl-Meyer motor function rating scale; e: Scale of ankle dorsiflexion; f: Berg, balance scale; g: Gross motor function for cerebral palsy; h: Gait analysis; i: Modified Barthel index scale; j: Gross motor function (GMFM-88).
