Abstract
The aim of this study was to evaluate the effects of motor imagery and action observation combined with a hand grip strength program on the forearm muscles. Sixty subjects were selected and randomized into three groups: motor imagery (nâ¯=â¯20), action observation (nâ¯=â¯20), or a control group (nâ¯=â¯20). Outcome measures included hand grip strength, electromyographical activity and intramuscular oxygenation. The hand grip strength significantly increased in the motor imagery (pâ¯<â¯.001) and action observation (pâ¯<â¯.001) groups compared with the control group, although there were no differences between the both groups (pâ¯=â¯.30). In the electromyographical activity, intra-group significant differences were found in motor imagery (pâ¯=â¯.002) and action observation (pâ¯=â¯.003) groups, although there were no differences between the both groups (pâ¯=â¯1.00) Intramuscular oxygenation results did not show any statistically significant differences between any of the study groups (pâ¯>â¯.05). Our results suggest that both motor imagery and action observation training, combined with a hand grip strength program, present a significant strength gain and significant change in the strength and electromyographical activity of the forearm muscles, however no change was found in intramuscular oxygenation.
