Washington: It`s long been known thatlistening to music can ease stress, now a new research claimsthat it has a powerful effect on brain and may help improvemovement in stroke patients. The research, which is a review of several studies onthe benefits of music therapy, found that music appears tohave beneficial effects on stroke patients and can help themimprove their movement. More than 20 million people suffer strokes each year.Many patients acquire brain injuries that affect theirmovement and language abilities, which results in significantloss of quality of life.
In one trial, RAS also improved arm movements, asmeasured by elbow extension angle. "This review shows encouraging results for the effectsof music therapy in stroke patients," said lead researcherJoke Bradt of the Arts and Quality of Life Research Center atTemple University in Philadelphia, US. "As most of the studies we looked at used rhythm-basedmethods, we suggest that rhythm may be a primary factor inmusic therapy approaches to treating stroke." Other music therapy techniques, including listening tolive and recorded music, were employed to try to improvespeech, behaviour and pain in patients with brain injuries,and although outcomes in some cases were positive, evidencewas limited. "Several trials that we identified had less than 20participants," said Bradt. "It is expected that larger samples sizes will be usedin future studies to enable sound recommendations for clinicalpractice." A systematic review is a summary of research that usesexplicit methods to analyse individual studies to identify thevalid and applicable evidence. Many health care journals publish systematic reviews,but the best-known source is the Cochrane Collaboration whichhas over 15,000 specialists to analyse individual studies. PTI
