Better Essays

I. Introduction a. Topic- Falls are a common and serious problem in older individuals with or without neurological condition (Pai, Bhatt, Yang & Wang, 2014). b. Fall Incidence- Over 18,000 elderly individuals died from falling in 2007 and 2.2 million elderly individuals visited emergency departments for debilitating nonfatal injuries related to fall in 2009 (Liu and Kim, 2012). c. Impacts on Individuals- Falls can result in debilitating injuries, fractures, physical disabilities, loss of independence, transfer to an institution and also death. About 60% of perturbation related outdoor falls in community dwelling older adults over 70 years of age are due to slips or trips (Liu and Kim, 2012; Pai, Bhatt, Yang, et al., 2014). d.

Study elements which are questionable a. Sample and Setting i. The sample size was usually small, ranging from (n= 5-32) for almost all the studies (Pai, Wang, Espy, et al, 2010; Liu and Kim, 2012; Shimada, et al, 2004; Pai, Bhatt, Yang, et al., 2014; Mansfield, et al, 2010). However, one study had a large small size (n=212) but, More than 80% of this larger sample size could not complete the training program due to drop out rates. Therefore, the results of all the studies were drawn from smaller sample size (Pai, Bhatt, Yang, et al., 2014). All these sample size questions the generalizability of the study (bad external validity). ii. All the studies were carried out in the laboratory and long term care clinic setting. None of the studies were performed which could mimic home setting or community setting. (Pai, Wang, Espy, et al, 2010; Liu and Kim, 2012; Shimada, et al, 2004; Pai, Bhatt, Yang, et al., 2014; Mansfield, et al, 2010). iii. Only female samples were chosen in the study by Liu and Kim, (2012), which results into gender bias. It also questions the external …show more content…

Although, the results of the study can generalize to similar population, the further research should be done with larger samples and setting other than laboratory. b. Limitations of the study i. The participants were not blinded in the study by Shimada, et al, (2004), which questioned internal validity. Although, fall rates were reduced in the training group, there is need of a further study which was performed with blinding of the participants. ii. Since, computer programs and new assessment tools like treadmills with cables or harness were used, those researches were not cost effective. Therefore, it will be difficult to perform those interventions in real life setting (Pai, Wang, Espy, et al, 2010; Liu and Kim, 2012; Shimada, et al, 2004; Pai, Bhatt, Yang, et al., 2014; Mansfield, et al, 2010). iii. All the participants chosen for the study were healthy older adults which do not mimic the real life patients which questions the external validity. These healthy older population, presumably are more likely to have the neuromotor plasticity and to respond safely and develop subsequent fall response strategies than the more impaired older adults (Pai, Bhatt, Yang, et al.,
