We first provide an overview of the conclusions of the systematic reviews found in our search. Next, for each positive trial we describe the following elements of the exercise component of the intervention: frequency, time of sessions, length of program, intensity, type of exercise including a description of the specific exercises performed, whether the intervention was delivered in a group or on an individual basis, the professional delivering the intervention, and any other features of the intervention aside from the exercise component. We used the ProFaNE taxonomy definitions [25] to identify and describe each element of the exercise interventions. Frequency is the number of times per week that residents engage in sessions, time of sessions is the amount allocated to each exercise session, duration of program is how long the resident participates in the exercise program, and intensity is the subjective or objective report of how hard the resident is working [25]. The types of exercises described were those targeting balance defined as “...the efficient transfer of bodyweight from one part of the body to another or challenges specific aspects of the balance systems (eg, vestibular system)” [25], and strength defined as “...contracting the muscles against a resistance to ‘overload’ and bring about a training effect in the muscular system” [25]. Strength could be either an external resistance (eg, dumbbell) or using body weight against gravity (eg, squat) [25].
Results
We found 3 systematic reviews that include exercise programs to reduce falls in LTC homes [17,19,20]. Overall, evidence suggests that exercise should be included as part of a multifactorial falls prevention program for residents in LTC. There is limited evidence that exercise as a single intervention prevents falls, and some trials, albeit underpowered, even demonstrate an increased risk of falling in the exercise group compared to control [19]. With regards to specific exercise programs, the Cochrane review found that gait, balance, and functional training decrease the rate of falls but not the risk of falling [26–28], and the 2013 review by Silva et al [20] concluded that combined exercise programs (ie, multiple types of exercise) that include balance tasks, are completed frequently (2–3 times per week), and over a long term (greater than 6 months) were most effective at preventing falls [20].
A more recent systematic review and meta-analysis [17] also concluded that there was no evidence that exercise as a single intervention can prevent falls for residents in LTC. Table 1 provides a description of the exercise component of the seven positive trials [29–35] that were included in the 3 systematic reviews we identified in our search.
Type of Exercise
Balance Exercises
There were 4 positive trials that included balance exercises in their intervention [31,33–35]. Trials that had a positive effect on reducing falls and included balance training employed mostly dynamic balance exercises in standing (Table 1). However, only 2 of the 7 trials provided a detailed description of their balance exercises (Table 1) [26,34]. Jensen et al [30] and Dyer et al [31] did not include a description of the balance training performed but stated that balance was part of the multicomponent exercise program. Becker et al [36] stated that participants performed standing balance exercises, while Schnelle et al [39] and Huang et al [32] did not include balance training in their trial.
Strength Exercises
Of the 7 positive trials included in this review, 6 included strength exercises [29–32,34,35]. The strength activities used in trials where exercise had a positive effect on decreasing falls included functional activities [29,31] and progressive resistance training [31,36] (Table 1). Functional activities are those that replicate what a resident might be required to do in their everyday life, such as performing sit-to-stands out of a chair (Figure)
or practicing bed mobility (eg, rolling from side to side, transitioning from lying to sitting and vice versa) [25]. The exercise program in Schnelle et al’s [29] trial had residents performing sit-to-stands every 2 hours, and arm curls or arm raises once a day. Participants in Jensen et al [30] at Dyer et al’s [31] trials performed progressive resistance training but did not describe which particular exercises participants performed. Similarly, Becker et al [36] described progressive resistance training with dumbbells and ankle weights but did not describe any specific exercises. Participants in the trial by Lord et al [34] performed strengthening exercises of ankle dorsiflexors, knee extensors, hip abductors, and hip side flexors. One trial stated their exercise program focused on muscle endurance rather than strength (eg, higher repetitions with lower resistance), and participants did grip ball exercises, ankle dorsiflexion and plantar flexion, upper limb elevation, knee elevation, and sit-to-stands [32].
