Assignment 2: Health Psychology

The basis of this assignment revolves around the following proposition: “An exercise/physical
activity intervention can positively influence cognitive function in patients with Alzheimer’s
disease”. My chosen article is titled Exercise Program for Nursing Home Residents with
Alzheimer's Disease: A 1-Year Randomized, Controlled Trial by Yves Rolland et al.
What was the rationale for doing this study? The rationale for conducting this study was
to determine if patients with Alzheimer’s disease could see improvement in their activities of
daily living from a regularly implemented exercise routine over the course of twelve months.
Briefly explain the design of the study. This was a controlled and randomized single-blind
study consisting of similar groups of mobile patients living with Alzheimer’s disease across five
different nursing homes. Individual subjects as opposed to the nursing homes themselves were
randomized to the two groups in order to avoid the confounding effects of the setting area. One
geriatrician who was blinded to the intervention assignment measured outcomes at baseline,
midway though, and at the end of the study on days where no intervention was carried out.
In order to be eligible to participate in the study, patients had to meet the National
Institute of Neurological and Communicative Diseases and Stroke/Alzheimer Disease and
Related Disorders Association criteria for probable or possible AD, had to have lived in the
nursing home for at least two months, and had to be able to transfer from a chair and walk at
least six meters without human assistance (Rolland, 2007). Once eligible subjects were identified
and consent was gathered, subjects were then assigned to either the control group (routine
medical care, 67 participants) or the experimental group (12-month exercise program, 67
participants) by a lottery draw carried out by staff not involved in either intervention or
Briefly Describe the interventions used. In this study, the intervention used was an exercise
program focusing primarily on aerobic, balance, strength and balance training conducted in
groups of 2-7 subjects. Patients were assigned to groups based on their baseline physical
performance scores, a mental state examination and their interpersonal relationships with each
other. The program was carried out by the same occupational therapist over the course of 12
months, and consisted of 1 hour sessions in the afternoon twice a week for a total of 88 sessions
During each session, a circular “walking trail” established specifically for this study was
utilized in each nursing home. Participants were encouraged to walk to the point of
breathlessness (but not exhaustion) for at least half the session, while stopping at stations relating
either to strength, flexibility or balance. Strength stations were adapted to each participant and
focused on the lower extremities. Dynamic movements such as squatting, repeated stand ups
from a chair, lateral elevation of the legs from a standing position and toe rises were performed.
In the flexibility stations, participants were asked to imitate the occupational therapist
performing simple (no examples were given) flexibility exercises. Balance stations utilized cones
and hoops on the ground for small step trial exercises, as well as foam-rubber ground sheets for
patients to perform one or two-legged balance exercises.
