- Brief Summary
The main objective of the study is to assess the feasibility of a randomized clinical trial that investigates the effects of an 8-week group exercise program on pain, disability, fear of falling, overall impression of recovery, frequency of falls and level of physical activity in elderly people with nonspecific low back pain.
- Detailed Description
The main objective of the study is to assess the feasibility of a randomized clinical trial that investigates the effects of an 8-week group exercise program on pain, disability, fear of falling, overall impression of recovery, frequency of falls and level of physical activity in elderly people with nonspecific low back pain. The evaluation of feasibility will be related to: (1) blinding the evaluator to allocate the groups; (2) eligibility and recruitment rates; (3) acceptability of random allocation to a group; (4) possible contamination between groups; (5) adherence to treatment; (6) satisfaction with the treatment; and (7) difficulty in understanding the information provided by the physiotherapist.

Group Intervention Description Group-Based Exercise Group-Based Exercise The group-based exercise (GBE) programme will be delivered by a physiotherapist. The GBE comprises three sessions per week of group-based exercise in a local community centre, for 8 weeks.
- Primary Outcome Measures
Name Time Method Feasibility of blinding the assessor 8 weeks from randomization Feasibility of blinding will be assessed by asking the assessor two questions at the end of the follow-up assessment:
1. Did you receive any information that indicated to you which group the participant was assigned to?
2. How did you receive information about group assignment?
Assessor's guess regarding group assignment group will be recorded for each participant.
The responses will be coded as correct or incorrect guess.
The frequency and relative rates of 'Yes' and 'No' as the answer to the first question will be computed, as will the frequency and relative rates of correct and incorrect guesses. Finally, reasons for guesses will be recorded as verbatim and reported.Difficulty in understanding the information provided by the physiotherapist 8 weeks from randomization Difficulty in understanding the information provided by the physiotherapist measured on a five-point categorical scale: Very easy, Easy, Neither easy nor difficult, Difficult, Very difficult
Eligibility and recruitment rates 8 weeks from randomization Eligibility and recruitment rates
Acceptability of random allocation to a treatment group 8 weeks from randomization Outcome assessor will ask the participants if random allocation to one of the two treatment groups is acceptable to the participants. Responses will be recorded as 'Acceptable', 'Not acceptable' or 'No preference'.
The frequencies of each response will be computed separately for each treatment condition.Understanding possible contamination between the groups 8 weeks from randomization Measures to assess:
Have you talked to other participants in this study about the intervention they are receiving? Has your attitude towards the intervention changed after talking to the participant (s) in the other group? Are any of the participants in the other group aware of the type of intervention you are receiving in this study?
The frequencies of the participants who responded affirmatively to each question will be computed separately for each treatment condition.Adherence to treatment 8 weeks from randomization Adherence to treatment measured by frequency during the intervention
Satisfaction with the treatment 8 weeks from randomization All the participants of the intervention group will be asked to respond an adapted version of the MedRisk Instrument for Measuring Patient Satisfaction With Physical Therapy Care at 1 week following treatment. The question asked will be:
1. Did my physiotherapist carefully explain the treatments I received?
2. Did my physiotherapist treat me respectfully?
3. Did my physiotherapist answer all my questions? n general, am I completely satisfied with the services I received from my physical therapist? Responses to this question are made on a five-point categorical scale 1='completely disagree'; 2='Disagree'; 3= 'Neutral'; 4=' Agree'; 5=' Completely agree').
The frequency of response for each question will be analyzed
- Secondary Outcome Measures
Name Time Method Global perception of recovery 8 weeks from randomization Global perception of recovery measured with Global Effect Perception Scale. This is a numerical scale where -3 represents "worse than ever", 0 "without modification" and 3 "completely recovered". A higher score means greater recovery from the condition.
Level of physical activity 8 weeks from randomization Level of physical activity measured with the Physical Activity Rating scale. It is a progressive scale with scores from 0 to 7, in which the most appropriate option for the history of physical activity practice in the last 30 days should be selected.
Frequency of falls 8 weeks from randomization Frequency of falls assessed by the number of falls during the study period
Pain intensity 8 weeks from randomization Pain intensity measured with a Numerical Rating Scale from 0 to 10, , where 0 does not cause pain and 10 is the worst pain imaginable.
Disability 8 weeks from randomization Disability measured with the Roland-Morris Disability Questionnaire. The questionnaire has 24 items with scores of 0 or 1 (yes or no) and the total ranges from zero (suggesting no disability) to 24 (severe disability).
Fear of falling 8 weeks from randomization Fear of falling measured with the Falls Efficacy Scale- International. The Falls Efficacy Scale - International presents questions about the concern with the possibility of falling when performing 16 activities, with respective scores from one to four. The total score can range from 16 (no concern) to 64 (extreme concern).
