Proprioceptive training to improve static and dynamic balance in elderly

Key points

1. 01Older adults aged 60 to 80 who had experienced at least one fall did a 12-week supervised proprioceptive program, twice a week, 60 minutes per session.
2. 02The trained group improved on both the Berg Balance Test (static balance) and the Four-Square Step Test (dynamic balance), with large within-group effects.
3. 03The control group, which got no treatment, showed essentially no change on either test.
4. 04Trained participants reported less fear of falling and fewer actual falls over the period than the control group.
5. 05With only 30 participants and no blinding or sham control, the findings are early and should be read with caution.

How it was conducted

Design

Randomized controlled trial with pre- and post-intervention testing over 12 weeks

Participants

30 Italian older adults, mean age 71 (SD 4.9), aged 60 to 80, 60% women, who had at least one non-debilitating fall and were mostly sedentary

Groups

Experimental group (n=15) followed a proprioceptive training protocol at a physiotherapy studio; control group (n=15) received no treatment

Intervention

Twice weekly, 60-minute sessions for 12 weeks, built around a functional circuit of balance and postural exercises repeated three times

Outcomes

Berg Balance Test for static balance, Four-Square Step Test for dynamic balance, plus a 4-item Yes/No questionnaire on confidence and fear of falling

Analysis

Independent-sample t-test, two-way repeated-measures ANOVA for intervention by time interaction, and Chi-Square for perceptions, with significance set at P < 0.05

What they found

• Experimental group Berg Balance Test rose from 39.7 (SD 7.3) pre to 46.3 (SD 7.3) post; control group went from 40.7 (SD 9.9) to 40.5 (SD 10.0).
• Experimental group Four-Square Step Test improved from 20.4 (SD 5.6) seconds pre to 15.6 (SD 4.9) seconds post; control group went from 20.1 (SD 4.6) to 19.9 (SD 4.4).
• Within the experimental group, changes were statistically significant with large effects: Berg Balance Test p=0.001, d=0.92 (0.80; 0.95) and Four-Square Step Test p=0.001, d=0.87 (0.67; 0.92).
• Within the control group, no significant change was found: Berg Balance Test p=0.695, d=0.01 (-0.02; 0.24) and Four-Square Step Test p=0.796, d=0.00 (-0.10; 0.21).
• A significant group-by-time interaction favored training: Berg Balance Test p=0.001, d=0.76 (0.58; 0.84) and Four-Square Step Test p=0.001, d=0.49 (0.20; 0.65).
• Fear of falling differed significantly between groups (X2 = 7.03; p=0.01), as did experience of falling over the last 12 weeks (X2 = 7.50; p=0.00).
• Perceptions of the importance of physical activity (X2 = 1.67; P=0.19) and of physical activity preventing falls (X2 = 2.72; P=0.10) did not differ significantly between groups.

Limitations

• The sample was very small at only 30 participants, which the authors flag as the main limitation.
• The control group received no intervention or sham, so attention and placebo effects cannot be separated from the training effect.
• The study was not blinded, and the fear-of-falling and falls outcomes relied on a brief self-reported Yes/No questionnaire.
• Follow-up ended at 12 weeks, so it is unknown whether balance gains or reduced fall fear persist over the longer term.

Why it matters

For patients

If you are an older adult who has had a fall, a supervised, several-times-weekly balance and proprioception program may help you become steadier and feel less fearful of falling.

For clinicians

Proprioceptive circuit training over 12 weeks produced large improvements in Berg Balance and Four-Square Step Test scores versus an untreated control, supporting balance training for older adults with a fall history, though small unblinded data warrant caution.

For readers

This is early, small-scale evidence that targeted balance training works, but it needs larger and better-controlled trials before the size of the benefit can be trusted.
