Bernier & Perrin, 1998 [20] | 48 males & females with FAI | Not specified | Control group (n = 14) - no intervention Sham electrical stimulation group (n = 14) Training group (n = 17) - static & dynamic balance training 3 times a week × 6 weeks | SI & MES in SLS for 4 conditions: stable platform with eyes open and eyes closed, and dynamic platform with eyes open and eyes closed Active and passive JPS data for 7 positions: 15° inversion, 0° degrees neutral, and 10° of eversion, performed at 0° and 25° of plantarflexion. Maximum inversion in 25° plantarflexion was also assessed | Training group showed significant MES improvements over the other 2 groups in AP & ML directions for the stable platform and dynamic platform conditions respectively with eyes closed Significant within training group improvements were also noted in the A/P and M/L directions for both conditions with eyes closed | MES - stable platform, eyes closed: A/P direction: 1.08; 95% CI (10.52-30.48) M/L direction: 1.09; 95% CI (5.28-25.72) MES - dynamic platform, eyes closed: A/P direction: 0.71; 95% CI (68.27-78.73) M/L direction: 0.958; 95% CI (65.25-74.75) | MES - stable platform, eyes closed: A/P direction: 0.99 95% CI (12.13-31.87) M/L direction: 0.92; 95% CI (12.63-33.37) MES - dynamic platform, eyes closed: A/P direction: 0.52; 95% CI (63.9-81.10) M/L direction: 0.55; 95% CI (60.9-78.1) |
Docherty et al, 1998 [29] | 20 healthy college students (10 males, 10 females) with FAI | Not specified | Training group (n = 10) -T-band strengthening 3 times a week × 6 weeks Control group (n = 10) - no intervention | Dorsiflexor and evertor isometric muscle strengths Active JPS data collected at 20° for inversion & plantarflexion, & at 10° for eversion and dorsiflexion | Significant beween group interactions for dorisflexion and eversion strength, and inversion, and plantarflexion JPS Significant improvements in all strength and JPS measures post-test within the training group | Dorsiflexion strength: 2.99; 95% CI (38.51-45.39) Eversion strength: 0.83; 95% CI (34.42-41.48) Inversion JPS: 0.98; 95% CI (2.38-7.22) Eversion JPS: 0.77; 95% CI (1.55-5.15) Dorsiflexion JPS: 0.85; 95% CI (1.56-4.54) Plantarflexion JPS: 1.51; 95% CI (2.51-6.79) | Dorsiflexion strength: 2.93; 95% CI (39.31-45.19) Eversion strength: 1.94; 95% CI (27.77-44.93) Inversion JPS: 1.32; 95% CI (2.92-6.28) Plantarflexion JPS: 1.56; 95% CI (2.06-4.84) |
