“…Flexible electrogoniometers are portable, which means that they can be used in confined space in clinical and occupational settings. They are also easily applicable and present high reproducibility and accuracy [4][5][6][7][8] . These motion of 30.9º ± 5.7º at natural speed on a treadmill, which was close to the value for the right ankle in the present study.…”

“…Their advantages are that they are lightweight, portable, easily applicable, do not interfere in the activities performed, do not restrict movements and adapt well to body segments 4,5 . Moreover, such equipment presents high reproducibility when utilized together with a suitable measurement protocol, with standardization of the position of the subject and the sensors 6,7 . According to Shiratsu and Coury 8 these electrogoniometers can be considered accurate, with an error of less than 5º for large movements, and minimal error in movements between 0º and 10º.…”

“…According to Shiratsu and Coury 8 these electrogoniometers can be considered accurate, with an error of less than 5º for large movements, and minimal error in movements between 0º and 10º. Although this equipment has been utilized in passive measurements of the ankle joint complex 6,7 , no studies on dynamic and functional recording of ankle movements were found in the pertinent literature. Hence, there is a need for a database of gait recordings from healthy subjects, for use in clinical settings and research.…”

Objective: To evaluate ankle movements of healthy individuals walking on a treadmill, by means of a flexible electrogoniometer. Method: Dorsiflexion and plantar flexion and eversion/inversion movements were recorded for 90 seconds at a velocity of 5.0 km/h. Ten healthy young men of mean age 21.4 ± 2.99 years and mean height 1.62 ± 0.22 meters took part in this study. The data were analyzed descriptively (mean, standard deviation, maximum and minimum). In the sagittal plane, the gait cycle was analyzed at three times, taking the movement peaks: foot flat (FF), midstance (M) and toe off (TO). The inversion and eversion angles corresponding to these phases were identified, as well as movement peaks during gait cycles. Inter and intra-subject coefficients of variability (CV) were calculated. Results: The mean values for the sagittal plane, for the left and right ankles were, respectively: 7º and 4º at FF, 2º and 7º at M, and 24º and 19º at TO. For the frontal plane, the results were inversion of 5º and 3º FF, 4º and 5º at M, and 15º and 16º at TO. The peak values were inversion of 17º and 18º and eversion of 1º. The maximum intrasubject CV was 0.39, and the maximum inter-subject CV was 0.44. Conclusion: The results obtained from the electrogoniometer were relatively similar to data reported in the literature for the sagittal plane, but not for the frontal plane. The discrepancies between studies measuring ankle movements suggest the need for standardization of the recording procedures.

“…They were based on pressure sheet and physical examination and constructed as a thin sole with delicate corrective and/or supportive elements made from leather, rubber and cork. The Dutch podiatric orthoses are different from the custom-made foot orthoses made by the Anglo-Saxon podiatrists, which are usually constructed according to the concepts formulated by Root et al[ 11 , 16 , 30 , 37 , 38 ].…”

Background: There is a need for evidence of clinical effectiveness of foot orthosis therapy. This study evaluated the effect of foot orthoses made by ten podiatrists, ten pedorthists and eleven orthotists on plantar pressure and walking convenience for three patients with metatarsalgia. Aims were to assess differences and variability between and within the disciplines. The relationship between the importance of pressure reduction and the effect on peak pressure was also evaluated.

“…Test angles near to maximum ROM (i.e., 90%IN/EV) are defined as extreme test angles and are considered a limitation due to the effect of additional sensory input from cutaneous receptors on the ability to reproduce the test angle (Burke et al, 1988). The average IN/EV ROM has been identified as 30 and 18 • , respectively (Ball and Johnson, 1996). In our study, we employed test angles of IN60% and IN/EV30% of each participants ROM, which corresponds to an ∼18 • IN and 9 • EV test angle based on the average IN/EV ROM.…”

Impaired proprioceptive acuity negatively affects both joint position sense and postural control and is a risk factor for lower-extremity musculoskeletal injury in athletes and military personnel. British Army foot-drill is an occupational military activity involving cyclical high impact loading forces greater than those observed in athletes during high level plyometrics. Foot-drill may contribute to the high rates of lower-extremity overuse injuries observed in recruits during basic training. There is limited research investigating foot-drill specific injury risk factors in women, despite greater incidences of musculoskeletal injury reported in women (522 vs. 417 per 1,000 personnel, OR: 1.53) when compared to men during basic training. This study aimed to quantify changes in ankle joint proprioception and dynamic postural stability following a period of British Army foot-drill. Fourteen women of similar age to British Army female recruits underwent pre-post foot-drill measures of frontal plane ankle joint position sense (JPS) and dynamic postural stability using the dynamic postural stability index (DPSI). Passive ankle JPS was assessed from relative test angles of inversion 30% (IN30%) and eversion 30% (EV30%) and IN60% of participants range of motion using an isokinetic dynamometer. The DPSI and the individual stability indices (medio-lateral [MLSI], anterior-posterior [APSI], and vertical [VSI]) were calculated from lateral and forward jump-landing conditions using force plates. Foot-drill was conducted by a serving British Army drill instructor. Significantly greater absolute mean JPS error for IN30% and EV30% was observed post foot-drill (p ≤ 0.016, d ≥ 0.70). For both the lateral and forward jump-landing conditions, significantly greater stability index scores were observed for MLSI, APSI, and DPSI (p ≤ 0.017, d ≥ 0.52). Significantly greater JPS error and stability index scores are associated with the demands of British Army foot-drill. These results provide evidence that foot-drill negatively affects lower-extremity proprioceptive acuity in recruit age-matched women, which has implications for increased injury risk during subsequent military physical activity, occurring in a normal training cycle.
