Background: Clinical measurement of passive dorsiflexion of the ankle joint is essential for the diagnosis of various pathologic conditions of the foot and ankle but is of unreliable precision with high interobserver variability in nonweightbearing tests. This work was designed to develop and test a precise, standardized, and reliable technique for measurement of passive and active ankle range of motion. Methods: The proposed measurement tool is composed of two mobile parallelograms, one attached to the tibia, the second one to the plantar surface of the foot. The parallelograms are connected with a hinge with an angular scale to measure the angle between the foot and tibia. Results: Interobserver correlation between clinical measure-ments for maximal passive foot dorsiflexion were 0.03 with knee extension and 0.38 with knee flexion, while for measurements with the proposed tool they reached 0.89 and 0.97, respectively, with a mean measurement error of 0.9 degrees. Intraobserver correlations reached values of r = 0.98 and 0.99. Conclusions: The proposed tool allows measurement of the ankle range of motion with very high precision and reproducibility far superior to clinical measurements. Clinical Relevance: Precise measurement of ankle range of motion is clinically challenging. With the use of the proposed tool, measurement precision and reliability are decisively improved.

The purpose was to determine if smartphone photography is a reliable tool in measuring wrist movement. Smartphones were used to take digital photos of both wrists in 32 normal participants (64 wrists) at extremes of wrist motion. The smartphone measurements were compared with clinical goniometry measurements. There was a very high correlation between the clinical goniometry and smartphone measurements, as the concordance coefficients were high for radial deviation, ulnar deviation, wrist extension and wrist flexion. The Pearson coefficients also demonstrated the high precision of the smartphone measurements. The Bland–Altman plots demonstrated 29–31 of 32 smartphone measurements were within the 95% confidence interval of the clinical measurements for all positions of the wrists. There was high reliability between the photography taken by the volunteer and researcher, as well as high inter-observer reliability. Smartphone digital photography is a reliable and accurate tool for measuring wrist range of motion. Level of evidence: II

Background The definition of equinus varies from less than 0° to less than 25° of dorsiflexion with the foot at 90° to the leg. Despite its pervasive nature and broad association with many lower-extremity conditions, the prevalence of ankle equinus is unclear. Furthermore, there are few data to suggest whether equinus is predominantly a bilateral finding or isolated to the affected limb only. Methods We conducted a prospective cohort study examining consecutive patients attending a single foot and ankle specialty practice. Participation involved an assessment of ankle joint range of motion by a single rater with more than 25 years of clinical experience. We defined ankle equinus as ankle joint dorsiflexion range of motion less than or equal to 0° and severe equinus as less than or equal to –5°. Patients who had previously experienced an Achilles tendon rupture, undergone posterior group lengthening (ie, Achilles tendon or gastrocnemius muscle lengthening), or had conservative or surgical treatment of equinus previously were excluded. Results Of 249 included patients, 61% were female and 79% nondiabetic. The prevalence of ankle equinus was 73% [183 of 249], and nearly all of these patients had bilateral restriction of ankle joint range of motion (prevalence of bilateral ankle equinus was 98.4% [180 of 183] among those with equinus). We also found that ankle equinus was more common in patients with diabetes, higher body mass indexes (BMIs), or overuse symptoms. Conclusions The prevalence of ankle equinus in this sample was higher than previously reported, and nearly all of these patients had bilateral involvement. These data suggest that many people attending foot/ankle specialty clinics will have ankle equinus, and select groups (diabetes, increased BMI, overuse symptoms) are increasingly likely.

Flat foot is the most common foot disorder that influences the alignment of the lower limb structure. It is controversial whether the use of foot insole influences kinetic and kinematic of the leg or not. Therefore, this study investigated the influence of foot insole on the gait performance in subjects with flat foot disorder. A group of flat foot subject was recruited into this study (the number of subjects was 15). The motion of the leg joints was determined using the Qualysis motion analysis system. Moreover, the force applied on the lower limb was recorded by a Kistler force plate. The range of motion of the lower limb joints, the moments applied on the lower limb joints and force transmitted through the leg were the parameters used in this study. The difference between these parameters during walking with and without insole was evaluated using the paired [Formula: see text]-test. Significant value was set at [Formula: see text]. There was no significant difference between the range of motion of ankle joint while walking with and without insole. However, the medial directed force applied on the leg decreased significantly [Formula: see text]. The use of foot insole did not influence the moments transmitted through the hip and knee joints. The walking speed of the subjects improved while walking with foot insole. Use of foot insole influenced the magnitude of the force applied on the leg and the adductor moment of ankle joint due to its influence on foot alignment. As the walking speed of the improved subjects follows the use of insole, it can be concluded that it may have a positive effects on the performance of flat foot subjects.

Abstract The aim of this study is to evaluate the results of patients underwent lateral open wedge calcaneus osteotomy with bony allograft augmentation combined with tibialis posterior and tibialis anterior tenodesis. Twenty-two patients underwent adult-acquired flatfoot deformity were retrospectively evaluated with a minimum 2-year follow-up. Radiographic preoperative and final comparison of tibio-calcaneal angle, talo–first metatarsal and calcaneal pitch angles have been performed. The Visual Analog Scale, American Orthopedic Foot and Ankle Score, the Foot and Ankle Disability Index and the Foot and Ankle Ability Measure were used for subjective and functional assessment. The instrumental range of motion has been also assessed at latest follow-up evaluation and compared with preoperative value. There was a significant improvement of final mean values of clinical scores (p < 0.001). Nineteen out of 22 (86.4%) patients resulted very satisfied or satisfied for the clinical result. There was a significant improvement of the radiographic parameters (p < 0.001). There were no differences between preoperative and final values of range of motion. One failure occurred 7 years after surgery. Adult-acquired flatfoot deformity correction demonstrated good mid-term results and low recurrence and complications rate. Level of evidence Level 4, retrospective case series.

This study aimed to investigate the effects of suboccipital muscle inhibition technique (SMIT) on active range of motion (AROM) of the ankle joint, lunge angle (LA), and balance in healthy adults, according to the duration of its application. A total of 80 participants were randomly allocated to the 4-min suboccipital muscle inhibition (SMI) group (SMI_4M, n = 20), 8-min SMI group (n = 20), 4-min sham-SMI (SSMI) group (n = 20), and 8-min SSMI group (n = 20). Accordingly, the SMIT and sham SMIT were applied for 4 min or 8 min in the respective groups. AROM of dorsiflexion and LA were assessed, and a single leg balance test (SLBT) was performed before and after the intervention. AROM (4 min, p < 0.001; 8 min, p < 0.001), LA (4 min, p < 0.001; 8 min, p < 0.001), and SLBT (4 min, p < 0.001; 8 min, p < 0.001) significantly improved after SMI application. Compared with the SSMI group, the SMI group showed a significant increase in AROM (p < 0.001), LA (p < 0.001), and SLBT (p < 0.001). Except for SLBT (p = 0.016), there were no significant interactions between intervention and application duration. The results suggest that the SMIT, at durations of both 4 and 8 min, could be effective tools for improving AROM, LA, and balance.

Category: Hindfoot Introduction/Purpose: Objective: To evaluate and quantify the loss of ankle mobility in patients undergoing subtalar arthrodesis compared to the contralateral side, through physical examination. Methods: A total of 12 patients who had only the subtalar arthrodesis procedure from various causes in one foot were selected. The same foot and ankle surgeon performed all measurements of bilateral tibiotarsal range of motion, with loaded closed-chain and unloaded open-chain tests. Then, to assess whether there was a difference between the operated and the non-operated side, statistical analysis was performed with the Mann-Whitney test (Hollander and Wolfe 1999). Results: On the loaded closed-chain test, the operated side had a significantly lower range of motion than the contralateral side, with a mean difference of 5.4 degrees for dorsal flexion and 7.6 degrees for plantar flexion. The open-chain tests showed non- significant differences of 3 degrees for dorsal flexion and 5.3 degrees for plantar flexion. Conclusion: Subtalar joint arthrodesis was shown to cause a loss of mobility in the ipsilateral ankle, which is greater in plantar flexion movement.

The ability to accurately measure three dimensional (3D) bone kinematics is key to understanding the motion of the joints of the body, and how such motion is altered by injury, disease, and treatment. Precise measurement of such kinematics is technically challenging. Biplane fluoroscopy is ideally suited to measure bone motion. Such systems have been developed in the past for both radiographic stereo-photogrammetric analysis (RSA) [1] and the more challenging model-based analysis [2]. Research groups have studied the knee [3,4], shoulder [5] and ankle [6] motion with similar techniques. The work presented here is an initial evaluation of the performance of our system, i.e., a validation that this in-house system can detect magnitudes of motion on-par with other existing systems.

AbstractThe purpose of this study was to investigate whether patients can accurately self-assess their knee passive range of motion (PROM). A picture-based questionnaire for patient self-assessment of knee PROM was developed and posted to patients. The self-assessed PROM from 58 patients was compared with surgeon-assessed PROM using a short-arm goniometer. Agreement between the measurement methods was calculated with the Bland-Altman method. We calculated the sensitivity and specificity of patient-assessed PROM in dichotomously detecting knee motion impairment in both flexion (≤ 100 degrees) and extension (≥ 10-degree flexion contracture). Surgeon- and patient-assessed knee PROM showed a mean difference (95% limits of agreement) of −2.1 degrees (−42.5 to 38.3 degrees) for flexion and −8.1 degrees (−28.8 to 12.7 degrees) for extension. The sensitivity of patient self-assessed PROM in identifying knee flexion and extension impairments was 86 and 100%, respectively, whereas its specificity was 84 and 43%, respectively. Although wide limits of agreement were observed between surgeon- and patient-assessed knee PROM, the picture-based questionnaire for patient assessment of knee ROM was found to be a valid tool for dichotomously detecting knee motion impairment in flexion (≤ 100 degrees). However, the specificity of the questionnaire for detection of knee extension impairments (≥ 10-degree flexion contracture) was low, which limits is practical utility for this purpose.
