“…Their right ankle was dorsiflexed passively by one of the investigators until the point of reported discomfort, but not pain. The dorsiflexion ROM was measured to the nearest angle with 1° resolution using a universal inclinometer (Level Meter LM‐90, Niigata Seiki, Niigata, Japan) in a procedure similar to a previous study (Harvey et al., ). The inclinometer was aligned parallel to an imaginary line, joining the marked point of the head and base of the fifth metatarsal at the end range of passive dorsiflexion.…”

The purpose of the study was to examine the acute effect of static stretching exercise on the resting stiffness of gastrocnemius muscle belly. Ten healthy young adults performed standing wall stretching in dorsiflexion for 1 min at a time and repeated five times. Before and after stretching, the shear modulus was measured in medial and lateral heads of the resting gastrocnemius muscle with ultrasound shear-wave elastography. After the stretching, dorsiflexion range of motion (ROM) of the ankle joint increased (P < 0.01) by 3.9° and returned in 20 min. Immediately after stretching, shear modulus decreased (P < 0.01) by 14%, compared with before stretching across muscle heads. The decrease in shear modulus returned in 20 min after stretching. In the comparison group of 10 additional subjects, the standing intervention without stretching had no influence on these measures. There was a negative correlation between dorsiflexion ROM and shear modulus in either head before and after stretching. The results demonstrate the transient decreases in the stiffness of the resting gastrocnemius muscle belly and indicate that joint flexibility is greater in individuals with lower resting stiffness of the muscle belly.

“…The reliability of this procedure is high (intraclass correlation coefficient of 0.95; 95% confidence interval (CI), 0.92-0.98). 10 The secondary outcomes were spasticity in ankle plantarflexor and knee hamstring muscles and a measure of participants' perception of change. Spasticity in ankle plantarflexor and knee hamstring muscles was measured with the six-point modified Ashworth scale.…”

Study design: Assessor-blinded within-subject randomized controlled trial. Objective: To determine the effects of 6 months of regular passive movements on ankle joint mobility in people with spinal cord injury. Setting: Community, Australia. Methods: A total of 20 people with tetraplegia living in the community had one ankle randomized to a control group and the other to an experimental group. Carers administered passive movements to participants' experimental ankles for 10 min, 10 times a week for 6 months. The control ankles were left untreated. The primary outcome was passive ankle dorsiflexion range of motion. Results: Adherence was high (mean adherence rate of 96%). Ankle dorsiflexion range of motion decreased by a mean (s.d.) of 21 (4) in control ankles and increased by 21 (4) in experimental ankles. The mean (95% confidence interval, CI) effect on ankle dorsiflexion range of motion was 41 (95% CI, 2-61). Conclusion: Regular passive movements have small effects on ankle joint mobility. It is unclear if these effects are clinically worthwhile.

“…Previous methodologies have involved the use of various devices in evaluating ankle stiffness and ROM. [1][2][3] Assessment of these parameters is particularly important for orthotists to enable them to determine the mechanical properties required in an ankle-foot orthosis (AFO) design. The mechanical characteristics of AFOs and the physiological characteristics of an anatomical ankle joint need to be matched to maximize the benefit from an orthotic intervention.…”

Background and Aim: Ankle joint stiffness and its range of motion (ROM) are commonly assessed to determine the appropriate mechanical characteristics required in an effective ankle-foot orthosis (AFO) prescription. The aim of this technical note is to present the design of a manual device that enables their convenient measurement in the clinical setting and to demonstrate its reliability. Technique: The manual device was designed with a torquemeter, a potentiometer, a steering wheel, a rotary plate, and a foot plate. The measurement of resistive torque at 0° (neutral), 5° (dorsiflexion) and 10° (dorsiflexion) ankle angular positions demonstrated the high reliability of the device with Intraclass Correlation Coefficient (ICC) (1,k) values over 0.97. Discussion: Quantitative measurement of ankle joint stiffness and ROM by this manual device would provide objective information that could potentially assist AFO prescriptions. A future study should investigate how to incorporate the measurement obtained from the device into the prescription of an AFO. Clinical relevanceThe manual ankle joint assessment device enables an orthotist to assess ankle joint stiffness and ROM quantitatively and reliably in a clinical setting. The device could potentially assist AFO prescriptions when utilized in further studies.
