HHD measurements depend on operator\u2019s ability and joint movements. The aim of the work is to validate the use of a commercial HHD in both dorsiflexion and plantarflexion ankle strength measurements quantifying the effects of HHD misplacements and unwanted foot\u2019s movements on the measurements. We used an optoelectronic system and a multicomponent load cell to quantify the sources of error in the manual assessment of the ankle strength due to both the operator\u2019s ability to hold still the HHD and the transversal components of the exerted force that are usually neglected in clinical routine. Results showed that foot\u2019s movements and angular misplacements of HHD on sagittal and horizontal planes were relevant sources of inaccuracy on the strength assessment. Moreover, ankle dorsiflexion and plantarflexion force measurements presented an inaccuracy less than 2% and higher than 10%, respectively. In conclusion, the manual use of a uniaxial HHD is not recommended for the assessment of ankle plantarflexion strength; on the contrary, it can be allowed asking the operator to pay strong attention to the HHD positioning in ankle dorsiflexion strength measurements.<\/jats:p>","DOI":"10.1155\/2017\/5426031","type":"journal-article","created":{"date-parts":[[2017,7,27]],"date-time":"2017-07-27T17:04:04Z","timestamp":1501175044000},"page":"1-8","source":"Crossref","is-referenced-by-count":11,"title":["Validation
