“…experiment. Data used in this analysis are those from a previous work from the authors 20 , where the hand kinematics of twenty-four right-handed adults were obtained while performing a representative set of ADL (Table 1) for the purpose of computing functional ranges of motion. The experiment performed to obtain these recordings is briefly explained next.…”

“…The way of applying this scaling is by subtracting the mean and dividing by the SD as it is commonly done in normal standardization, but instead of using mean and SD from the sample, mean and SD used are those from Table 2. In a previous work 20 , the authors recorded static postures to obtain the maximal active ranges of motion of each joint in a sample of healthy subjects, and these extreme values were averaged across subjects. Mean and SD taken from these extreme postures are reflected in Table 2.…”

“…Then, synergies of each cluster were averaged to obtain the CSs. To graphically represent the CSs with Opensim, we constructed hand postures by adding the CS scaled by a constant factor to the mean conformation, the factor acting to constrain the range of motion within biologically feasible limits according to 20 .

“…Therefore, considering all the aforementioned, and with the aim of substantiating the existence of sparse grasping synergies, we propose the look for the set of sparse synergies shared across subjects by: (i) applying PCA per subject, with the new scaling method proposed and applying Varimax rotation, to the kinematics recordings of a previous work 20 , where a sample of healthy subjects performed a wide set of real activities of daily living (ADL) representative of healthy hand function 3 ; and (ii) checking for similitudes across comparable subject-specific synergies obtained, in order to detect whether subjects perform ADL by using similar synergies, what those synergies are, and their frequency of use by the subjects. Additionally, we have investigated whether merged unreal synergies appear if PCA is applied to data from several subjects altogether.…”

Roda-Sales the motor system is hypothesised to use kinematic synergies to simplify hand control. Recent studies suggest that there is a large set of synergies, sparse in degrees of freedom, shared across subjects, so that each subject performs each action with a sparse combination of synergies. identifying how synergies are shared across subjects can help in prostheses design, in clinical decision-making or in rehabilitation. Subject-specific synergies of healthy subjects performing a wide number of representative daily living activities were obtained through principal component analysis. to make synergies comparable between subjects and tasks, the hand kinematics data were scaled using normative range of motion data. to obtain synergies sparse in degrees of freedom a rotation method that maximizes the sum of the variances of the squared loadings was applied. Resulting synergies were clustered and each cluster was characterized by a core synergy and different indexes (prevalence, relevance for function and within-cluster synergy similarity), substantiating the sparsity of synergies. The first two core synergies represent finger flexion and were present in all subjects. The remaining core synergies represent coordination of the thumb joints, thumb-index joints, palmar arching or fingers adduction, and were employed by subjects in different combinations, thus revealing different subjectspecific strategies.

Introduction: This review article is the product of research on the methods, techniques and devices used in the measurement of fine motor skills of upper limbs and its respective evolution, developed at Universidad del Cauca in 2018. Problem: Objective measurement of the evolution of upper limb motor skills in the rehabilitation processes. Objective: To identify the conventional techniques and electronic devices used in the measurement of the evolution of upper limb motor ability. Methodology: Four scientific databases were reviewed in addition to the Google Scholar search engine. The keywords used for the search were: "fine motor skills", "hand measurement", "hand rehabilitation"and "hand function", among others. Results: Approximately 3840 articles related to the subject were found. When applying the exclusion criteria, the article number to be revised was reduced to 63, which were analyzed in the present review. Conclusions: The tools applied by health professionals are convenient due to their rapid execution and easy access, however they can be subject to human error since they depend on the experience of the user. Electronic systems present objective measurements, however, their complexity and cost are high. Originality: This work presents information on the therapeutic techniques and technological devices used, in certain pathologies, for the evaluation of upper limb motor ability. Limitations: Not all articles analyzed have a detailed description of the people in which the studies were conducted.

Evaluation of surgical effects is often done using simple cadaver experimentation. This study uses a robotic testbed to estimate the best‐case clinical outcomes of flexor tendon shortening during repair surgery on cadaver hands. Nine fresh‐frozen cadaver subjects were connected to an extrinsic index finger robotic muscle testbed and measurement system. The flexor digitorum profundus tendons were severed and surgically repaired at different shortening levels. The index finger's extrinsic tendons were robotically actuated using Hill‐type muscle models to emulate the muscle force‐length relationships. Extensor muscles were then activated to estimate the active range of motion (ROM) of the all‐finger joints after surgery. The effects of metacarpophalangeal (MCP) joint extension limits and extensor muscle activation were also investigated. The resulting interphalangeal joint ROM was clinically graded. Active ROM of the finger decreases as tendon shortening increases (ηp2=0.25em0.92), like passive ROM. This results in a clinical reduction of functionality grade from excellent to good at 10 mm of shortening. Blocking MCP joint ROM and extensor activation also showed significant effects on recovered ROM (ηp2=0.25em0.72 and 0.86). Significant two‐way interactions were also observed between shortening and MCP joint blocking (ηp2=0.25em0.80) and between shortening and extensor activation (ηp2=0.25em0.78). Results support clinical recommendations of limiting shortening to 10 mm. While this article provides additional experimental evidence for current surgical recommendations, it also validates a new robotic‐cadaver methodology for predicting active hand recovery in terms of clinical measurements.
