    Abstract:
    PURPOSE OF THE STUDY The aim of the study was to assess the functional outcomes of rehabilitation in patients with surgically treated distal radius fractures in the early postoperative period. We compared the functional outcomes of patients undergoing standard rehabilitation with the group of patients whose postoperative rehabilitation was extended with shoulder girdle exercises of the affected upper limb while the wrist was immobilized. Several indices and variables were used for the assessment of the functional therapeutic outcomes of the affected wrist. MATERIAL AND METHODS Forty patients (32 females and 8 males, the mean age 60.5 years) with distal radius fractures treated by internal fixation using volar surgical approach were involved in the study between 2013-2016. The tested subjects were randomized and split into two groups according to the selected method of rehabilitation. The tested subjects with standard rehabilitation extended with shoulder girdle muscles activation were labelled as group I. It included patients (n = 20) of the mean age 59.8 (age range 42-73 years) with immobilized wrist (i.e. for 3-4 weeks) performing shoulder girdle muscles exercises at the same time. Furthermore, standard kinesiotherapy continued after their fixation was removed. The other tested group, labelled as group II (n = 20), the mean age 61.3 (variation 40-74 years of age) involved patients with distal radius fractures. Only standard rehabilitation was performed in this group as late as their forearm fixation was removed. The following indices and parameters were assessed in the early postoperative period (i.e. by 8 weeks after the fixation removal): wrist and fingers range of motion (ROM), hand grip strength (dynamometry), local swelling, pain, scores of a nine hole peg test (NHPT), and a DASH score. RESULTS After the fixation had been removed, the group I reported statistically significantly higher values of movement compared to the values of the contralateral limb in the following directions: dorsal flexion, palmar flexion, MP joints flexion, flexion of PIP joints (proximal interphalangeal), and flexion of DIP joints (distal interphalangeal). After eight weeks, the group I manifested significantly higher values in dorsal flexion, palmar flexion and ulnar deviation in the wrist. There were no significant differences in other movement directions. The hand grip strength mean value examined with a dynamometer was significantly higher in the group I in the sixth and eighth week of testing (group I - 58.9% strength of a healthy limb after six weeks, or 66.5% after eight weeks). The results in the group II were 49.9% strength of a healthy limb after six weeks, or 56.6% after eight weeks. The group I showed statistically significantly lower values of wrist swelling and higher finger dexterity in the NHPT in all measured weeks. Lower pain intensity in the group I during the measurements was observed. At the same time, this group showed significantly better results in the DASH score. DISCUSSION The results of this study are useful for clinical practice. They confirm a functional relation between the activity of hand muscles and the shoulder muscle activity. The differences in the functional ability of the hand and the functional state of the injured wrist were detected as early as in the early postoperative period. It could be stated that the tested subjects in the group I showed a greater and faster improvement in the physical function of the injured hand. This was also accompanied by a positive psychological effect. We had not found a study of a similar type in the available literature that we could have compared our submitted results to. CONCLUSIONS Shoulder girdle muscles exercises after a distal radius fracture, while wrist is immobilized, can evidently enhance functional capability and accelerate the hand-function restitution. Early functional outcomes of the injured wrist after the rehabilitation with shoulder girdle muscles exercises support the efficiency of this broadened rehabilitation protocol.
